Intrauterine insemination (IUI) — a type of artificial insemination — is a procedure  for treating infertility. Sperm that have been washed and concentrated are placed  directly in your uterus around the time your ovary releases one or more eggs to be  fertilized. 

Intrauterine insemination is a relatively low-risk treatment that can be a wonderful option  for many women or couples trying to conceive.
