Question: what’s your source on the phytoestrogens? Bc the only times I’ve ever heard that claim, they all source back to this one study on sheep in like the 40s, which… well it’s not very well supported

(Although maybe you don’t care about that, which would be fair. These are fictional cats after all not clinical studies)

You're probably coming from Hbomberguy when he was specifically addressing lunkhead chuds, who pass around the claim that phytoestrogens lower human fertility and sex drive. The "soyboy" claim.

Human studies on the effects of phytoestrogens are pretty lacking overall, but what does exist doesn't back up that claim-- because humans don't graze on red clover in west australia like a sheep. What that means is that it doesn't impact human fertility the way a terrified conservative brain stem thinks it does.

(ESPECIALLY not in a plate of soybeans, which has significantly lower levels of phytoestrogen than red clover.)

But what it DOES do is bind to the estrogen receptors in your body (and acts as a really good antioxidant but that's neither here nor there) which can mean it can act AS estrogen... or as an antagonist.

If you want to know more (especially if you have a background in chemistry, this source talks a lot about the structural similarities between estrogen and phytoestrogen and the mechanism of action) then go dive into PHYTOESTROGENS IN FUNCTIONAL FOOD by Fatih Yildiz, which collects together many of the studies that we do have on the matter and omits controversial ones.

(Plus it's an easy read for such a science-heavy publication imo)

Though I have to stress that my HRT guide is, y'know, fake cats! Nothing in nature replaces modern medicine***, but I wanted to make a good resource for WC fans with trans cats who wanted a little bit of scientific accuracy, wanted to cut herbs that cast Liver Failure 1000 on felines, and could reasonably be found in a temperate environment

***= Except medicinal maggots. Medicinal maggots are literally magical. Nothing debrides necrotic tissue like green bottlefly larvae and as far as I'm concerned they're the closest thing to divinity we have on this earth. And medicinal leeches I love you leeches im so sorry that anyone has ever called you a pest you're cherubic angels and she doesnt deserve this </3

After all I like. DO also care about scientific literacy #But it is funny to me that no one questions the comfrey LMAO #For context it's kind of like standing next to a nuclear reactor and then the audience points at a heavy object blocking a window and says- #''Hey isn't this a fire hazard?'' #Like. Good that you're familiar with fire code! There is something even worse in the room with us <3
