Infobox references
Androstanedione , also known as 5α-androstanedione or as 5α-androstane-3,17-dione , is a naturally occurring androstane (5α-androstane) steroid and an endogenous metabolite of androgens like testosterone , dihydrotestosterone (DHT), dehydroepiandrosterone (DHEA), and androstenedione .[ 1] It is the C5 epimer of etiocholanedione (5β-androstanedione).[ 1] Androstanedione is formed from androstenedione by 5α-reductase and from DHT by 17β-hydroxysteroid dehydrogenase.[ 2] [ 3] It has some androgenic activity.[ 4]
In female genital skin, the conversion of androstenedione into DHT through 5α-androstanedione appears to be more important than the direct conversion of testosterone into DHT.[ 5]
