Edogestrone (INNTooltip International Nonproprietary Name, BANTooltip British Approved Name) (developmental code name PH-218), or edogesterone, also known as 17α-acetoxy-3,3-ethylenedioxy-6-methylpregn-5-en-20-one, is a steroidal progestin and antiandrogen of the 17α-hydroxyprogesterone group which was synthesized in 1964 but was never marketed.[1][2] Similarly to the structurally related steroid cyproterone acetate, edogestrone binds directly to the androgen receptor and antagonizes it, displacing androgens like testosterone from the receptor, though not as potently as cyproterone acetate.[3] The drug has also been found to suppress androgen production, likely via progesterone receptor activation-mediated antigonadotropic activity.[4]

Geller has also demonstrated significant decreases in plasma or urine testosterone glucuronide levels following the administration of three other anti-androgens. These include Delalutin, Chlormadinone acetate, and PH-218. It would appear that decreased androgen production is a property shared by all anti-androgens to date.
