11-Ketodihydrotestosterone
11-Ketodihydrotestosterone, also known as 5α-androstan-17β-ol-3,11-dione, is an endogenous, naturally occurring steroid and androgen prohormone that is produced primarily, if not exclusively, in the adrenal glands. It is closely related to 11β-hydroxyandrostenedione, adrenosterone, and 11-ketotestosterone, which are also produced in the adrenal glands.
