In Vitro Fertilization (IVF) — moral issues around discarding or permanently freezing fertilized embryos

Mike addresses IVF: once an egg is fertilized it is no longer just a fertilized egg — it is a zygote, a living whole human being. He has no objection to freezing or implanting embryos per se, but the moral problem arises when frozen embryos are permanently stored ('their lives frozen forever') or discarded. He distinguishes between IVF procedures that do not harm the embryo and those that destroy or abandon it indefinitely.
