Intrauterine insemination (IUI) is a type of artificial insemination. It 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. The hoped-for outcome of intrauterine insemination is for the sperm to swim into the fallopian tube and fertilize a waiting egg, resulting in a normal pregnancy. IUI procedure is performed by IVF Specialists or Gynaecology and Obstetrics.
