DHEA is the primary adrenal androgen and is an important precursor in the biosynthesis of testosterone and estrogens. Nevertheless, circulating DHEA does not appear to be a major precursor of testosterone in cases of androgen excess. It has also been shown that FREE DHEA may be derived in large part from the hydrolysis of circulating DHEA-sulfate, the most abundant adrenal steroid known. Free DHEA levels are often used in conjunction with plasma testosterone, androstenedione, and DHEA-sulfate.
