It is ‘unethical’ to allow a woman to carry a multiple children to term, but it isn’t unethical to kill all but one of the children in the womb? Somehow I think God would disagree with these fellows.
Well, there’s an ethical hit either way, since basically the medical procedure involves creating an environment where there are many more children in the womb than normal (statistically). Hence a high likelihood that the fetuses will not make it to term, or if they do, they’ll be so compromised that they die in infancy.
