Introduction: The National Autonomous University of Mexico Faculty of Medicine created the Adolescent Pregnancy PreventionProgram, which is aimed at students. Objective: To determine the sexual-reproductive health profile of medical students through a diagnostic questionnaire and of those who participated in an educational intervention on sexuality (three modules). Method: First-year undergraduate students, schoolyear 2017-2018, participated. Students were considered to be trained when they took at least one module. Results: The questionnaire was answered by 1157 students, 21.9 % participated in at least one module, 43.1% had initiated sexual activity and 25 % received the educational intervention. Not having used a condom in their last intercourse was identified in 20 %, and a high prevalence of intercourse under the influence of alcohol was observed. Conclusions: It is important for specific sexuality competences to be promoted among those who will be doctors in the future.
