11-Beta-hydroxyandrostenedione (4-Androsten-11β-ol-3,17-dione) 是一种主要存在于肾上腺的类固醇 (11β-羟化酶存在于肾上腺组织，但在卵巢组织中不存在)。11-Beta-hydroxyandrostenedione 是一种 11β-羟基类固醇脱氢酶 (11βHSD) 同工酶抑制剂。随着 4-androstenedione 的增加，测量血浆 11-Beta-hydroxyandrostenedione 可以区分高雄激素血症的肾上腺或卵巢起源。

Background:

11-Beta-hydroxyandrostenedione (4-Androsten-11β-ol-3,17-dione) is a steroid mainly found in the the adrenal origin (11β-hydroxylase is present in adrenal tissue, but absent in ovarian tissue). 11-Beta-hydroxyandrostenedione is a 11β-hydroxysteroid dehydrogenase (11βHSD) isozymes inhibitor. As 4-androstenedione increases, measuring plasma 11-Beta-hydroxyandrostenedione can distinguish the adrenal or ovarian origin of hyperandrogenism[1][2].
