Abstract:
The decline in adolescent pregnancy rates noted in the 1990s has been attributed to more teenagers choosing abstinence, the availability of long-acting contraceptive options, and the increased use of condoms. Many adolescents remain at risk of unplanned pregnancy, however, because of method failure, inconsistent or incorrect use, or discontinuation of a method without choosing another method. Practitioners who care for adolescents and young women have access to several new methods in 2003. Recent additions include a contraceptive transdermal patch, a hormone-releasing intravaginal ring, new formulations of pills, and a new intrauterine device. Additionally, the World Health Organization has updated its guidelines to provide the practitioner with evidence-based recommendations to assist in selecting the most appropriate contraceptive method for each patient.
