Apologies if this is confusing, I haven't quite got it in my head what question I am asking 
SIL has undergone countless IVF treatments, all either unsuccessful or (more recently) terminated as incompatible with life 
She is 40 and has decided to give up on the ivf front.
I am 30 and have one child, with plans to have another (if I am so lucky)
I am considering offerng DSIL my eggs. I know it sounds patronising, and there is no way I would want that, though I know of no better way to offer her.
The problem is that DH does not think I should. He thinks that SIL would not be the best mother, nor is it for me to try and play god for her. He also thinks that everytime we looked at her child, we would see our potential child, this upsets him.
My solution would be to offer her my eggs, with the understanding that any "spare" eggs of my own would be frozen for future use.
ANYWAY, the point of this long outpouring is not only a WWYD? But also I am wondering what is the procedure for egg donation please?
