if money were not an option...

which would be the best and then 2nd best case scenario with regards to choosing what method:

fresh transfer vs FET
and
what type of PGD testing (i.e. acgh, natera, FISH etc)

You have asked the million dollar question because it really is an individual thing.

For me, best case is FET and whatever PGD full chromosome testing the clinic I had chosen uses.

I would choose my clinic and RE first and make sure I am happy and comfortable with them and just trust in their testing methods. If it is a good clinic, then their testing methods will reflect that.

Reasons for not doing FET are travel, some clinics prefer fresh transfers still and are not as good at FET's. No down time in between.

I did fresh tf due to travel & age. You usually only get a few normals of your desired gender at best each cycle. It took me 3 stimulation cycles to get pregnant. If I had done FET I would have taken longer to get to my goal. At 38 & travelling from Australia I didn't think it was ideal.

It's also possible to travel for your FET & the embryo not thaw. It happens & you would have spent time & money on the cycle.

I would only do full 24 chromosome testing. It greatly increases your chance of getting pregnant and not miscarrying.

Good luck.
