What is the Origin of DHEA Replacement Therapy?

The practice originates from the identification of DHEA as the most abundant circulating adrenal steroid and the observation that its levels naturally decline significantly with age, a phenomenon often termed adrenopause. As DHEA serves as a precursor to androgens and estrogens, its therapeutic use emerged in the late 20th century to address age-related hormonal insufficiency. The 'Replacement Therapy' designation places it alongside other established endocrine treatments like thyroid or testosterone replacement.

What is the Mechanism of DHEA Replacement Therapy?

Administered DHEA is peripherally metabolized in target tissues, including fat, muscle, and skin, into potent sex steroids like testosterone and estradiol via local enzymatic action. This mechanism, known as intracrinology, allows DHEA to exert its biological effects where it is needed, bypassing the direct, high-dose stimulation of gonadal or adrenal pathways. The therapeutic effect is mediated by binding to androgen and estrogen receptors, influencing protein synthesis, lipid metabolism, and neuronal function.

DHEA Replacement Therapy

Meaning

DHEA Replacement Therapy is a specific clinical intervention involving the administration of exogenous dehydroepiandrosterone (DHEA) to restore circulating levels of this adrenal steroid precursor to a physiological range, typically in individuals with documented deficiency. This therapy aims to mitigate symptoms associated with DHEA decline, which may include fatigue, reduced libido, and altered mood or bone density. It is a nuanced approach, requiring precise dosing and ongoing biochemical monitoring to ensure safety and therapeutic efficacy without inducing supraphysiological effects.
