Hmmm this is a really tough one.
For me the easy bit is to say that I definitely wouldn't be a surrogate for someone else. Firstly, they probably wouldn't want me but also because we've found it so hard to conceive ourselves that if we do ever get PG it will be so precious and special (not that other people's aren't IYKWIM) I can't imagine going through that and being able to hand away the baby at the end. I know I just couldn't handle it.
As for using one. Ultimately, I don't think so. I'd be so nervous that something would go wrong and that they wouldn't hand over the baby at the end.
MrsE, I think you're right about the birth certificate thing. How hard to bear would that be, even if it was your egg that the other woman would be classed as the mother?
As for egg donation, probably not either. You'd have to go through the stimulation part of IVF to produce the eggs for collection and go through the egg collection process. Could I do that again for someone else? Well, no I don't think so.

I'm not even sure I could do it myself again.
I have donated some of my eggs that didn't make it for research into IVF, specifically ICSI which is the treatment we had where they inject a single sperm into the egg. It's highly complex and they use the eggs that don't fertilise to practice the injection on with a tiny bead.
I have also donated the fluid that surrounds my eggs to research. When they collected the eggs they kinda drain that off and normally it gets chucked. They're doing some research at my hospital to see if there is anything in there that would indicate why someone has fertility problems.
Here's a question for you? Would you donate embryos? Just say for instance OH and I are incredibly lucky and every embryo they transfer is successful and we have a child. I have 2 in me now and 6 frosties in store. I know there is someone on here TTC Number 8, but that's not for us! We are allowed to keep them in store for 5 years. After which they will want to destroy them, carry out research on them or donate them to another couple. I have to say, none of which are fabulous options and is a decision that realistically we're unlikely to face, but what would you do if you did?
