Another physical change that is observed in adolescent boys is the change in their voices. Their vocal cords grow and as a result, the voice pitch changes into a heavier tone.

Physical development and changes at such a sudden and fast rate is quite something for the adolescent kid to deal with. This is the time when the child is in constant need of support and care.
