Puberty, Teenagers. Adolescence typically describes the years between ages 13 and 19 and can be considered the transitional stage from childhood to adulthood. However, the physical and psychological changes that occur in adolescence can start earlier, during the preteen or tween years (ages 9 through 12).
For girls, changes include the development of breasts and the start of menstruation; for boys, the development of testes. Adolescents do not all begin puberty at the same age. For girls, it may take place anywhere from the age of 8 to 13; in boys, on average, it happens about two years later.
