Why Comprehensive Sexual Education is important

Did you know that only 34 % of young people around the world can demonstrate accurate knowledge of HIV prevention and transmission? And that two out of three girls in some countries have no idea of what is happening to them when they begin menstruating? These are some of the reasons why there is an urgent need for quality comprehensive sexuality education (CSE).

What is Comprehensive Sexuality Education?

Comprehensive sexuality education is a curriculum-based process of teaching and learning about the cognitive, emotional, physical and social aspects of sexuality. It aims to equip children and young people with knowledge, skills, attitudes and values that will empower them to realize their health, well-being and dignity; develop respectful social and sexual relationships; consider how their choices affect their own well-being and that of others; and understand and ensure the protection of their rights throughout their lives. It is most effective when comprehensive sexuality education is taught over several years by integrating age-appropriate information that accounts for the developing capacities of young people.


Why do young people need comprehensive sexuality education?

CSE plays a crucial role in addressing the health and well-being of children and young people. Applying a learner-centered approach, CSE not only provides children and young people with age-appropriate and phased education on human rights, gender equality, relationships, reproduction, sexual behaviours risks and prevention of ill health, but also provides an opportunity to present sexuality with a positive approach, emphasizing values such as respect, inclusion, non-discrimination, equality, empathy, responsibility and reciprocity.

CSE should recognize the unique needs of learners, especially vulnerable youth groups – such as LGBTQ+ youth, youth living with disabilities, young people in humanitarian settings, young people who use drugs, young people living with HIV, and young transgender people – and should be tailored to reflect their realities.

Taken together, these programmes help young people develop self-esteem and life skills that encourage critical thinking, clear communication, responsible decision-making and respectful and empathetic behaviour.


According to the International Technical Guidance on Sexuality Education, comprehensive sexuality education must be:

  • Scientifically accurate
  • Incremental
  • Age - and developmentally - appropriate
  • Curriculum based
  • Comprehensive
  • Based on a human rights approach
  • Based on gender equality
  • Culturally relevant and context appropriate
  • Transformative
  • Able to help develop life skills needed to support healthy choices

8 Key Concepts of Comprehensive Sexuality Education (CSE)

What does the evidence say about CSE?

There is significant evidence on the impact of sexuality education. It emphasizes that:

  • Sexuality education has positive effects, including increasing young people’s knowledge and improving their attitudes related to sexual and reproductive health and behaviors.
  • Sexuality education – in or out of schools – does not increase sexual activity, sexual risk-taking behaviour or STI/HIV infection rates.
  • Programmes that promote abstinence as the only option have been found to be ineffective in delaying sexual initiation, reducing the frequency of sex or reducing the number of sexual partners. Programmes that combine a focus on delaying sexual activity with other content are effective.  
  • ‘Gender-focused’ programmes are substantially more effective than ‘gender-blind’ programmes at achieving health outcomes such as reducing rates of unintended pregnancy or STIs..
  • Sexuality education has the most impact when school-based programmes are complemented with the involvement of parents and teachers, training institutes and youth-friendly services.


What is new in the revised Guidance?

The original international technical Guidance published in 2009 positioned sexuality education primarily as part of the HIV response. However, while HIV prevention remains important, evidence and practice demonstrate that sexuality education has a much broader relevance to other issues, not only for young people’s sexual and reproductive health but also for their overall wellbeing and personal development.

The revised Guidance presents sexuality with a positive approach, recognizing that CSE goes beyond educating about reproduction, risks and disease. It reaffirms the position of sexuality education within a framework of human rights and gender equality. It reflects the contribution of sexuality education to the realization of several internationally agreed commitments in relation to sexual and reproductive health, health and well-being, quality and inclusive education, gender equality and women and girls empowerment.
