Puberty is the process of physical and mental changes during adolescence caused by hormones. Girls typically start puberty between ages 10-11 and finish between 15-17, while boys start between 11-12 and finish between 16-17. Changes include growth spurts, body hair, body odor, acne, voice changes in boys, and menstruation in girls. Puberty prepares the body for adulthood and ends between ages 18-20.
