11β-Hydroxyandrostenedione (11β-OHA4), also known as 11β-hydroxyandrost-4-ene-3,17-dione, is an endogenous, naturally occurring steroid and androgen prohormone that is produced primarily, if not exclusively, in the adrenal glands.^[1] It is closely related to adrenosterone (11-ketoandrostenedione; 11-KA4), 11-ketotestosterone (11-KT), and 11-ketodihydrotestosterone (11-KDHT), which are also produced in the adrenal glands.^[1]

It can be used as a biomarker for guiding primary aldosteronism subtyping in adrenal vein sampling where blood samples are taken from both adrenal glands to compare the amount of hormone made by each gland.^[2]
