Thats only the term used largely for the sake of funsies in manhwa and eng community. Lots of novels act dwelve and put thoughts about this!
Take this, their lives are controlled by pheromones so its not really that weird when large amount of pheromones made their uterus function. Glands and genitals are where the pheromones are stored in large quantity of course constant penetration and biting of the gland will lead to change in the body. Both women and men in abo are originally people with dual reproductive organs that changes into omega/alpha due to pheromones so different kind of pheromones will consequently lead to different differentiations even if its late.

you're wrong, the term actually came from jap authors and they coined it.
wither you try to explain it by biology, both sex has the ability to grow a uterus in specific circumstances, it doesn't take away the misogyny of the term.
comon now it's not a coincidence that "bitching" is when a presumably "dominant" man losses his dominance and fulfil a position that's viewed traditionally feminine, which bottoming / being penetrated.
I don't know what with yall fujo bitches and internalized misogyny

Hey can you guys argue on your own comment. You're over here pointing fingers as if you aren't also at the fujo convention. Bitching, force fem and breeding are the main themes/kinks of this smut story, so (and i mean this in the most genuine, supportive way) if you don't like it, I suggest dropping it if you haven't already.
Other than the knot, what exactly are these "alpha organs"???? and why are they in the same place as a womb. "Your alpha colon is damaged" that's just a regular colon!!!!
