Detailed explanation-1: -The androgenic hormones, dehydroepiandrosterone (DHEA) and androstenedione, are produced by the adrenal glands and act as precursors in the estrogen and testosterone hormones production [21, 22].
Detailed explanation-2: -Androstenedione is a direct precursor of testosterone and estrone in both males and females; it might ↑ testosterone levels.
Detailed explanation-3: -DHEA serves as a precursor for other hormones including testosterone and estrogen. The sulfated form of DHEA, DHEAS, is specific for the adrenal glands.
Detailed explanation-4: -Aromatase expressing cells in the brain convert circulating testosterone into estrogen, and it is this local estrogen that is thought to control dimorphic behaviors in males (Figure 1A) (MacLusky and Naftolin, 1981; Naftolin and Ryan, 1975).
