Success Rates

Patient pregnancies are the ultimate goal for all of us at the Fertility Center, and we want our patients to be confident in the integrity of our assisted reproduction program. More than 300 babies have been born since 1999 as a result of the efforts of our doctors and embryologists, and some of our patient groups are experiencing pregnancy rates that exceed 70 percent. 

Our clinic is one of only a handful around the country that transfers embryos at the blastocyst stage, which is five days after retrieval and in vitro fertilization. For years, the general practice has been to transfer on day three, but the Fertility Center and other cutting-edge practices are seeing better success rates when embryos are allowed to divide under incubation for an additional two days. By the fifth day, embryos are no longer living off egg reserves, so doctors and embryologists are able to choose the strongest and most viable embryos for transfer. This incredible attention to detail allows for fewer embryos to be transferred while still achieving pregnancy success, which in turn lowers the rate of triplets and helps patients avoid the complications that can be associated with multiples.   

The Society for Assisted Reproductive Technology (www.sart.org) has developed a national database for reporting fertility treatment outcomes which is published by the Centers for Disease Control. The SART report only includes data from IVF treatment and does not include pregnancies from intrauterine insemination, ovulation induction or surgery. While the system assures consistency in reporting clinic outcomes around the country, reporting lags behind the most current data that needs to undergo a rigorous review process. Additionally, each fertility clinic takes a unique approach to assisted reproduction. For example, some clinics will turn away patients with lower conception odds; others let patients decide on their own whether or not to proceed with treatment. That's why the SART Executive Council advises that "comparisons of clinic success rates may not be meaningful because patient medical characteristics and treatment approaches may vary from clinic to clinic." 

The Fertility Center provides an honest and accurate assessment of each couple's potential success and advises the best methods for achieving a pregnancy. We do not restrict procedures to only those patients most likely to boost our success rates. Here’s our data from last year which includes as positive all pregnancies with a clear gestational sac as well as undelivered pregnancies. Keep in mind that sometimes all retrieved embryos are cryogenically preserved (known as a “freeze all” cycle) with plans to be thawed and transferred at a later date, often because the recipient’s body is not receptive to receiving a transfer at the time of retrieval.
