Adolescence, a period of transition between childhood and adulthood, refers to the time when individuals undergo physiological changes that are also reflected in social changes with the awakening of sexuality. During this time, young people explore this novelty, dealing with romantic and sexual desires, and from this, a lack of guidance stemming from a scarcity of information can impact the adolescent’s health, social context, and future. School dropout, discrimination, and the potential biological consequences of pregnancy are examples of how a young person’s life can be affected. Thus, this study evaluated the perception of teenage pregnancy and its repercussions. The study was conducted in two public schools in the municipality of Paudalho/PE, with the participation of 193 students aged 15 to 19, who answered questionnaires on the topic studied. Based on the data obtained, educational measures were implemented to guide students on behaviors that should be adopted to prevent sexually transmitted infections and unplanned pregnancies.
