In veterinary medicine no one asks whether the embryo of a dog is animated with a feline, ovine or bovine life.
The product of human procreation is a human being. The human character of the embryo resulting from the union of man and woman has not been questioned except by those who wanted to fabricate premises to justify abortion or experimentation on embryos.
Moreover it is significant and indeed revealing that certain promoters of in vitro fertilization and transfer of the embryo say they are morally worried about the fate of those embryos remaining in vitro but not the ones transplanted in vivo.
