When we looked at the number of eggs retrieved compared to the number that were mature compared to the number that fertilized compared to the number that made it to transfer/freeze there were some questions. It wasn't particularly "normal."
13 eggs were retrieved
8 eggs were mature (62%)
4 eggs fertilized (50%)
4 eggs became embryos and made it to day 5 and 6 (100%)
This isn't exactly typical, at least at my clinic. Our doctor explained that it is possible the reason I may not have been getting pregnant all along may have had something to do with my eggs. Obviously we knew with my PCOS maturing follicles would/could be an issue. It does make me wonder if we ever had truly mature and viable eggs releasing during our IUI cycles, but that is over and done with-- no regrets. The good news is, once they identified the good eggs they did make great little embryos!!!
This question of my egg quality was another deciding factor in choosing another fresh cycle. We know that right now my eggs are capable of making good embryos. If we had chosen to do a FET and gotten pregnant, there would be a little urgency for baby 2/3. With the path we've chosen, we are able to keep our two great little frozen embryos for (hopefully) a few years from now when we're ready for baby 2/3- knowing that if indeed my egg quality is going downhill, we still have hope in those two frozen embryos- plus any embryos that make it to freeze from this cycle. I can't even begin to tell you how much this puts my heart at ease.
