Puberty for Boys
Among the changes boys will notice:
- A growth spurt. A boy's arms, legs, hands and feet may grow rapidly, as he gets taller and his shoulders broaden.
- Changes to penis and testes. The penis and testes will grow and boys may experience more erections as a result of an increase in sex hormones.
- Voice deepens. Boys develop deeper voices (though their voices may crack before they deepen).
- Hair growth. Hair will begin to grow on legs, face, underarms, and in the pubic area.
