The baby will be deformed if born to a woman with an IUD in place. IUDs do not cause deformities in babies. At delivery, the IUD is usually found on the maternal side of the membranes or placenta but never within the amniotic sac. The IUD and coil are different methods of birth control. In dealing with these misconceptions, it will be helpful to review what the IUD is and how it is inserted.
Most intrauterine devices are flexible plastic devices which are placed within the uterus.
They come in many shapes and sizes. They are called IUDs. An instrument called an insertion guide is used during the procedure. Just prior to the insertion, the IUD is drawn up inside the guide. The guide is relatively rigid and is about the size of a soda straw.
