Latest Data from SART Show Increasing Use of Cryopreservation for Fertility Preservation

More than 72 Thousand Babies Born from Assisted Reproductive Technology Cycles Done in 2017; Data Show Increasing Use of Fertility Preservation; Multiple Birth Rate Continues to Decrease

The Society for Assisted Reproductive Technology, the United States’ primary organization of professionals dedicated to the practice of assisted reproductive technologies (ART) is releasing its latest national and clinic-specific ART data, today.

The preliminary national data set for 2017 shows 72,321 babies born resulting from 262,834 cycles performed during that year, an increase from the previous year’s number of 71,362 babies born form 242,664 cycles. 370 SART member clinics contributed to the report.

The most significant trend we observed is an increase in the number of egg freezing cycles, both for donor egg banking and for fertility preservation. The year 2017 saw 1447 donor oocyte banking cycles, up from 905 in 2016.  Fertility preservation cycles for patients freezing and banking their own eggs increased to 10,936 in 2017 from 8825 in 2016. 

Increasing numbers of patients across all age groups continue to choose elective single embryo transfer (eSET) with its use increasing to 43.9% of transfer cycles in 2017 from 42.2% in 2016. Accordingly, among ART-conceived pregnancies, singleton births increased to 87.4% (2017) from 84% (2016); twin births decreased to 12.4% (2017) from 15.6% (2016); and triplet births decreased to 0.003% (2017) from 0.4% (2016).

SART President Amy Sparks, PhD, said, “Year-by-year SART’s National Summary Report gives patients, professionals and the public the big picture view of the improvements and advances that have occurred in ART over the decades. We are proud of having created this resource, and we are equally proud of our clinics which contribute their individual reports, making the National Summary possible and providing their own patients and prospective patients a detailed look at their clinics outcomes.”

SART, The Society for Assisted Reproductive Technology, is an affiliate of the American Society for Reproductive Medicine (ASRM). SART's member practices perform more than 95% of the assisted reproductive technology (ART) cycles in the United States.
