Whether an IUI is successful varies greatly depending on the underlying cause of infertility, the age of our patient, and her response to fertility medications. IUI works best in patients with unexplained infertility, producing almost double the pregnancy rate over no treatment.
IUI doesn’t work very well for men with low sperm production or who have slight abnormalities in their sperm. Women who have severe fallopian tube problems, moderate to severe endometriosis, or a history of pelvic (lower belly) infections will mot likely see better success with In Vitro Fertilization (IVF).
Chances at success increase with each IUI attempt.
