Maturation in boys

Adolescence (maturation) in boys it starts at around age 12 -16. Then the shoulders and chest grow. The arms, legs, hands and feet grow especially fast. The facial features change and the facial hair appears on it. Hair grows under the arms as well as pubic hair growth. They can also grow hair on the chest. Testicles and penis increase in size. In boys, especially at the beginning of adolescence, there are so‑called wet dreams. When ejaculation occurs, or the release of the semen outside the body. Wet dreams are proof that sperm production has started in the testes.
During puberty in boys, as a result of the strong growth of the larynx, there is voice change. It consists in changing the sound of the voice from a child’s to a man’s. The boys' voice change usually lasts about two years and is very easily noticeable. It is characterized by a breaking of voice during speaking and difficulties in controlling its height (changing into high and low sounds) and frequent hoarseness.

• The period of puberty is the time when the human body reaches sexual maturity.

• During puberty, many changes take place in boys' bodies (eg bones grow rapidly, pubic hair appears, sweat is increased, voice mutation).

• Changes in the body during puberty are triggered by sex hormones.

• In boys, especially at the beginning of adolescence, there are so‑called wet dreams.
