DHEA

Dehydroepiandrosterone (DHEA) is an androgen synthesized and secreted primarily by the adrenal cortex. It has a short half-life and its concentration in the blood is 300-fold lower than that of DHEA sulfate. There is a circadian rhythm of secretion with highest concentrations in the morning. DHEA is a sensitive indicator of adrenal androgenic secretion and it is measured in the investigation of hyperandrogenism in women and in the evaluation of abnormalities of puberty in children.
