Mode of action of centchroman at vaginal and ovarian level in immature rats.

Centchroman studied at various doses did not cause ovulation in immature rats as judged by morphological, histological and biochemical parameters whereas, 20 mg/kh dose caused early opening of vagina and cornification of the vaginal epithelial cells. However, no ovulation was detected by this regimen. No stimulatory effect was observed in the glycogen and cholesterol content in the ovaries of Centchroman treated rats. The effects on vagina persisted even in ovariectomised immature rats administered with Centchroman. The mode of various doses of Centchroman in immature rats as judged morphologically, histologically and biochemically has been discussed.
