The truth: Every embryo is a human being with potential.

The truth: Every embryo is a human being with potential.
Define human being. A 5-day-old blastocyst is indeed HUMAN (not dog, not mouse). But the 50% or more human embryos that are aneuploid enough to not be able to go on developing past a week or three have no full potential. If your wife had one in her uterus, she might never have known she was pregnant briefly.
So I see, say, 10 frozen embryos in a tank of liquid nitrogen, and I say that they are ALL potential human beings. Maybe when they are placed into someone's uterus, 2 at a time, maybe 5 will become people. The other 5 will probably not even register a positive pregnancy test, though perhaps one of those will, and the joyful mother will be brokenhearted in the 7th week when she loses the baby.
