Etiocholanedione, also known as 5β-androstanedione or as etiocholane-3,17-dione, is a naturally occurring etiocholane (5β-androstane) steroid and an endogenous metabolite of androgens like testosterone, dihydrotestosterone, dehydroepiandrosterone (DHEA), and androstenedione.^[1] It is the C5 epimer of androstanedione (5α-androstanedione).^[1] Although devoid of androgenic activity like other 5β-reduced steroids, etiocholanedione has some biological activity of its own.^[2]^[3] The compound has been found to possess potent haematopoietic effects in a variety of models.^[2] In addition, it has been found to promote weight loss in animals and in a double-blind, placebo-controlled clinical study in humans conducted in 1993.^[3]^[4] These effects are said to be similar to those of DHEA.^[5] Unlike DHEA however, etiocholanedione cannot be metabolized further into steroid hormones like androgens and estrogens.^[5]
