Generations Fertility Care's IVF Success Rates

Society for Assisted Reproductive Technology

At Generations Fertility Care in Middleton, Wisconsin, our IVF (in vitro fertilization) success rate ranks us as one of the most successful IVF programs in the United States.

Our IVF success rates have been very high since our regrouping as Generations Fertility Care, a joint venture between UW Health and Meriter.

 

IVF Pregnancy Rates

 

In 2013, for women younger than 35 years old, 60.9% of embryo transfers at Generations resulted in live births or ongoing pregnancies. Shown below are the rates for all age groups last year compared to 2012 national data (NOTE: These data are non-SART data, since 2013 will not be reported online until 2014).

 
UW Health Generations Fertility Care: Live Births or Ongoing Pregnancies

 

In 2012, for women younger than 35 years old, 45.8% of embryo transfers at Generations resulted in live births, close to the national average (47.1%).

 

Understanding Success Rates

 

Outstanding Elective Single Embryo Transfer Rates (eSET) at Generations

 

UW Health Generations Fertility Care: Percent of All Cycles with eSET

Our goal is to transfer the optimum number of embryos to maximize your possibility of pregnancy, while minimizing the risk of a pregnancy with more than one fetus.

 

Multiple pregnancies can be uncomplicated. However, even twin pregnancies are known to have a significantly higher risk of fetal and maternal fetal complications including, but not limited to, preterm delivery and extreme preterm delivery (birth at <37 weeks and <32 weeks), low birth weight, birth defects, extending neonatal intensive care unit stays, learning disabilities, diabetes of pregnancy, cesarean sections and prolonged bed rest.

 

We hope to give you one healthy baby from each embryo transfer.

 

The best way to avoid the implantation of more than one embryo, and to increase the likelihood that you will have a safer singleton pregnancy, is to transfer only one embryo.

 

We strive to maximize pregnancy rates and the safety of each pregnancy. 

 

Definitions

  • Live births: Birth of one or more babies as a result of an embryo transfer.
  • Ongoing pregnancies: For purposes of the figure above, an ongoing pregnancy is defined as a pregnancy within the uterus with a fetal heartbeat present at the time of the first-trimester ultrasound. A small percentage of patients will be expected to miscarry after detection of the fetal heartbeat, especially in the older age groups. We are considering only those patients that have not had a miscarriage.

More Information About the Data

 

The rates above reflect patients with a variety of different fertility diagnoses and ages. These rates are a combination of both blastocyst (embryo on day 5 or 6) and, rarely, day 3 embryo transfers.

 

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.

 

Other factors that play an important role in success are a patient's age, reproductive history, diagnosis, prior therapy (type and duration) and results of that prior therapy.

 

A 25-year-old woman who had her fallopian tubes removed due to three recent ectopic pregnancies has a better chance of success than a 38-year-old woman who has completed five cycles of therapy involving superovulation that resulted in a poor ovarian response and no pregnancies.

 

Many programs have different criteria for initiation of fertility care as well as different thresholds for cancellation. When comparing success rates among clinics, make sure the figures are comparable.

 

Understanding Success Rates

 

Understanding IVF pregnancy rates can be confusing for patients. Generations feels that this information should be presented alongside information that defines what is considered a pregnancy and how many embryos are transferred at a time.

 

Pregnancy rates can appear higher because a higher number of embryos are transferred. To make sure the patient is similarly comparing the data, we feel that the average number of embryos should be included. For example, a pregnancy rate that is 30 percent where an average of two embryos are transferred is not necessarily worse than a pregnancy rate that is 50 percent where an average of four embryos are transferred.

What is SART?

 

The Center for Disease Control (CDC) and the Society for Assisted Reproductive Technology have compiled statistics from multiple centers. They require data be collected in a standardized format for presentation.
