title: Contraceptive implants.
abstract: Available contraceptive implants appeal to women of diverse cultural and socioeconomic background because they offer long-term contraception, safety, effectiveness, reversibility and lack of estrogenic side-effects. Experience with Norplant I indicates that despite some side-effects the continuation rate is the highest for any reversible method of contraception. Disruption of the menstrual cycle is the main reason for discontinuation, hence research effort needs to focus on the mechanism of progestogen-induced endometrial bleeding and appropriate therapy. Implant service programs should have trained and skilled personnel who can provide adequate counseling that complements any public education effort and also provides effective services. Because contraceptive implants offer no protection against sexually transmitted infections, those who engage in high-risk sexual behavior should be encouraged to use condoms as well.
