Would IVF result in automatic excommunication? I know that is the ecclesiastical penalty for abortion, AND I realize that embryos are “often” killed from the IVF procedure, but wouldn’t it depend on whether embryos were killed and she knew it?
I don’t know of any IVF procedure that does not involve the destruction of embryos. If the procedure can be accomplished without the destruction of embryos it is still not morally licit. Since it is an offense against marriage I think the canonical (is that the right term) penalty would be same as for other such offenses like the use of artificial contraceptives. I do not know what that would be.
