Our Success Rates
2016 Live Birth Rates at Pacific NW Fertility
Understanding the success rates at your fertility clinic is important before moving forward with treatment. Though success rate are meticulously reported annually by most American clinics to the Center for Disease Control (CDC), and to the Society for Assisted Reproductive Technology (SART), the ever-changing field of infertility can make the data extremely difficult to understand. Understandably patients want to compare clinics’ success rates as they make a final decision about where to pursue treatment. But comparing clinics using this data is discouraged by SART because of the complexities of infertility treatments and each clinic’s differing approach to care.
For example, Pacific NW Fertility is committed to the ideal of one healthy baby at a time while many clinics are willing to transfer multiple embryos to achieve a pregnancy despite the well-documented risks of multiples. Twin births, a common outcome after transferring two or more embryos during IVF, have higher rates of birth defects and complex disorders and diseases. Because of these risks, Pacific NW Fertility strongly encourages patients to transfer one embryo at a time. That well-advised caution can show up in success rates’ data, but is easily misunderstood by patients trying to make sense of all of the numbers. And this is only one example.
PNWF’s success rates, utilizing chromosomal screening (CS) of embryos prior to transfer, are illustrated in the graph above. The average number of embryos transferred to achieve live birth in these cases was 1.05, reflecting PNWF’s ongoing commitment to the practice of single embryo transfer (SET) and maximizing safe and healthy pregnancies for our patients.
Your Pacific NW Fertility physician will be happy to walk you through these complexities, your personal success rates, and provide you an honest assessment of your statistical chances of achieving your goal of a taking home a baby based on maternal age and overall health and sperm quality and a host of other factors.
DONOR EGG PROGRAM SUCCESS RATES
PNWF’s sizeable donor egg program, includes our world-renowned frozen donor egg option that has led to over 200 live births, provides an important option for many patients. With a commitment to single embryo transfer, the average number of embryos transferred in our frozen donor program in recent years is 1.0. With the health and well being of mother and baby as our focus, success rates in our donor egg program well exceed the national average. While twin babies are the goal of many patients, PWNF’s physicians work to educate patients about these high-risk pregnancies and advocate for single embryo transfer whenever possible.
DISCLAIMER ABOUT SUCCESS RATES
A program’s success is attributed to a variety of factors including the experience and dedication of the physician and laboratory teams, individualized IVF protocols, as well as laboratory conditions and techniques. A comparison of clinic success rates may not be meaningful because patient medical characteristics and treatment approaches may vary from clinic to clinic. Reputable U.S. fertility programs follow the guidelines of the Society for Assisted Reproductive Technology (SART) to report success rates. SART has developed a national database for reporting fertility treatment outcomes. The report is generated by SART and published by the Centers for Disease Control (CDC). This system assures consistency in reporting clinic outcomes around the country. For more information, see the CDC website.
Pacific NW Fertility does report all pregnancy and live birth success rates to the Society for Assisted Reproductive Technology (SART), later published by the Centers for Disease Control (CDC). While the data is readily available for the public's review http://www.cdc.gov online, the data is not a reliable way to assess a laboratory's over all success. (NOTE: A clinical pregnancy rate at Pacific NW Fertility is defined as a positive fetal heart tone confirmed under ultrasound guidance at 7 weeks.
Pacific NW Fertility follows guidelines on number of embryos transferred that are set forth by the American Society of Reproductive Medicine (ASRM). Those guidelines are:
In patients under the age of 35 and for patients using donor oocytes, no more than 2 embryos should be transferred in the absence of extraordinary circumstances. For patients with the most favorable prognosis, consideration should be given to transferring only a single embryo.
For patients between 35 and 37 years of age having a more favorable prognosis, no more than 2 embryos should be transferred. All others in this age group should have no more than 3 embryos transferred.
For patients between 38 and 40 years of age, no more than 4 embryos should be transferred. For patients in this age group having a more favorable prognosis, consideration should be given to transfer of no more than 3 embryos.
For most patients greater than 40 years of age, no more than 5 embryos should be transferred.
The first thing I put in my baby's baby book was a pasted in sheet of paper showing that we were pregnant, from PNWF. Below it I wrote, "Mom and Dad worked HARD for you." We deserve it even more, I say. Because the baby that comes from PNW Fertility and their crew of helpers is one loved baby. That is a pretty amazing legacy to be able to tell that kid someday.
