Boys Begin Puberty
Boys wonder when their voices will get deeper, when they'll need to shave, or when their penises will grow. The fact is that physical development starts at different times and progresses at different rates in different people.
So, the beginning of the development that comes with puberty varies from person to person — and that's completely normal. Boys begin their development on average around age 10 or 11, but it's also normal to begin anytime between the ages of 9 and 15.
