It is and I’m a bit on the fence with this one as I have cousins who were conceived this way - but ultimately I believe God is the one in charge of that miracle - not a doctor playing God. God has given many parents who were barren the miracle of life once they step onto his righteous path. IVF takes God out of the equation unless of course God leads people there but why would he do that when he is all powerful and can make any woman pregnant by will - even a virgin like Mary or an old woman like Sarah.
