PRODUCT INTRODUCTION
description
Ethisterone is a 17beta-hydroxy steroid that is testosterone in which the 17beta hydrogen is replaced by an ethynyl group. Ethisterone was the first orally active progestin and is a metabolite of danazol. It has a role as a progestin and a drug metabolite. It is a 17beta-hydroxy steroid, a 3-oxo-Delta(4) steroid, a terminal acetylenic compound and a tertiary alcohol. It is functionally related to a testosterone.
