RESUMEN
PURPOSE: Obstructive sleep apnea is characterized by repetitive cessation of breathing during sleep. It affects different aspects of sexuality. We aimed to assess male sexual function & risk factors in obstructive sleep apnea patients. METHODS: This case control study included 2 groups, 45 healthy volunteers as control group and 45 patients with confirmed diagnosis of obstructive sleep apnea. All the participants were subjected to measurement of Body Mass Index, Full night polysomnography (only for patients group) and serum total testosterone, FSH and LH. The International Index of Erectile Function-5 and Hamilton Depression Scale questionnaires were filed out for all participants. RESULTS: The mean scores for all sexual domains were significantly lower among the patients group compared to the control group (p<0.01). The Hamilton score was significantly higher among the patients group compared to the control group (p<0.0001). The mean levels of Testosterone and LH were significantly lower among the patients group compared to controls (p<0.0001), There were significant correlations between disease severity and age (r=0.48, p=0.001), Body mass index (r=0.48, p=0.001), Hamilton score (r=0.34, p=0.014) International Index of Erectile Function 5 domain score (r= -0.29, p=0.045)Testosterone level (r= -0.29, p=0.046) and LH levels (r= -0.104, p=0.049). CONCLUSION: We found that all domains of sexual function have been affected in patients group than controls. Their score was inversely related to the disease severity; which in turn has a complex interaction with other factors like age, obesity, hormones and psychological status. So when evaluating those patients, sexual dysfunction should be considered and assessed along with these factors.

Thyroid hormones play essential roles in spermatogenesis, but their effects on infertile males remain poorly understood. This study aimed to evaluate the impact of combining carbimazole (CBZ) with vitamin E (VE) on testicular injury induced by experimental hyperthyroidism in adult albino rats, focusing on oxidative, inflammatory, and apoptotic pathways. In this experimental study, 64 adult male albino Wistar rats were divided into eight groups: Group I (control-untreated), Group II (CBZ-control), Group III (VE-control), Group IV (CBZ + VE-control), Group V (levothyroxine-induced testicular injury), Group VI (levothyroxine + CBZ-treated), Group VII (levothyroxine + VE-treated), and Group VIII (levothyroxine + CBZ + VE-treated). The study was conducted in the Faculty of Medicine, Suez Canal University (Ismailia, Egypt). After cervical decapitation, both testes and epididymis were examined histopathologically and immunohistochemically. Significant differences were observed among groups concerning malondialdehyde (MDA), glutathione (GSH), superoxide dismutase (SOD), and catalase (CAT; all P < 0.001). Polymerase chain reaction analysis showed significant differences in tumor necrosis factor-α (TNF- α ), interleukin-10 (IL-10), Bcl-2-associated X protein (BAX), B-cell lymphoma 2 protein (Bcl2), p53, Caspase-3, Caspase-8, Caspase-9, and nuclear factor-kappa B (NF- κ B) mRNA levels (all P < 0.001). Hyperthyroid group treated with CBZ alone (Group VI) exhibited testicular side effects, affecting seminiferous tubules and spermatogenesis. However, the Group VIII showed improved spermatogenesis and a decrease in testicular side effects. The addition of VE to the treatment of hyperthyroid rats with CBZ reduced testicular side effects and seminiferous tubular affection when potentially improving spermatogenesis. Further research is needed to elucidate the underlying mechanisms fully.

OBJECTIVES: The present study evaluated the correlation between the concentrations of polychlorinated biphenyls (PCBs) and pesticides in the follicular fluid (FF) obtained during intracytoplasmic sperm injection (ICSI) with the ovarian response, endometrial thickness, and embryological and clinical outcomes. DESIGN: Cross-sectional observational study. MATERIALS AND METHODS: Women aged 20 to 38 years (300 infertile couples) presenting to a university-affiliated fertility center were approached to participate in the study. Only 150 couples that underwent ICSI for male factor infertility agreed to participate, and 94 of them had retrieved enough FF samples suitable for laboratory testing. The FF sample was obtained, centrifuged, and stored in liquid nitrogen. Two organochlorine pesticides (OCPs), Lindane and DDT;three organophosphates (OPs);chlorpyrifos;Diazinon; malathion; one Chloroacetanilide (Pretilachlor);two pyrethroids(Bioallethrin and ß-cyfluthrin); and the concentrations of four PCBs, 28, 52, 138, 180, were estimated in the obtained FF samples by using gas chromatography/mass spectrometry. SPSS statistical analysis program (version 17) was used for analysis. Multiple regression analysis was used to correlate the PCBs and pesticides with ICSI outcomes. RESULTS: There were significant negative correlations between FF concentrations of the eight examined pesticides and the four PCBs on the endometrial thickness. However, Pretilachlor, chlorpyrifos, ß-cyfluthrin, and Diazinon were the only toxic agents that negatively correlated with the number of the oocytes retrieved. Fertilization and early embryo cleavage rates were negatively correlated with Pretilachlor and ß-cyfluthrin. Moreover, high concentrations of Lindane,DDT, Diazinon,and chlorpyrifos were significantly associated lower implantation rate. PCB 28 and 180 concentration in the FF was associated with a lower number of retrieved oocytes and fertilization rate, respectively. The number of implanted embryos was negatively correlated with PCB 52 FF concentration. However, the clinical pregnancy rate did not reach the level of significance. CONCLUSION: Higher concentrations of any studied PCBs and pesticides are associated with thinner endometrial thickness. The higher the level of Pretilachlor, ß-cyfluthrin, PCB 28 and 180, the lower the retrieval, fertilization, and embryo cleavage rates. High PCB and pesticide concentrations in the FF adversely affected embryological ICSI outcomes. However, more data are needed to evaluate their effect on the clinical outcome.

Aim. This study aimed to assess seminal miRNA relationship with seminal apoptotic markers and oxidative stress (OS) in infertile men associated with varicocele (Vx). Methods. In all, 220 subjects were divided into the following groups: fertile normozoospermic men, fertile normozoospermic men with Vx, infertile oligoasthenoteratozoospermic (OAT) men without Vx, and infertile OAT men with Vx. They were subjected to history taking, clinical examination, and semen analysis. In their semen, the following were estimated: miRNA-122, miRNA-181a, and miRNA-34c5 using quantitative real-time PCR, apoptotic markers (BAX, BCL2) protein expression, and OS markers [malondialdehyde (MDA) and glutathione peroxidase (GPx)]. Results. The mean levels of seminal miRNA-122, miRNA-181a, and miRNA-34c5 were significantly reduced in infertile OAT men with Vx compared with other groups coupled with Vx grade and Vx bilaterality. Seminal miRNA-122, miRNA-181a, and miRNA-34c5 were positively correlated with sperm concentration, total sperm motility, sperm normal morphology, seminal GPx, and seminal BCL2 and negatively correlated with seminal MDA and seminal BAX. Conclusions. Seminal miRNA-122, miRNA-181a, and miRNA-34c5 are decreased in infertile OAT men with Vx associated with increased Vx grade and Vx bilaterality. In addition, they are positively correlated with sperm parameters and negatively correlated with OS, apoptotic markers.

OBJECTIVE: To assess Ropporin gene expression in the sperm of infertile asthenozoospermic men with varicocele (Vx) before and after repair. METHODS: This study included 24 infertile asthenozoospermic men with Vx. They were subjected to history taking, clinical examination, scrotal color Doppler, and semen analysis with sperm separation. Three months after varicocelectomy, they were subjected to postoperative color Doppler, semen analysis, and sperm semiquantitative Reverse Transcription-Polymerase Chain Reaction assay for Ropporin gene expression levels. RESULTS: Ropporin gene expression is significantly associated with different types of sperm motility, except for nonprogressive sperm motility. There was significant Ropporin gene overexpression postvaricocelectomy that was correlated with improved sperm count, sperm motility, and abnormal sperm morphology with decreased veins diameters. CONCLUSION: Ropporin gene expression is related to the sperm motility. Its abnormal expression in the sperm of asthenozoospermic men with Vx is associated with impaired sperm motility that is improved after varicocelectomy.
