Ectopic pregnancy among past IUD users.
The relationship between return to fertility and pregnancy outcome in women with IUD removal for planned pregnancy as well as the frequency of ectopic pregnancy among all former IUD users in comparison with the general population was studied. The cumulative conception rate in the group of women with IUD removal for planned pregnancy (n = 748) was 93.7% after 5 years, 93.4% being intrauterine and 0.3% ectopic. Rates of ectopic pregnancy in women with IUD removed for planned pregnancy were 2.7/1000 women, 3.6/1000 deliveries and 2.9/1000 pregnancies vs. 3.9, 13.4 and 5.6 in the general population. Only when the number of deliveries is used as denominator, have these differences reached statistical significance (P less than 0.05). Except for bleeding/pain and PID removals (6.0 vs. 3.9), in all other groups of former IUD users the incidence of ectopic pregnancy was also lower than in the control group. From the results of this study it was concluded that former IUD users are not at an increased risk for ectopic pregnancy.
