Think of it as a lock and key, or perhaps a post box with a specific address on it.
Like commenting out code, or dip switches on your motherboard
Now that is just one cell. A whole bunch of cells grouped together is called tissue. If you have enough hormones, all the cells switch over. Or none. Or some. It's like voting, really.
These are called 'secondary sex characteristics' and its the stuff we key off for attraction
Likewise, trans women taking androgen blockers, estrogen and sometimes progesterone get boobs, soft skin, softer hair, cheek apples and all their cake goes to their hips all of a sudden.
Hormones in, cells change, different bits of DNA express themselves.
Well, actually it does. A lot. And I can talk about that from a science point of view in a later thread, however what you need to understand is there are windows of opportunity.
That vote seals the deal for certain ducts in the body. A duct is like a tube of cells, from which more complex...
They react to hormones too, either hanging around or destroying them.
Once a duct is destroyed, it aint coming back.
So, that window of opportunity has closed.
So what happens if the hormone levels change?
Trouble, That's what.
Or your body is missing an enzyme that means it starts to produce androgens instead of adrenaline?
Humans, unfortunately, are far more complex than that.
We do not come in 100 male and 100 female flavors. Our genetics doesn't contain one code set.
Ever wonder why old ladies often get hairy chins?
Ever wonder why trans people who use HRT start looking completely different?
Ever wonder what intersex is? Or why you can't do a single blood test to find out the sex of an athlete?
It is in our nature to have variety.
Humans do NOT come in two neat biological categories with hard lines between us. We simply don't.
We are way more complex.
I hope that helps.
I say "usually" because, like any good beauroceacy, forms can get misplaced.
Ovaries and testicles are homologous. Same tissue, different set of instructiona being expressed. Got it?
It's a chain reaction
And that's assuming the chain reaction went off like domino alley. If not... well, you get a variation.
See? Humans are complex.
Good night. Science loves you even when idiots don't.
Trans women are women.
Intersex people make up over 1.6 percent of the population.
Non binary people are valid.
Humans are complex.
