Adolescence is a period of a person's development from a child into an adult. During this period, adolescents are going through intense changes in the emotional, psychosocial, cognitive and sexual aspects of an individual’s functioning which affect forming of their personality and behaviour. Sexual changes include going through the processes of physical and sexual maturation which puts adolescents at risk of engaging in acts of risky sexual behaviour, such as engaging in sexual intercourse at an early age, engaging in sexual intercourse with multiple partners, not using of contraceptives, etc. Such behaviours may induce increased risk of developing emotional and behavioural problems that may have a significant impact on adolescents further development and can lead to long-term negative consequences, such as infections with sexually transmitted diseases, juvenile pregnancies, and sexual victimization. It is the duty of professionals, school, family and society to educate adolescents on the topic of reproductive health and responsible sexual behaviour in order to minimize the consequences of risky sexual behaviour. The most successful education is the one in which all the essential individuals and systems work together.
