What is precocious puberty (early puberty)?
Abnormally early puberty is called precocious puberty and is characterized by the early development of sexual characteristics in girls before the age of 8 and in boys before the age of 9. Most children with the disorder grow fast at first, but also finish growing before reaching their full genetic height potential. Left untreated, most boys will not grow taller than 5 feet 2 inches, and girls often do not grow taller than 5 feet.
