The ML Cu250; clinical experience in Belgium and The Netherlands

The ML Cu250, a copper-wired intrauterine contraceptive device, was inserted in 5736 women, at interval or immediately after delivery of the placenta. Forty-eight months after insertion, the data covering 196 214 woman-months were computerized and then analysed according to the life-table method. Interval insertion was more effective than postplacental insertion. In nulligravidas interval insertion did not increase the removal rates for other medical reasons (including pelvic inflammatory disease), but expulsion rates were higher relative to the entire group (a variety of parities).
