Epietiocholanolone


Epietiocholanolone, also known as 3β-hydroxy-5β-androstan-17-one or as etiocholan-3β-ol-17-one, is an etiocholane steroid as well as an inactive metabolite of testosterone that is formed in the liver. The metabolic pathway is testosterone to 5β-dihydrotestosterone, 5β-dihydrotestosterone to 3β,5β-androstanediol, and 3β,5β-androstanediol to epietiocholanolone. Epietiocholanolone can also be formed directly from 5β-androstanedione. It is glucuronidated and sulfated in the liver and excreted in urine.
