Objective To investigate the clinical application of MYCu intrauterin econtraceptive device (IUD) and TCu220C intrauterine device (TCu220CIUD). Methods The women of childbearing age who were asked to place IUD contraception in Jiading Central Hospital were randomly assigned to receive 150 cases of MYCuIUD and TCu220CIUD respectively and were followed up regularly for 1, 3, 6 and 12 months after placement. Results When placed for 12 months, the cumulative pregnancy rates of MYCuIUD group and TCu220CIUD group were 0.67 per 100 woman-years, and the cumulative exfoliation rates were 0.67 per 100 women, 2.00 per 100 women, respectively. Because of adverse reactions (P> 0.05). The rates of recuperation were 96.00 per 100 woman women, 92.30 women per 100 women, and 4 follow-up rates were 2.01 per 100 women year and 4.14 per hundred women year respectively The prevalence of chief complaint was lower in the MYCuIUD group than in the TCu220CIUD group (P <0.05). The most common adverse reactions in the complaint were bleeding and pain. Conclusion MYCuIUD has good anti-fertility effect, low exfoliation rate and small adverse reaction after device placement, which is an ideal IUD. It is worth further promotion and application.
