Between what ages do the changes of puberty generally occur?

Puberty typically begins between the ages of 8 and 14 for girls and 9 and 15 for boys, although individual experiences may vary. This stage of development is marked by various physical and hormonal changes that signal the transition from childhood into adolescence. Among the changes that occur during this time are the onset of growth spurts, the development of secondary sexual characteristics, and changes in body composition.

The age range of 8 to 14 encapsulates the most common onset of these significant developmental milestones. For girls, this includes breast development and the onset of menstruation, while boys experience increases in muscle mass and voice changes. This timeframe is critical for understanding the biological and social adjustments that occur as adolescents navigate this period of immense change.

Other age ranges provided in the choices either start too late or extend beyond the typical developmental window for the onset of puberty, which is why they do not accurately capture the commonly accepted age range for the onset of these puberty changes.
