  • Method of totally suppressing ovarian follicular development
    Patent number: 4522831
    Abstract: Ovarian follicular development and related hormonal secretions are totally suppressed for periods of several months or longer by a single intramuscular injection of anordrin administered during menstruation given preferably on the first day of menstrual bleeding. The amount of anordrin administered is in the range of 2 to 10 mg per kg of body weight, and is effective to produce the suppression without administration of additional anordrin by any route. Suppression of progesterone and estradiol secretions is of therapeutic value in the treatment of endometrosis, breast cancer, and other conditions aggravated by ovarian hormones.
