Sex education provides instruction on issues relating to human sexuality, including relationships, anatomy, activity, reproduction, consent, health and rights. Comprehensive sex education covers all these topics, while some advocate abstinence-only education. Most adults and adolescents support sex education in schools. Studies show comprehensive sex education that includes contraceptive information reduces risky behaviors and unintended pregnancies more than abstinence-only programs. Discussions on gender, rights, equality and roles can promote healthy attitudes. However, topics like LGBT education remain controversial due to some religious and parental objections.
