Oestrogenic activity of cyproterone acetate in female mice.
Effects of cyproterone acetate, a synthetic steroidal compound, on the reproductive organs of female mice have been investigated. This agent caused reduction of ovarian weights indicative of suppression of pituitary gonadotrophins. Oestrogenic nature of cyproterone acetate was investigated in intact and ovariectomized animals taking uterine weight, vaginal keratinization and other biochemical oestrogen sensitive parameters. Cyproterone acetate in ovariectomized animals induced vaginal keratinization increase in uterine weight and uterine protein, RNA, glycogen and sialic acid contents. These effects were parallel to the effects of oestradiol dipropionate in ovariectomized animals, thus indicating oestrogenic activity of the compound.
