Does a fetus receive blood from its mother?

Les teaches that the very physiological makeup of the woman's reproductive system shows the fetus in the mother's womb never receives any of the blood from the mother. He acknowledges this blows the mind of many people, but insists it is physiologically true: the blood of the mother never courses through that fetus or infant in her womb. Instead, the blood comes from the father. Therefore, Christ as the seed of the woman had to be virgin born; otherwise the blood would have come from a human father, which would have tainted His divine ability to die for the sins of the world. His blood came from the Father, as does every other creature that is reproduced. Les also recalls reading an article on cattle genetics, where veterinarians at Colorado State University proved the same thing in cattle: none of the blood of the mother cow ever courses through the fetus, and the blood system comes from the sire. He concludes this is all part of God's intrinsic plan preparing for the virgin birth—that Christ's blood was divine because it came from His Father, who was God Himself. He anticipates the question about the RH factor but the context ends there.
