Intrauterine contraception in adolescent women. The GyneFix intrauterine implant.

Pregnancy rates among adolescents have not decreased over the last 10 years, despite numerous efforts. To solve this important health problem, the major strategy recommended is to encourage contraceptive use among sexually active teenagers. An important means of obtaining this is by promoting methods that are not dependent on daily administration in order to avoid noncompliance. One such method (Norplant) has already shown to be much more effective than the combination pill in preventing pregnancy in adolescent women. The frameless intrauterine implant system (fixed, frameless, and completely flexible) has been studied since 1985 in women between 14 and 50 years of age. The results in young nulligravid women confirm its very high effectiveness (cumulative pregnancy rate at 36 months: 1.4%), its low expulsion rate (cumulative rate at 36 months: 0.9%) and its optimal tolerance (cumulative removal rate for medical reasons at 36 months: 2.4%), resulting in a high acceptance of the implant and a high continued use. The system (GyneFix) offers long-term protection (5 years), and its insertion, with or without anesthetic, is easily accomplished in the office. The GyneFix should therefore be recommended as an excellent alternative for birth control pills for young women with low risk for STDs, especially when compliance is a problem, without an increased risk for complications and without systemic side effects. Removal of the device is accomplished by traction on the tail. It can also be used for emergency contraception and for insertion immediately after termination of pregnancy.
