IVF Success Rates in 2013

According to the newly released report by the Society for Assisted Reproductive Technology (SART), over 63,000 Babies were born from in vitro fertilization (IVF) cycles performed in 2013.

Highlights from the report, which annually compiles data from its member clinics, include:

  • 380 fertility clinics performed 174,962 IVF cycles
  • There was a 6 percent increase in IVF cycles over the previous year
  • 63,286 babies were born
  • There was a 2.5 percent increase in the number of babies born since 2012
  • More than 1.5 percent of children born in the U.S. are a result of assisted reproductive technology

The percentage of live births for IVF cycles using fresh embryos from non-donor eggs in 2013:

  • Women under 35: 40 percent
  • Women 35-37: 31.4 percent
  • Women 38-40: 21.2 percent
  • Women 41-42: 11.2 percent
  • Women 42 and older: 4.5 percent

Several positive trends were evident in the report:

  • The use of elective single embryo transfer (eSET) is increasing in all age groups.
  • Fewer embryos are being transferred in all age groups
  • Embryo implantation rates have increased in all age groups
  • There is an overall decline in multiple births

With the 2013 report, SART has begun providing data on cycles using frozen donor eggs (in addition to fresh donor eggs) and donated embyros:

  • 227 frozen donor egg cycles
  • 8,921 fresh donor egg cycles
  • 1,201 donor embryo cycles

“We are extremely encouraged to see the number of embryos transferred per cycle continue to go down and that more and more patients are choosing single embryo transfer. The goal of reducing the incidence of multiple pregnancies is extremely important and patients can see from the data that fewer embryos transferred do not mean a lower chance of pregnancy,” said James Toner, MD, PhD, President of SART. “We are also excited to provide patients with national data on banked donor eggs and donated embryos for the first time. The availability of these treatment options will only increase in the future as cryotechnology evolves and as awareness grows among potential embryo donors and recipients. It is important for patients to have the data on these options so they can consider them as possibilities in their own treatment plans.”

The annual SART report provides individual fertility clinic data as well as a national summary. Patients are encouraged not to use the data to choose a fertility clinic, but rather to help them understand their chances of successful treatment based on their age and individual characteristics.
