Evaluation of copper-7 intrauterine device in Malaysian women.

A study of 300 Malaysian women who were fitted with the Copper-7 intrauterine device is presented. Two per cent of the acceptors were nulliparous. Insertion was easy in 97-7% of the cases and the side effects were minimal. In a study of over 4,634 women-months a low cumulative expulsion rate, at 12 and 24 months of use, of 3-1 and 3-6 respectively, was observed. However, relatively high cumulative rates of pregnancy of 4-3 and 9-2 occurred at 12 and 24 months of use respectively. Out of a total of 19 pregnancies, in 12 cases the device was found to have descended, a finding not commonly reported. One woman experienced translocation of the device five months after insertion, and in this instance, the device was removed by laparotomy. The findings in this study and their implications are discussed.
