What causes precocious puberty?

In the majority of cases of precocious puberty, no underlying cause can be identified. When a cause cannot be identified, the condition is called idiopathic precocious puberty.Sometimes the cause is an abnormality involving the brain. In other children, the signs of puberty occur because of a problem such as a tumor or genetic abnormality in the ovaries, testes, or adrenal glands, causing overproduction of .... hormones.Precocious puberty can be divided into two categories, depending on where in the body the abnormality occurs—central precocious puberty and peripheral precocious puberty.
