[quote=Anonymous][quote=jindc]My first cycle, 5 mature, 4 fertilized with ICSI, by day 5 there were 3 blasts - two of which were higher quality - and one morula. We transferred the two high quality blasts and the other two weren't freezable. Not sure of outcome, antagonist protocol with lupron trigger.

I felt better about the lack of freezable embryos by reading on a clinic's web site (not mine, judt in a general search) that only 20% of all embryos are truly freezable quality (can survive freeze and thaw).  Good luck!![/quote]

That's not true about embryo survival--if the clinic uses vitrification, 80% +, and at some clinics, 90% + survive the thaw.  I don't believe that they have to be of a certain "quality" to survive.  I had two frozen at day 2, both survived the thaw and divided afterward--and I'm AMA, and didn't get pregnant, so they weren't super embryos.

I think clinics like SG put "stringent" quality requirements on freezing embryos because they'd rather have repeat business.  Despite being so "stringent", SG has a very low FET success rate.  Other clinics have a much higher rate and I'll bet it's because they're 1) better labs with better freezing and thaw and 2) they freeze more embryos, giving more of them a chance, as how they look does not seem to be a good reflection on their chromosomal normality/abnormality, which is the only important thing as far as whether it's a viable embryo.[/quote]
