Check out the SART statistics for your clinic. My first IVF at 27 with MFI ended up with a sucessful singleton pregnancy from our first double transfer and a singleton pregnancy miscarriage from transferring our last two. Our second IVF at 31 yielded 3 blasts and am currently 27 weeks with our first transfer of a single embryo. We didn't test embryos with either cycle.

I had 3 PGS normal embryos at 36. Only one stuck.
My only issue is PCOS.

My experience was 1 in 3 but of course this is highly variable. I was much older (34) for starters.

If not tested, then it could be a range. If tested the general rate is 60-70%

We have 5 5-day blastocysts frozen, none are tested, frozen at 28 or 29 years old, (can't remember), dx unexplained infertility. How many can I expect to actually make it to a fetus. I thought there was a chart or percentage that gave a general idea? I know there are a number of variables to consider, but ballpark range?
