What is intrauterine insemination (IUI)?

Intrauterine insemination (IUI), a form of artificial insemination, is a relatively simple procedure that enables conception by directing sperm to the right place at the right time.

In this process, a thin tube called a catheter is placed directly into the cervix, and a carefully prepared sperm sample is injected directly through the catheter into the womb.

IUI increases a woman’s chances of becoming pregnant by injecting an optimal sperm sample directly into the uterus at a time when the woman is most fertile.

Studies have shown that pregnancy is more likely to occur if timing of exposure to sperm is controlled in this way, and if sperm is placed in higher numbers closer to the egg or eggs.

When is IUI recommended?

  • IUI is often recommended for women or couples who:
  • Have ovulation problems and are undergoing ovulation induction, especially when timed intercourse has not succeeded
  • Are unable to have appropriately timed intercourse due to travel problems or in cases of sexual dysfunction
  • Encounter mild male infertility
  • Have unexplained infertility
  • Are women using donor sperm
  • Have been unsuccessful with infertility medication alone or with other treatments
