At the present time there are over 400,000 human embryos on ice in America. Many more flushed down the toilet when those embryos are implanted 3 or 4 at a time in the woman who pass the unused/unimplantable embryos when they menstruate.

About 80% of all naturally conceived zygotes also fail to implant.

Yeah, and some people accidentally get killed in traffic, while others are deliberately pushed in front of a bus.

"naturally conceived" that's the key and part of God's natural law and marriage covenant.

I'm not too sure that 80% of naturally conceived embryos (zygote is a term used in biology for animals) fail to implant. I know a woman passes and unfertilized egg every month. Be that as it may, according to some religions IVF is evil and causes human life to be used and discarded as mere commodities and not a "gift" from God. It is contrary to God's natural law and the institution of His marriage covenant.
