What mean puberty?

Puberty is the stage of development in which a child's body undergoes physical changes, leading to sexual maturity. It is a natural process that typically occurs during adolescence, usually between the ages of 9 and 14 for girls, and 11 and 16 for boys. During puberty, various changes occur, including the growth of pubic hair, development of breasts in girls, deepening of the voice in boys, growth spurts, and the onset of menstruation in girls. Additionally, hormonal changes during puberty can also lead to emotional and psychological changes.
