FACT SHEET: What the Research Shows: Helping Teens Make Healthy and Responsible Decisions about Sex

Evidence shows that sexuality education that stresses the importance of waiting to have sex while providing accurate, age-appropriate, and complete information about how to use contraceptives effectively to prevent unintended pregnancy and STDs can help teens make healthy and responsible life decisions. Yet there is currently no federal program dedicated to supporting this approach. Instead, since 1996, the federal government has funneled more than a billion dollars into abstinence-only-until-marriage programming, even in the face of clear evidence that these programs do not work.

Below is a review of recent research on the issue of sexuality education:


Giving teens the information they need to make responsible life decisions about sexuality helps teens delay sex and protects their health.

  • A review of a large body of evaluation research on programs to prevent teenage pregnancy found conclusive evidence that sexuality education that discusses the importance of delaying sex and includes accurate information about contraceptive use does not increase sexual activity nor hasten the onset of first intercourse. To the contrary, several of these programs have been shown to delay the onset of sex or increase condom or other contraceptive use among sexually active teens.

  • The Centers for Disease Control & Prevention note that “research has clearly shown that the most effective programs [to prevent the spread of HIV/AIDS] are comprehensive ones that include a focus on delaying sexual behavior and provide information on how sexually active young people can protect themselves.

Parents want schools to teach comprehensive sexuality education and do not think taxpayer dollars should be spent on abstinence-only-until-marriage programs.

  • More than 85 percent of Americans believe that it is appropriate for school-based sex education programs to teach students how to use and where to get contraceptives.

  • Seventy percent of Americans oppose the use of federal funds for abstinence-only-until-marriage programs that prohibit teaching about the use of condoms and contraception for the prevention of unintended pregnancies and STDs.

Studies show that most abstinence-only-until-marriage programs are ineffective, and some show that these programs deter teens who become sexually active from protecting themselves from unintended pregnancy and STDs.

  • A rigorous, multi-year, scientific evaluation authorized by Congress presents clear evidence that abstinence-only-until-marriage programs don’t work. The study, which looked at four federally funded program participants were just as likely to have sex before marriage as teens who did not participate. Furthermore, program participants had first intercourse at the same mean age and the same number of sexual partners as teens who did not participate in the federally funded programs.

Christopher Trenholm et al., Impacts of Four Title V, Section 510 Abstinence Education Programs,, Princeton: Mathematica Policy Research, Inc., April 2007.

  • A review of program evaluations in 11 states (AZ, CA, FL, IA, MD, MN, MO, NE, OR, PA, WA) indicates that after participating in abstinence-only-until-marriage programs, teens are less willing to use contraception, including condoms. And in only one state, did any program demonstrate any success in delaying the initiation of sex.

  • Some abstinence-only-until-marriage programs include “Virginity Pledges,” whereby teens sign cards promising to remain virgins until they are married. While data suggests that under limited circumstances, teens who sign a pledge may delay sexual intercourse, 88 percent still have sex before marriage. Research also shows that pledgers’ rate of STDs does not differ from the rate of nonpledgers and that pledgers are less likely to use condoms at first intercourse or to be tested for STDs than nonpledgers.

A recent congressional report round that widely used federally funded abstinence-only-until-marriage curricula distort information, misrepresent the facts, and promote gender stereotypes.

  • More than 80 percent of the abstinence-only-until-marriage curricula reviewed contain false, misleading or distorted information about reproductive health.
  • The curricula reviewed misrepresent the effectiveness of contraceptives in preventing STDs and unintended pregnancy. They also contain false information about the risks of abortion, blur religion and science, promote gender stereotypes, and contain basic scientific errors.
