OP is asking about egg donation....that's different than what we we're talking about. I'm not familiar with costs of getting a donor and the storage questions, though just like most things infertility related, I'd expect the cost is significant.
Not sure where i gave off the trolldar, but gee wiz. 20k+ is insane. Why charge that much to folks that want a child? That's not right. Anyway, thanks for the info.
First research should be regarding pregnancy risks over 40... Edit: sorry, misread your post; I realize she will carry it, not donate it.
You night be better off with a puppy. Keep in mind, that night attract pretentious American women, which might not be your cup of Earl Grey.
I was going to suggest adopting as well. Unless u are determined that the child have your dna. it sounds like adopting (although expensive) would be less expensive in your case.
Great. Start a family first, see how well you and your wife can do together. THEN have a child. Don't just "want a kid." WTF is this, a super market? "bust"? REALLY? "Why charge that much to folks that want a child?" If you have to ask "how much?", you probably shouldn't get it.
