Central precocious puberty is a term reserved for children with gonadotropin-releasing hormone (GnRH)-dependent early puberty that follows the normal pubertal pattern and the normal control mechanisms through GnRH. Central precocious puberty can be idiopathic or caused by organic conditions such as a central nervous system (CNS) tumor. GnRH-independent isosexual precocity or peripheral precocious puberty is caused by excessive estrogen secretion in girls or androgen secretion in boys from sources other than the GnRH-gonadotropin axis (such as the gonads or the adrenal glands) or by ectopic human chorionic gonadotropin (hCG) secretion. Exogenous sources of sex steroids will also cause peripheral precocious puberty. Pituitary gonadotropins are suppressed by negative feedback in all forms of peripheral precocious puberty because sex steroid secretion is autonomous. Contrasexual (or heterosexual) precocity refers to girls who virilize and boys who feminize.
