Biochem/physiol Actions

11β-Hydroxy-4-androstene-3,17-dione is a naturally occurring steroid that is primarily, if not strictly, produced in adrenal tissue. In diseases such as Cushing′s syndrome, adrenal-originated hyperandrogenism, and congenital adrenal hyperplasia, plasma 11β levels are very high. Plasma 11β concentration is very low in congenital 11-hydroxylase deficiency and adrenal insufficiency.

The plasma concentration of 11beta-hydroxy-4-androstene-3,17-dione (11beta) is very high in 21-hydroxylase deficiency, Cushing's syndrome, and hyperandrogenism of adrenal origin, and very low in congenital 11-hydroxylase deficiency and adrenal insufficiency. Thus, when plasma 4-androstenedione is elevated, it is useful to measure

To determine whether the adrenal androgen 11 beta-hydroxyandrostenedione is a more sensitive and specific marker than dehydroepiandrosterone sulfate, we compared these serum androgens in 81 women with anovulatory hyperandrogenism before treatment, after corticotropin and corticotropin-releasing-factor stimulation, and after short- and
