I didn't use donor sperm, but if you don't mind an outside perspective... IVF is so unpredictable, if you really have your heart set on full bio sibs, the "investment" would be worth it. I would've felt more comfortable with the "back up insurance" just in case I needed more embryos if it were me.
Here's my reasoning: IVF 1 was a success and we had 9 pretty good quality frozen embryos. I was 33. By 35. I was ready for sibling. RE and I were optimistic about FET 1 because of IVF success and quality of embryos. Out of the 9, only 3 survived the thaw. We transferred all three hoping that one would stick, but none did. RE and I were both shocked and not expecting that. After failed IVF 2 we discovered I had uterine polyps that might have been the reason for the failures. Had the polyps removed and so far BFP on HPTs with FET 2. We transferred 3, but not sure how many stuck until u/s.
Don't want to be a downer, but just wanted to throw out some real life scenarios to think about. GL.
Not a downer at all, this is exactly the kind of stuff I want to hear. Everyone keeps telling me what a "sure thing" this is because I have 5 good embryos, but all it would take is a couple of bad thaws, a couple BFNs and a m/c for us to be back to square one. I know I am lucky to have those embryos, but I have read too much on this board to be confident about my success at this point!
Thanks to everyone who has responded...I agree that it seems like kind of a no brainer when you put the $350 in the grand scheme of IF costs. I think my main problem is that it's going to tricky to convince my wife we should go for it. But I think it is becoming clear to me what *I* want to do...
