Understanding IVF Success Rate Statistics

The Centers for Disease Control and Prevention (CDC) and the Society for Assisted Reproductive Technologies (SART) clearly state that "a comparison of clinic success rates may not be meaningful because patient medical characteristics and treatment vary from clinic to clinic."

However, there is important information a patient should obtain by studying some of the details in the published statistics. In addition, it is important to evaluate and compare program statistics and to research the physician you choose for infertility treatment.

In general, the ability to achieve a pregnancy following IVF treatment depends on following:

  • the woman's age,
  • ovarian reserve, as assessed by a day 3 to 5 follicle stimulating hormone (FSH) level, anti-mullerian level (AMH) and antral follicle count (AFC)
  • the cause of the infertility

The reported success rates reference IVF statistics and do not represent pregnancies that result from other, less technical procedures such as various surgeries, insemination or ovulation induction.
