  • Cyclophosphamide-induced male subfertility in mice: An assessment of the
           potential benefits of Maca supplement
    • Authors: A. Y. Onaolapo; B. P. Oladipo, O. J. Onaolapo
      Abstract: Effects of Lepidium meyenii (Maca) on cyclophosphamide (CYP)-induced gonadal toxicity in male mice were investigated. Mice were assigned to six treatment groups: Vehicle control, CYP control, CYP plus oral Maca (500 or 1,000 mg/kg), and oral Maca (500 or 1,000 mg/kg). CYP was administered via the intraperitoneal route (days 1–2), while vehicle or Maca were administered daily for 28 days. On day 28, half of the animals in each group were either sacrificed or paired with age-matched females for fertility assessment. Plasma testosterone assay, sperm analysis and assessment of tissue antioxidant/morphological status were also carried out. CYP administration was associated with oxidative stress, subfertility and morphometric/morphological indices of gonadal injury, while administration of Maca mitigated CYP-induced gonadal toxicity and subfertility. This study shows that Maca is beneficial in the mitigation of CYP-induced male gonadal insufficiency and/or testicular morphological changes; however, further studies will be needed to ascertain its usability for this purpose in humans.

  • Effects of testosterone enanthate and resistance training on myocardium in
           Wistar rats; clinical and anatomical pathology
    • Authors: S. Karbasi; M. Zaeemi, M. Mohri, A. Rashidlamir, Z. Moosavi
      Abstract: This study was performed to determine the effects of 8 weeks testosterone enanthate (TE) injection and resistance training (RT) on cardiac muscle in male Wistar rats. A total of 28 male adult Wistar rats were randomly divided into 4 groups; control + placebo, RT + placebo, TE and TE + RT. Testosterone enanthate (20 mg/kg BW, IM) and placebo (olive oil; 0.2 ml, IM) were injected twice a week for 2 months. The RT consisted of climbing (5 reps/3 sets) a ladder carrying a load suspended from the tail. The serum activities of aspartate aminotransferase (AST), alanine aminotransferase (ALT), lactate dehydrogenase (LDH) and creatine kinase MB (CK-MB) and serum level of creatinine, urea and cardiac troponin I (CTnI) were evaluated. After sacrifice, samples from myocardial muscle were collected for histopathology evaluation. The serum concentration of CTnI and CK-MB activity significantly increased in group RT compared with control (p

  • Impact of melatonin supplementation in the rat spermatogenesis subjected
           to forced swimming exercise
    • Authors: A. Moayeri; T. Mokhtari, A. Hedayatpour, H.-A. Abbaszadeh, S. Mohammadpour, H. Ramezanikhah, S. Shokri
      Abstract: Oxygen consumption increases many times during exercise, which can increase reactive oxygen species. It negatively affects fertility in male athletes. Melatonin is exerting a regulatory role at different levels of the hypothalamic–pituitary–gonadal axis. However, there is no evidence that the protective effects of melatonin persist after long duration exercise on the spermatogenesis. Therefore, this study was conducted to examine the impacts of melatonin on the testis following the administration of swimming exercise. Rats were separated into five different groups, including Control, sham M: received the solvent of melatonin, M: received melatonin, S: the exercise protocol, MS: received melatonin and the exercise protocol. After 8 weeks, animals were scarified and antioxidant enzymes levels of testes, spermatogenic cells apoptosis and sperm quality were measured. Swimming decreased all parameters of spermatozoa. Nevertheless, melatonin could significantly improve the progressive motility of spermatozoa in MS rats. Swimming caused an increased apoptosis of S group and decreased all antioxidant enzymes. Melatonin could drastically reduce apoptosis and increased these enzymes. Therefore, melatonin seems to induce the production of antioxidant enzymes of testicular tissues and diminish the extent of apoptotic changes caused by forced exercise on the testis, which can, in turn, ameliorate the sperm parameters.

  • Association of androgen receptor gene CAG and GGN repeat polymorphism with
           cryptorchidism: A meta-analysis
    • Authors: Qi Wang; Xing Ge, Heng-Xue Wang, Qiao-Mei Shi, Zhen Ding, Li-Chun Xu
      Abstract: Researches on association between variations in the androgen receptor (AR) gene repeat polymorphisms and cryptorchidism (CO) had conflicting results. The aim of this meta-analysis was to analyse the potential effects of AR CAG and/or GGN repeat polymorphism on CO. Studies were independently appraised by two investigators on PubMed, Web of Science, EBSCO databases and Foreign Medical Retrieval System. Case–control studies with measurement of CAG and/or GGN repeat length were included. Weighted mean difference (WMD) and 95% confidence intervals (CIs) for the CAG or GGN repeat polymorphism and CO were calculated. Five reports were included in this analysis. Overall, no difference was identified between patients and fertile men in CAG repeat length. However, when the CO was divided into unilateral and bilateral, longer CAG repeat region was significantly associated with CO in bilateral group (WMD = 0.74; 95% CI, 0.01–1.47; p

  • Association between promoter methylation of MLH1 and MSH2 and reactive
           oxygen species in oligozoospermic men—A pilot study

      Abstract: MLH1 and MSH2 are important genes for DNA mismatch repair and crossing over during meiosis and are implicated in male infertility. Therefore, the methylation patterns of the DNA mismatch repair genes MLH1 and MSH2 in oligozoospermic males were investigated. Ten oligozoospermic patients and 29 normozoospermic donors were analysed. Methylation profiles of the MLH1 and MSH2 promotors were analysed. In addition, sperm motility and seminal reactive oxygen species (ROS) were recorded. Receiver operating characteristic (ROC) analysis was conducted to determine the accuracy of the DNA methylation status of MLH1 and MSH2 to distinguish between oligozoospermic and normozoospermic men. In oligozoospermic men, MLH1 was significantly (p = .0013) more methylated compared to normozoospermic men. Additionally, there was a significant positive association (r = .384; p = .0159) between seminal ROS levels and MLH1 methylation. Contrary, no association between MSH2 methylation and oligozoospermia was found. ROC curve analysis for methylation status of MLH1 was significant (p = .0275) with an area under the curve of 61.1%, a sensitivity of 22.2% and a specificity of 100.0%. This pilot study indicates oligozoospermic patients have more methylation of MLH1 than normozoospermic patients. Whether hypermethylation of the MLH1 promoter plays a role in repairing relevant mismatches of sperm DNA strands in idiopathic oligozoospermia warrants further investigation.

      Abstract: This study evaluated the thermoregulation and spermatogenic changes by scrotal temperature gradient using infrared thermography in testicular compromised bulls. Bulls were insulated (n = 6) for 72 hr and control animals (n = 3) remained without insulation during all the experimental period. Seminal evaluation was performed prior, at insult removal and once per week for 13 consecutive weeks. Mean temperature gradient in insulated animals was lower at the time of insulation removal compared to the week prior and after the insult (p

  • Benign Prostatic Hyperplasia: Long-term follow-up of prostate volume
           reduction after sclerotherapy of the internal spermatic veins
    • Authors: Y. Gat; M. Goren
      Abstract: The purpose was to examine the results of bilateral percutaneous sclerotherapy of the internal spermatic veins on prostate volume and prostatic symptoms. We previously showed that destruction of one-way valves in the internal spermatic veins (varicocele) elevates hydrostatic pressure in the vertical testicular venous drainage system in the erect human. This diverts free testosterone (FT) flow at high concentrations directly from the testes into the prostate. High intraprostatic FT prolongs prostate cell life and increases cell proliferation rate—synergistic effects resulting in increased cell population (BPH). Treatment by interventional radiology (or microsurgery) techniques eliminates this diversion of FT flow to the prostate and reverses these pathologic processes. A total of 206 BPH patients with varicocele underwent bilateral sclerotherapy of the ISV. Of these, 81.5% exhibited significantly reduced prostate volume and improvement in prostatic symptoms (measured by IPSS scores) during follow-up period of 12 to over 24 months. 8% went on to require surgery despite mild post-treatment improvement (TURP). The use of prostate medications along with the treatment may have a combined positive effect. Very large prostate volume and large residual volume may limit degree of improvement. It is concluded that effective treatment of varicocele restores normal supply of testosterone to the prostate solely via its arterial supply, resulting in significant decrease of prostate volume and prostatic symptoms. The procedure is safe with only minor transient side effects.

  • Differentiation of mesenchymal stem cells to germ-like cells under
           induction of Sertoli cell-conditioned medium and retinoic acid
    • Authors: R. Ghaem Maghami; T. Mirzapour, A. Bayrami
      Abstract: The aim of this research was to find a way to differentiate germ cells from umbilical cord Wharton's jelly mesenchymal stem cells (MSCs) to support in vitro spermatogenesis. A small piece of Wharton's jelly was cultured in high-glucose Dulbecco's modified Eagle's medium in present of 10% foetal calf serum. After the fourth passage, the cells were isolated and cultured in Sertoli cell-conditioned medium under induction of two different doses of retinoic acid (10−5, 10−6 m). The differentiation of MSC to germ-like cells was evaluated by expression of Oct4, Nanog, Plzf, Stra8 and Prm1 genes during different days of culture through qPCR. The results showed that there were downregulation of Oct4 and Nanog and upregulation of pre-meiotic germ cell marker (stra8) and haploid cell marker (Prm1) when MSCs are differentiated over time. The expression of Bax gene (an apoptotic marker) was significantly observed in high dosage of retinoic acid (RA). As a result, RA has positive effects on proliferation and differentiation of MSCs, but its effects are related to dosage. The success of this method can introduce umbilical cord MSC as a source of germ cells for treatment of infertility in future.

  • Association between obesity and sperm quality
    • Authors: G. A. Ramaraju; S. Teppala, K. Prathigudupu, M. Kalagara, S. Thota, M. Kota, R. Cheemakurthi
      Abstract: There is awareness of likelihood of abnormal spermatozoa in obese men; however, results from previous studies are inconclusive. Advances in computer-aided sperm analysis (CASA) enable precise evaluation of sperm quality and include assessment of several parameters. We studied a retrospective cohort of 1285 men with CASA data from our infertility clinic during 2016. Obesity (BMI ≥30) was associated with lower (mean ± SE) volume (−0.28 ± 0.12, p-value = .04), sperm count (48.36 ± 16.51, p-value = .002), concentration (−15.83 ± 5.40, p-value = .01), progressive motility (−4.45 ± 1.92, p-value = .001), total motility (−5.50 ± 2.12, p-value = .002), average curve velocity (μm/s) (−2.09 ± 0.85, p-value = .001), average path velocity (μm/s) (−1.59 ± 0.75, p-value = .006), and higher per cent head defects (0.92 ± 0.81, p-value = .02), thin heads (1.12 ± 0.39, p-value = .007) and pyriform heads (1.36 ± 0.65, p-value = .02). Obese men were also more likely to have (odds ratio, 95% CI) oligospermia (1.67, 1.15–2.41, p-value = .007) and asthenospermia (1.82, 1.20–2.77, p-value = .005). This is the first report of abnormal sperm parameters in obese men based on CASA. Clinicians may need to factor in paternal obesity prior to assisted reproduction.

  • Do penile haemodynamics change in the presence of hydrogen sulphide (H2S)
           donor in metabolic syndrome-induced erectile dysfunction'
    • Authors: E. Dayar; E. Kara, G. Yetik-Anacak, N. Hocaoglu, O. Bozkurt, S. Gidener, N. Durmus
      Abstract: Erectile dysfunction (ED) is defined in relation to the metabolic syndrome (metS). Hydrogen sulphide (H2S), a gasotransmitter, has been revealed to get involved in hypertension, insulin secretion and regulation of vascular tone especially in erectile physiology. This study aimed to investigate the effect of H2S on metS-induced ED. Animals were divided into two groups as control and metS, which were fed with standard diet or 60% high-fructose diet for 10 weeks respectively. The metS model was evaluated with biochemical analyses, waist circumference/tibia length ratio and HOMA index. Penile hemodynamic parameters were evaluated by the measurement of intracavernous pressure/mean arterial pressure ratio during cavernous nerve stimulation in the presence and absence of intracavernous injection of NaHS (100 μg/50 μl) and its control 0.9%NaCl (50 μl) in both groups. H2S levels were measured in penile tissues by methylene blue assay. H2S levels were significantly decreased in the penile tissues of the metS group. Decreased intracavernous pressure/mean arterial pressure ratio improved after intracavernous administration of NaHS in the metS group. These results suggest the significant role of H2S in the metS-induced erectile dysfunction that could be a new therapeutic target.

  • Effects of ivermectin and its combination with alpha lipoic acid on
           expression of IGFBP-3 and HSPA1 genes and male rat fertility
    • Authors: Z. K. EL-Maddawy; W. S. H. Abd El Naby
      Abstract: This study was conducted to evaluate the effects of ivermectin (IVM) with therapeutic dose (injected with 0.56 mg/kg b.wt.) either alone or combined with alpha lipoic acid (ALA) (50 mg/kg b.wt daily) on expression of testicular insulin-like growth factor binding protein-3 (IGFBP-3) and heat-shock protein A1 (HSPA1)) genes in the testes, as well as on male rat fertility parameters. Results revealed that expression levels of IGFBP-3 and HSPA1 were significantly increased in testis of the IVM-treated group relative to the control group. Furthermore, injection of ivermectin showed a significant decrease in serum testosterone level, sperm count, motility %, live sperm% and index weight of reproductive organs, and a significant increase in sperm abnormalities. Moreover, IVM induced oxidative stress and pathological alterations in the testes. Meanwhile, the administration of ALA with IVM prevented testicular damage and improved all previous parameters. We concluded that ivermectin has undesirable effects on male fertility and altered expression of IGFBP-3 and HSPA1 genes in the testes, while the administration of alpha lipoic acid can ameliorate the adverse effects of ivermectin.

      Abstract: Cyclophosphamide is a drug used for chemotherapy and as an immune-suppressive in the organ transplantation. Despite its many clinical implications in the treatment of cancers, this drug has toxic effects on the reproductive system. This study aimed to evaluate the effect of ghrelin against the damages caused by cyclophosphamide. In this experimental study, 40 male mice were randomly divided into four groups: (i) control; (ii) cyclophosphamide; (iii) cyclophosphamide + ghrelin; and (iv) ghrelin. Cyclophosphamide (100 mg/kg body weight), once a week, and ghrelin (80 μg/kg body weight), daily, were administered intraperitoneally for 5 weeks. After 5 weeks, the epididymides were removed and the lipid peroxidation, total antioxidant capacity and sperm parameters were examined. The fertility rate was evaluated by performance in vitro fertilisation. In the mice exposed to cyclophosphamide, the number of spermatozoa and viability, as well as total antioxidant capacity, decreased significantly (p

      Abstract: This study aimed to analyse whether the functional quality of spermatozoa is associated with body mass index (BMI). Semen samples were obtained from 1824 men undergoing fertility evaluation/treatment. Semen analysis was performed using World Health Organization (WHO) criteria, and morphology was evaluated with the motile sperm organelle morphology examination (MSOME). The percentages of sperm DNA fragmentation (using TdT (terminal deoxynucleotidyl transferase)-mediated dUTP nick-end labelling (TUNEL) assays), sperm chromatin packaging/underprotamination (using chromomycin A3/CMA3), mitochondrial damage (using MitoTracker Green) and apoptosis (using annexin V) were also assessed. At least 200 spermatozoa were examined in each evaluation. The following BMI values were used as cut-off points: ≤24.9 kg/m2, 25–29.9 kg/m2 (overweight) and ≥30 kg/m2 (obese). High BMI negatively affects sperm concentration, vitality, motility and morphology (p  .05). However, increased BMI is associated with increased mitochondrial damage in spermatozoa (p

  • Health-related quality of life's dependence on socio-economic status and
           demographic characteristics among men with benign prostatic hyperplasia
    • Authors: K. Kosilov; S. Loparev, I. Kuzina, L. Kosilova, M. Ivanovskaya, A. Prokofyeva
      Abstract: This study investigated the effect of socio-economic status (SES) on health-related quality of life (HRQoL) among persons with benign prostatic hyperplasia (BPH). The data were collected by way of surveying persons with BPH aged from 35 to 85 (937) and selected via random sample. The diagnosis was confirmed with the use of I-PSS questionnaires (8–19 points), OABq-AT (≥8 points) and daily urinations. A study on HRQoL was conducted using the SF-36 questionnaire. SES was evaluated using the patients’ ambulance cards (F112U) and tax inspection documents with their written permission. Verification of the viability of the differences in the HRQoL level of patients with different SES was conducted in each age cohort using ANOVA. The goal of the multifactor regressive analysis using least weighted squares was identified as featuring the strongest relationships between SES and HRQoL. In comparing the average regression squares with average error squares, selection of the entry variables was conducted. Among persons with a BPH, the strongest relationship was discovered between profession, level of education, place of residence and HRQoL. A weaker relationship was identified between income and HRQoL, and there was no relationship between marital status and HRQoL. HRQoL among persons with a different level of SES figures aged 65+ proved homogeneous. We can expect HRQoL improvement among persons with BPH while increasing informedness on the possibilities for treating and improving help for workers of industrial and rural production residing in rural areas.

           semen doses and conception rate
    • Authors: M. S. Ghirardosi; M. L. Fischman, A. E. Jorge, D. Chan, H. Cisale
      Abstract: Commercial doses of frozen bull semen for artificial insemination may have a certain percentage of morphological defects, despite being subject to prior selection. The aims of this study were to determine the prevalence of morphological abnormalities in commercial doses (n = 55, r = 2) of dairy and beef bulls, from AI Centers and to determine the possible existence of differences between them, regarding the percentage of abnormal spermatozoa. At least 200 spermatozoa per sample were evaluated using Bengal Rose stain (3% m/v) and light microscopy (×1000 magnification). The mean percentage of abnormal sperm samples from dairy breeds was 7.19% ± 4.91% and from beef breeds was 15.83% ± 9.28%. Significant differences between biotypes were found in the proportion of abnormal spermatozoa, abnormal heads and abnormal midpieces; it could be due to different selection pressure. It was observed that the percentage of abnormal spermatozoa was not a good fertility level predictor for the commercial samples of frozen bovine semen used in this study. In both biotypes, the midpiece abnormalities were the most frequent, mainly its distal flexion (compensable defect). This could be as a result of the effects of freezing and thawing on spermatozoa.

      Abstract: The Internet is an important source of health information with relevant impact on the physician–patient relationship. The German urological associations host one of the most comprehensive platforms for patient information on urological diseases. The aim of the study was to characterise its users and their specific needs. We invited users of the website www.urologenportal.de via pop-up to complete a 26-item online survey to evaluate health-related behaviour, distress and decision-making preferences. We received n = 551 complete responses. The most frequently requested topics were from the field of andrology (45.4%, n = 250). Of these, the most popular topics were circumcision (28.9%, n = 159) and erectile dysfunction (18.1%; n = 100). Overall, 216 users (39.2%) searched for information prior to their first doctor's appointment, and 89.3% (n = 492) preferred autonomous or shared decision-making.

  • Molecular characterisation of a case of dicentric Y presented as
           nonobstructive azoospermia with testicular early maturation arrest
    • Authors: P. Kumar; M. Jain, A. K. Kalsi, A. Halder
      Abstract: The dicentric Y chromosome is the most common cytogenetically visible structural abnormality of Y chromosome. The sites of break and fusion of dicentric Y are variable, but break and fusion at Yq12 (proximal to the pseudoautosomal region 2/PAR 2) is very rare. Dicentric Y chromosome is unstable during cell division and likely to generate chromosomal mosaicism. Here, we report a case of infertile male with nonmosaic 46,XY where chromosome Y was dicentric with break and fusion at Yq12 (proximal to PAR 2). Clinical presentation of the case was nonobstructive azoospermia due to early maturation arrest at the primary spermatocyte stage. Various molecular techniques such as FISH, STS-PCR and DNA microarray were carried out to characterise genetic defect leading to testicular maturation arrest in the patient. The break and fusion was found at Yq12 (proximal to PAR 2) and resulted in near total duplication of Y chromosome (excluding PAR 2). The reason for maturation arrest seems due to CNVs of PARs (gain in PAR 1 and loss of PAR 2) and azoospermia factors (gain).

    • Authors: F. J. Wu; L. T. Kao, S. Y. Sheu, H. C. Lin, S. D. Chung
      Abstract: This study aimed to examine the association of herpes zoster (HZ) with androgen deprivation therapy (ADT) use among patients with prostate cancer (PC), using a population-based data set. The study sample for this study was retrieved from the Taiwan Longitudinal Health Insurance Database 2005. We selected 877 patients with PC who had received ADT as the study group, while 849 patients with PC who had not received ADT served as the comparison group. Each study patient was individually tracked for a 3-year period to discriminate those who subsequently received a diagnosis of HZ. Of the total 1,726 sampled patients, the incidence rate of HZ per 100 person-years was 1.80 (95% CI: 1.41–2.25) during the 3-year follow-up period. In particular, incidence rates of HZ per 100 person-years were 2.36 (95% CI: 1.75–3.13) and 1.24 (95% CI: 0.81–1.81), respectively, for patients with PC who had and those who had not received ADT. Furthermore, Cox proportional hazard regressions showed that the adjusted hazard ratio for an HZ attack during the 3-year follow-up period for patients with PC who had received ADT was 1.88 (95% CI: 1.13–3.11) than those who had not received ADT. We concluded that patients with PC who had received ADT had an increased risk of HZ.

    • Authors: S. Hanafy; J. H. Sabry, E. M. Akl, R. A. Elethy, T. Mostafa
      Abstract: Puberty is the transitional period between childhood and adulthood, a process encompassing morphological, physiological and behavioural development to attain full reproductive capability. This study aimed to assess serum relaxin-3 hormone relationship with male delayed puberty. Sixty males were investigated as two equal groups: males with delayed puberty and healthy matched males as controls. They were subjected to history taking, clinical examination and estimation of serum FSH, LH, testosterone, relaxin-3 hormonal levels. The results showed that the secondary sexual characters in the patients group were at Tanner stages 1–2 and in the healthy controls at Tanner stages 3–5. The mean BMI in the patients group was significantly increased, whereas the mean levels of the span, testicular volume, serum LH, FSH, testosterone as well as relaxin-3 hormonal levels were significantly decreased compared with the healthy controls. Serum relaxin-3 levels showed significant positive correlation with the age, testis volume, span, Tanner stages, serum testosterone, FSH, LH hormones. In addition, serum relaxin-3 levels showed significant negative correlation with BMI. It is concluded that serum level of relaxin-3 hormone is an important mediator in the pathophysiological process of normal puberty being significantly decreased in males with delayed puberty.

    • Authors: S. Ückert; G. la Croce, A. Bettiga, K. Albrecht, R. Buono, F. Benigni, M. A. Kuczyk, P. Hedlund
      Abstract: The endocannabinoid system (ECS), comprising the cannabinoid receptors (CBR), their ligands, and enzymes controlling the turnover of endocannabinoids, has been suggested to be involved in male reproductive function. As information is scarce on the expression of the ECS in human male reproductive tissues, this study aimed to investigate by means of molecular biology (RT-PCR) and immunohistochemistry/immunofluorescence the expression and distribution of CB1 and CB2, GPR55 (an orphan G protein-coupled receptor that recognises cannabinoid ligands) and FAAH (isoforms 1 and 2) in the human seminal vesicles (SV). The specimens expressed PCR products corresponding to CB1 (66 bp), CB2 (141 bp), GPR55 (112 bp), FAAH1 (260 bp) and FAAH2 (387 bp). Immumohistochemistry revealed dense expression of CB1, CB2 and GPR55 located to the pseudo-stratified columnar epithelium and varicose nerves (also characterised by the expression of vasoactive intestinal polypeptide and calcitonin gene-related peptide). Cytosolic staining for FAAH1 and FAAH2 was seen in cuboidal cells of all layers of the epithelium. No immunoreactivity was detected in the smooth musculature or nerve fibres. CB1, CB2, GPR55, FAAH1 and FAAH2 are highly expressed in the human SV. Considering their localisation, the ECS may be involved in epithelial homeostasis, secretory function or autonomic mechano-afferent signalling.

    • Authors: A. A. Ghafarizadeh; G. Vaezi, M. A. Shariatzadeh, A. A. Malekirad
      Abstract: Sperm DNA damage, excessive oxidative stress and decrease in motility ‎may lead to low fertilisation or poor‎ assisted reproductive techniques outcomes in asthenoteratozoospermic ‎men. Selenium was considered as essential element for male reproductive functions. Selenium has important role in enzymatic process for elimination of excessive reactive oxygen species and helps to maintain membrane integrity. The aim of this study was to determine the effect of selenium supplementation on sperm quality, DNA fragmentation, mitochondrial membrane potential and membrane lipid peroxidation during sperm sampling in vitro at different times. In this experimental study, semen samples were collected from 50 asthenoteratozoospermic men. Samples were divided into two groups as control group and test group (incubated with 2 μg/ml selenium at 37°C for 2, 4 and 6 hr). Motility and viability were assessed based on WHO 2010 criteria. Mitochondrial membrane potential, sperm DNA fragmentation and malondialdehyde levels were evaluated in each group. Results revealed that motility, viability and mitochondrial membrane potential were significantly higher in the test group (p

  • Activation of TLR signalling regulates microwave radiation-mediated
           impairment of spermatogenesis in rat testis
    • Authors: H. Wu; D. Wang, Y. Meng, H. Ning, X. Liu, Y. Xie, L. Cui, S. Wang, X. Xu, R. Peng
      Abstract: Microwave radiation could increase the expression of pro-inflammatory cytokines in rat Sertoli cells, which may impair spermatogenesis. However, the mechanisms that microwave radiation induces the cytokine expression in Sertoli cells remain to be clarified. The activation of TLRs by their ligands can trigger a common signalling pathway to upregulate inflammatory cytokines such as IL-1, IL-6, IL-12 and TNF-α. Microwave radiation can increase the expression of TLRs in lymphocytes. The purpose of this study was to determine the effect of microwave radiation on the TLRs in rat testis. We focus on the effect of TLR2-5 (which is expressed relatively highly) by microwave radiation. The results showed that the expression of TLR2-5 and the pro-inflammatory cytokines (IL-1β, IL-6 and TNF-α) was increased both in mRNA and in protein. Furthermore, p-p38, p-ERK1/2, p-JNK and p-NF-κB p65, the key factors of TLR signalling, were also elevated by microwave exposure. And the NF-κB can be induced more dominantly. These results suggest that TLRs signalling can be activated by microwave radiation in testis, which may provide the molecular basis for the in-depth study.

  • The CFTR gene mild variants poly-T, TG repeats and M470V detection in
           Indian men with congenital bilateral absence of vas deferens
    • Authors: A. Gaikwad; S. Khan, S. Kadam, K. Kadam, V. Dighe, R. Shah, V. Kulkarni, R. Kumaraswamy, R. Gajbhiye
      Abstract: The aim of the study was to detect the frequency of the CFTR gene variants poly-T, TG repeats and c.1408A>G p.Met470Val (M470V) in Indian men with congenital bilateral absence of the vas deferens (CBAVD). Men diagnosed with CBAVD (n = 76), their female partners (n = 76) and healthy men from general population (n = 50) were recruited. Genomic DNA was isolated and the polymorphic regions of IVS9- c.1210-12T [5] and M470V were amplified using specific primers followed by Sanger's DNA sequencing. A statistically significant increase in the frequency of heterozygous IVS9- c.1210-12T [5] (39.4%) was observed in CBAVD men as compared to controls (14%). The allelic distribution of c.1210-12T [5], c.1210-12T [7] and c.1210-12T [9] in CBAVD men was 21%, 64.4% and 13% and that in healthy controls was 7%, 73% and 20% respectively. Longest TG repeat c.1210-34TG [13] was found in association with c.1210-12T [5] with an allelic frequency of 5.9% in CBAVD men. We found a significant association of c.1210-34TG [12]/c.1210-34TG [13] - c.1210-12[5] –V470 allele in CBAVD men. Twelve female partners harboured a heterozygous c.1210-12T [5] allele. The study emphasises the need to screen both partners for the polymorphisms M470V, poly-T, TG tract repeats in addition to population-specific known CFTR gene mutations.

      Abstract: To investigate the effect of a high-fat diet and aerobic exercise intervention and its related mechanism on rat germ cell apoptosis. Forty male Sprague-Dawley rats were randomly divided into control group, high-fat diet group, control exercise group and high-fat exercise group. Rats were fed with high-fat diet or were given weight-free swimming. The levels of TG, TC, HDL, LDL and IL-6 in serum of rats were measured. The body weight, body length and inguinal fat weight were measured to calculate the Lee's index and lipid/body weight ratio. The expression of IL-6 mRNA in inguinal fat and IL-6R,Bcl-2 and Bax mRNA in testis was detected by RT-PCR. The morphological structure of testis was observed, and the Johnsen's ten-point score was calculated by HE staining, and the germ cell apoptosis was detected by TUNEL method. We got from the experimental results: a high-fat diet induces obesity and lipid metabolism disorder, alters testis morphological structure and increases germ cell apoptosis in rats. Aerobic exercise improves the lipid metabolism disorder and interferes with germ cell apoptosis by reducing interleukin-6 and interleukin-6 receptor expression.

           values: Abnormal becoming normal
    • Authors: S. Alshahrani; K. Aldossari, J. Al-Zahrani, A. H. Gabr, R. Henkel, G. Ahmad
      Abstract: Reference values of WHO 1999 manual were used for the interpretation of semen analysis until 2010 when new reference values were introduced which have lower cut-off compared to WHO 1999. Therefore, several men who previously were diagnosed abnormal based on their semen analysis have now become normal using new reference values. This study was conducted on semen analyses of 661 men from Middle East region and Pakistan. All semen analyses were reviewed using WHO 1999 and WHO 2010 criteria. Results showed that based on new criteria, 19% of the population changed classification from abnormal to normal when all normal semen parameters were considered. When at least one or more abnormal semen parameters were considered, of the total 661, 44% (288) of the population changed its classification from abnormal to normal with shift from WHO 1999 to 2010 criteria. These findings show that using new cut-off values, many more men are considered normal, but using old criteria (WHO 1999), the same men would be classified as abnormal. This warrants further discussion over the investigations and management plans for patients whose semen analyses fall below WHO 1999 but above WHO 2010 cut-offs.

  • Semen quality and infertility status can be identified through measures of

    • Authors: M. Arafa; A. Agarwal, S. Al Said, A. Majzoub, R. Sharma, K. B. Bjugstad, K. AlRumaihi, H. Elbardisi
      Abstract: Standard analyses for evaluating semen quality require technical expertise and are interpretive in nature. Oxidative stress (OS) alters many of the semen parameters; thus, a measure of OS could be an indicator of semen quality. Static oxidation-reduction potential (sORP) is a universal measure of OS traditionally used in environmental applications but is increasingly used in biomedical studies. sORP was measured to determine how well it associates with semen quality and if it differentiates semen from infertile patients and fertile donors. All study participants (Infertile, n = 365 and Fertile, n = 50) underwent standard semen analyses, and sORP was measured in unprocessed semen. In infertile patients, sORP increased with decreased total sperm number, motility and morphology. sORP values were higher in samples with abnormal quality (low number, motility and/or normal morphology) compared with those of normal quality. Infertile patients had higher sOPR values compared to fertile donors. A sORP cut-off value of 1.38 mV/106 sperm/ml can differentiate normal from abnormal semen samples, while a cut-off value of 1.41 mV/106 sperm/ml, can differentiate between infertile and fertile semen samples. In conclusion, sORP provides a quick and unbiased indicator of semen quality that can be a beneficial addition to semen analysis to determine semen quality and fertility status.

      Abstract: The pressure pattern in varicocele veins of infertile patients and its correlation with semen quality and testicular blood flow was determined. Consecutive patients at andro-urology clinic of a teaching hospital undergoing microsurgical varicocelectomy were included. Their semen quality and testicular blood flow were determined. Peak systolic velocity (PSV) and resistive index (RI) of subcapsular and intraparenchymal branches of testicular artery were noted by colour Doppler ultrasonography. During surgery before ligation of varicocele veins, intravenous pressures of internal spermatic (ISV) and external spermatic (ESV) veins were determined at baseline and after Valsalva manoeuvre. Thirty patients, 20–45 years old, were evaluated. Baseline pressure for maximum dilated ISV (A), less dilated ISV (B) and ESV was 15.93 ± 6.34, 12.38 ± 4.60 and 12.92 ± 5.65 mm.

  • Pathological changes in Sertoli cells and dysregulation of divalent metal
           transporter 1 with iron responsive element in the testes of idiopathic
           azoospermia patients
    • Authors: T. Jing; P. Wang, Y. Liu, J. Zhao, X. Niu, X. Wang
      Abstract: Iron is essential for rapidly dividing spermatocytes during normal mammalian spermatogenesis. Decreased transferrin and transferrin receptor levels were observed in seminal plasma from idiopathic azoospermia (IA) patients, suggesting disturbed iron metabolism in IA testes. However, how Sertoli cells (SCs) contribute to the iron homoeostasis in IA is still unclear. In this study, we analysed 30 IA and 30 age-matched obstructive azoospermia (OA) patients undergoing testicular sperm aspiration (TESA). SCs hyperplasia was indicated by higher SC density and Ki-67 labelling index in the IA TESA specimens. The attenuated expression of superoxide dismutase (SOD) suggested an impaired antioxidative capacity in IA testes. We further detected increased levels of iron importer divalent metal transporter 1 with iron responsive element (DMT1 + IRE) in IA testes, whereas the increasing trend of iron exporter ferroportin 1 (FPN1) was not statistically significant. Next, we demonstrated that iron regulatory protein 1 (IRP1) and hypoxia-inducible factor-1α (HIF-1α), which can potentially bind to the IRE and hypoxia-responsive element in the DMT1 + IRE mRNA, were both up-regulated in IA testes. Unexpectedly, HIF-2α was down-regulated in IA testes. These results indicate that there is a dysregulation of DMT1 + IRE in IA testes, which might due to the up-regulation of IRP1 and HIF-1α.

    • Authors: P.-B. Sun; H.-M. Xu, K. Li, H.-C. Li, A.-J. Chen, M.-J. Chen, H.-T. Dai, Y. Ni
      Abstract: Cystic fibrosis transmembrane conductance regulator (CFTR) is relevant to sperm quality, sperm capacitation and male fertility. However, it is still unknown whether CFTR can be a potential parameter for fecundity prediction in healthy couples. In this study, 135 healthy couples were divided into groups according to their fertility. We demonstrated that the sperm CFTR expression level of healthy males who never impregnated their partners (49 cases, 38.68 ± 2.71%) was significantly lower than that of fertile men (86 cases, 46.35 ± 2.32%). Sperm CFTR expression level accurately corresponded with fertility through the logistic regression model. Receiver operating characteristic (ROC) curve analysis showed that the cut-off value of sperm CFTR expression level for fecundity prediction was 43.75%. Furthermore, cumulative pregnancy rates (CPRs) of CFTR> 43.75% group and CFTR ≤ 43.75% group during the follow-up periods were 80.6% and 49.3% respectively. Meanwhile, the mean time to pregnancy (TTP) of CFTR ≤ 43.75% group (26.79 ± 2.35) was significantly longer than that of CFTR> 43.75% group (16.46 ± 2.42). Therefore, sperm CFTR expression level is relevant to fecundity of healthy couples and shows potential predictive capacity of fecundity.

      Abstract: To study the outcome of FISH sperm examination in cases with sperm pathology and outline the potential correlation with certain chromosomal defects. A retrospective study of prospectively collected data was performed in IAKENTRO, Infertility Treatment Center. Rates of abnormal FISH semen examination were compared between male infertility patients and fertile controls. Detection of abnormal FISH semen examination as well as each chromosomal abnormality detected was correlated with each sperm deficiency (asthenozoospermia, oligozoospermia and teratozoospermia) in a univariate regression model. There were 72 male partners included, of which 52 male infertility patients and 20 controls. The rate of abnormal sperm FISH examination was significantly higher in patients’ group (55.8% vs. 15.0% for controls, p = .002). Asthenozoospermia, oligozoospermia and teratozoospermia were significantly correlated with detection of abnormal FISH examination (p = .004, p = .01 and p

    • Authors: T. R. Huang; W. Li, B. Peng
      Abstract: Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a common clinical syndrome, and the mechanisms underlying the relationship between CP/CPPS and ED are still unclear. This study aimed to investigate the differential expression of 40 inflammatory mediators in patients with CP/CPPS and to demonstrate whether these mediators related to the severity of erectile function. Eighty cases of patients with CP/CPPS were selected, including 40 cases of IIIA and 40 cases of IIIB, with 20 cases of healthy men as controls. After collecting their expressed prostatic secretion, cytokines levels in EPS were determined by ELISA using ELISA kits. The IIEF-5 questionnaire was used to evaluate erectile function. IIEF-5 scores were significantly lower in the IIIA and IIIB groups than those in the control group. The expression of IL-8, IL-1β and ICAM-1 was markedly higher in the IIIA and IIIB groups than in the control group. The expression of IL-8, IL-1β and ICAM-1 in the IIIA group was higher than that in the IIIB group. The expression of IL-8, IL-1β and ICAM-1 was negatively correlated with IIEF-5 scores in both IIIA and IIIB patients. In conclusion, IL-8, IL-1β and ICAM-1 are possible indicators for the clinical diagnosis of CP/CPPS and evaluation of erectile function on patients with CP/CPPS.

    • Authors: T. G. Bergstein-Galan; L. C. Bicudo, L. Rodello, R. R. Weiss, S. D. Bicudo
      Abstract: The aim of this study was to evaluate the effect of four methods of sperm selection, on the integrity and stability of the plasma membrane, integrity of the acrosomal membrane and spermatic morphology in frozen/thawed ovine semen. Two types of colloidal silica: colloidal silica–silane and colloidal silica–polyvinylpyrrolidone (PVP), and two aliquots: 1 and 4 ml, were used for sperm selection. Probes FITC-PSA and PI were used to measure the integrity of the plasma and acrosomal membranes. Plasma membrane stability was measured, using fluorescent probes M540 and YOPRO1. Effective reduction in the incidence of spermatozoa with acrosomal pathologies was only achieved using 1 ml colloidal silica–silane. All methods were efficient in select viable and unreacted spermatozoa. Only methods using 1 ml of silica were efficient in decrease spermatozoa stained by PI (death). Methods using silica colloidal–silane were more efficient to decrease apoptotic cells after selection when compared to silica colloidal–PVP. In conclusion, sperm selection in colloidal silica–silane and colloidal silica–PVP improved sperm quality when compared to the controls. The method using 1 ml of colloidal silica–silane is the preferred method because its effectiveness and lower cost.

We determined the expression levels of mitochondrial and nuclear OGG1 isoforms in spermatozoa collected from cauda epididymis in rats exposed to chronic hypobaric hypoxia (CHH) for 5, 15 and 30 days.

  • Effect of paracetamol on semen quality
    • Authors: S. A. Banihani
      Abstract: Several published studies, both direct and indirect, have connected paracetamol, also named acetaminophen, a commonly used over-the-counter analgesic and antipyretic medication, with semen quality and male infertility, although as yet this connection is unclear. This review addresses the effect of paracetamol on semen quality and hence on male factor infertility. We searched the MEDLINE database from January 1980 through January 2017 for English-language articles using the key words “paracetamol” and “acetaminophen” versus “sperm.” References from articles were used only if relevant. In summary, paracetamol, when used at high doses, appears to change semen quality, particularly sperm morphology, and hence its fertilising ability. Such effect of paracetamol on semen quality may occur by suppressing testosterone synthesis, inducing oxidative stress, provoking apoptosis of spermatocytes, reducing nitric oxide production and inhibiting prostaglandin synthesis. Further research, particularly clinical research, will be very important to confirm these effects.

  • Pentoxifylline increases the level of nitric oxide produced by human
           spermatozoa
    • Authors: S. A. Banihani; R. F. Abu-Alhayjaa, Z. O. Amarin, K. H. Alzoubi
      Abstract: Pentoxifylline (PF) is a xanthine derivative drug primarily used to treat peripheral vascular disorders. It is currently used in assisted reproductive technologies to enhance human sperm motility. However, the mechanism by which this enhancement occurs is not fully understood. Given that nitric oxide has been identified as a trigger to sperm motion, we asked whether nitric oxide modulates the stimulatory effect of PF on sperm motility. A total of 41 semen samples from infertile males were studied. Nitric oxide production in the presence of 5 mm PF was tested using different bio-analytical methods (spectrophotometry, fluorometry and fluorescence microscopy). The spectrophotometric determination showed higher levels of nitrite, an indirect measure for nitric oxide, in sperm samples supplemented with PF compared to controls. The fluorometric experiment showed higher 4, 5-diaminofluorescein triazole, a product from the reaction between nitric oxide and 4, 5-diaminofluorescein diacetate, after adding PF to spermatozoa. The fluorescence microscopy images of the spermatozoa supplemented with PF showed higher green fluorescence, indicating higher 4, 5-diaminofluorescein triazole levels, compared to controls. It is concluded that PF enhances nitric oxide production in human spermatozoa, which explains, at least in part, the mechanism by which PF stimulates human sperm motility.

    • Authors: E. Aliabadi; S. Jahanshahi, T. Talaei-Khozani, M. Banaei
      Abstract: Cryopreservation is used to preserve the spermatozoa; however, it leads to a reduction in sperm quality. L-carnitine (LC) influences sperm motility and preserves the sperm membrane and DNA integrity. The objectives of this study were to evaluate the protective effects of LC on the membrane integrity of normal human spermatozoa and compare it with pentoxifylline (PT) during cryopreservation. Thirty normal semen samples, prepared by swim-up procedure, were divided into three aliquots: a control without any treatment and two experimental aliquots that were incubated in PT or LC for 30 min. All aliquots were cryopreserved and thawed after 48 hr. To evaluate the percentages of intact, acrosomal-reacted and capacitated spermatozoa, lectin histochemistry and flow cytometry were performed by wheat germ agglutinin, peanut agglutinin and Con A. Statistical analyses were performed using ANOVA. LC supplementation elevated the percentage of noncapacitated spermatozoa compared with control and PT-treated samples and the percentages of acrosomal intact spermatozoa compared with PT-treated samples. PT pre-treatment improved the motility but not membrane integrity. LC supplementation reduced the percentages of acrosomal-reacted spermatozoa compared with the control and PT-treated samples. Although LC did not improve motility, it protected the plasma membrane and acrosomal integrity. Therefore, LC may be the superior choice compared to PT for maintaining the sperm integrity.

    • Authors: A. Zeyad; M. F. Hamad, M. E. Hammadeh
      Abstract: The purpose of this study was to detect the effects of bacterial infection on human sperm nuclear protamines and DNA fragmentation. In this study, 120 semen samples were collected from unselected male partners of couples consulting for infertility in infertility and obstetrics clinic. All the samples were screened bacteriologically according to World Health Organization guidelines, and also sperm parameters and DNA fragmentation were evaluated. The concentrations of protamines P1 and P2 were quantified using acid urea acrylamide gel electrophoresis. Of a total number of 120 sample, 36 (30%) of them were infected with bacteria. Nine species of bacteria belonging to five genera, Staphylococcus, Escherichia, Streptococcus, Enterococcus and Klebsiella, were identified. The comparison between infected (36) and noninfected (84) samples appeared the negative impact of bacterial infection on sperm parameters and P1/P2 ratios. The percentages of P1/P2 ratio abnormality were significantly higher in infected patients. Sperm concentration, motility, progression and chromatin condensation were significantly lower in infected patients (p

  • Effects of testosterone enanthate treatment in conjunction with resistance
           training on thyroid hormones and lipid profile in male Wistar rats
    • Authors: M. Zarei; M. Zaeemi, A. Rashidlamir
      Abstract: This study was conducted to determine the effects of 8-week administration of testosterone enanthate (TE) in conjunction with resistance training on thyroid hormones and lipid profiles. Sixty male adult Wistar rats were randomly divided into six groups: C: olive oil, RT: resistance training + olive oil, LD: TE (20 mg/kg), HD: TE (50 mg/kg), RT + LD: RT + TE (20 mg/kg), RT + HD: RT + TE (50 mg/kg). The RT consisted of climbing (5 reps/3 sets) a ladder carrying a load suspended from the tail. At the end, blood specimens were obtained from the orbital sinus and serum concentration of T4, T3, TSH and lipid profiles was determined. The serum concentration of TSH significantly increased in RT + HD group compared to C, and the serum concentration of T4 significantly decreased in LD, HD, RT + LD and RT + HD groups compared to the C and RT groups (p

  • Co-administration of caffeine and caffeic acid alters some key enzymes
           linked with reproductive function in male rats

      Abstract: This study assessed the effects of caffeine combined with caffeic acid on some biomarkers of male reproductive function using normal albino Wistar rats. Rats were divided into four groups (n = 6) and treated for seven successive days; group 1 represents the control rats; group 2 rats were treated with 50 mg/kg body weight (BW) of caffeine only; group 3 rats were treated with 50 mg/kg BW of caffeic acid, while the rats in group 4 were cotreated with an equal combination of caffeine and caffeic acid. The results revealed significant increase in reproductive hormone, testicular and epididymal nitric oxide levels of the rats. Moreover, decreased oxidative stress in the testes and epididymides of the treated rats was evidenced by significant increase in total and nonprotein thiol levels, catalase and superoxide dismutase activities. Similarly, decreased testicular cholesterol level with concomitant elevation in testicular steroidogenic enzyme activities, glycogen and zinc levels were observed in the treated rats. No morphological changes were observed as revealed by the photomicrographs from light microscopy in treated rats. Nevertheless, the combination therapy exhibited additive/synergistic effect on these biochemical indices than when they were administered singly. This study suggests the combination therapy of caffeine and caffeic acid at the dose tested for improving male reproductive function.

      Abstract: SummaryThe study was designed to evaluate the effects of metformin on apoptosis and epididymal sperm quality in a rat testicular ischaemia/reperfusion (I/R) injury model. A total of 72 male rats were divided into four groups (n = 18 for each group): group 1 (sham-operated group), group 2 (metformin group), group 3 (torsion/detorsion [T/D] + saline) and group 4 (T/D + 300 mg kg−1 metformin). Testicular torsion was achieved by rotating the right testis 720° in a clockwise direction for 1 hr. Tissue malondialdehyde (MDA) level and caspase-3 activity increased and the activities of catalase, superoxide dismutase and glutathione peroxidase decreased in comparison with sham-operated group 4 hr after detorsion (p

  • Effect of the age of broodstock males on sperm function during cold
           storage in the trout (Oncorhynchus mykiss)
    • Authors: J. Risopatrón; O. Merino, C. Cheuquemán, E. Figueroa, R. Sánchez, J. G. Farías, I. Valdebenito
      Abstract: The knowledge of sperm quality in the broodstock males of different ages is a prerequisite to identify the reproductive ability of cultivated fish for the hatchery management. Thus, in this work, we analysed sperm function of the semen stored of broodstock males of rainbow trout (Oncorhychus mykiss) in different reproductive ages (2, 3 and 4 years old). Sperm samples of each reproductive age were stored in Storfish® during 10 days at 4°C, and then, motility, viability, mitochondrial function (MMP), superoxide anion (O2−) level and DNA fragmentation (DNAfrag) were assessed. The results demonstrated that sperm function parameters were affected significantly by the age of the males and the time of storage. Motility, viability and MMP significantly decreased, and DNAfrag and O2− level increased with the age increment and the time of storage. In conclusion, sperm quality of 2 and 3 years old were superior to those of 4 years old, based on higher quality of various sperm functions such as motility, viability, MMP, DNA integrity and level O2− during short-term storage. This information must be considered for optimum utilization of broodstock males in aquaculture.

    • Authors: P. Watcho; F. X. Kemka, P. B. Deeh Defo, M. Wankeu-Nya, P. Kamtchouing, A. Kamanyi
      Abstract: This study was undertaken to evaluate the effects of Aframomum melegueta on male rat ejaculation using in/ex copula techniques. For the in copula experiment, rats were orally treated with aqueous or methanolic extract (20 and 100 mg/kg) of A. melegueta for 14 days. Each rat was mated with a primed receptive female on days 0, 7 and 14 of treatment, and the ejaculatory latency and post-ejaculatory interval were measured. In the ex copula experiment, the electromyography of the bulbospongiosus muscles and intraseminal pressure were recorded in spinal rats after mechanical (urethral and penile) and pharmacological stimulations (intravenous injection of dopamine (5 mg/kg) and, aqueous or methanolic extract of A. melegueta, 2.5; 5; 10 and 20 mg/kg). Furthermore, the effect of dopamine on fictive ejaculation was monitored in rats orally pre-treated with A. melegueta extracts (20 and 100 mg/kg) for 7 or 14 days. Treatment with the aqueous or methanolic extract of A. melegueta significantly decreased the ejaculatory latency (p

      Abstract: We investigated the prevalence of 5HT2C receptor gene polymorphisms in Egyptian patients with lifelong premature ejaculation. A total of 350 participants were enrolled in a prospective study. Two hundred and forty-five cases with lifelong premature ejaculation joined this study, in addition to 105 controls. We instructed the partners of the cases to measure the IELT of the first intercourse only using a stopwatch for 1 month. Genotyping was carried out at the end of the study. The results showed that the majority of the patients and controls were Cys/Cys. A highly significant statistical association was found between the studied gene polymorphisms and IELT among cases (p-values = .009). The study emphasised the potential role of 5HT2C receptor gene polymorphisms in patients with lifelong premature ejaculation.

  • Roles of Fas/FasL-mediated apoptosis and inhibin B in the testicular
           dysfunction of rats with left-side varicocele
    • Authors: J. Zhang; P. P. Jin, M. Gong, J. H. Guo, K. Fang, Q. T. Yi, R. J. Zhu
      Abstract: We investigated the role of the Fas/FasL signalling pathway and inhibin B expression in rats with an experimentally induced left-side varicocele. Forty-five Sprague Dawley (SD) male rats were randomly divided into three groups in average: control group, sham group and experimental group. The expression of inhibin B in the rat left testis was analysed at the mRNA and protein levels by reverse transcription–polymerase chain reaction (RT-PCR) and Western blotting respectively. The expressions of Fas, FasL and caspase-3 in the left testis were measured by RT-PCR and immunofluorescence. The apoptosis index (AI) was measured by terminal deoxynucleotidyl transferase dUTP nick end labelling (TUNEL). Both the mRNA and protein of inhibin B were significantly reduced in the experimental group compared with that in the control group or the sham group. The expression of Fas, FasL and caspase-3 in the experimental group was significantly increased compared to that in the control group or the sham group. The concentration of serum inhibin B was also inversely related to circulating FSH concentrations and positively correlated with sperm count. It is concluded that Fas/FasL system may play an important role in apoptosis of rats with experimental varicocele and inhibin B could reflect spermatogenesis function.

    • Authors: D. M. Dinesh Yadav; M. N. Muralidhar, S. M. V. K. Prasad, K. Rajender Rao
      Abstract: Obesity is a multifactorial disorder associated with increased body adiposity, chronic oxidative stress which contributes to impaired fertility in males. Diet restriction and anti-oxidant supplementations are known to protect obese subjects from oxidative stress and improves fertility. However, the role of oxidative stress and the age of intervention in restoring male fertility are poorly understood. This study was aimed to assess the effect of diet restriction on fertility with respect to the age of intervention, body composition and oxidative stress using WNIN/Ob obese mutant rat strain. Unlike lean and carrier phenotypes, obese rats are hyperphagic, hyperlipaemic and infertile. Male obese rats aged for 35, 60 and 90 days were fed either ad libitum or diet restricted for 6 weeks. Upon diet restriction mean body weight, total body fat percentage, circulatory lipids and oxidative stress markers were significantly reduced and it follows the order as 35

      Abstract: This study aimed to describe spinal cord injured patients’ semen characteristics before and after cryopreservation, and assisted reproductive technology cycles outcome compared to the infertile population. Data about sperm analysis and assisted reproductive technology (ART) cycles outcomes for 78 men with spinal cord injury referred for sperm cryopreservation between 1998 and 2013 were retrospectively analysed and compared with a reference group consisting of every Intra Cytoplasmic Sperm Injection (ICSI) cycle performed in our in vitro fertilization unit over the 2009–2014 period. Semen was collected by penile vibratory stimulation (PVS), electroejaculation or via testis biopsies. Fresh and frozen semen parameters and ART outcomes with frozen-thawed sperm were measured. Patients were divided into three groups according to the sperm retrieval methods: 37 electroejaculations, 37 PVSs and four surgical sperm retrievals. Low ejaculate volume was observed in 33% of the patients, and oligozoospermia in 37% of the patients. Specimens from 77 of the patients contained motile sperm and were therefore frozen for future use. There was no statistical difference for any of the fresh semen parameters between all groups. Twenty of them underwent ICSI leading to five live births, while four underwent intrauterine insemination. ART with frozen-thawed spermatozoa can provide men with SCI with comparable results as in the infertile population.

  • Effect of Typha capensis (Rohrb.)N.E.Br. rhizome extract F1 fraction on
           cell viability, apoptosis induction and testosterone production in
           TM3-Leydig cells
    • Authors: A. Ilfergane; R. R. Henkel
      Abstract: Typha capensis (Rohrb.)N.E.Br. (bulrush) is used by traditional healers in Southern Africa to treat male reproductive problems. This study aimed at investigating the effects of T. capensis on TM3-Leydig cells. T. capensis rhizome crude extract obtained from autumn, winter, spring and summer harvest was fractionated using HPLC into four fractions, and TM3-Leydig cells were incubated with different concentrations of the F1 fraction (0.01, 0.02, 0.1, 1, 10 and 100 μg/ml) for 24, 48 and 96 hr respectively. The following parameters were evaluated: cell morphology, viability (MTT assay), testosterone production (testosterone ELISA test), apoptosis (Annexin V-Cy3 binding) and DNA fragmentation (TUNEL assay). Results revealed that the summer harvest obtained the highest amount of extract. The F1 fraction of all harvests was the most effective. This fraction significantly enhanced testosterone production in TM3 cells in a dose-dependent manner with maximum effect at 0.1 μg/ml. At higher concentrations, lower testosterone production was observed. Cell viability including apoptosis was not affected at concentrations used by the traditional healers to treat patients. This study shows that T. capensis enhanced testosterone production and might be useful to treat male infertility and ageing male problems.

  • Bisphenol A induced oxidative stress and apoptosis in mice testes:
           Modulation by selenium
    • Authors: S. Kaur; M. Saluja, M. P. Bansal
      Abstract: Spermatogenesis, a highly coordinated process, is prone to environmental insults which may lead to impaired spermatogenesis or, at worst, infertility. Bisphenol A (BPA) is a well-known global environmental toxicant and a ubiquitous oestrogenic chemical. This study evaluated the role of selenium (0.5 ppm sodium selenite/kg diet) on spermatogenesis after BPA treatment in different groups of male BALB/c mice: control, selenium, BPA and selenium+BPA. Markers of oxidative stress and apoptosis were evaluated in testis after BPA treatment. Significant decrease in sperm concentration and motility and increased reactive oxygen species(ROS) and LPO levels were seen in BPA group. Histopathological changes revealed extensive vacuolisation, lumen devoid of spermatozoa and decreased germ cell count, confirmed by testicular germ cell count studies. TUNEL assay for apoptosis showed increased number of TUNEL-positive germ cells in BPA group with increased percentage apoptotic index. However, in Se+BPA group, histopathological studies revealed systematic array of all germ cells, preserved basement membrane with relatively less vacuolisation, improved sperm parameters and ROS and LPO levels and decreased number of TUNEL-positive germ cells. These results clearly demonstrate the role of selenium in ameliorating oxidative stress and apoptosis induced upon BPA treatment in mice and can be further used as therapeutic target in male infertility.

  • Mitochondria-targeted antioxidant SkQ1 improves spermatogenesis in Immp2l
           mutant mice
    • Authors: Yaodong Jiang; Chunlian Liu, Bin Lei, Xian Xu, Baisong Lu
      Abstract: Previous studies have confirmed that spermatogenesis in homozygous Immp2l mutant male mice was normal at the age of 6 months, but was significantly abnormal at the age of 13 months. Meanwhile, oxidative stress is reported to be involved in spermatogenic impairment in old mutant mice. However, it is unclear whether antioxidant treatment is a suitable intervention for improving spermatogenesis in old mutant mice. This study sought to investigate the effect of mitochondria-targeted antioxidant SkQ1 on spermatogenesis in homozygous Immp2l mutant mice. Immp2l mutant mice were treated with the mitochondria-targeted antioxidant SkQ1 from the age of 6 weeks until 13 months. SkQ1 treatment significantly improved spermatogenesis in old Immp2 l mutant mice. Moreover, SkQ1 treatment improved the morphology of testicular seminiferous tubules, significantly reduced the apoptosis of germ cells and increased the level of GPX4 expression in old Immp2 l mutant mice. In conclusion, our data suggest that the mitochondria-targeted antioxidant SkQ1 is effective in improving spermatogenesis in Immp2 l mutant mice and might be used for the treatment of male infertility.

    • Authors: G. A. Ujah; V. U. Nna, M. I. Agah, L. O. Omue, C. B. Leku, E. E. Osim
      Abstract: Cadmium chloride (CdCl2) has been reported to cause reproductive toxicity in male rats, mainly through oxidative stress. This study examined its effect on sexual behaviour, as one of the mechanisms of reproductive dysfunction, as well as the possible ameliorative effect of quercetin (QE) on same. Thirty male Wistar rats (10 weeks old), weighing 270–300 g, were used for this study. They were either orally administered 2% DMSO, CdCl2 (5 mg/kg b.w.), QE (20 mg/kg b.w.) or CdCl2+QE, once daily for 4 weeks, before sexual behavioural studies. The 5th group received CdCl2 for 4 weeks and allowed 4-week recovery period, before sexual behavioural test. Rats were sacrificed after sexual behavioural studies. The blood, testis and penis were collected for biochemical assays. Cadmium increased mount, intromission and ejaculatory latencies, but reduced their frequencies, compared to control. Serum nitric oxide increased, while penile cyclic guanosine monophosphate reduced in the CdCl2-exposed rats, compared to control. CdCl2 increased testicular cholesterol, but reduced 3β-hydroxysteroid dehydrogenase (3β-HSD) and 17β-HSD activities, and testosterone concentration. QE better attenuated these negative changes compared to withdrawal of CdCl2 treatment. In conclusion, CdCl2 suppressed steroidogenesis, penile erection and sexual behaviour, with poor reversal following withdrawal, while QE attenuated these effects.

    • Authors: Y. S. Park; S. H. Lee, C. K. Lim, H. W. Choi, J. H. An, C. W. Park, H. S. Lee, J. S. Lee, J. T. Seo
      Abstract: This study was performed to evaluate the independent influence of paternal age affecting embryo development and pregnancy using testicular sperm extraction (TESE)-intracytoplasmic sperm injection (ICSI) in obstructive azoospermia (OA) and nonobstructive azoospermia (NOA). Paternal patients were divided into the following groups: ≤30 years, 31–35 years, 36–40 years, 41–45 years and ≥46 years. There were no differences in the rates of fertilisation or embryo quality according to paternal and maternal age. However, clinical pregnancy and implantation rates were significantly lower between those ≥46 years of paternal age compared with other age groups. Fertilisation rate was higher in the OA than the NOA, while embryo quality, pregnancy and delivery results were similar. Clinical pregnancy and implantation rates were significantly lower for patients ≥46 years of paternal age compared with younger age groups. In conclusion, fertilisation using TESE in azoospermia was not affected by the independent influence of paternal age; however, as maternal age increased concomitantly with paternal age, rates of pregnancy and delivery differed between those with paternal age

      Abstract: Several studies have associated telomere shortening with alterations in reproductive function. The objective of the present study was to determine telomere length (TL) in spermatozoa selected by either density-gradient centrifugation (DGC) or swim-up. The analysis of TL was performed using quantitative fluorescent in situ hybridisation (qFISH) using PNA probes in combination with a chromatin decompaction protocol in sperm cells. Results of TL were 24.64 ± 5.00 Kb and 24.95 ± 4.60 Kb before and after DGC, respectively, and 19.59 ± 8.02 Kb and 20.22 ± 5.18 Kb before and after swim-up respectively. Sperm selected by DGC or swim-up did not show any significant differences in TL as compared to nonselected sperm (p > .05). Negative correlations between TL and sperm motility (r = −.308; p = .049) and concentration (r = −.353; p = .028) were found. Furthermore, exposure of sperm to increasing concentrations of hydrogen peroxide during incubation resulted in a reduction in TL. These data indicate that oxidative stress may be one of the main factors involved in the reduction of TL in sperm. Preliminary clinical results from patients included in this study indicate that TL was shorter in spermatozoa from couples who never achieved a pregnancy compared to couples who did achieve at least one natural pregnancy (p

      Abstract: Genital abnormalities such as congenital uni/bilateral absence of the vas deferens are very rare in Klinefelter's syndrome. Here, we report three cases of Klinefelter's syndrome with unilateral absence of the vas deferens. All cases had small testicles, and unilateral vas deferentia were not palpable. Hormonal evaluations revealed hypergonadotropism. One case had elevated prolactin level, and pituitary adenoma was detected by magnetic resonance imaging. All cases were diagnosed as Klinefelter's syndrome (one of them had mosaicism) cytogenetically, and some CFTR gene mutations were detected. To our knowledge, this is the first case series of both conditions existing simultaneously.

    • Authors: M. Laqqan; E. F. Solomayer, M. Hammadeh
      Abstract: The purpose of this study was to assess the relationship between alterations in sperm DNA methylation levels and sperm count and sperm motility. Five CpG sites underwent deep bisulphite sequencing to validate the observed methylation difference in 78 samples (28 proven fertile males “controls,” and 50 subfertile males “cases”). The results showed that variation in methylation levels was found in more than one CpG: the DNA methylation levels in CpG1, CpG2 and CpG3 of the PRRC2A gene-related amplicon showed high significant differences in the case group compared to the control group (p ≤ .0001, p ≤ .003, and p ≤ .0001 respectively). Moreover, three CpGs of the four CpGs tested within the ANXA2 gene-related amplicon (CpG1, CpG3 and CpG4) were significantly different (p ≤ .002, p ≤ .001, and p ≤ .0001, respectively) in the case group compared to the control group. In addition, a significant difference was found in seven CpGs of the twenty-two CpGs tested within the MAPK8Ip3 gene-related amplicon, besides six CpGs of the ten CpGs tested within the GAA gene-related amplicon between case and control groups. In conclusion, this study identifies that CpGs have a significantly different in methylation levels of sperm DNA for subfertile males.

  • Microsurgical varicocelectomy for clinical varicocele: A review for
           potential new indications
    • Authors: X. Wan; H. Wang, Z. Ji
      Abstract: Microsurgical varicocelectomy is considered the gold-standard technique treating varicocele in both adults and adolescents, due to relatively more favourable outcomes and lower post-operative recurrence and complication rates. Despite of mounting literature on this topic, several aspects are still not well defined. We summarised the most recent literature and presented findings that might extend its indications. Microsurgical varicocelectomy and intracytoplasmic sperm injection are both effective to father a child for infertile men with clinical varicocele even for those with worst condition of spermatozoa, nonobstructive azoospermia, and prior varicocele repair has substantial benefits for couples with a clinical varicocele. Microsurgical subinguinal and inguinal varicocelectomy seem to have comparable effectiveness for adolescents and infertile men with varicoceles. However, the subinguinal approach may have some advantages to deal with painful varicocele. The superior outcomes of bilateral varicocelectomy for patients with clinical left varicocele and concomitant clinical right varicocele are justified, while the benefit is still uncertain for concomitant subclinical right varicocele. Varicocelectomy may have the potential to improve sexual function along with serum testosterone. In conclusion, indications for microsurgical varicocelectomy may be extended by the concomitant right and left clinical varicocele and sexual dysfunction with varicocele.

  • Human varicella zoster virus is not present in the semen of a man affected
           by chickenpox during the in vitro fertilisation of his wife
    • Authors: D. Y. L. Chan; K. K. W. Lam, E. Y. L. Lau, W. S. B. Yeung, E. H. Y. Ng
      Abstract: Human varicella zoster virus (VZV) is a member of the herpes virus family and affects humans only. Information about the presence of the virus in the semen samples of men affected by chickenpox is rather limited in the literature. Here, we reported a husband was affected by VZV during in vitro fertilisation treatment of his wife treated in our centre. The semen sample was checked for the presence of VZV by the PCR technique. The PCR result found no detectable viral DNA in the semen sample. The semen sample was then used for conventional IVF insemination and subsequently a healthy baby boy was born. This single case report suggests that the semen sample of men affected by chickenpox may be safe to use for assisted reproduction methods during the VZV infective period.

  • Trehalose sustains a higher post-thaw sperm motility than sucrose in
           vitrified human sperm
    • Authors: M. Schulz; J. Risopatrón, G. Matus, E. Pineda, C. Rojas, V. Isachenko, E. Isachenko, R. Sánchez
      Abstract: One of the cryopreservation methods that best preserves sperm function is vitrification. However, comparative studies have not been performed to evaluate the effect of nonpermeable cryoprotectors on sperm function for prolonged periods of time post-devitrification. These times are necessary, especially in in vitro fertilisation and intrauterine insemination, for gamete interaction and then fertilisation to occur, while maintaining motility to arrive at the fertilisation site. In this study, sucrose (.25 m) and trehalose (.1 and .05 m) were compared in essential parameters like motility and plasma membrane integrity for 12 hr. Post-devitrification sperm motility using .1 m trehalose was 68.9%, higher than that obtained with .05 m trehalose (59.9%, p

  • Effects of taking tadalafil 5 mg once daily on erectile function and
           total testosterone levels in patients with metabolic syndrome
    • Authors: L. Ozcan; E. C. Polat, R. Kocaaslan, E. Onen, A. Otunctemur, E. Ozbek
      Abstract: We aimed to evaluate the efficacy of tadalafil 5 mg once-daily treatment on testosterone levels in patients with erectile dysfunction (ED) accompanied by the metabolic syndrome. A total of 40 men with metabolic syndrome were evaluated for ED in this study. All the patients received 5 mg tadalafil once a day for 3 months. Erectile function was assessed using the five-item version of the International Index of Erectile Function (IIEF) questionnaire. Serum testosterone, follicle-stimulating hormone and luteinising hormone levels were also evaluated, and blood samples were taken between 08.00 and 10.00 in the fasting state. All participants have three or more criteria of metabolic syndrome. At the end of 3 months, mean testosterone values and IIEF scores showed an improvement from baseline values (from 3.6 ± 0.5 to 5.2 ± 0.3, from 11.3 ± 1.9 to 19 ± 0.8 respectively). After the treatment, serum LH levels were decreased (from 5.6 ± 0.6 to 4.6 ± 0.5). There was significantly difference in terms of baseline testosterone and luteinising hormone values and IIEF scores (p

  • Effects of various cryoprotectants on the quality of frozen–thawed
           immature bovine (Qinchuan cattle) calf testicular tissue
    • Authors: X.-G. Zhang; H. Li, J.-H. Hu
      Abstract: To investigate the effects of different concentrations of various cryoprotectants (CPs) on the cell viability as well as expression of spermatogenesis-related genes, such as CREM, Stra8 and HSP70-2 in frozen–thawed bovine calf testicular tissue, immature bovine (Qinchuan cattle) calf testicular tissue was collected and cryopreserved in the cryomedia containing different concentrations (5%, 10%, 15% and 20%) of the following three CPs: glycerol, ethylene glycol (EG) and dimethyl sulphoxide (DMSO) respectively. After 1 month cryopreservation in liquid nitrogen, cell viability was evaluated using Trypan blue exclusion under a bright-field microscope. The mRNA expression of the three genes was also evaluated using qRT-PCR. The results indicated that different concentrations of glycerol, EG and DMSO in cryomedia during cryopreservation could protect bovine calf testicular tissue in various ways to avoid freezing or cryopreservation-induced expression changes in spermatogenesis-related genes. The highest cell viability and the three spermatogenesis-related genes (CREM, Stra8 and HSP70-2) expression level came from the cryomedia containing glycerol, EG and DMSO at 10% concentration respectively (p

  • Improvement in erectile function in a rat model of high cholesterol
           diet-induced atherosclerosis by atorvastatin in a manner that is
           independent of its lipid-lowering property
    • Authors: Z. Zhang; L. Tang, W. Yu, Y. Chen, Y.-t. Dai
      Abstract: The purpose of the present study is to explore the effects of a lipid-lowering drug atorvastatin, a three-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitor, in the treatment of erectile dysfunction (ED) in a rat model of atherosclerosis (AS) and the possible mechanisms underneath. A high-cholesterol diet was administrated to Sprague-Dawley rats in an attempt to induce an ASED model, which was later confirmed by abdominal aorta histopathology and erectile function evaluation. ASED rats were further assigned to non-treatment group, atorvastatin low-dose treatment group (5 mg kg−1 day−1), high-dose group (10 mg kg−1 day−1) and sildenafil (1.5 mg kg−1 day−1) treatment group. Lipid profile, erectile function, oxidative stress biochemical markers, endothelial nitric oxide synthase (eNOS) and extracellular superoxide dismutase (SODEX) mRNA expression were evaluated after 8-week treatment duration. Erectile function was impaired in AS rat model, which was preserved in atorvastatin and sildenafil intervention groups. The oxidative stress biochemical markers were attenuated, while eNOS and SODEX mRNA expression were restored in atorvastatin and sildenafil groups, which were found to be involved in ED pathogenesis. However, the lipid profile remained unaltered in the treatment group, and it was elevated in ASED rats. This kind of lipid-lowering agent, or atorvastatin, has the utilisation potential in ASED treatment, even before lipid profiles altered. This effect on erectile function preservation of atorvastatin was attributed to its preservation of endothelial function, possibly through amelioration of oxidative stress and improvement in eNOS expression.

  • Review on arsenic-induced toxicity in male reproductive system and its
           amelioration
    • Authors: M. Zubair; M. Ahmad, Z. I. Qureshi
      Abstract: Arsenic is an environmental toxicant which causes mutagenic, teratogenic and carcinogenic defects. It is used as herbicide, fungicide and rodenticide and results in contamination of air, soil and water. Arsenic is also produced through burning of coal industries. The sludge of factories contaminates the fodder and drinking source of water of human and livestock. Arsenic binds thiol groups in tissue proteins and impairs the function of the proteins. This metal affects the mitochondrial enzymes and interrupts the production of energy. Oxidative stress and the generation of reactive oxygen species could also be a consequence of arsenic exposure. High arsenic level may suppress the sensitivity of gonadotroph cells to GnRH as well as gonadotropin secretion by elevating plasma levels of glucocorticoids. These ultimately lead to the development of gonad toxicity in animals and cause the reduction in sperm number, sperm viability and motility. Massive degeneration of germ cells and alterations in the level of LH, FSH and testosterone are also reported. The objective of this review was to find out the effects of arsenic-induced toxicity on male reproductive system in animals and its amelioration.

  • Metabonomic analysis of fatty acids in seminal plasma between healthy and
           asthenozoospermic men based on gas chromatography mass spectrometry
    • Authors: B. Tang; X. Shang, H. Qi, J. Li, B. Ma, G. An, Q. Zhang
      Abstract: The mechanism of asthenozoospermia remains unclear. The knowledge of the metabolism of fatty acids in seminal plasma is important and meaningful for the pathological study of asthenozoospermia. We present an optimised assay of extraction and derivatisation followed by GC/MS to analyse metabolites, especially fatty acids, in seminal plasma from healthy and asthenozoospermic men. Eighty-nine peaks including 17 kinds of fatty acids were analysed and identified in the chromatogram. The GC/MS data were analysed using t test, fold change and partial least squares discriminant analysis to explore the potential biomarkers of asthenozoospermia. Seven metabolites in asthenozoospermic group were found to be significantly different from those in the normal group (with p 1.2 and variable importance for projection>1). Of which, high levels of oleic acid and palmitic acid in seminal plasma from asthenozoospermic men may indicate a membrane metabolism disorder in spermatozoa and the lack of valine in the asthenozoospermic group may contribute to poor sperm motility. The results may facilitate the understanding of the role of fatty acids and amino acids in asthenozoospermia and provide solid foundation for further pathological study of asthenozoospermia.

  • Use of the fluorescent dye tetramethylrhodamine methyl ester perchlorate
           for mitochondrial membrane potential assessment in human spermatozoa
    • Authors: P. Uribe; J. V. Villegas, R. Boguen, F. Treulen, R. Sánchez, P. Mallmann, V. Isachenko, G. Rahimi, E. Isachenko
      Abstract: Mitochondrial membrane potential (ΔΨm) is an indicator of sperm quality and its evaluation complements the standard semen analysis. The fluorescent dye JC-1 has been widely used to assess sperm ΔΨm; however, some problems have been detected under certain experimental conditions. Another fluorescent compound, tetramethylrhodamine methyl ester perchlorate (TMRM), has been used in somatic cells and bovine spermatozoa but not in human spermatozoa. TMRM accumulates in hyperpolarised mitochondria and the fluorescence intensity of this compound correlates with ΔΨm. Thus, the aim of this study was to evaluate and validate the usefulness of the fluorescent dye TMRM for measuring sperm ΔΨm. The results showed that TMRM accurately detects sperm populations displaying either high or low ΔΨm. Moreover, TMRM was able to measure sperm ΔΨm under the experimental conditions in which JC-1 had previously presented difficulties. Differences in ΔΨm according to sperm and semen quality were properly detected and a positive correlation between ΔΨm and conventional semen parameters was observed. Finally, a positive correlation was found between the ΔΨm measurement by TMRM and by the widely used JC-1. In conclusion, TMRM is a simple, time-effective method, easy to set in laboratories equipped with flow cytometry technology, and can accurately detect changes in ΔΨm with efficiency comparable to JC-1 without its limitations.
