Caesalpinia bonduc (L.) Roxb. are variously used in traditional health system. Present study was carried out to test antispermatogenic effect of Caesalpinia bonduc (L.) Roxb. seeds on male albino rats. Aqueous extract of seeds of C. bonduc administered orally for 21 days resulted in decreased sperm count in male albino rats. It significantly reduced sperm density and exhibited 9.06%, 25.29 % and 39.79 % average increase in antispermatogenic activity with treatment at concentrations of 50, 100 and 150 mg/kg respectively. Results suggest that the C. bonduc seeds can be used to develop a safe and effective male contraceptive
