A lippes [Loop] type intrauterine device (IUD) was modified to be used for immediate postpartum insertion. In 114 patients in whom the modified IUD was inserted immediately after delivery, expulsion rates at 6 mo. averaged 30%. Expulsion rates were significantly different, at P < 0.05, for women in whom the IUD was inserted digitally (19.5 .+-. 5.6% at 6 mo.) compared to those in whom it was inserted using surgical forceps (39.6 .+-. 7.1%). Expulsion rates were higher for inexperienced inserters (P < 0.01). This modification of an otherwise standard IUD has a continued high expulsion rate. The technique of insertion has significant impact on the likelihood of expulsion.
