Hi Alana,
I don't think I have come across anyone, on this site, with the same sad story as your friend. It would be very difficult for them and it is great that you are trying to give them some support.
We were lucky enough to have a baby naturally at 40 but have been trying now for over 2 yrs to have another. We are looking at doing IVF using donor eggs as our doctor says that will give us a much better chance.
Maybe your friend could think about that but it would be a very difficult decision to make when you really want a child of your own.
