Does the IUS increase the risk of ectopic pregnancy?
The IUS (Intra Uterine System) is not associated with any increased risk of ectopic pregnancy and the rate is lower than the rate for women aged 25-40 years who are not using any method of birth control. No method of contraception can totally exclude the possibility of an ectopic pregnancy but the IUS user is at a very low risk. (0.6 cases per 1,000 woman-years of use).
