Precocious (Early) Puberty in Children

Puberty is the time when a child’s body and mind start to grow and mature into an adult. Male puberty usually begins at about age 12. Female puberty is at about age 10. Sometimes, though, puberty can start earlier and before signs show. When male puberty starts before age 9 and female puberty before age 8, it is called precocious or early puberty.

Precocious Puberty

Puberty that happens early is called precocious puberty. This means a child's physical signs of sexual maturity develop too soon. This includes breast growth, pubic hair, and voice changes. These are known as secondary sexual characteristics. Precocious puberty happens before age 8 in girls, and before age 9 in boys.
