Adolescent girls are very fertile and therefore need a reliable contraceptive strategy in order to prevent unwanted pregnancies.

This article will focus on available IUDs suitable for adolescents and will address misconceptions and barriers to use of IUDs in this age group. We believe this information will encourage physicians in recommending IUD use to adolescents during their most vulnerable years.
