IVF is not permitted to Catholics. It messes with life in almost the same way that abortion does. Yes, abortion. What happens to all the unused zygotes when they fertilize a batch? And women weren't meant to have "litters" of 4 or 5 children after they're impregnated with so many fertilized eggs and given fertility drugs.
Ultimately, they want her to choose to "selectively abort" some of them, before and/or after they are implanted.
The whole process is not pro-life, any more than abortion is.
