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[1]. 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 sensitivity of the pituitary to gonadotrophin-releasing hormone (GnRH) and that of the testis to gonadotrophin (GTH) was monitored in African catfish in vivo at different stages of pubertal development (20, 21, 24, 31, 39, 42 and 49 weeks of

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

In a longitudinal study of 82 children we found a gradual rise in median plasma concentrations of 11 beta-hydroxyandrostenedione (11 beta-OH-A4) from 2.5 to 6.4 nmol/l during childhood which was similar in both sexes. This could reflect changes in adrenal

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

To reevaluate the clinical significance of elevations of adrenal androgens in polycystic ovary syndrome (PCOS). Thirty women with PCOS and ten ovulatory controls were evaluated. Serum dehydroepiandrosterone (DHEA) sulfate and 11 beta-hydroxyandrostenedione were measured before and after 3 and 6
