IVF success rates are available online at the website for the Center for Disease Control (CDC) and the Society for Assisted Reproductive Technology (SART). You can look up the national rates, or find rates for individual clinics, at these sites.

The success rates are generally reported according to the woman's age since as a woman gets older, the IVF success rates go down if she's using her own eggs.

According to the data collected for 2014, these are the IVF success rates nationally, when using non-donor eggs, per egg retrieval. (These are not per cycle. In other words, these are the odds of a live birth after one egg retrieval, which may mean conception with fresh eggs/embryos in the cycle of the egg retrieval ​or after a frozen embryo transfer cycle in the following months.)

Live Births per Egg Retrieval:

  • For women younger than 35, the percentage of live births per egg retrieval is 54.4 percent.
  • For women ages 35 to 37, the percentage of live births per egg retrieval is 42 percent.
  • For women ages 38 to 40, the percentage of live births per egg retrieval is 26.6 percent.
  • For women ages 41 to 42, the percentage of live births per egg retrieval is 13.3 percent.
  • For women ages 43 and up, the percentage of live births per egg retrieval is 3.9 percent.

As you can see, IVF success goes down significantly after age 40. For this reason, most women 40 and up use donor eggs.

Success rates when using donor eggs are not as dependent on the woman's age.

Getting Personal Odds for Success With IVF

IVF success is dependent on a number of factors, some of which you have little control over, and many of which are specific to you personally. Some of these factors include your age, the reasons for infertility, whether or not donor eggs (or sperm) will be used, and the competency of the Delhi IVF clinic or lab.

While looking at the national statistics can give you a general idea, it's not going to really tell you what your particular chances of success are.

The great news is that SART has created a patient predictor tool that will give you slightly more personal odds. It's free and easy to use. The tool assumes you have not done IVF before.

You need to provide your age, height and weight, how many pregnancies you've had (this total includes any pregnancy losses), how many full-term births, your cause for infertility, and whether you plan to use your own eggs. (If you don't know your cause for infertility, you can indicate that on their tool.)

Univfy has developed a tool that can give you a better idea of whether IVF will work for you personally. This tool is not free, but it considers more data than the SART predictor and can be used if you have done IVF previously.

You input your personal fertility data, including diagnosis, age, weight, and previous success (or not) in fertility treatments. Their calculator will then consider your data with the research and give you personal odds of statistics.

The calculation is not free but may be worth it. At the end of the day, only you can decide what odds you're comfortable with. What Univfy will give you is more accurate odds to make that decision on.

IVF Success at Individual Clinics

You can look up IVF success rates on individual clinics—and you should—but it's important to take some of this information with a grain of salt.

For example, a clinic with excellent rates may be turning away couples who have a lower chance of success. Or, they may be transferring a higher number of embryos per treatment cycle, which is risky. It's also possible that a very small client base can show abnormally high success rates.

Also, make sure you're comparing their live birth rates and not just their pregnancy rates. Pregnancy success is going to be higher than the live birth rate since it does not account for miscarriage and stillbirth.
