Endogenous Cushing's syndrome can occur when the body produces excess cortisol.

Dehydroepiandrosterone (DHEA) is a steroid hormone produced in the adrenal cortex from cholesterol. [5] It is the primary precursor of both the androgen and estrogen sex hormones. DHEA is also called dehydroisoandrosterone or dehydroandrosterone. Androstenedione (A4) is an androgenic steroid produced by the testes, adrenal cortex, and ovaries.
