A ‘trans-man’ can take all the testosterone ‘he’ wants, but it has nothing to do with the this or thousands of other enzyme and neuro-chemical pathways designed to maintain life, not reproduction or sex expression.
I've been saying for a while, no matter how loud you scream "CALL ME MA'AM!!", if all that's left of you after an accident is a spoonful of material, that DNA will scream back "NO YOU'RE NOT!", you're a MAN!
Nguyen performed a survey of gender-related differences in lower limb alignment, and reported that the quadriceps angle (Q-angle),
tibiofemoral angle, and genu recurvatum deformity are more pronounced in females8).
It's not only on television and in movies that coroners can tell the sex of a victim (even if only the skeleton is left) by their bone structure.
For that matter, ancient human (and even more-ancient proto-human) fossils tell the same tale: male or female. Humans have gigantic brains for their body size and getting that skull through a birth canal requires a different pelvic shape with a larger opening than males have. Males also have larger and thicker skulls (females have smaller neuron size that provides brainpower parity), wider shoulders, and a bunch of other differences that don't change just because someone surgically removes their testicles (or breasts) and takes hormones.
Ah, this must be the reason Michelle Obama can do 40 pushups in his 40s
Yep!

XX and XY literally program the body not only in development but it’s adaptive mechanisms.
For example, women lack an enzyme that metabolizes alcohol.

I didn’t know this. Guess that’s why women are sloppy drunks. Not throwing shade, just personal experience in a former life!

I think we found our biologist!
Thought this was funny 😆 Q Angle

Women do not have brainpower parity.
