Given the ‘control’ by God over the womb demonstrated in Sarah, Elizabeth, and other women I can only read the claims as supposed as per what is known about tradition.
God is the Creator, not man. Children are conceived by the grace of God. They are formed in the womb by the hand of God.
The children conceived in rape are still God's creation. It will always be a sin to abort them. They are not trash. They had no hand in their own creation and no hand should be allowed to destroy them.
