Explanation

In males and females, the adrenal gland produces and secretes increased amounts of several weak androgens during puberty: androstenedione, dehydroepiandrosterone (DHEA) and dehydroepiandrosterone sulfate (DHEA-S). DHEA and DHEA-S are responsible for the commencement of pubic and axillary hair growth.
