There are a variety of methods used by medical professionals to grade frozen human embryos, to project the likelihood of pregnancy success. This often includes Preimplantation Genetic Diagnostic (PGD) and Preimplantation Genetic Screening (PGS) testing.
However, research has shown that these tests are not always accurate. Even lower quality embryos, when thawed and transferred, may result in healthy babies just as higher quality embryos do.
According to World Magazine, “Over the last few years, a handful of physicians in the United States and Europe have reported that embryos deemed abnormal by early tests could still grow into normal pregnancies—and they have the healthy babies to prove it. That means physicians have thrown away perhaps tens of thousands of embryos deemed abnormal that could have been healthy.”
One Snowflakes family knows this first hand. This family adopted six embryos and chose to thaw all of them. Four embryos survived the thaw and two embryos were transferred. The remaining two embryos were re-frozen, but were deemed by the medical staff as “incompatible with life.” Unfortunately, the family’s first frozen embryo transfer did not result in a pregnancy. Against the advice of the doctor, the family chose to thaw and transfer the remaining embryos, believing all embryos deserve a chance at life, not just the “good quality” embryos. The family ended up pregnant with twins from those embryos!
There are many embryos in frozen storage at this time who are not being used for family building purposes because they are deemed “low quality” or “poor quality.” Though these embryos could result in perfectly healthy children!
