Abstract

A randomized single-blind clinical study was performed to determine whether there was any difference in the termination event rates between parous women using the Ypsilon-Y intrauterine device (IUD) and those using the Lippes loop D. A total of 174 women received the Ypsilon-Y IUD and 173 women received the loop D. A significant higher incidence of expulsion occurred with use of the Ypsilon-Y IUD.

摘要

进行了一项随机单盲临床研究，以确定经产妇女使用Ypsilon-Y型宫内节育器（IUD）和使用Lippes D型节育环的终止事件发生率是否存在差异。共有174名妇女接受了Ypsilon-Y型宫内节育器，173名妇女接受了D型节育环。使用Ypsilon-Y型宫内节育器时，排出发生率显著更高。
