A randomized comparison of the Ypsilon-Y and Lippes loop D intrauterine devices in parous women.
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.
