Medical Terms for Extra Hair. Hirsutism refers to increased hair in the so-called sexual distribution. Sexual distribution simply means skin areas on which men and women have different amounts of hair. Hair growth on these areas is due to the effect of testosterone on the hair follicle.
The hormones with the most direct effect on hair growth are androgens, the male sex hormones that include testosterone. Both men and women produce androgens--a gender just produces more of one and less of the other. Facial and body hair are considered secondary sex characteristics that form in response to androgens.
