what is an iui procedure
Intrauterine insemination (IUI): Uses Risks and Success Rate. Intrauterine insemination (IUI) is a fertility treatment that involves placing sperm inside a womanâs uterus to facilitate fertilization. The goal of IUI is to increase the number of sperm that reach the fallopian tubes and subsequently increase the chance of fertilization. IUI provides the sperm an advantage by giving it a head start, but still requires a sperm to reach and fertilize the egg on its own.
