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.
本文介绍了一项针对300名使用铜-7宫内节育器的马来西亚女性的研究。2%的使用者未生育。97.7%的病例插入过程轻松，副作用极小。在一项超过4634个女性月的研究中，观察到在使用12个月和24个月时，累积脱落率较低，分别为3.1%和3.6%。然而，在使用12个月和24个月时，累积妊娠率相对较高，分别为4.3%和9.2%。在总共19次妊娠中，有12例发现节育器下移，这一发现并不常见。一名女性在插入节育器五个月后发生移位，在此情况下，通过剖腹手术取出了节育器。本文讨论了该研究的结果及其意义。
