Varicocele has a common association with male infertility, but its exact role is still debated. Apoptosis has been suggested as one of the mechanisms of varicocele-associated infertility. Granulysin is a molecule that plays a role in apoptosis with no previous study about its role in male infertility. This case-controlled study aimed to assess seminal plasma granulysin level in infertile patients with varicocele. This study involved 90 men that were allocated into fertile normozoospermic men (n = 20), infertile men without varicocele (n = 30) and infertile men with varicocele (n = 40)...

The number of white blood cell (WBC) in semen is an important indicator of genital tract inflammation in male infertility. The peroxidase assay is the recommended reference method for seminal WBC counting. However, it is time-consuming and may cause relatively heavy workload in daily routine. Meanwhile, the main component in the reagent of peroxidase test is harmful to human and the environment. In this study, we evaluated the analytical performance of the Sysmex UF-1000i that is a urine flow cytometer as a screening tool for genital tract infection in male infertility patients through the counting of seminal WBC...

Schwannomas rarely occur in seminal vesicles. Here, we report a schwannoma of the left seminal vesicle. A 55-year-old man presented no clinical symptoms, and a mass in the left region of the seminal vesicle was found incidentally in a medical examination. A computed tomography and magnetic resonance imaging of pelvic were obtained and revealed a 5.17 × 2.59 × 3.5 cm mass on the left seminal vesicle. Transrectal ultrasound-guided seminal biopsy revealed a diagnosis of seminal vesical schwannoma. Laparoscopic resection of the tumour was performed...

Tramadol, one of the most commonly abused drugs in Middle East, impacts spermatogenesis and disturbs reproductive hormones in animal studies. We aimed to investigate tramadol impact on sperm quality and on levels of testosterone, prolactin and gonadotropins, in tramadol abusers (n = 30) to age-matched control (n = 30). Abusers had significantly low percentages of sperm motility, normal forms and vitality compared with control (95% CI -40.7 to -19.3, -13.5 to -9.3 and -31.9 to -9.7 respectively). Hypoandrogenism (95% CI -4...

The health influence of air pollution has been an international public health concern. Increasing evidence has suggested that air pollution has been associated with decreased sperm quality. However, the underlying molecular mechanisms are still not fully elucidated. We aimed to verify whether gasoline exhaust leads to reproductive impairment by injuring spermatogonial stem cells and explore its underlying molecular mechanism. Twenty male Sprague-Dawley rats were randomly divided into two groups: the exposure group (n = 10) and the control group (n = 10)...

It has been assumed that β-endorphin, belonging to the family of opiodergic neuropeptides, might facilitate the inhibition of the male sexual response; however, its role in the control of the penile erectile tissue remains to be elucidated. This study aimed to evaluate in healthy men the course of β-endorphin in the systemic and cavernous blood through different stages of sexual arousal. Thirty-four (34) men were exposed to erotic stimuli to induce penile tumescence and rigidity. Blood was aspirated from the corpus cavernosum and a cubital vein during the penile conditions flaccidity, tumescence, rigidity and detumescence...
