Pubarche
Pubarche refers to the first appearance of pubic hair in a child. Pubarche is one of the physical changes of puberty but should not be equated with it since it may occur independently of complete puberty. Pubarche usually results from rising levels of androgens from the adrenal glands or the testes but may also result from exposure of a child to an anabolic steroid.
