Intrauterine Insemination (IUI) 

Intrauterine insemination is a procedure in which sperm are washed and injected in to the uterus using a soft plastic catheter.  IUI is frequently confused with IVF because they sound so similar, but the two procedures are very different.

The insemination procedures is done as close to the time of ovulation as possible. It is usually done with partner/husband sperm, but may also be done using donor sperm (also known as TDI). Usually IUI is done in conjunction with stimulation using oral or injectable fertility drugs, but occasionally may be done without the use of medication. Intrauterine insemination is usually painless but may involve discomfort and bleeding, and rarely infection. The IUI procedure itself does not increase the risk of multiple pregnancies but the fertility drugs used with the cycle may.
