An intense social and political debate continues in the United States regarding sexuality education. Included in the debate are those who favor comprehensive approaches, those who favor abstinence-only approaches, and those who favor no sexuality education. In this study, we showed that men who received school-based condom education were less likely to have been diagnosed with sexually transmitted infections (STIs) and were more likely to ever have been tested for sexually transmitted infections than were men without such education. School-based condom education is associated with less, rather than more, STI risk.
