In addition to provoking shame about a nearly universal activity, abstinence-only sex education is ineffective and dangerous. Last April, a 10-year study found that students who took abstinence-only courses were no more likely to abstain from sex than other students. Previous studies revealed that abstinence-only students avoid using contraception.

Programs in public schools teach patently false information like “the chances of getting pregnant with a condom are one out of six” and H.I.V. “may be in your body for a long time (from a few months to as long as 10 years or more) before it can be detected.”

The results are tragic. The United States has the highest teenage pregnancy rate in the developed world (about the same as Ukraine’s), and the highest abortion rate in the Western world. Sexually transmitted infections like syphilis and gonorrhea are on the rise for the first time since the 1980s, and chlamydia is being diagnosed twice as often as it was a decade ago.

Among Americans living in poverty — those who might see the $4 price of a three-pack of condoms as the take-home pay for an hour of work at minimum wage — the unintended pregnancy rate has increased 30 percent since 1994.

Our teenage pregnancy and abortion rates have declined during the last decade, but research suggests this is mainly because of increased use of condoms, something young people must learn about outside of school.
