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.
