Perception of adolescents about sexuality and reproductive health: the school as a space for sex education

Objective: To analyze adolescents' perceptions and knowledge about Sexually Transmitted Infections (STIs), pregnancy and prevention methods through contraceptive methods. Methodology: This is a descriptive study with a qualitative approach. We used a self-administered questionnaire to collect data in school adolescents from the 6th to the 9th year of elementary school and data analysis was performed through content analysis in its thematic modality. Results: Information on STIs and Contraceptive Methods shows that the adolescents surveyed are vulnerable. The research revealed that most of the adolescents are unaware of the subject or do not have the necessary information to protect themselves. Conclusion: We may consider that there is a gap in the knowledge of school adolescents about contraceptive methods, types of sexually transmitted infections and preventive methods which increases the chances for risky sexual behavior.
