(HealthDay News) -- Puberty can be a confusing and frustrating time for boys as their voices change. The larynx, also known as the voice box, grows during puberty because of bursts in testosterone. The growth and strengthening of the vocal cords help make the voice deeper.
As your body adjusts to the change, your voice may crack or break, but this only lasts a few months, says KidsHealth. Everyone goes through puberty at different times, so some kids' voices change earlier and some change later.
If you're going through this now, KidsHealth suggests talking to a parent, older sibling or friend who has already gone through a voice change.
