Excessive apoptotic spermatozoon death is associated with male infertility. Leptin regulates apoptosis in several cell types. We prospectively investigated if seminal plasma leptin mediates spermatozoon apoptosis in 74 varicocele (VC) patients and 70 leucocytospermia patients. Spermatozoa from 40 normospermic men were used as controls. Routine semen analysis, spermatozoon apoptosis rate, seminal plasma...
Effects of acute tadalafil on sperm motility and acrosome reaction were investigated, both in vitro and in vivo. Twenty asthenozoospermic and 20 normozoospermic patients as control were randomly enrolled. For in vitro part, 0.5 ml tadalafil solutions with different concentrations were added (0.2, 0.1, 0.05 and 0.025 μg ml−1, respectively) into semen samples. In both groups, samples treated with 0...
