IVF Success Rates

At Stanford, we see couples with both high chances of conception through in vitro fertilization as well as those with more complex issues. We have no exclusion criteria for treatment, and thus our statistics include couples with low chances of success. Your chance of live birth may be significantly different than the rates for our practice overall depending on a number of factors which will be discussed at your first consultation. Our physicians work with you to individualize the predicted chances of IVF success based on your unique situation.

For couples who plan to have children later in life or for women with conditions that might delay IVF treatment or impact fertility, we also offer a range of fertility preservation services including options for cancer patients.

Our 2015 success rates are as follows:

2015 Preliminary Live Birth Rates - Patient's Own Eggs <35 35-37 38-40 41-42 >42
Cumulative Outcome per intended Egg Retrieval 54.5% 29.8% 19.6% 9.0% 5.5%
Primary Outcome per intended Retrieval 46.5% 22.3% 17.9% 9.0% 4.1%
Subsequent Outcome (Frozen Cycles) 45.6% 33.3% 36.6% 5/17 1/12
Live Birth Per Patient 61.8% 37.3% 28.0% 6.5% 5.9%

Cumulative Live Birth Rate per Ovarian Stimulation Attempt: Cumulative likelihood of achieving at least one live birth per each autologous ovarian stimulation. Includes primary and all subsequent frozen embryo transfers. It also has been called, “total reproductive potential.” The advantage includes:

  • Reflects that ovarian stimulation and egg retrieval represent the most significant patient ART expense, discomfort and health risk.

Primary Embryo Transfer Success Rate: Live birth per cycle as a result of the first transfer. A primary transfer may be a:

  • Fresh embryo transfer, or
  • First frozen embryo transfer (FET) following a “freeze all” cycle. The intent of the cycle was to achieve pregnancy within a 12 month time-frame.

Subsequent Frozen Embryo Transfer Success Rate: Live birth per frozen embryo transfer cycle which follows a primary transfer. Excludes the first frozen embryo transfer following the “freeze-all” egg/embryo cycle. May be an FET cycle which follows an unsuccessful primary transfer. Or an FET which follows a prior successful transfer which resulted in live birth.

Live Birth per Patient: Likelihood of achieving at least one live birth per each individual patient undergoing autologous IVF treatment(s). May include multiple oocyte retrieval cycles and multiple fresh and frozen cycles for each patient, including all deliveries complete by 2 years after the reporting year of the first retrieval.

Rates may vary by clinic

According to the Society for Assisted Reproductive Technology (SART), a comparison of clinic success rates may not be meaningful because patient medical characteristics, treatment approaches and entrance criteria for Assisted Reproductive Technologies (ART) may vary from clinic to clinic.
