And who coined the phrase?

[Mrs. Don-o]

I don't know. Could have been Dr. Janet Smith. I'm guessing this, only, because she's done a lot of writing on artificial reproduction technologies --- insemination, IVF, the frozen embryo cases, etc. -- and the implications for splitting procreation off from sexual intercourse.

Thus she has been exploring the "new fact" that while copulation-procreation used to go together, there could now be reproductive infidelityconsidered separately from copulative infidelity.

E.g. a husband inseminating a lot of women, while not having intercourse with any of them. Or a wife going to a 'clinic" and getting pregnant outside of marital unity.

Dr. Janet smith is well-worth reading, if you want to look into it. You're a person with education as well as insight, and would appreciate her depth, I think.
