Does the IUD increase the risk of ectopic pregnancy?
IUDs do not increase the risk of ectopic pregnancy. The IUD protects against all pregnancies, including tubal implantation or ectopic pregnancies. IUD users are therefore less likely to experience an ectopic pregnancy than sexually active women using no contraceptive method. In the unlikely event of pregnancy in an IUD user, that pregnancy is more likely to be ectopic than would be a pregnancy in a non-user. Still, pregnancy for an IUD user is far more likely to be normal than ectopic: only an estimated one in every 13 to 16 pregnancies, or six percent to eight percent, is ectopic.
