[QUOTE=Ghost]You are correct that a take home baby is not the definition of survival.
However, the assessment of survival is a judgment call, and two clinics, or two embryologists might differ.
A recent publication on vitrified and warmed embryos found 100% survival in the assessment right after thaw. Then they looked them a little later and 36% of them were arrested. So it depends on how long you wait after thaw.[/QUOTE]
Quite obviously no clinic worth their salt would consider an arrested embryo to have “survived” the thaw and then put said arrested embryo back inside of a patient!! Certainly not mine. Do you know of any? Most embryos thaw out…it’s what the look like and how they perform after the thaw that counts. The point is that you can’t say that because an embryo did not implant or did implant but resulted in a chemical, that somehow the embryologist made a poor assessment as to whether or not that embie “survived.” We see top graded embies put back day in and day out that do not implant or result in chemicals. Does that mean that the embryologists that make these assessments are wrong too? You also leave out the simple fact that grading alone and/or what an embie looks like does not tell us whether an embie is normal or abnormal. A frostie might not make it simply because it is abnormal. Nothing at all to do with whether an embryologist made the proper determination as to "survival
The bottom line here is that after vitrificatiopn, the OP lost 50 percent of her embies. THAT is simply unacceptable and far below the stats of most clinics that vitrify. Now…we can try to surmise that somehow the OP’s clinic is doing things better than all the rest with survival rates in the 90th percentile…but somehow…I doubt that. Moreover, there is no basis for that belief.
