WWYD? Day 3 biopsy w/fresh transfer or Day 5 w/frozen
Hey all, longtime IG member here just finding my way over to this site. Some of you may remember me as ahimsa_malozzi. I've been ttc a DD for waaaaayyyyy too long! Joined IG back in 2006 when my DS1 was just one and I was trying to sway the odds for my second child to be a girl. Swaying failed, and after DS2 was born I tried MS/IUI twice at GIVF in 2009 but never got pg, so then I did a really thorough super good sway but nope - DS3 born last November! So now I'm planning on doing PGD/IVF late this year.
Had my consultation last week and I'm happy with the clinic and doctor I chose - best in the area for PGD without a doubt. Part of why I was so excited about them is that they're the only ones around here doing day 5 blastocyst biopsies with aCGH and day 6 fresh transfers. But then I found out at the consultation that the aCGH they do with that procedure is only 96% for gender. After all this time, I'm not about to settle for anything less than 99.9%!
I talked to them, and my options are to either do a day 3 biopsy with FISH (guess I'd do five probe) for a fresh transfer, or I could do GSN with parental assist with a day 5 biopsy, but it would have to be a frozen transfer. They claim a 90% thaw survival rate. I guess I could also do GSN with a day 3 biopsy and fresh transfer, but I didn't really talk to them about that. The embryologists I spoke to at the clinic both recommend the day 5 blast biopsy with FET because they say blast biopsy is so much better that it outweighs the drawbacks of FET.
What do you guys think I should do?
