IVF Statistics Revealed
Have you made the decision to undergo in vitro fertilization (IVF)? If so, perhaps the first question you have asked yourself is “what are success rates with IVF?" Here we explain what you should know about IVF statistics. After all, when it comes to an expensive, intense process like in vitro fertilization, it is helpful to know all the facts.
IVF statistics by age
Below, we share in vitro fertilization statistics from 2011. This shows the percentage of women, by age group, that gave birth after an embryo transfer and IVF procedure. The first group of IVF statistics below shows the percent of women who gave birth after IVF transfer with fresh embryos. The second group shows IVF statistics for women that used thawed frozen embryos for the transfer. As you can see in the below IVF statistics, as women age, success rates with IVF tend to decrease.
IVF success rates with fresh embryos
- Women under 35: 46.3 %
- Women 35-37: 38.4 %
- Women 38-40: 27.5 %
- Women 41-42: 16.6 %
- Women 42: 6.5 %
IVF success rates with frozen embryos
- Women under 35: 39.3 %
- Women 35-37: 35.7 %
- Women 38-40: 30.3 %
- Women 41-42: 24.5 %
- Women 42: 16.5 %
IVF statistics and a single IVF cycle
When reviewing IVF statistics, it is important to remember that these statistics do not necessarily show how many women got pregnant during their first IVF cycle. Rather, IVF statistics show how many women got pregnant during a single IVF cycle. There is no way of knowing whether it was their first, second or third cycle, and so on.
In vitro fertilization statistics reveal that the average couple has the best chances of success when they commit to trying at least two to three IVF cycles.

IVF statistics using donor eggs
Some women will be unable or unlikely to conceive with IVF using their own eggs, for a number of reasons. In this situation, the use of donor eggs may increase the chances of success with IVF. In recent years, about ten percent of all assisted reproductive technology (ART) cycles used donor eggs.
One of the benefits to using donor eggs with IVF is that age becomes a less important factor when using donor eggs. There is approximately a 55 percent live birth rate when using fresh embryos from donor eggs. When using frozen embryos, 2011 IVF statistics show the live birth rate is about 36 percent.
IVF statistics and birth defects
Recent studies have shown mixed findings regarding birth defects in children conceived through IVF. In general, both naturally conceived children and children born after IVF have around a three to five percent chance of being born with some type of birth defect. Researchers are currently analyzing the data surrounding IVF, children, and birth defects to learn more.
IVF statistics and miscarriage
Studies show that miscarriage rates do not seem to be significantly higher for those using IVF. In vitro fertilization statistics reveal that miscarriage rates do seem to increase as women get older, but this is also true for the general population. Miscarriage rates typically range from about 15 percent for a 20-year-old woman to over 50 percent for women over 40.
IVF statistics and health risks
As with any medical procedure, in vitro fertilization can carry uncomfortable side effects and other health risks. Approximately 30 percent of patients undergoing ovarian stimulation in preparation for IVF experience a mild case of ovarian hyperstimulation syndrome (OHSS). With OHSS, the ovaries become extremely swollen and painful. If you experience any side effects with IVF, let your doctor know.
In addition, there is approximately a five percent chance of ectopic pregnancy with IVF.
Remind yourself that you and your partner are unique individuals. Make an appointment to talk with your fertility specialist and learn all about your situation and IVF. Should you use donor eggs? Are you at an increased risk for side effects or miscarriage? These are important questions to ask your doctor. Your doctor is the best person to explain IVF statistics to you.
IVF statistics bring new hope
As the above IVF statistics reveal, in vitro fertilization can be quite effective in helping couples dealing with infertility conceive. This is especially true for couples that have been diagnosed with infertility problems like blocked or absent tubes, endometriosis, or low sperm count. In vitro fertilization statistics repeatedly show increased success in managing infertility problems and increasing a couple’s chances of conceiving.
Discuss IVF statistics with your fertility specialist. Ask your doctor what your personal chances are for getting pregnant, depending on your age and unique fertility history.Sources
