Hair in the pubic, axillary, and underarm regions is described as which term?

• A. Ambosexual
• B. Hypertrichosis
• C. Androgenic alopecia
• D. Vellus hair

Answer: (A)

Pubic and axillary hair is a mature, sexually differentiated type of hair that develops after puberty under hormonal influence—this is the coarse, pigmented hair often referred to as terminal hair. Among the options, ambosexual is the term used in some contexts to describe hair in regions that become androgenically influenced and show sexual differentiation, like the pubic and underarm areas, making it the best fit here. The other terms describe different hair situations: hypertrichosis is excessive hair growth anywhere on the body, androgenic alopecia is hormone-driven hair loss, and vellus hair is the fine, light hair that coats most of the body.
