For a Boy
The physical changes of puberty for a boy usually start with enlargement of the testicles and sprouting of pubic hair, followed by a growth spurt between ages 10 and 16 on average 1 to 2 years later than when girls start. His arms, legs, hands, and feet also grow faster than the rest of his body. His body shape will begin to change as his shoulders broaden and he gains weight and muscle.
A boy may become concerned if he notices tenderness or swelling under his nipples. This temporary development of breast tissue is called gynecomastia and it happens to about 50% of boys during puberty. But it usually disappears within 6 months or so.
And that first crack in the voice is a sign that his voice is changing and will become deeper.
Dark, coarse, curly hair will also sprout just above his penis and on his scrotum, and later under his arms and in the beard area. His penis and testes will get larger, and erections, which a boy begins experiencing as an infant, will become more frequent. Ejaculation the release of sperm-containing semen will also occur.
Many boys become concerned about their penis size. A boy may need reassurance, particularly if he tends to be a later developer and he compares himself with boys who are further along in puberty. If a boy is circumcised, he may also have questions about the skin that covers the tip of an uncircumcised penis.
