Pubic hair is the hair in the frontal genital area of adolescent and adult humans, located on and around the sex organs, the crotch, and sometimes at the top of the inside of the thighs, in the pubic region around the pubis bone.
Although fine vellus hair is present in the area in childhood, pubic hair is considered to be the heavier, longer and coarser hair that develops during puberty as an effect of rising levels of androgens. Pubic hair is therefore part of the androgenic hair (or body hair) and is a secondary sex characteristic.
Hair does not in itself have any intrinsic sexual value other than the attributes given to it by individuals in a cultural context. Some cultures are ambivalent in relation to particular body hair, with some being regarded as attractive while others being regarded as unaesthetic. Many cultures regard pubic hair to be erotic. In most cultures, both men and women are expected to cover their pubic hair at all times, but sometimes this is because it is associated with genitalia.
