ML Cu250是标准的ML IUD,也是一种最广泛使用的含药IUD。近年来也对含铜较高的MLCu375模型进行了试验。MLCu375提高了避孕能力并发展了MLCu250的有效作用而不影响其他参数,尤其是脱落的危险性。标准的MLCu250和MLCu375模型的特点是二者都有相同的结构但MLCu375铜丝较粗,在这一改良中MLCu375比MLCu250铜的表面积增加了50%,重量增加了82%。我们陆续放置MLCu375于2,422名妇女。5年之间累积84411妇女月,失访率为9.0%。结果说明MLCu375是有效的和安全的,能很好保留于子宫,而且妇女耐受性良好。
The ML Cu250 is the standard ML IUD and is one of the most widely used medicated IUDs. In recent years, the MLCu375 model with higher copper has also been tested. MLCu375 improves contraceptive ability and develops the effective action of MLCu250 without affecting other parameters, especially the risk of shedding. The standard MLCu250 and MLCu375 models are characterized by the same structure but with thicker MLCu375 copper wire. In this modification, MLCu375 has a 50% increase in surface area and a weight gain of 82% over MLCu250 copper. We placed 2,411 women in MLCu375 one after another. Over the 5 years, a total of 84,411 women were registered, with a rate of 9.0%. The results show that MLCu375 is effective and safe, well retained in the uterus, and that women are well tolerated.
