Training and Counselling of Sex Education as a Prevention for Sexual Risk Behaviour in Adolescents: A Quasi-experiment Study

Adolescents have a high sense of curiosity, including issues of sexuality. Adolescents' curiosity about sexuality is due to the developmental period of adolescents entering puberty, which is marked by the maturation of the reproductive system and the production of sex hormones. Risky sexual behaviour is sexual behaviour that can cause negative impacts such as unwanted pregnancy, abortion and sexually transmitted diseases. Adolescents need to be equipped with various knowledge about reproductive health, which includes understanding the physiology of reproductive organs, menstruation, fertility, sexual orientation, STI/HIV/AIDS prevention techniques, pregnancy, family planning techniques and skills.
