Puberty is the time in life when a boy or girl becomes sexually mature. It is a physical change that usually happens between ages 10 and 14 for girls and ages 12 and 16 for boys. Puberty affects boys and girls differently.
Both boys and girls also usually have a growth spurt (a rapid increase in height) that lasts for about 2 or 3 years. This brings them closer to their adult height, which they reach after puberty.
