There is no scientific evidence that abstinence-only-until-marriage programs—those that censor information about contraception—are effective.
On the other hand, research continues to show that comprehensive sex education, which teaches both abstinence and contraception, is most effective for young people. Youth who receive this kind of education are more likely to initiate sexual activity later in life and use protection correctly and consistently when they do become sexually active. Evaluations of comprehensive sex education programs show that these programs can delay the onset of sexual activity, reduce the frequency of sexual activity, reduce the number of sexual partners, and increase condom and contraceptive use. Importantly, the evidence shows that these programs do not encourage teens to become sexually active. In short, responsible sex education programs can work!
Evaluations and Reports on Abstinence-Only Programs
Repeated evaluations of abstinence-only programs have repeatedly found that these programs not only spread myths and bias, but are ineffective.
