  • Beginning of puberty: 9.5 to 14 years old

  • First pubertal change: enlargement of the testicles

  • Penis enlargement: begins approximately one year after the testicles begin enlarging

  • Appearance of pubic hair: 13.5 years old

Girls also experience puberty as a sequence of events, but their pubertal changes usually begin before boys of the same age. Each girl is different and may progress through these changes differently. The following are average ages when puberty changes may occur:

  • Beginning of puberty: 8 to 13 years

  • First pubertal change: breast development

  • Pubic hair development: shortly after breast development

  • Hair under the arms: 12 years old

  • Menstrual periods: 10 to 16.5 years old
