Abstract
According to Dr. Tatum H. J., et al.: the incidence of spontaneous abortion more than doubled when the IUD remained in utero. The chance of a livebirth being premature was four times greater when the IUD remained in situ that when it was removed. Besides, a certain number of authors have tried their best to remove IUDs in early pregnancies before suction curretage, and they can't follow up after D & C. So the policy at our hospital, in cases where a woman wishes to continue a pregnancy that has occurred with an IUD in situ, is to remove IUD as soon as possible.
