Clinical value of adrenal androgen measurement in the diagnosis of delayed puberty

Abstract

Serum levels of the adrenal androgens dehydroepiandrosterone (DHA), dehydroepiandrosterone sulphate (DHAS), and androstenedione (A) were measured in 90 males (age range 14 1/2--26 years) presenting with delayed puberty to an adult endocrine clinic over a period of 3 years. The results show that adrenal androgen levels are significantly lower (p less than 0.0005) in subjects with growth-hormone (GH) deficiency than in patients with simple and constitutional delayed puberty and other, less common, conditions. By contrast, subjects with hypogonadotropic hypogonadism had significantly raised values (p less than 0.0005). On initial presentation DHA and DHAS measurements correctly identified all GH-deficient subjects and in addition DHAS measurements identified 89% of subjects with hypogonadotropic hypogonadism. It is suggested that measurement of serum levels of DHA and DHAS may assist greatly in the early diagnosis of conditions causing delayed puberty, and thus may prevent unnecessary delay in treatment.
