Q: Intrauterine Insemination (IUI) works best in patients...

  1. Where the female has severe endometriosis
  2. Where the male produces few sperm with abnormalities
  3. Where the female has fallopian tube disease
  4. Where the male cannot ejaculate effectively
The success of Intrauterine Insemination (IUI) will vary depending on the underlying cause of the infertility. IUI works best in patients with unexplained infertility, women with a cervix that limits the passage of sperm, and men who are unable to ejaculate effectively. For example, for unexplained infertility, the pregnancy rate with IUI is double that over no treatment.

IUI does not work as well for men who produce few sperm or have severe abnormalities with their sperm and does not help women who have severe fallopian tube disease, moderate to severe endometriosis, or a history of pelvic (lower belly) infections. Other fertility treatments are better for these patients. Overall, if inseminations are performed every month with fresh or frozen sperm, success rates can be better. The success rates depend on whether fertility medications are used, age of the woman, and infertility diagnosis, as well as other factors.
