Dehydroepiandrosterone (DHEA) and its sulfate metabolite DHEAS are the majo
r androgens secreted by the human adrenal gland. The specific control of th
ese hormones remains unclear. While ACTH is a potent stimulator of DHEA sec
retion, other factors both systemic and local have been involved in adrenal
androgen control. Here we review the extra and intra-adrenal regulation of
DHEA and propose a hypothetical model for adrenal senescence.
