A multicenter study with 328 women, 302 of whom were nulliparous, was carried out using a Copper 7 intrauterine device of reduced size: the Mini-Gravigard. Ten Swiss and Austrian gynecologists in private practice participated in the trial. Ninety-two percent of the patients were nulliparous. Insertion was easy and painless in the majority of cases. An experience of 3081 women cycles was accumulated. Over the 28 mo. study period, 5 involuntary pregnancies were recorded (Pearl Index = 2). The percentage of spontaneous expulsions was 4.9% (16 cases of partial or complete expulsion). In 7.6% of all women (25 cases), the device was removed due to pelvic pain and persistent bleeding. An evaluation of these results was performed according to the life-table method.
