Performing artificial insemination (IUI) is actually minimal risk, but even so there are some risks for some women including the risk of being pregnant with twins, ovarian hyperstimulation syndrome, and infection.
Intrauterine insemination is a simple process and is considered one of the least invasive methods. The side effects associated with the process are also very minimal. Most of the side effects of IUI treatment usually subside over time or go away after stopping fertility drugs.
