The term “pre-embryo” and the associated false period of human development were invented in the late 1960s to establish a reduced status for an already existing human embryo. They were devised and advanced without a mandate from human embryologists. Depending on usage, the term was intended to indicate either that no human “person” was present in the so-called pre-embryo or even that no human being was present, either before implantation (which occurs five to seven days post-fertilization) or up to seven days after it.
In support of this claim, we already have a term for that thing after the egg is fertilized by the sperm, forming a new organism: Zygote. (Incorrectly but descriptively known as a “fertilized egg.”)
Then the cell splits and it’s an embryo.
Note, in standard IVF you wait for the cell to split, which makes it an embryo. There is a form where you put the IVF zygote into the Fallopian tube– and also one where you directly put the egg and sperm in. More here.
I support embryo adoption, but not the “assisted fertility” methods– the former is rescuing people, the latter is trying to make people to order. I know that most of the folks doing “assisted fertility” don’t think of it that way, thank goodness, but that doesn’t change matters. The whole way of thinking about kids is deformed.
….for anyone about to go “what the hell do you know, you have five kids and really strong fertility,” I must point out I’ve got really screwed up fertility and for two years we thought I couldn’t even cycle, much less carry a child. When the Princess was born I hadn’t had a cycle for years; since then I’ve had two, no matter the NFP care. Go figure, I’m strange there, too. Since 8 years from then we have 5 kids, you can figure out that my fertility is only a worry in the opposite way, yeah, that’s fixed– but it doesn’t change that yes, I DO know that gnawing desire to have something that is not mine to claim. Kids are God’s, and their own; not mine.
We don’t have a right to kids. We have a responsibility.
