Embryo adoption is a last-chance option to be considered once you've tried everything else.
I heard this one from the Reproductive Endocrinologist whom we saw for the first time after we'd decided to do EA. He told us that there were a lot of issues surrounding "third party reproduction" (which term puts EA in the same category as sperm/egg donation and surrogacy), and that we shouldn't be considering it at our age (mid-20s). He was confident that I could get pregnant easily with a minor surgery and some ovulation inducing/strengthening medications. "Embryo Donation," he said, "would be a good option for an older couple who has tried everything else."
I don't really see why he thought his opinion mattered. To be fair though, we didn't push it that visit- we waited until our follow-up a few months later to tell him we hadn't changed our minds. I'm not sure what he thought we'd regret, but whatever it is hasn't materialized. Any kind of adoption might be a choice made after other family-building attempts, or it might not be. For us, we were considering adoption at some point in life anyway, so it didn't take much to push us in that direction. And the fact that we were young made EA all the more attractive, because it gave one more element in favor of embryo survival! It's funny, but right now having a biological child feels much more like a fairly tale than the path we chose.
Conclusion that EA is only for aging, desperate couples who are out of other options: False (but you might have to work a little bit harder to convince your RE)!
The proof is in the pudding, as they say:
