Pubic
Pubic hair is a collection of coarse hair found in the pubic region. It will often also grow on the thighs and abdomen. Zoologist Desmond Morris disputes theories that it developed to signal sexual maturity or protect the skin from chafing during copulation, and prefers the explanation that pubic hair acts as a scent trap.
The genital area of males and females are first inhabited by shorter, lighter vellus hairs that are next to invisible and only begin to develop into darker, thicker pubic hair at puberty. At this time, the pituitary gland secretes gonadotropin hormones which trigger the production of testosterone in the ovaries and testicles, respectively, promoting pubic hair growth. The average ages pubic hair begins to grow in males and females are 12 and 11, respectively.
Just as individual people differ in scalp hair color, they can also differ in pubic hair color. Differences in thickness, growth rate, and length are also evident.
Women of various cultures are encouraged to remove their pubic hair, for example Muslim women may shave their pubic area for reasons of cleanliness to do with their religion. In Western culture, in the 1970s women were frequently portrayed in the media with full pubic hair, but in the following decades trends have influenced women to undertake more and more extreme forms of hair removal.
