Sex education, also known as sexual education, sexuality education or sex ed, is the instruction of issues relating to human sexuality, including human sexual anatomy, sexual activity, sexual reproduction, safe sex, birth control, sexual and reproductive health, emotional relationships and responsibilities, age of consent, and reproductive rights.
Sex education that includes all of these issues is known as comprehensive sexuality education. In contrast, abstinence-only sex education, which focuses solely on promoting sexual abstinence, is often favored in more socially conservative regions, including some parts of the United States.
Sex education may be provided as part of school programs, public health campaigns, or by parents or caregivers. In some countries, it is known as "relationships and sexual health education".
Many governments see it as beneficial to provide public education on such matters before or at the beginning of puberty to improve public health, to limit the spread of sexually transmitted infections, and to avoid teenage pregnancy and unwanted pregnancies later on.

History
In multiple cultures, the discussion of all sexual issues has traditionally been considered taboo, and adolescents were not given any information on sexual matters. Such instruction, as was given, was traditionally left to a child's parents, and it was often put off until just before their marriage. However, in the late 19th century, the progressive education movement led to the introduction of sex education as "social hygiene" in North American school curricula and the introduction of school-based sex education.
During the Second World War, UK governmental concerns grew around mass relocation, parentless youths, and young men and women working together for the first time. Not only were there fears of new sexually transmitted diseases, but there was also growing anxiety around young pregnancy, putting pressure on the war-ravaged economy and healthcare system. As such, the UK Board for Education introduced the Sex Education in Schools and Youth Organizations guidance. This placed the onus of sex education on schools and youth groups and guided leaders on how to implement it. For example, the mechanics of sexual intercourse could be communicated via "the keeping of livestock", as students could observe reproduction in real-time; the guidance also encouraged discussions about menstruation, motherhood courses, and personal hygiene talks. Popular among teachers and some parents, this guidance – which made sex education a possibility, not an obligation – prevailed for many years in the UK.
After the Second World War, some developing countries promoted sex education programs that evolved to address political goals. A growing anxiety in some areas of the world over rising birth rates led to population-centered sex education programs. For instance, the first sex education curriculum in Singapore between 1966 and 1973 emphasized birth control as a way to avoid overpopulation. Reforms in some socialist countries focused on the role of sex education in strengthening family ties within society. This was the focus of sex education programs that developed in the German Democratic Republic (GDR) and Cuba during the late twentieth century. The evolving content of sex education programs reflected shifting opinions regarding sexuality within each society. For example, Swedish sex education guidelines and textbooks published between 1945 and 2000 originally depicted masturbation as inherently harmful but increasingly portrayed it as natural and harmless.
The Catholic Church referred to the need for "a positive and prudent sexual education" in its 1965 Declaration on Christian Education, one of the documents issued by the Second Vatican Council.
Definitions
Leepson sees sex education as instruction in various physiological, psychological, and sociological aspects of sexual response and reproduction. Kearney (2008) also defined sex education as "involving a comprehensive course of action by the school, calculated to bring about the socially desirable attitudes, practices and personal conduct on the part of children and adults, that will best protect the individual as a human and the family as a social institution."
Thus, sex education may also be described as "sexuality education", which means that it encompasses education about all aspects of sexuality, including information about family planning, reproduction (fertilization, conception and development of the embryo and fetus, through to childbirth), plus information about all aspects of one's sexuality including: body image, sexual orientation, sexual pleasure, values, decision making, communication, dating, relationships, sexually transmitted infections (STIs) and how to avoid them, and birth control methods.
Various aspects of sex education are considered appropriate in school depending on the age of the students or what the children can comprehend at a particular point in time. Rubin and Kindendall expressed that sex education is not merely the topics of reproduction and teaching how babies are conceived and born. Instead, it has a far richer scope and goal of helping children incorporate sex more meaningfully into their present and future life, and to provide them with some basic understanding of virtually every aspect of sex by the time they reach full maturity.
Sex education delivered via in-person classroom instruction and workshops led by teachers or trained sex educators is commonly referred to as school-based sex education.
Impacts of sex education
The United Nations Population Fund (UNFPA) recommends comprehensive sexuality education, as it enables young people to make informed decisions about their sexuality. According to UNFPA, it is taught over several years, introducing age-appropriate information consistent with the evolving capacities of young people. It includes scientifically accurate, curriculum-based information about human development, anatomy, and pregnancy. It also includes information about contraception and sexually transmitted infections (STIs), including HIV. And it goes beyond information to encourage confidence and improved communication skills. According to UNFPA, curricula should also address the social issues surrounding sexuality and reproduction, including cultural norms, family life, and interpersonal relationships.
The reach of comprehensive sexual education
A U.S. review concludes that "the overwhelming weight of evidence shows that sex education that discusses contraception does not increase sexual activity". The 2007 study found that "No comprehensive program hastened the initiation of sex or increased the frequency of sex, results that many people fear." Additionally, the report showed "Comprehensive programs worked for both genders, for all major ethnic groups, for sexually inexperienced and experienced teens, in different settings, and in different communities."
Further, evidence shows that a combination of comprehensive sexuality education and access to birth control appears to decrease the rates of unintended pregnancies among teenagers. A meta-analysis that compared comprehensive sexuality education programs with abstinence-only programs found that abstinence-only programs did not reduce the likelihood of pregnancy, but rather may have increased it. Studies show that curricula providing accurate information about condoms and contraception can lead to reductions in the risky behaviors reported by young people as well as reductions in unintended pregnancies and STIs. Programs that teach only abstinence are ineffective. The individuals in this study were also found to be less likely to engage in violent relationships and to have a lower rate of STIs (including HIV) and unintended pregnancy.
Other studies have found that "few sexual health interventions are designed with input from adolescents. Adolescents have suggested that sex education should be more positive with less emphasis on anatomy and scare tactics; it should focus on negotiation skills in sexual relationships and communication; and details of sexual health clinics should be advertised in areas that adolescents frequent (for example, school toilets, shopping centers)."
According to the United Nations Population Fund, human rights issues, gender equality, and gender roles should be integrated into every aspect of these discussions. This includes human rights protection, fulfillment, and empowerment; the impact of gender discrimination; the importance of equality and gender-sensitivity; and the ideas underlying gender roles.
Sexual rights/violence discussions
The United Nations Population Fund argues that sexual abuse, gender-based violence, and harmful practices should be discussed according to the global organization on reproductive rights. By definition, sexual assault is any sexual activity without clear, voluntary, and ongoing verbal consent, through force, manipulation, or coercion. Sexual violence is a deep-rooted issue in current society, stemming from a need for power and control. It is further propagated by societal norms that tolerate inequality. Taken together to form comprehensive sex education, all this information teaches young people the life skills necessary to assume responsibility for their own behavior and to respect the rights of others."
Comprehensive sexual education “enables young people to make informed decisions about their sexuality and health,” allowing for younger generations to understand concepts of human rights and gender equality. Such skills have been shown to lead to better-informed decisions regarding sex, sexual violence, and consent.
Including this information in Sex Ed courses not only shows what consent looks like but also breaks free of societal norms that lead to violence and teaches students to recognize signs of assault or abuse. Research shows that people who receive comprehensive sex ed are better equipped to speak out against negative behaviors, support victims, and respect the boundaries of others. Studies concluded that by bringing in this knowledge at an early age, correct morals during sexual interactions are ingrained in their lives and will allow them to apply this knowledge in their futures to help victims and speak out against aggressors, allowing them to build safer communities.
However, sexual violence is not always physical; it can be emotional, mental, and psychological manipulation as well. Broader systems of oppression, such as racism and sexism, often reinforce societal beliefs that normalize abuse, while the media and everyday jokes have created environments where sexism, objectification, and violence have become easily dismissed.
Additionally, according to UNFPA, "A 2010 review found that 'gender-focused' curricula – meaning curricula that integrate gender equality into the learning material – were substantially more effective in reducing risky behaviors than programs that did not consider gender." Research has also shown that delay in sexual initiation and the use of condoms and other contraception have been a result of young people adopting egalitarian attitudes towards gender roles.
Case studies
US study on sex-ed and college violence
In the United States, sex-ed curricula, most of which are abstinence-only and abstinence-plus approaches, don't include education on consent or on prevention of sexual violence. While 29 out of 50 states (plus DC) mandate Sex-Ed to be taught in schools, only 16 states (plus DC) mandate the teaching of consent in sexual education, which Caulfield et al. argue has negative effects on the way consent and rape are managed in a collegiate environment.
Caulfield et al. conducted a 2024 experiment to examine the effects of different kinds of sexual education on college students’ experiences with sexual violence and rape myth acceptance. In doing their study, they contacted over 600 students, and measured their level of acceptance of rape myths, experience with sexual violence, and type of sexual education received. Their results indicated that those who received comprehensive sexual education during high school were 2.5 times more likely to be taught about consent than those who did not receive comprehensive sex education, indicating that consent education is commonly part of comprehensive sex-ed. Further, the study found that those who were taught consent had a 51% lower likelihood of being sexually victimized than those who were not taught consent.
US–Netherlands study on attitudes towards sex
When places have more comprehensive sexuality education, STI and pregnancy rates drop. The attitudes of children have also been found to differ depending on the content of their sex education. One comparison of results can be made between the sex education curriculum in the Netherlands and that in the US. On average teens in Europe and the Netherlands (which have more comprehensive sex ed) do not have sex at a younger age than teens in the US (with less comprehensive sex ed); however teens in the Netherlands report having a positive and consensual first sexual experience while 66% of sexually active US teens report that they wished they waited longer for their first sexual experience.
Nine out of ten teens in the Netherlands use contraception during their first sexual experience, which contributes to the lower pregnancy and STI rates. More comprehensive sex ed starting at the elementary level resulted in appreciation of sexual diversity, dating and intimate partner violence prevention, development of healthy relationships, prevention of child sex abuse, improved social/emotional learning, and increased media literacy.
