Boys generally begin puberty sometime around age 10. The testicles begin to mature and an initial growth spurt may occur.
The second general stage of puberty usually occurs around age 12 or 13. The testicles continue to grow, and this means that more testosterone will be flowing through the body. Boys continue to grow taller rapidly, at a rate of 5 to 7.5 cm a year. A boy’s body will begin to take on a leaner, more adult and masculine shape.
The third stage of male puberty occurs around age 13 or 14. Pubic hair begins to grow darker and fuller, and the penis now begins to grow in length. Their testicles continue growing, erections become more common and they get taller.
The voice may begin “breaking”. This is when the boy’s voice suddenly and uncontrollably changes pitch mid-word or sentence.
Stage four of male puberty commonly takes place when a boy is around 14 or 15 years old. Hair begins showing up in the armpits and on the face, and pubic hair begins to grow coarse. A boy’s voice will even out and become deeper. There will be more acne because of oily skin. He begins to grow taller and even faster.
