Intrauterine contraception using the Copper Mini-Gravigard 7 IUD: summary of 328 case histories

Contracept Deliv Syst. 1981 Apr;2(1):171-6.


PIP: A multicenter study with 328 women, 302 of whom were nulliparous, was carried out using a Copper 7 IUD of reduced size: the Mini-gravigard. 10 Swiss and Austrian gynecologists in private practice participated in the trial. 92% of the patients were nulliparous. Insertion was easy and painless in the majority of the cases. An experience of 3081 women cycles was accumulated. Over the 28-month study, 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 has been performed according to the life-table method.
