| Abstract: | Two copper IUDs—the Multiload 375 and TCu380A—are being studied in a randomized multicentre study in parous women involving nineteen centres in nine countries. There have been 1,832 insertions of the Multiload 375 and 1,823 of the TCu380A. After three years of use, the Multiload 375 had a pregnancy rate that was significantly higher than the TCu380A (2.9 ± 0.4 vs. 1.6 ± 0.3 per 100 women). There were no differences at one, two and three years of use in the expulsion rates. It is concluded that the Multiload 375 shows no clinical advantages over the TCu380A and its extra cost should be an important consideration in the choice of the most appropriate IUD. |
