Compositions and methods for use in preventing conception or treating benign gynecological disorders, wherein an effective amount of an antiprogestational agent [e.g., progesterone (progestin, progestogen, gestagen) antagonist or progesterone synthesis inhibitor] administered over a first period of time is combined with an effective amount of a progestogen for a second period of time. The antiprogestational agent is selected from single agents or mixtures thereof. The progestogen is selected from single agents or mixtures of natural or synthetic progestogens. The formulations are effective as contraceptive agents and for treatment of benign gynecological disorders including uterine fibroids, premenstrual syndrome, dysfunctional uterine bleeding, polycystic ovarian syndrome and endometriosis. |
