Artificial insemination (also called IUI or intrauterine insemination) is a procedure that involves washing sperm, then introducing the healthiest specimens into the woman's uterus with a catheter. It is often recommended if a man has erectile dysfunction, a low sperm count, or low sperm motility. IUI can help you get pregnant if your cervical mucus doesn't allow sperm to pass through easily or if you have endometriosis, cervical scarring, a semen allergy, or unexplained fertility problems.nn
