title: A comparative evaluation of three IUDs.
abstract: Private practice clinical experience with the insertion of 3 types of IUDs (Lippes loop, Dalkon shield, Cu 7) is evaluated.  Life table analyses indicated similar pregnancy rates for the 3 IUDs.  Lower expulsion rates were experienced with the Dalkon shield.  Higher removal rates were experienced for pelvic inflammatory disease and pain and/or bleeding with the Cu 7.  In part, the higher Cu 7 removal rates reflect a change to more liberal indications for IUD removal.
