My point remains unrebutted, that to speak of dysfunction presupposes a proper function.

Indeed, your point remains unmade, as far as I can tell. Spell it out for me. Is it some Zen thing?

You said

IVF is an end run around the disfunctioning of the body

That is, you used the term "disfunctioning of the body." For "disfunctioning" to have meaning, there must be a (presumably proper) "functioning."

Specifically, you have said in essence that IVF is a way around the bodily "disfunction" manifest as infertility.

Is it any surprise that there will be significant variation among individuals with respect to complex traits such as fertility? How, then, is infertility "disfunctional"?
