I think freeper Pinkbell summarized it quite well here.
one can have IVF without destroying embryos
which would be the way I would go
my cousin and his wife tried twice.
they harvested her eggs.....
were able to fertilize several and implanted them
she had several hold to the uterine wall but later miscarried them all
they had already told the doctor that if all three implanted took, they would have all three and not abort any period
