Preparation of Androstenediol: It is derived from dehydroepiandrosterone by the reduction of the 17-keto group (17-hydroxysteroid dehydrogenases), is converted to testosterone by the oxidation of the 3-beta hydroxyl group to a 3-keto group (3-hydroxysteroid dehydrogenases).

Uses of Androstenediol: It is used as intermediate of steroid hormone and acyeterion. Its potential use as a radiation countermeasure was introduced by the Armed Forces Radiobiology Research Institute (AFRRI) and subsequently studied by AFRRI and Hollis-Eden Pharmaceuticals under the tradename Neumune for the treatment of acute radiation syndrome.
