Early pubic hair, breast, or genital development may result from natural early maturation or from several other conditions.
- Early puberty which is natural in every way except age is termed idiopathic central precocious puberty. It may be partial or transient. Central puberty can also occur prematurely if the inhibitory system of the brain is damaged, or a hypothalamic hamartoma produces pulsatile gonadotropin-releasing hormone (GnRH).
- Secondary sexual development induced by sex steroids from other abnormal sources (gonadal or adrenal tumors, congenital adrenal hyperplasia, etc.) is referred to as peripheral precocious puberty or precocious pseudopuberty.
