More than 71 Thousand Babies Born from Assisted Reproductive Technology Cycles Done in 2016

This week, SART, the Society for Assisted Reproductive Technology, is releasing the latest national and clinic-specific data on assisted reproductive technologies (ARTs).

Preliminary data for 2016 show that 71,296 babies were born as a result of 242,618 cycles performed during that year, at 377 SART member clinics, continuing the steady increase of ART utilization in the United States.

Positive trends in ART practice have resulted in improved outcomes for mothers and babies. The use of elective single embryo (eSET) transfer increased to 42.2% across all age groups in 2016 from 34.5% in 2015.  In 2016, each patient age group showed both increased eSET use and a decrease in average numbers of embryos transferred per cycle, from the previous year. 

Fewer embryos per transfer led to a reduction in ART multiple births from 2015 to 2016.  Of the babies born from 2016 cycles, 84% were singletons, 15.6% were twins, and 0.4% were triplets. These rates improve on 2015’s, in which 80.5% babies were singletons, 19.1% twins, and 0.4% triplets.

While SART data show that ART is very effective, they also show that a female patient’s age is very important to predicting the ultimate success of  cycle in which she is using her own eggs.  Final cumulative outcomes data for 2015 showed that women under 35 years of age had a 53.9% likelihood per cycle of having a live birth using autologous eggs, and this dropped to 3.9% for women over 42. Recipient age was not relevant in donor egg cycles; the average chance of a live birth in a given fresh donor egg cycle was over 50% and over 38% in a frozen donor egg cycle.

SART President David Seifer, MD said, “The yearly publication of the SART National and Clinic reports reflects our members commitment to providing the public with meaningful outcomes data.  The improvement in outcomes reflects our members' continued striving to provide the best care to their patients.”

The Society for Assisted Reproductive Technology, an affiliate of the American Society for Reproductive Medicine, is the primary organization of professionals dedicated to the practice of assisted reproductive technologies (ART) in the United States.  SART’s mission is to set and help maintain the standards for ART in an effort to better serve its members and their patients.
