High Pregnancy Rates, Low Risks Reported by Pacific Fertility Center at ASRM Meeting

Committing to a consistent, clinical program in elective single embryo transfer (eSET), physicians and embryologists at Pacific Fertility Center (PFC) have achieved high pregnancy rates without the risks commonly linked to multiple births. PFC reported the results of its retrospective study on Tuesday, October 21, at the 2014 Annual Meeting of the American Society of Reproductive Medicine (ASRM) in Honolulu, HI.

The report was entitled, “Toward a Program of Single Embryo Transfer: Reducing Multiple Gestation Risk Using CCS.”

“This ASRM meeting marks a paradigm shift away from multiple gestation and toward safer singleton pregnancies,” said lead author, Philip E. Chenette, MD, who described PFC’s innovative program. It involved a consistent message, educational materials, a lecture series, and clinical and laboratory protocols encouraging eSET after comprehensive chromosome screening (CCS). The number of embryos transferred was at the discretion of patient and physician.

A way to identify embryos with normal chromosomes before becoming pregnant, CCS improved implantation and pregnancy rates in women over age 35. After CCS, fewer embryos were transferred, reducing multiple gestation risk in all age groups.

“After screening embryos with CCS and transferring a single embryo, we are achieving 50-75 percent pregnancy rates with low pregnancy risk across all age groups,” said Dr. Chenette.

From 2012 to 2013, PFC physicians performed a total of 1,034 frozen embryo transfers (FETs). During this period, CCS FETs increased by 260 percent, reflecting a significant increase in patient acceptance.
