What Is Intrauterine Insemination (IUI)? | MFC

Intrauterine insemination (IUI) is an office fertility procedure that aims to raise the odds of pregnancy by placing the healthiest sperm in the upper part of the uterus. After an ejaculate is collected, our Marin lab uses sperm washing to remove the unwanted components of seminal plasma. A small, concentrated volume of sperm is then placed in the uterus via a soft catheter (thin straw-like device).
