Abstract

PIP: The frequency of IUD expulsion, pregnancy, and removal was studied in 694 users. Those IUD types examined were the Lippes Loop D, Copper T-device, the 220C, and the T releasing 65 mcg of progesterone. A comparison was done as to the length of the uterine cavity, measured by a Hollister device which tends to be very accurate. Other authors have described certain length limits in the uterine cavity beyond which the number of pregnancies, expulsions, and removals are greater, but this was not confirmed in the present study. The only statistically significant difference was reduced frequency of such events in those women using the Copper T as compared with the Lippes Loop, independent of uterine cavity length.
