Follow-up of intrauterine contraceptive devices

The intrauterine contraceptive device (IUCD) is the most popular, reversible contraceptive method, worldwide. Leaving an IUCD in-utero even beyond the time recommended by the manufacturer has been found both safe, and effective in terms of contraceptive ability. In 1995 we screened the medical records of the gynecologic infirmaries of 4 agricultural settlements (kibbutzim) and found 78 women who had worn an IUCD continuously for more than 5 years. All had been regularly examined every 6 months. Most of the IUCDs (63, 80.7%) were copper-containing. Mean IUCD wear was 7.9+/- 2.6 years (range, 5-17 years). At the time of the study, 38 (48.7%) of the IUCDs were still in utero. Related complications were 3 cases of dysmenorrhea (3.8%) and 20 of metrorrhagia. No pregnancies or pelvic infections were recorded. This study also shows that wearing an IUCD beyond the time recommended by the manufacturer is not associated with loss of contraceptive effectiveness. Furthermore, the rate of IUCD-related complications after 5 years of wear was not higher than during the first 5 years. To support these findings further studies with larger samples are needed.
