"Vanessa (🙄)": "And apparently sex ISN'T, in fact, defined by presence of ovaries or testicles."
Yup, it is. You might try getting your head out of your nether regions, and those of your buddies, by doing a bit of reading and thinking with it. For example, see the definitions for the sexes in the Glossary of this Journal article on "Gamete competition, gamete limitation, and the evolution of the two sexes; Jussi Lehtonen, Geoff A. Parker; Oxford Academic; Molecular Human Reproduction, Volume 20, Issue 12, December 2014":
"Female: Biologically, the female sex is defined as the adult phenotype that produces the larger gametes in anisogamous systems.
Male: Biologically, the male sex is defined as the adult phenotype that produces the smaller gametes in anisogamous systems."
And the Oxford Dictionary of Biology -- more or less the gold standard in biology -- says pretty much the same thing:
Only a screenshot in the tweet, but this is what it says for "female":
ODB: “female: 2) Denoting an individual organism whose reproductive organs [ovaries in humans & other mammals] produce only female [large] gametes.”
Maybe, with your vast knowledge of biology ..., you might explain, to all & sundry, exactly how one might be said to produce large and small gametes without having, respectively, ovaries and testicles? 🤔🙄
Male and female, as sexes, aren't a matter of "best 3 out of 5" -- as particularly demented transwoman Riley Dennis insists is the case:
The single "necessary and sufficient condition" to qualify as male and female is to be producing (present tense) either small gametes (sperm) or large gametes (ova). No tickee, no washee; you and a great many transwomen and transmen are sexless -- suck it up buttercups.
