How does Dhea affect testosterone?

DHEA (Dehydroepiandrosterone), mainly produced by the adrenals, acts as a global promoter of sex steroid hormones, including testosterone and estrogen. The specific increase of either hormone due to DHEA supplementation depends on individual factors such as initial hormone levels and the presence of aromatase, an enzyme converting androgens into estrogens. For example, individuals with higher levels of aromatase may experience more conversion of DHEA into estrogen rather than testosterone. Consequently, the effects of DHEA on hormone levels vary significantly among individuals, depending on their unique biological context 1.
