An intrauterine insemination (IUI) is quick, taking about five to 10 minutes. In most instances the IUI is pretty painless, potentially causing mild cramping, but it generally isn't more uncomfortable than a Pap smear. (In some instances, women find the cramping can be severe.)
Immediately after the procedure, the woman lies on her back for approximately 20 minutes. Then, even though potentially a life-altering event has occurred, she can get dressed and get back to her routine. Some doctors suggest taking it a bit easy for the rest of the day.
