SART Releases IVF Success Rate Data for 2010

By Leigh Ann Woodruff, February 7, 2012

The Society for Assisted Reproductive Technology has released the 2010 IVF Success Rate National Summary, the latest clinical outcomes data on assisted reproductive technologies for the year 2010.

The national SART data shows that for 2010:

  • 370 clinics reported data to SART
  • Data was reported on 146,693 in vitro fertilization (IVF) treatment cycles.
  • There were 58,727 babies born from IVF treatment cycles.
  • For fresh embryos from non-donor eggs, the percentage of IVF cycles resulting in live births for women 42 (4.1 percent )
  • For fresh embryos from non-donor eggs, the average number of embryos transferred for women 42 (3.1 )

The 2010 data reflects many positive trends, including transferring fewer embryos per cycle and increased use of single embryo transfer. “We are continuing our focus on ART best practices, performance and safety," says Glenn Schattman M.D., President of SART. "There's clearly a decrease in the number of embryos transferred, which is a steady progression every year based on SART embryo transfer guidelines.

"The number of single embryo transfers in patient groups that are appropriate for elective single embryo transfer has certainly increased," Dr. Schattman continues. "The candidates for single embryo transfer are younger patients in their first or second cycle of IVF with good quality embryos. So in that group, the percentage overall of cycles that are undergoing single embryo transfer increased significantly."

Transferring fewer embryos per cycle lead to reductions in the percentage of twins and high-order multiple births in the lower-age categories. "There is a decreased number of multiple births that have occurred, especially the high order multiple births, which are the ones you want to really try and limit," Dr. Schattman says.

There are two data sources available for IVF success rates: SART and the Centers for Disease Control and Prevention (CDC). SART reports the most recent IVF success rates of their member fertility clinics. Fertility clinics that are members of SART are required to submit their data; however, not every fertility clinic in the United States is a member of SART.

SART also provides the data for its member clinics to the CDC. The CDC's annual IVF success rates report — Assisted Reproductive Technology (ART) Report — is published after extensive verification and analysis. The CDC data is more comprehensive and includes fertility clinics that did not report to SART; however, the reports take longer to compile and publish. The most recent CDC report available is from the year 2009.

Dr. Schattman advises fertility patients not to use the SART or CDC data to compare individual fertility clinics. "It has to be quite clear that these results cannot be used to compare clinics because of the difference in patient characteristics between programs," he explains. "People look at one line and say, "OK, wow , this is the best one," but in fact, different patient populations and different techniques at each clinic make it impossible to compare statistics between programs.
