In an intrauterine insemination (IUI) procedure, specially prepared ("washed") sperm is inserted directly into the uterus through a thin, flexible catheter. If you choose this method, your doctor might recommend that you take fertility drugs to increase the chances of fertilization.

IUI is often used when men have slow-moving sperm, lower quality sperm, or a low sperm count. It can also help women who have produced antibodies to their partners' sperm or whose cervical mucus is too scant, acidic, or thick to transport the sperm to the egg. IUI can also be completed with donor sperm.

Success Rates: It depends on maternal age and the quality of sperm. In general, there's a 5 to 20 percent chance of conception per cycle, with your chances increasing each cycle.

Pros: The simple procedure can be performed in a doctor's office.

Cons: IUI can result in multiple births (twins, triplets, etc.). Women may also experience side effects from the fertility drugs.
