“…However, asymptomatic IUD displacements are only detected, if regular sonographic controls of the IUD position are performed. Previous expulsion of an IUD, young age, hypermenorrhea, nulliparity and uterus sounding 9.0 cm are associated with a higher rate of IUD dislocations [2,6,7]. Most downward migrations of IUD are thought to occur within 6 weeks after insertion [8].…”

Objective: The contraceptive efficacy of intrauterine devices (IUD) is thought to relate to the position of the IUD in the uterine cavity. Several trials examined the number of copper IUD expulsions, but none evaluated the partial and complete expulsion rate of the levonorgestrelreleasing device (LNG-IUD).Study design: This retrospective cohort study compares the dislocation rate of the Multiload 375 IUD (ML 375) and the LNG-IUD in 214 women (107 subjects with each IUD). Transvaginal ultrasound was used to monitor the IUD position immediately after insertion, after 6 weeks, and later on at intervals of 6 months. The observation period included 3631 cycles.Results: We detected a significantly lower number of dislocations in LNG-IUD users. Previous expulsion was associated with a significantly higher risk for a re-expulsion in both IUD groups. Hypermenorrhea was not associated with an increased dislocation rate in LNG-IUD users. Conclusion: Expulsions are less likely to occur with the LNG-IUD, which might contribute to its contraceptive efficacy. #

“…16 The study demonstrated that when the difference between uterine cavity length and the maximum length of MLCu375 was 10 mm or greater, the expulsion rate increased significantly (P > 0.01). Our study provided additional evidence on the association of LUC with expulsion or displacement in the Chinese population.…”

“…We categorised women into two groups using 45 mm as the cut-off point of LUC, based on Castro's study, 16 when analysing the effect of LUC among MLCu375 users. However, according to the literature there are no widely accepted cut-off points of LUC for TCu380A, of LTD for either model, and of D1.…”

“…[10][11][12][13][14][15] One hypothesis for IUD expulsion or displacement is dimensional incompatibility between the uterine cavity and the IUD. Castro found that the expulsion rate within 1 and 2 years of MLCu375 was more than four times higher for women with an endometrial cavity length of ≥45 mm, compared with those with a cavity length of <45 mm (P < 0.01) 16 ; however, two prospective studies failed to find any association between endometrial cavity length and the expulsion rate of IUDs. 17,18 The relationship between uterine cavity dimensions and IUD expulsion remains unclear.…”

“…Intrauterine devices (IUDs) are the most widely used reversible method of contraception, particularly in less developed regions such as Africa, Asia (excluding Japan), and Latin America, where 16.5% of women of reproductive age use this device. In contrast, only 9.4% women use IUDs in more developed regions.…”

Objective To evaluate the effect of the dimensions of the uterine cavity in relation to the expulsion, or removal for displacement, of intrauterine devices (IUDs) MLCu375 and TCu380A.Design A case-control study nested in a multicentre clinical trial.Setting Eighteen family planning clinics in China.Population Forty-eight pairs of TCu380A users and 118 pairs of MLCu375 users.Methods The women were classified as cases if IUD expulsion or displacement occurred during the first year of follow-up after insertion. One control was randomly selected for each case matched by IUD model, centre, age, service provider for insertion, and date of insertion. Axial length of the uterine cavity (LUC) and the largest transverse diameter of the coronal section of the uterine cavity (LTD) were measured using abdominal ultrasound. We used multivariate conditional logistic regressions to estimate the adjusted odds ratios (aORs) of expulsions or displacements among women with different sizes of uterine cavity according to the quartile of LUC and LTD, respectively.Results Among MLCu375 users, women with LTD ≥ 27 mm had a higher risk of expulsion or displacement (aOR 2.40; 95% confidence interval, 95% CI, 1.02-5.63), after adjusting for the volume of menstrual flow, dysmenorrhoea, parity, uterine position, MLCu375 type, and LUC. Among TCu380A users, the association between LTD ≥ 37 mm and expulsion or displacement (aOR 4.98; 95% CI 1.01-22.49) was statistically significant, after adjusting for LUC and potential confounding factors.
