Do retroverted uteri adversely affect insertions and performance of IUDs?
A large international multi-center IUD data set (N = 5520) coordinated by Family Health International was analysed to determine if the uterine position of a woman (anteverted, mid-positioned or retroverted) affects the ease of IUD insertion and if knowledge of uterine position would diminish insertion-related problems and improve IUD performance. Findings showed that insertion-related events were rare irrespective of uterine position. Women with retroverted uteri were not associated with higher termination rates for accidental pregnancy, expulsion or removal for bleeding and/or pain after 12 months of IUD use, as compared to the other two uterine position groups. All insertions in this data set were performed by experienced obstetricians/gynecologists, and our findings suggest that women with retroverted uteri should be equally good candidates for IUD contraception.
