Puberty (or adolescence) is the time when a child begins to change into an adult.
The changes affect the way people look, feel, think, and relate to others.
Some of these changes might feel great, while others may be confusing or feel uncomfortable.
Puberty usually happens between the ages of 9 and 16. Many boys will notice changes around the age of 12 or 13. Many girls will notice changes around the age of 10 or 11. It’s different for everybody. Puberty will start at the time that is right for each person.
NOTE: Everyone is not the same.
It is important to understand that general information about body changes and the reproductive system is not true for everyone. A small percentage of people are intersex – they have natural variations from conventional ‘female’ or ‘male’ bodies, including genital, chromosomal and/or a range of other physical characteristics. This is totally normal for them. Also, some people are transgendered and so their gender identity may be different from the sex they were assigned at birth.
