Assisted Reproductive Technology

Also called: ART, IVF, In Vitro Fertilization

Assisted reproductive technology (ART) is used to treat infertility. It includes fertility treatments that handle both a woman's egg and a man's sperm. It works by removing eggs from a woman's body. The eggs are then mixed with sperm to make embryos. The embryos are then put back in the woman's body. In vitro fertilization (IVF) is the most common and effective type of ART.

ART procedures sometimes use donor eggs, donor sperm, or previously frozen embryos. It may also involve a surrogate or gestational carrier. A surrogate is a woman who becomes pregnant with sperm from the male partner of the couple. A gestational carrier becomes pregnant with an egg from the female partner and the sperm from the male partner.

The most common complication of ART is a multiple pregnancy. It can be prevented or minimized by limiting the number of embryos that are put into the woman's body.

Female Infertility

Infertility means not being able to get pregnant after at least one year of trying (or 6 months if the woman is over age 35). If a woman keeps having miscarriages, it is also called infertility. Female infertility can result from age, physical problems, hormone problems, and lifestyle or environmental factors.

Most cases of infertility in women result from problems with producing eggs. In premature ovarian failure, the ovaries stop functioning before natural menopause. In polycystic ovary syndrome (PCOS), the ovaries may not release an egg regularly or they may not release a healthy egg.

About a third of the time, infertility is because of a problem with the woman. One third of the time, it is a problem with the man. Sometimes no cause can be found.

If you think you might be infertile, see your doctor. There are tests that may tell if you have fertility problems. When it is possible to find the cause, treatments may include medicines, surgery, or assisted reproductive technologies. Happily, many couples treated for infertility are able to have babies.
