Antifertility investigations on the crude chloroform extract of Carica papaya Linn. seeds in male albino rats.
Crude chloroform extract of C. papaya seeds (5 mg/animal/day, po, for 20, 40 and 60 days) was investigated for contraceptive efficacy and related side effects in male albino rats. The crude extract reduced fertility to zero per cent by 40 to 60 days of treatment. Suppression of cauda epididymal sperm motility was the most pronounced effect of the drug administration. Scanning electron microscopic observations revealed treatment induced abnormalities in sperms. Cauda epididymal and testicular sperm counts decreased following treatment. Clinical parameters did not show any alterations. Results suggest that the contraceptive effects of chloroform extract of papaya seeds are mainly post-testicular in nature without influencing toxicological profile and libido of the animals.
