ObjectiveTo evaluate the correlation between endometrial cavity length and expulsion rate in acceptors of the TCu380A intrauterine device (IUD) or the levonorgestrel-releasing intrauterine system (LNG-IUS).MethodsThe study included 235 nulligravida and parous women who received a TCu380A IUD or LNG-IUS and who were observed for up to 1 year. The length of the uterine cavity was measured by uterine sounding and ultrasonography.ResultsThe endometrial cavity was shorter than 3.2 cm in 2 LNG-IUS users and at least 3.2 cm long in 87 LNG-IUS users, with expulsions occurring in 0 (0.0%) and 2 (2.3%) of these women, respectively (P > 0.999). Among the TCu380A IUD users, the endometrial cavity was shorter than 3.6 cm in 63 women and at least 3.6 cm long in 83 women, with expulsions occurring in 3 (4.8%) and 5 (6.0%) of these women, respectively (P > 0.999). The mean length of the endometrial cavity—evaluated via ultrasonography—among the 10 women whose devices were expelled was 3.9 ± 0.3 cm, compared with 3.9 ± 0.0 cm in those who retained their devices (P = 0.799).ConclusionThe present results do not support the hypothesis of an association between uterine length and risk of intrauterine contraceptive expulsion.
