Abstract: An improvement in a method of treating benign gynecological disorders is described. In the method, treatment of a benign gynecological disorder with a composition comprised of a gonadotropin releasing hormone (GnRH) compound and an estrogenic compound, and optionally, an androgenic compound, is extended to premenopausal women who are not receiving an exogenously supplied progestin on a regular or periodic basis. Treatment in accord with the invention does not increase significantly the risk of endometrial hyperplasia. The method is also suitable for contraception.

Abstract: A nasal spray formulation for use in female contraception or in the treatment of benign gynecological disorders is described. The nasal preparation is comprised of a GnRH compound and an estrogenic compound in the form of a water-soluble complex with a water-soluble cyclodextrin. The preparation effectively suppresses ovarian estrogen and progesterone production, and prevents signs and symptoms of estrogen deficiency, without a significant increase in the risk of endometrial hyperplasia.
