Understanding DHEA: The Master Perecsor
DHEA is a steroid thesized primarily in thona reticularis of the adrenal cortex, with minor contritions from the gonades and brain. It circulates in two forms: free DHEA and it sulfated conjugate, DHEAS. DHEAS acts as a stable, long-lived tractiir that can bee converted back into DHEAA in contingeral tissues.

Androgens in Diabetes: A Two- Way Street

Thee mechanisms driving this consiship are multifaceted.

Polycystic ovary syndrome (PCOS), charakteristized by hyperandrogenism, is a major risk factor for insulid resistance and type 2 diabetes.

DHEA, Cortisol, and the HPA Axis in Diabetes

DHEA supplementation may help cort this imbalance. By proving substrate for androgen synthesis and directly modulating glukocorticoid receptor activity, DHEA can reduce cortisol 's negative effects.
