Delaware IVF Center Reports One Week Old Blastocyst Embryos Are Often Viable

Reproductive Associates of Delaware (RAD) has reported that healthy and successful pregnancies have occurred from previously frozen day 7 embryos. The IVF Center’s results were detailed in an oral presentation at the October, 2012 national meeting of the American Society for Reproductive Medicine (ASRM) in San Diego, CA

“Most IVF centers do not observe or freeze blastocyst embryos as late as day 7 after the egg is fertilized, so we’re very progressive in that respect,” said RAD Lab Manager Stacy Carney. As noted in Carney’s presentation, most clinics do not consider embryos for cryopreservation beyond day 5 or 6 of development because of added workload and perceived marginal returns on pregnancy rates. “There is a subset of patients who may not have viable embryos on day 5 or 6, so by continuing observation until day 7, we often identify healthy embryos for cryopreservation,” added Carney. In other centers, patients without developed embryos by day 6 must typically complete a second fresh IVF cycle for a chance of pregnancy. By freezing healthy day 7 embryos, patients may avoid this second cycle. “Our approach creates the opportunity for potential pregnancies not typically offered at other clinics,” commented RAD Lab Director, Linda Morrison.    

Along with Carney’s presentation, two additional RAD abstracts were chosen for the conference. Embryologist Caitlin Boylan presented results demonstrating a high rate of overnight survival in previously frozen and newly biopsied embryos. These findings open the door to safe chromosome testing and highly efficient single embryo transfers for previously frozen embryos. RAD’s poster presentation, by lead investigator Katharine Shelly, focused on assessing the validity of in-house genetic screening technologies. “We are very fortunate to have our research chosen for presentation. This reflects well on RAD and helps us offer state-of-the-art lab options for our patients,” stated Shelly.

“Our lab’s observations and results point to increasingly safer and more efficient IVF outcomes,” noted Dr. Ronald Feinberg, RAD’s IVF Medical Director. The Center has a multi-year track record of utilizing single embryo transfer and pre-implantation genetic screening (PGS) to maximize healthy pregnancy results.
