When do boys voices break

Is he hitting puberty too soon? When boys and girls begin puberty , the larynx voice box grows larger and thicker. It happens in both boys and girls, but the change is more evident in boys. When a boy reaches puberty, the production of testosterone increases just as estrogen production increases in girls.

Testosterone, which is produced in the testicles and then travels through the blood throughout the body, causes the cartilage of his larynx to grow. Along with the larynx, the vocal cords grow significantly longer and become thicker. In addition, the facial bones begin to grow. Cavities in the sinuses, the nose, and the back of the throat grow bigger, creating more space in the face and giving the voice more room to resonate.
