Intrauterine insemination (IUI) is the process of preparing a sperm specimen to concentrate it for the most active motile sperm and placing the washed sperm into the uterus as close as possible to the tubal opening.
Intrauterine insemination is often recommended because studies have shown that pregnancy is more likely to occur if timing of exposure to sperm is controlled, and if sperm is placed in higher numbers closer to the egg or eggs.
IUI is often recommended for women or couples who:
- have ovulation problems and are undergoing ovulation induction;
- are unable to have normal intercourse with ejaculation into the vagina at appropriate times;
- have mild male factor infertility;
- have unexplained infertility;
- have failed other treatments, such as Clomiphene alone.
