In Bolivia, men represent 49 percent of the population, that is, almost half of the population (INE, 2012), in which the presence of adolescents and young people is prevalent. National health data (ENDSA, 2008) indicate that many of these adolescents begin sexual activity at age 13, voluntarily or under pressure, with or without protection. This material demonstrates the importance of working with men to prevent unplanned pregnancies.
