Currently, 79% of adolescents report using some form of contraception at first intercourse and 86% used a method to prevent pregnancy at last intercourse. These trends and the availability of long-acting reversible contraceptive methods and emergency contraception have resulted in substantial declines in rates of teenage pregnancy, births, and abortion.
