Contraception

Adolescents may lack knowledge of, or access to, conventional methods of preventing pregnancy, as they may be too embarrassed or frightened to seek such information.

In the United States, according to the 2002 National Surveys of Family Growth, in 2002, sexually active adolescent women wishing to avoid pregnancy were less likely than those of other ages to use contraceptives (18% of 15- to 19-year-olds used no contraceptives, versus 10.7% average for women ages 15 to 44). More than 80% of teen pregnancies are unintended. Over half of unintended pregnancies were to women not using contraceptives, most of the rest are due to inconsistent or incorrect use. 23% of sexually active young women in a 1996 Seventeen magazine poll admitted to having had unprotected sex with a partner who did not use a condom, while 70% of girls in a 1997 PARADE poll claimed it was embarrassing to buy birth control or request information from a doctor.^[22]

Among teens in the UK seeking an abortion, a study found that the rate of contraceptive use was roughly the same for teens as for older women.

In other cases, contraception is used, but proves to be inadequate. Inexperienced adolescents may use condoms incorrectly or forget to take oral contraceptives. Contraceptive failure rates are higher for teenagers, particularly poor ones, than for older users. Reversible longer term methods such as intrauterine devices, subcutaneous implants, or injections (Depo provera, Combined injectable contraceptive), require less frequent user action, lasting from a month to years, and may prevent pregnancy more effectively in women who have trouble following routines, including many young women. The simultaneous use of more than one contraceptive measure further decreases the risk of unplanned pregnancy, and if one is a condom barrier method, the transmission of sexually transmitted disease is also reduced
