SART Data Release: 2015 Preliminary and 2014 Final
May 01, 2017
Published in: ASRM Press Release and Bulletin Volume 19, Number 15
Thirty Years of Assisted Reproductive Technology Data Collection in the USA Show More than 1,000,000 Born from IVF and Related Treatments; 65,787 Babies Born from 209,336 Cycles in 2015
The Society for Assisted Reproductive Technology, is pleased to release the latest data on assisted reproductive technologies (ART) in the United States. The release consists of preliminary data from cycles done in 2015 and final data from 2014 cycles.
With the preliminary 2015 data in, we can definitively say that more than one million babies have been born from assisted reproductive technology procedures done in the United States since SART and ASRM started to collect ART data with cycle year 1985.
For 2015, 371 SART member clinics reported 209,336 treatment cycles, resulting in the birth of 65,787 babies. (See Note below.)
Positive trends in treatment and outcomes continued in 2015, with 34.5% of all cycles that progressed to embryo transfer transferring a single embryo, compared to 27.2% in 2014.
Fewer embryos transferred leads to lower incidence of multiple birth: 80.5% of babies born from 2015 cycles were singletons; 19.1% twins; and fewer than one-half of one percent were triplets (or higher order).
Other trends were noted, as well. With improvements in egg cryopreservation techniques, the use of frozen donor eggs has increased. In 2014, 2886 recipient cycle starts used frozen donor eggs; in 2015, this number rose to 3215. The number of donor embryo cycles also increased to 1428 in 2015 from 1184 in 2014.
SART President, Kevin Doody, MD, said, “While the form and specifics of our data collection have changed over the years, from the more narrative Registry Reports published in Fertility and Sterility up to the early 2000s, to our new multifactorial system, we are immensely proud to have created an organization committed to reporting comprehensive data on ART. The newest iteration of our reporting involves yearly reports that are later updated to include additional pregnancies and births resulting from embryos preserved from that year’s cycles. This results in a more accurate picture of success rates. Our National Report and individual clinic reports are presented in terms of patient age groups and can be sorted by several different filters to yield the information patients are most interested in.”
Individual clinic statistics presented are from SART member clinics that reported their data through SART. The most up-to-date National statistics are from the 2014 Clinic Specific data. However, the preliminary 2015 data are also available.
Note: We originally reported 213,004 cycles for 2015 in last week's press release. 3668 of these cycles were pulled back to 2014, as related to ovarian stimulation cycles in that year.
