Puberty is the transition from childhood toward physical and reproductive maturity. This lesson explains common changes, the hormones that help initiate puberty, and why its timing differs among individuals.
Puberty is the process—and the period—during which a child’s body develops toward physical and reproductive maturity. It lasts about four years on average, although the pace and timing vary. It typically begins between ages 8 and 13 in females and 9 and 14 in males. These ranges describe common patterns, not deadlines; individual variation is normal.
