title: Histological and biochemical changes in the female genital tract of rats and mice after methallibure treatment.
abstract: Methallibure administration caused reduction of gonadal weights in female rats and mice indicative of suppression of pituitary gonadotrophins. In the ovaries of the methallibure treated females, there was a great atresia of the follicles and of the corpora lutea. Methalbure caused atrophic changes in the endometrial lining of the vagina. Uterine horns became thin after methallibure treatment. A significant decrease in protein, RNA and sialic acid concentration in uterus and vagina was observed following methallibure treatment. Uterus of treated animals showed decreased glycogen contents. Histological and biochemical changes in the female genital tract of rats and mice suggested that the drug caused antifertility effect due to its possible antiestrogenic action.
