The crucial report has pointed out that sex education in primary education is compulsory in 68 percent of countries and secondary education in 76 percent. More than six in 10 countries cover topics such as gender roles, sexual and domestic abuse, and gender-based violence. One in two countries covers the concept of mutual consent. Contraception issues are covered in the school curriculum in two-thirds of the countries.
