Intrauterine insemination (IUI) is a form of therapeutic insemination (TI) using the husband's (AIH) or donor (AID) sperm. Therapeutic insemination has been used as treatment for infertile couples for many years. More recently, IUI has become an option for many couples prior to considering more complicated and expensive assisted reproductive treatment such as In Vitro Fertilization (IVF).

IUI procedure involves semen collection in the special male room followed by immediate sperm preparation techniques using sperm enhancement of maximum mobile sperms. This washed and prepared sperm is then inseminated via a special catheter directly into uterine cavity. This maximizes the chances of ovulation induction.
