Precocious puberty



Other Names:
Sexual precocity; Idiopathic sexual precocity; Familial precocious puberty
Subtypes:

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]

Several studies have looked at the long-term effects of treatment with hormone therapy on children with precocious puberty. Long-term hormone treatment has been found to be safe for the reproductive system and helpful in reaching target adult height levels.[2] Additionally, there is little evidence suggesting that long term hormone treatment is associated with psychological or behavioral problems. More studies are needed to determine this association.[3]
