What is IUI?

Intrauterine insemination (IUI), also known as artificial insemination, involves the direct injection of retrieved sperm into the uterus using a special catheter. The sperm used in IUI will still need to travel to the egg for fertilization, so it is best used with mature sperm — sperm that are mobile and able to find and penetrate an egg. Vasal sperm is best-suited for this assisted reproduction technique. It may take several IUI injection cycles to achieve pregnancy, and IUI is generally less effective than IVF, with only a 4% to 5% success rate with each IUI cycle. Fertility drugs can increase the IUI pregnancy success rate up to 16%.
