What is precocious puberty?

Precocious puberty is when a person's sexual and physical traits develop and mature earlier than normal. Normal puberty typically begins between ages 10 and 14 for girls, and ages 12 and 16 for boys. The start of puberty depends on various factors such as family history, nutrition and gender. The cause of precocious puberty is not always known. Some cases of precocious puberty are due to conditions that cause changes in the body's release of hormones. Treatment involves medications that can stop the release of sexual hormones.[1]
