Dehydroepiandrosterone Sulfate (DHEA-S)
Androgens and Male Reproductive Endocrinology
Dehydroepiandrosterone Sulfate (DHEA-S)
DHEA-S is a sulfated adrenal androgen precursor with different circulating handling from unconjugated DHEA. Sulfatase and sulfotransferase activity contribute to local interconversion.
Production, transport and local action
Androgen action depends on central gonadotropin drive, gonadal production, binding proteins and tissue-specific metabolism. Conversion to DHT or estradiol changes the local signal. Receptor expression and cofactors determine how exposure becomes a response in each organ.
A distinction that matters
It generally provides a more stable circulating precursor measure than a short-lived secretory pulse. A high or low value requires age-appropriate and clinical interpretation rather than a performance-oriented target.
Interpreting androgen status
Symptoms, repeated appropriately timed measurements and relevant LH, FSH and SHBG results help distinguish endocrine patterns. A transient exercise-associated change does not predict hypertrophy. Exogenous androgen exposure can suppress endogenous regulation and fertility despite high circulating concentrations.
