Sex education is instruction on issues relating to human sexuality, including human sexual anatomy, sexual reproduction, sexual activity, reproductive health, emotional relations, reproductive rights and responsibilities, sexual abstinence, and birth control. Common avenues for sex education are parents or caregivers, formal school programs, and public health campaigns.
Evidence shows that a combination of comprehensive sex education and access to birth control appears to decrease the rates of unintended pregnancies among teenagers. A meta-analysis compared comprehensive sex education programs with abstinence-only programs found that abstinence-only programs did not reduce the likelihood of pregnancy, but rather may increased it.
"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 centres)."
