The structures that unambiguously always define male or female are the structures that produce functional gametes. I interpreted “how folks that were never going to produce either fit into that definition” as asking “If we don’t look at the gonads, what would we use to determine sex”. Those ducts are a very good indicator, but are secondary structures around the gonads. If you wanted to determine sex without looking at gonads, those are one of the primary structures for doing so.
Ovotestes are interesting, but probably not what you’re thinking. They’re not just normal testes and ovaries as one might be lead to believe from the name. They’re exceedingly rare, so have to be examined individually and general statements can’t really be made. You’ll probably find a (semi-)functional gonad from which their sex would be determined, with a sampling of non-functioning tissue from the other sex. You’ll also likely find that the surrounding structures and rest of their body is unambiguously male or female, though again you’d have to look at a specific case.
To bring it around to near the start of this thread, even then, the body isn’t organized around producing no gametes. It’s organized around producing gametes and failing to do so.
the body isn’t organized around producing no gametes.
After looking some case reports it looks like a lot of folks with ovesterticular disorder have both sets of genetalia and neither can produce gametes. These folks tend to choose a gender (usually the one they grew up as pre-puberty) and get hormone therapy and such to affirm it.
Since “sex is a binary” is a universal claim, it only takes one existential example to disprove it. I was pretty convinced by the case reports I read that the sex binary can’t include every person.
I’d be convinced if ya presented a definition that could be used on everyone.
But at this point I think we are splitting hairs. It seems obvious to me that there is a range of ways sex can exist in humans. At this point a definition for the binary would have to be pretty complex and people close to the boundary would likely be very similar despite getting opposite labels. It’d be like saying there is a binary of black and white and the line is at R127,G127,B127. I mean sure, but we both know we are just drawing a line in a spectrum.
