Preoperative and postoperative sperm parameter values from infertile men with varicocele were analyzed by computer-aided sperm analysis (CASA) to assess if sperm characteristics improved after varicocelectomy. Semen samples of men with proven fertility (n = 38) and men with varicocele-related infertility (n = 61) were also analyzed. Conventional semen analysis was performed according to WHO (20...

This study investigated the correlation between sperm motion parameters obtained by a computer-assisted semen analyzer and levels of reactive oxygen species in unwashed semen. In total, 847 patients, except for azoospermic patients were investigated. At the time of each patient's first consultation, semen parameters were measured using SMAS™ or CellSoft 3000™, and production of reactive oxygen ...

BACKGROUND There is clinical evidence to show that sperm DNA damage could be a marker of sperm quality and extensive data exist on the relationship between DNA damage and male fertility status. Detecting such damage in sperm could provide new elements besides semen parameters in diagnosing male infertility. We aimed to assess sperm DNA fragmentation and oxidation and to study the association be...

background:   objective: the aim of this study was to investigate the harmful effects of sodium arsenite on sperm parameters and the antioxidant effects of vit.e on sperm anomalies in sodium arsenite treated rats.   materials and methods: adult male rats were divided into 4 groups: control, sodium arsenite (8 mg/kg/day), vit.e (100 mg/kg/day) and sodium arsenite+vit.e. oral treatments were perf...

Objective(s): Nicotine as a toxic substance leads to impairment of the reproductive system function. The aim of this study was to evaluate effects of melatonin on testicular alterations, sperm nuclear integrity, and epididymal sperm parameters in mice treated with nicotine.Materials and Methods: Male mice were divided into four groups. Group A received the vehicle, group B received nicotine 0.1...
