We are trying to decide between doing a fresh transfer or freezing and doing an FET later. Our cycle is set for May and there are a few things (one test result thats lagging, unexpected difficulty being away from work for 2 weeks straight) that are making us lean towards an FET.
I started looking at FET info and I keep seeing comments about “only 1 made it to freeze” when there were 5 good looking embryos… So what gives? I understand that vitrification is an improvement over the older slow-freeze method, with 95% thaw rates. But why aren’t more making it TO the freezing process?
Any advise or perspective on this would be appreciated! I’m stressing out about this. I don’t want to go through a cycle and end up with 0 embryos. The only thing I’ve come up with is that they need to be at the correct number of cells for how many days old they are and under a percentage of granularity.
