“…There are two other explanations for the different results. First, in our study, the number of dislocations is higher for both IUD types, because using transvaginal ultrasound, we did not only identify complete expulsions, but although partial expulsions [15,17,18]. This assumption is supported by the results of Petta et al [3], who performed a sonographic follow-up of 235 women with a CuT 380Ag for 12 months.…”

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. #

“…Bahamondes L et al, Batár I et al and Jenabi E et al also reported the similar findings. [22][23][24] In multiple studies bleeding and dysmenorrhea led to CuT380A removal in 4% and 15% women respectively over 1 year of its use. 25 Pain and bleeding were cause for removal in 5% women in a multinational study conducted in Yugoslavia and Panama .…”

Background: The Study was planned to evaluate and compare the expulsion and continuation rates of post placental insertion of Cu 375 and CuT380A in Indian women at Safdarjung Hospital New Delhi, after approval was obtained from Institutional Ethical committee.Methods: Study group consisted of 300 women, divided into two groups: Group A and Group B. The data was analysed by using ‘student “t” test/ non-parametric ‘Wilcoxon Mann Whitney’ for quantitative variables to evaluate the safety, efficacy and acceptability.Results: Mean age was 24.99 years (range: 19-35years), All women were married (off which 64% literate) and Mean parity in group A was 1.97 and 2.06 in group B. Mean pain score during intrauterine contraceptive device (IUCD) insertion on visual analogue scale was 2.93 in group A and 3 in group B and was not statistically different. 84% women completed 12 months follow up in group A and 83.33% women in group B. Strings were visible in 74% women in group A and in 34% women in group B at 1 month of IUCD insertion. Visibility of strings increased in successive follow up visits and was visible in >80% of women at the end of one year in the both groups. String visibility after intra-Caesarean insertion was delayed. Fifty one percent (n=77) subjects in group A and 54% (n=81) in group B experienced amenorrhea up to six months. Menorrhagia was reported in 7.33% in group A and women 8.66% in group B at the end of 1 year of follow up. Pain was complained by 26 out of 150 (17.3%) women in group A as compared to 36 out of 150 (24%) women in group B after 1 month of insertion. There was no case of PID in group A whereas there were 3 cases of PID in group B. There was no perforation/trauma and pregnancy in either group.Conclusions: Overall expulsion rate was 13% and removal rate was 5% in our study. Continuation rate was 83.3% in Cu 375 and 80.6% in CuT380A at 12 months. There was no significant difference between the IUCDs regarding the safety, efficacy and complications such as expulsion, bleeding etc.

“…The pregnancy rate in the present study of the Nova-T ® 380 of 0.8 shows no clear improvement. Neither does the pregnancy rate of 0.5 at 12 months obtained in the study by Batar et al 6 show a clear improvement. The increased surface area of copper was not associated with a reduced pregnancy rate, but as this was not a direct comparative study with the Nova-T ® , the influence of the increased area of copper must remain somewhat uncertain.…”

Doctors working in general practice and at family planning clinics throughout the UK who collaborate in the UK Family Planning and Reproductive Health Research Network were responsible for the fitting of 572 Nova-T®380 intra-uterine contraceptive devices (IUDs). The Nova-T® (and formerly the identical Novagard®) IUDs have copper with a surface area of 200 mm2. The device used in this study, the Nova-T®380, has copper with a surface area of 380 mm2. The purpose of the study was to evaluate the pregnancy and complication rates of this new device, with its increased area of copper, in comparison with other published results, in the clinical setting of British general practice and family planning clinics. The 12-month cumulative life-table event rates were: pregnancy 0.8, expulsion 5.6, removal for bleeding or bleeding and pain 11.0. The continuation rate was 73.4. The pregnancy rate at 12 months showed good contraceptive performance. The increased surface area of copper was not associated with a reduced pregnancy rate, but as this was not a direct comparative study with the Nova-T®, the influence of the increased area of copper must remain somewhat uncertain. This study found the discontinuation rate for bleeding problems and pain with bleeding to be higher than in other published studies. Other event rates were consistent with other published studies.
