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. The most common complication of ART is multiple fetuses.
Success rates for assisted reproductive technology vary and depend on many factors. Some things 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
The U.S. Centers for Disease Prevention (CDC) collects success rates on ART for some fertility clinics. According to the 2003 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
ART can be expensive and time-consuming. Many states are starting to mandate coverage. For information regarding insurance coverage, please visit the page infertility Insurance

The most common type of ART is in vitro fertilization (IVF). IVF and other types of ART are presented below.
In vitro fertilization (IVF) where fertilization outside of the woman's body. IVF is the most effective ART. It is often used when a woman's fallopian tubes are
blocked or when a man produces too few sperm. Doctors treat the woman with a drug that causes the ovaries to produce multiple eggs. During IVF, eggs removed from your ovaries are fertilized with sperm (from
your partner or a donor) in a laboratory. After 3 to 5 days, the resulting embryos are placed in your uterus.
• Side effects: You may need to take fertility drugs before the procedure, which will raise your risk of having multiples and of developing ovarian hyperstimulation syndrome (OHSS).
Plus, if you use your partner's sperm, he'll have to provide a sample on demand.
• Success rates: Between 28 and 35 percent of women who try in vitro fertilization conceive.
• Cost: This procedure usually costs between $8,000 and $15,000.
Gamete intrafallopian transfer (GIFT) involves collecting eggs from the ovaries, then placing them into a thin flexible tube with the sperm. The mixture is surgically
injected into your fallopian tubes so fertilization can occur naturally inside your body.
• Side effects: This procedure has a longer recovery time than IVF. You may feel temporary discomfort in your chest and shoulders from the carbon dioxide used during surgery. Also,
you may need to take fertility drugs before the procedure, which will raise your risk of having multiples and of developing ovarian hyperstimulation syndrome (OHSS). Plus, if you use your partner's sperm,
he'll have to provide a sample on demand.
• Success rates: About 25 to 30 percent of women who try GIFT conceive.
• Cost: This procedure usually costs between $8,000 and $15,000.
Zygote intrafallopian transfer (ZIFT)
As with GIFT, your eggs and sperm are mixed together in a lab. But during zygote intrafallopian transfer (ZIFT), your doctor makes sure your eggs are fertilized before surgically placing
them in your fallopian tubes.
• Side effects: This procedure is similar to a cycle of GIFT, but you'll spend more time waiting on the lab. You may feel temporary discomfort in your chest and shoulders from the
carbon dioxide used during surgery. Also, you may need to take fertility drugs before the procedure, which will raise your risk of having multiples and of developing ovarian hyperstimulation syndrome (OHSS).
Plus, if you use your partner's sperm, he'll have to provide a sample on demand.
• Success rates: About 25 to 30 percent of women who try ZIFT conceive.
• Cost: This procedure usually costs between $8,000 and $15,000.
Zygote intrafallopian transfer (ZIFT) or Tubal Embryo Transfer is similar to IVF. Fertilization occurs in the laboratory. Zygote intrafallopian transfer (ZIFT),
combines IVF and GIFT. The eggs and sperm are mixed outside of the body. The fertilized eggs (zygotes) are then injected into the woman's fallopian tubes, where fertilization takes place.
Intracytoplasmic sperm injection (ICSI) involves the injection of a single sperm into a mature egg. The fertilized egg is then placed in the woman's uterus or fallopian
tube. Used with in vitro fertilization, ICSI is often a successful treatment for men with impaired sperm.
• Side effects: Your partner's sperm may need to be drawn from his testicle with a microscopic needle or surgical biopsy — but it's less painful than it sounds.
• Success rates: About 35 percent of couples who try ICSI conceive.
• Cost: ICSI can cost anywhere from $10,000 to $17,000. |
