A clinical study comparing the performance of three IUCDs (Multiload Copper 250, Copper T 200, and Lippes Loop C)

300 Women at Cairo's Al-Zahraa Hospital, using 1 of 3 different IUds (CuT 200, multiload Cu250, and Lippes loop size C) to compare the rate of complications encountered among the 3 groups. Failed insertion was highest among the Cu T200 group with a rate of 3.24/HWY, hundred woman years. Accidental pregnancy was highest among that group as well. With a rate 2.16/HWY compared with 1.10/HWY among the ML Cu250 group and none among the Lippes Loop group. The spontaneous expulsion rate was the same for the Cu T200 and Lippes Loop, i.e., the rate was 4.32/HWY and 4.44/HWY for the 2 groups, respectively, compared with 1.10.HWY for the ML Cu250. The highest removal rate because of pain or bleeding was encountered among the ML Cu250 users, i.e., the rate was 4.41.HWY compared with 3.33/HWY among the Lippes Loop group and 1.08/HWY for the Cu T200 group. The overall failure rate was 8.82/HWY for ML Cu250, 11.89/HWY for Cu T200, and 11.10/HWY for the Lippes Loop group.
