Patient's question:
My labia majora are very large and full, and my friends all say that proves my sexual development is good. But my labia majora and mons pubis are smooth and hairless—why is that?Doctor's answer:
The presence or absence, as well as the density, of pubic hair in humans primarily depends on two factors: first, the level of androgens produced by the adrenal cortex in the body; second, the sensitivity of pubic hair follicles to androgens. If, during the period of pubic hair development in females, the level of androgens produced by the adrenal cortex is low for some reason, or if the pubic hair follicles are not sensitive to androgens, it can result in sparse pubic hair or the absence of pubic hair.
