In short

Puberty is the time in life when a boy or girl becomes sexually mature, usually happening between ages 8 and 13 for girls and ages 9 and 14 for boys. In girls, the first sign is usually breast development, followed by hair growth in the pubic area and armpits, with menstruation usually happening last. In boys, puberty usually begins with the testicles and penis getting bigger, followed by hair growth in the pubic area and armpits, muscle growth, a deepening voice, and facial hair development. Both boys and girls may get acne and usually experience a growth spurt lasting about 2 or 3 years.

Description

Puberty is the time in life when a boy or girl becomes sexually mature. It is a process that usually happens between ages 8 and 13 for girls and ages 9 and 14 for boys. It causes physical changes and affects boys and girls differently.
In girls:
The first sign of puberty is usually breast development.
Then hair grows in the pubic area and armpits.
Menstruation (or a period) usually happens last.
In boys:
Puberty usually begins with the testicles and penis getting bigger.
Then hair grows in the pubic area and armpits.
Muscles grow, the voice deepens, and facial hair develops as puberty continues.
Both boys and girls may get acne. They also usually have a growth spurt (a rapid increase in height) that lasts for about 2 or 3 years. This brings them closer to their adult height, which they reach after puberty.

About this page. This page brings together public information from official sources, each cited where it is used. It is not medical advice, it is not a diagnosis, and it does not tell you which treatment to take.

Treatments. Indications are quoted unchanged from official product information (European Medicines Agency, U.S. Food and Drug Administration). They describe what a medicine is approved for, not whether it is right for you. Approved uses can differ between countries. Always read the package leaflet and follow your doctor's or pharmacist's advice.

What people report. Figures marked "reported by Anpheros users" are anonymous counts from at least 20 people who agreed to share them. They show what people report, not what works, and they are not clinical evidence.

Links between terms. "May be associated with" means the link appears in a cited source. It does not mean you have that condition.

In an emergency, call 112 (or your local emergency number). Do not delay seeking medical help because of something you read here.
