Adolescence is a period of significant physical transformation that marks the transition from childhood to adulthood. These changes are driven primarily by hormonal shifts, particularly the increased secretion of sex hormones like testosterone in boys and estrogen and progesterone in girls. The onset of these changes usually occurs between ages 10 and 14 in girls and 11 and 15 in boys, although there is considerable individual variation. In boys, one of the earliest physical changes is the enlargement of the testes and scrotum, followed by growth of the penis. These changes indicate the beginning of reproductive maturity. Alongside this, boys experience an increase in height and weight, with a rapid growth spurt usually occurring around the age of 13 to 15. Muscle mass increases significantly, and shoulders broaden, giving the body a more angular, adult-like appearance.
