Is precocious puberty congenital?
Congenital adrenal hyperplasia (CAH) is a recognized cause of precocious pseudopuberty. Some children with CAH also develop true precocious puberty with early maturation of the hypothalamic-pituitary-gonadal axis.
What are the two types of precocious puberty?
There are three types of precocious puberty that may affect a child: central precocious puberty (the most common type), peripheral precocious puberty and incomplete puberty. Central precocious puberty: Central precocious puberty occurs when sex hormones are released too early.
What is Pseudopuberty?
Peripheral precocious puberty, also known as precocious pseudo puberty, is gonadotropin-independent and occurs due to excess production of sex hormones either from the gonads, the adrenal glands, ectopic or exogenous sources.

Why does my 5 year old daughter have pubic hair?
Premature pubarche, or the development of pubic hair before the age of 8 in girls or 9 in boys, is most commonly caused by premature adrenarche. Adrenarche is the maturation of the adrenal zona reticularis in both boys and girls, resulting in the development of pubic hair, axillary hair, and adult apocrine body odor.
Is it normal for a 6 year old to have pubic hair?
Hormonal basis
It is normal for production of these hormones to increase (something we call adrenarche) and for pubic hair to appear after age 8 in girls or 9 in boys. The reason why this increase occurs earlier in some children is not known.
What kind of tumors cause precocious puberty?
Central precocious puberty (CPP) is caused by abnormality in the hypothalamus-pituitary-gonadal axis. Most cases of CPP are idiopathic, and, in rare situations, central nervous system (CNS) tumors, such as hypothalamic hamartoma, astrocytoma, optical glioma, ependymoma, or craniopharyngioma, may be the cause of CPP.
What is the most common cause of precocious puberty?
What causes precocious puberty? It may be caused by tumors or growths on the ovaries, adrenal glands, pituitary gland, or brain. Other causes may include central nervous system problems, family history of the disease, or certain rare genetic syndromes. In many cases, no cause can be found for the disorder.
