IUI stands for an intrauterine insemination. It’s also sometimes called donor insemination, or artificial insemination. IUI works by placing sperm cells directly into female uterus through vagina around the time of ovulating, helping the sperm get closer to egg. This reduces  time and distance sperm has to travel, making it easier to fertilize the egg.

Before having the intrauterine insemination procedure, female may take fertility medicines that stimulate ovulation. Semen is collected from male partner or a donor in case of donar IUI. It goes through a process called “sperm washing” which collects a concentrated amount of healthy sperm from the semen.

Then your doctor puts the sperm right into females uterus using a catheter. Pregnancy happens if sperm fertilizes the egg and the fertilized egg implants in the lining of the uterus.

IUI is a simple and low-tech procedure, and it can be less expensive than other types of fertility treatments in artificial insemination . It increases the chances of pregnancy in infertility couples, but everyone’s body is different, so ratio will be different.
