IUI stands for in intrauterine insemination. It’s also sometimes called donor insemination, alternative insemination, or artificial insemination. IUI works by putting sperm cells directly into your uterus around the time you’re ovulating, helping the sperm get closer to your egg. This cuts down on the time and distance sperm has to travel, making it easier to fertilize your egg.
Before having the insemination procedure, you may take fertility medicines that stimulate ovulation. Semen is collected from your partner or a donor. It goes through a process called “sperm washing” that collects a concentrated amount of healthy sperm from the semen.
Then your doctor puts the sperm right into your uterus. Pregnancy happens if sperm fertilizes your egg, and the fertilized egg implants in the lining of your uterus.
IUI is a simple and low-tech procedure, and it can be less expensive than other types of fertility treatments.
