> Intersex defects prove the point that human males cannot become pregnant.
If your preferred (culture-warring yourself into thinking you know more than all the doctors whose job is to work on this) definition of "male" is simply "can't get pregnant", aside from all the thigs wrong with that, it also means you'd have to accept that if and when a womb gets transplanted into someone who was born without one, they changed gender. This is a thing being researched.
Worse for you: it is trans men (i.e. identified female at birth, transitioned to men) who have the capacity pregnant, though only in certain conditions that I'm not qualified to enumerate. If they have a hysterectomy as part of their bottom surgery, no pregnancy, so do you accept they're men afterwards?
Me, I prefer to go by simple (clothed, even) exterior phenotype, it doesn't require invasive scans or being a creep.
