when do you start puberty
Puberty doesn't happen all at once â it happens in stages. Guys usually start puberty later than girls, when they're around 10 to 12 years old. Some start sooner and others later. You may continue to go through puberty changes until you're 20 years old. A guy may show some signs of puberty at an early age (like a voice that's starting to crack) but may not show other signs of puberty until years later (like growing facial hair).
Puberty is a time when your body goes through many changesâyouâre growing both physically and emotionally from a child into a teenager and eventually into an adult. Although puberty doesnât happen at the same time for everyone, it usually starts between 8 and 13 years for girls.
