What the fuck are you talking about, and why is this garbage upvoted? Prolactin can affect milk yield. But “they are not pregnant” is absolute, categorical horseshit. You’ve either bought a lie or are lying. Look at that paper and see the disgusting, brutal efficiency with which the dairy industry researches how best to precisely rape, forcibly impregnate, and steal the offspring of cows so they can eke out fractions of a cent on each gallon of milk sold.

“Tofu will give you boobs.” “Prolactin supplements without pregnancy can drive commercial milk production.” The universe of bizarre omnivore misconceptions is apparently just a transfem paradise.
