Sounds like a good plan to me. The daughter, should she decideto use them, will have eggs of her own genetic background. And there have been sister to sister egg transfers for this sort of thing. And yet some jackasses wanting to make a name for themselves are claiming this is unethical. That this will confuse the baby as to whether it's mother is it's mother or it's sister. WTF?!?!? At least the child will actually know it's lineage, and not wonder who it's "real" parents are.
I think the doctors raising a stink over this need to be slapped up-a-side their heads until they pull their heads from their asses and breath something other than their own rectal fumes.
