IVF Pregnancy Success Rates

Since 1992, the Center for Disease Control and Prevention (CDC) has mandated that all fertility clinics performing assisted reproductive technologies (ART) in the U.S. provided data annually. In addition to helping the medical field better understand the successes of fertility treatment, this data helps patients identify fertility clinics with the best pregnancy rates.

The most recent report is based on 2011 data from 443 fertility clinics nationwide.

In addition, the Society of Assisted Reproductive Technology (SART) works closely with the CDC in compliance with the Fertility Clinic Success Rate and Certification Act of 1992 (Wyden Act). To become a member of SART, fertility practices need to comply with regulations; for example, the embryology lab must be accredited every two years and the medical director must be a board-certified reproductive endocrinologist.  SART publishes pregnancy rate data for fertility clinics nationwide.

Single women interested in starting a family on their own are in a unique position; while they will need the help of a third party donor and a reproduction team to achieve pregnancy, they are not necessarily suffering from infertility. Because of this, RMACT recommends that patients interested in comparing fertility practices and national averages review IVF pregnancy success rates for the following:

  • live births for patients 35 years old or younger
  • frequency of multiples; low rates are best
  • number of embryos transferred at a time; transferring one to two embryos lowers the risk of multiples

 

Pregnancy Success Rates

For the period of January 1, 2010 to December 31, 2010

These statistics represent outcomes for patients who have undergone embryo transfer. The percentages are calculated by dividing the number of women who achieved a clinical pregnancy (numerator) by the total number who underwent a transfer (denominator) from January 1, 2010 to December 31, 2010. Please keep in mind that a variety of individual factors may increase or decrease your likelihood of having a baby.

A comparison of clinic success rates may not be meaningful because patient
medical characteristics, treatment approaches and entrance criteria
for ART may vary from clinic to clinic.
