I’m so confused. Egg retrieval from my first IVF was done on Tuesday. They got 17 eggs. I got a call the next day saying that only 4 of those eggs were mature and only 3 of those 4 fertilized. She said they had a few others mature overnight. I got a call today saying 5 more matured overnight, and 4 of those fertilized. I had planned on doing CCS (comprehensive chromosonal testing), because I have heard the success rate is higher. True, you can be left with fewer embryos after the chromosonally abnormal ones are weeded out, but the genetic counselor at CCRM said that there’s an 80% pregnancy success rate when two chromosonally normal embryos are transferred back in.
My issue is that the embryologist said that since I only have 7 embryos, I have to decide if I want to continue with the CCS or freeze on day 3. I’m not sure I understand. Isn’t it true that if an embryo isn’t going to survive to day 5 (which is when they would do the biopsy for CCS), it probably isn’t good anyway? She said that sometimes they will freeze at day 3 because then they can transfer back in a day 3 embryo and get it into its natural environment so that it has a better chance of surviving. But I’m thinking I would still want to do the chromosonal testing since the success rate is higher. Or should I not do it since I don’t have that many embryos to work with, and keeping those embryos out until day 5 might harm them more? Any thoughts on this? What would you do in this situation?
Note: Fresh transfer isn’t an option because my uterline lining hasn’t had any preparation.
