Medical Conditions Tied to Early Puberty
Precocious puberty is much more common in girls than in boys. Many girls experience precocious puberty in the absence of any disease or condition. In boys, however, precocious puberty is more likely to be associated with an underlying medical problem. While in many cases the exact cause of precocious puberty cannot be determined, a small number of cases are related to abnormalities of the ovaries or testes, thyroid gland abnormalities or other hormone problems, genetic conditions, tumors or infections of the brain, and injury to the brain.
