Intrauterine insemination is a relatively simple and safe procedure, and the risk of serious complications is low. Risks include:

  • Infection. Studies indicate that fewer than 1 percent of women experience infection as a result of the procedure.
  • Spotting. Sometimes the process of placing the catheter in the uterus can cause a small amount of vaginal bleeding. This does not usually have an effect on the chance of pregnancy.
  • Multiple pregnancy. IUI itself is not associated with an increased risk of a multiple pregnancy — twins, triplets or more. However, when coordinated with ovulation-inducing medications, the risk of a multiple pregnancy increases significantly. A multiple pregnancy has higher risks than a single pregnancy does, including early labor and low birth weight.
