what happens to boys during puberty
Quick Scoop
Puberty in boys is the time when the body changes from a child’s body into an adult body, with hormones like testosterone driving growth and sexual maturity. It usually starts with the testicles and scrotum growing, then the penis enlarging, followed by pubic hair, voice changes, more body hair, a growth spurt, and more muscle.[1][5][9]What changes happen
- Genitals grow. The testicles usually get bigger first, and the scrotum may darken and hang lower. [7][1]
- Hair appears. Pubic hair comes first, then underarm, facial, chest, and leg hair may grow later. [3][9][1]
- Voice changes. The voice often cracks before it gets deeper. [9][3]
- Body grows fast. Many boys have a growth spurt and become taller, heavier, and more muscular. [5][3][9]
- Skin and sweat change. More sweating and body odor are common, and acne can happen too. [3]
- Sexual development starts. Erections become more common, ejaculation can begin, and wet dreams may happen. [5][9]
Feelings and behavior
Puberty is not only physical. Boys may feel awkward, moody, angry, excited, or confused as their bodies and emotions change quickly.
[2][4]What is normal
It is normal for puberty to start at different ages and move at different speeds. Some boys also have temporary breast growth, called gynecomastia, which often goes away.
[9][5]When to get help
It is a good idea to talk to a doctor if puberty seems very early, very late, or if changes are painful or worrying. A trusted adult can also help explain what is happening in simple terms.
[4][1]TL;DR: Boys’ puberty usually means bigger testicles and penis, pubic and body hair, voice changes, growth spurts, more sweating, and emotional ups and downs.
