Demystifying Fertility Success Rates: How Are They Determined?
Posted by: Editor on Oct 18, 2010 in News

At CNY Fertility Center, we are proud of our success rates and we want you to understand how they are calculated. Not all fertility clinics use the same treatment approaches and not all clinics calculate success rates in the same manner, which can make results quite misleading. To determine whether your chosen clinic has good success rates, it’s a good idea to compare them with the national averages as well as with some of the more successful clinics.

SART (The Society for Assisted Reproductive Technology), sets the standards for the measurement of fertility success rates and publishes them on their website. The following are the criteria that are often used to determine fertility success rates of specific clinics:

Total IVF Cycles Per Year
This gives an indication that the clinic routinely and consistently performs IVF cycles, whether or not they result in birth. According to SART, anything over 120 per year is good.

Fresh Embryos From Non-Donor Oocytes
These figures look at couples who engaged in IVF using a fresh cycle, where the ovaries are inseminated in the laboratory and then placed back into the uterus. These do not include frozen eggs.

Percentage of Transfers Resulting in Live Births
This statistic represents a true measure of a fertility clinics success. This is the most important number to look at as it describes the cycles with transfers that actually resulted in live births. Sometimes, there is an egg retrieval but no transfer of the embryo or the IVF gets canceled for whatever reason.

What About Age Group?
The age groups at which fertility clinics get success from are of utmost importance. In women younger than 35 years of age there is the greatest chance of success and f ages 35-37 there is still a statistically favorable chance. Success in the age group of 38-40 years would show some real talent in a fertility clinic. So, look at the number of cycles performed in this segment to get an idea of success. The over 41-year old age group is a more challenging group that often involves egg donation, but many clinics still try IVF procedures at this age.
