Segesterone Acetate has been used to study the: comparison of androgenic and estrogenic properties of progestins used in contraception and hormone therapy; impact on hepatic estrogen-sensitive proteins by 1-yr contraceptive vaginal ring delivering Nestorone and ethinyl estradiol.

ChEBI: Elcometrine is a corticosteroid hormone.

Elcometrine is a member of the 19-norprogesterone class of pr ogestins. when administered subcuta neously (implant), intravaginally (vaginal ring), or transdermally, elcometrine is an exceptionally potent progestin. It is 100-fold more potent when administered subcutaneously than when delivered orally. Its oral bioavaiability is only 10%，with a half life of just 1 to 2 hours because of rapid metabolism. The C16 methylene functionality substantially increases its affinity for the progesterone receptor.

Because of its antiestrogenic action, elcometrine also can be administered transdermally along with estradiol as a treatment for menopausal symptoms .
