Look up testicular feminization. A genetic defect that lacks an enzyme (5 alpha reductase) that doesn’t allow the fetus to develop male parts but is XY. Typically have android pelvis and is estimated to be very prevalent in high end fashion models (-10%) and in a well known movie actress
that is 5-ARD
Always read Jamie Lee Curtis may have some such malady 🤷♂️
So that's why I never have "movement" when looking at so-called super models. Tom Brady's wife comes to mind.
