What is the mening of puberty?

Puberty is the developmental stage during which a child's body undergoes physical and hormonal changes, leading to sexual maturity and the ability to reproduce. Typically occurring between ages 9 and 14 for girls and 10 and 16 for boys, puberty involves growth spurts, the development of secondary sexual characteristics, and the onset of menstruation in girls and sperm production in boys. This period is marked by significant emotional and psychological changes as well.
