minnie - congrats on 11 fertalised, great start. to answer your question about thawing, i have had differing results from the 2 clinics i have used. first clinic i lost 4 in the thawing process, out of 10 embryos collected over 3 x stim cycles (hope that makes sense!). current clinic has been much better, think ive lost a couple but that has been bc i thawed 2-3 out at the same time and grew them to blast. so it could depend on your clinic lab, or just quality of embryos at the time. doesnt help with your decision making, i know... pity they cant do the pgd for you straight away. the stim i just did, i got 13 at epu, 11 fertalised, 7 biopsied, ended up with 2 normal blasts. so maybe a second stim wouldnt be out of the question? how many does your clinic let you batch? (mine say 6-7 biopsied, anything over that and they treat it like 2 x pgd rounds and charge extra).
