Abstract

The effect of chloroform crude extract from Dioscores hispida Dennst. On some reproductive parameters of adult male laboratory rats was evaluated. Treatment level concentrations of 120, 60 and 30 mg/kg bw were prepared and administered to the rats through stomach intubation using a ball point needle fitted to a syringe. The dose levels used approximated 10% of the 1.050 value established on the material. Results showed that crude extract caused significant decrease on sperm motility. Significant influence on sperm morphology was also observed. In body weight gain. Significant differences on the effect of different treatment levels was observed during the first, fourth, sixth and ninth weeks of treatment. However, no significant decrease on sperm count and organ weights was observed. Histological sections of testes under the low, moderate and high doses showed apparent accumulations of excess fluid along the interstitum. In addition, testes of mature albino rats under the high dose treatment exhibited significant degeneration of some seminiferous tubules.
