11β-Hydroxyandrostenedione是一种内源性、天然存在的?类固醇和雄激素原，主要（如果不是完全）在肾上腺中产生。它与肾上腺产生的肾上腺素(11-ketoandrostenedione; 11-KA4)、11-ketotestosterone?(11-KT) 和11-ketodihydrotestosterone?(11-KDHT)密切相关。可用作指导肾上腺静脉取样中原发性醛固酮增多症亚型的生物标志物，其中从两个肾上腺采集血样以比较每个腺体产生的激素量。
4-Androsten-11β-ol-3,17-dione (11OHA4) is a steroid that has been found in isolated human female adrenal veins.1 It is non-androgenic, however, it is metabolized to the androgenic 5α-reduced C19 steroids 11-hydroxy-5α-androstanedione, 11-keto-5α-androstanedione, 11-hydroxydihydrotestosterone, and 11-ketodihydrotestosterone in LNCaP cells.
