Dehydroepiandrosterone sulfate (DHEA-S), also known as prasterone sulfate, is a naturally occurring, endogenous androstane steroid and neurosteroid and the 3β-sulfate ester of dehydroepiandrosterone (DHEA).

As the sodium salt, prasterone sodium sulfate, DHEA-S is used as a pharmaceutical drug in Japan in the treatment of insufficient cervical ripening and cervical dilation during childbirth.

Dehydroepiandrosterone sulfate is produced by the addition of a sulfate group, catalyzed by the sulfotransferase enzymes SULT1A1 and SULT1E1, which also produce estrone sulfate from estrone. DHEA sulfate can also be back-converted to DHEA through the action of steroid sulfatase.

In the zona reticularis layer of the adrenal cortex, DHEA-sulfate is generated by SULT2A1. This layer of the adrenal cortex is thought to be the primary source of serum DHEA-sulfate. DHEA sulfate levels decline as a person ages as the reticularis layer diminishes in size.

Dehydroepiandrosterone sulfate levels above 1890 micromol/L or 700-800 µg/dL are highly suggestive of adrenal dysfunction because DHEA-S is made exclusively by the adrenal glands. Presence of DHEA-S is therefore used to rule out ovarian or testicular origin of excess androgen.
