Amar Kumar 8 years, 3 months ago

Puberty:It is the time when a young person’s sexual and reproductive organs mature. Before any physical changes happen, the body starts to make hormones that trigger sexual development and growth. Puberty starts at around 10 years for girls and 12 years for boys, give or take a year or so. Physical changes can be seen at around 10 to 14 years for most girls and around 11 to 15 years for most boys. A lot of emotional changes happen alongside these physical changes and young people also start to think differently.

Puberty can be an unsettling time for a young person. It can also be an exciting time as they move from childhood to adulthood, and take on the rights and responsibilities that come with being an adult. Adjusting to the many changes that happen around puberty can be difficult for both parents and young people. It can help to remember that everyone needs to be understanding and patient.
