Intrauterine insemination (IUI) is another type of treatment for infertility. IUI is known by most people as artificial insemination. In this procedure, the woman is injected with specially prepared sperm. Sometimes the woman is also treated with medicines that stimulate ovulation before IUI.

IUI is often used to treat:

    * mild male factor infertility
    * women who have problems with their cervical mucus
    * couples with unexplained infertility

Assisted reproductive technology (ART) is a term that describes several different methods used to help infertile couples. ART involves removing eggs from a woman's body, mixing them with sperm in the laboratory and putting the embryos back into a woman's body. ART can be expensive and time-consuming.

Success rates vary and depend on many factors. Some factors that affect the success rate of ART include:

    * age of the partners
    * reason for infertility
    * clinic
    * type of ART
    * if the egg is fresh or frozen
    * if the embryo is fresh or frozen

According to the 2003 U.S. Centers for Disease Prevention (CDC) report on ART, the average percentage of ART cycles that led to a healthy baby were as follows:

    * 37.3% in women under the age of 35
    * 30.2% in women aged 35-37
    * 20.2% in women aged 37-40
    * 11.0% in women aged 41-42
