11-Beta-hydroxyandrostenedione 是主要存在于肾上腺的类固醇，也是 11β-羟基类固醇脱氢酶同工酶抑制剂。随着 4-androstenedione 的提高，通过测量血浆中的11-Beta-hydroxyandrostenedione，能够区分高雄激素血症的肾上腺或卵巢起源。

11-Beta-hydroxyandrostenedione is a steroid mainly found in the adrenal origin (11β-hydroxylase is present in adrenal tissue, but absent in ovarian tissue), which is a 11β-hydroxysteroid dehydrogenase isozymes inhibitor. Measuring plasma 11-Beta-hydroxyandrostenedione can distinguish the adrenal or ovarian origin of hyperandrogenism with 4-androstenedione increases.

21-deoxycortisol (21dF) and 21-deoxycortisone (21dE) are assayed within the LNCaP cell line to establish that this conversion is catalyzed by the lyase activity of CYP17A1. After the transfection of CYP17A1, 11-Beta-hydroxyandrostenedione (11OHA4)-pathway metabolites increase, 21dF, and 21dE are in fact metabolized to 11-Beta-hydroxyandrostenedione and 11-ketoprogesterone (11KP4) by CYP17A1, respectively [2].

In 21-hydroxylase deficiency, Cushing's syndrome, and hyperandrogenism of adrenal origin, the plasma concentration of 11-Beta-hydroxyandrostenedione (11beta-hydroxy-4-androstene-3,17-dione) is very high. In congenital 11-hydroxylase deficiency and adrenal insufficiency, the plasma concentration of 11-Beta-hydroxyandrostenedione (11beta-hydroxy-4-androstene-3,17-dione) is very low. Thus, when plasma 4-androstenedione is elevated, it is useful to measure the plasma 11-Beta-hydroxyandrostenedione level in order to determine the adrenal or ovarian origin of the hyperandrogenism [1].
