What the fuck are you talking about, and why is this garbage upvoted? Prolactin can affect milk yield. But “they are not pregnant” is absolutely 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 and forcibly impregnate cows for dairy production so they can eke out fractions of a cent on each gallon sold.

“Soy will give you boobs.” “Prolactin without pregnancy can drive commercial milk production.” I’ll bet transfems wish they could live in this universe of bizarre misconceptions about an omnivorous lifestyle.
