Contraceptive Failure Rates for Teens

The chart below compares some of the reversible contraceptives discussed in this guide. Each method is listed with its failure rate for women aged 18-19, based on data from two large studies (National Survey of Family Growth). The "one year" failure rate is the percentage of women who become pregnant after one year of using the method listed. The "two year" rate is the percentage of women who have become pregnant after two years of using the method listed. The percentage

The probability of a contraceptive failure multiplies over time. Failure rates for most of these methods are higher for teens than adults because teens are more fertile than older couples, and they are less likely to use the methods consistently and correctly.
