Abstract

|
The study was undertaken to evaluate the anti-spermatogenic efficacy of ethanol extract of stem bark of Dalbergia sissoo Roxb. For the in vitro study, semen samples were obtained from 15 healthy fertile men aged 25?35 years. Sperm motility was examined by the Sander-Cramer method. A dose-dependent and time-dependent effect of ethanol extract on sperm motility and sperm viability were observed. Various concentrations affected the motility of sperm. Ethanol extract at a concentration of 20 mg/mL caused complete immobilization within 3 minutes. Sperm viability and hypo-osmotic swelling was significantly reduced at this concentration. The in vivo studies were carried out on Swiss male albino mice. Ethanol extract at a dose of 200 mg/kg body weight resulted in a significant decrease (p<0.001) in weight of the testis and epididymis. A significant decrease (p<0.01) in sperm motility and sperm count in the epididymis were observed. Histological changes in the epididymis and testis were also investigated.
