A growing number of States worldwide have confirmed their commitment to comprehensive sexuality education as an essential priority for achieving national development, health and education goals. In its resolution 70/137, the General Assembly called upon all States to develop and implement educational programmes and teaching materials, as well as teacher education and training programmes for both formal and non-formal education, including comprehensive evidence-based education on human sexuality, based on full and accurate information, for all adolescents and youth; to modify the social and cultural patterns of conduct of men and women of all ages; to eliminate prejudices; and to promote and build decision-making, communication and risk reduction skills for the development of respectful relationships based on gender equality and human rights.
