Today’s generation of adolescents is the largest ever – there are 1.2 billion people between the ages of 10 and 19 alive today. To protect their health and rights, young people need evidence-based, accurate information about their sexual and reproductive health, as well as support and skills to feel comfortable and confident about their bodies and their sexuality. While adolescence is a time for growth and learning, often young people confront multiple threats to their health and their lives such as violence and sexual coercion, unintended pregnancies, and sexually transmitted infections (STIs) including HIV. Comprehensive sexuality education (CSE) provides young people with the necessary skills and information to make free and informed decisions about their health, and enjoy safe and satisfying relationships.
