So, I always wondered what I would do if the Apocalypse broke out and all estradiol medication was gone.
I thought that maybe drinking the urine of pregnant mares would do the trick, but you’d die of overhydration long before you could get proper levels. However, it turns out that, similar to the production of Premarin, you could use the urine to make estrogen cheese. 
Unfortunately, I don’t really like cheese. So I’d be screwed either way 
This is fucking awesome research, thanks for sharing. I'm now going to become a RETVRN guy but we need to RETVRN to roving bands of nomadic transfem horse archer pastoralists
There's a researcher that I know that is going through and resurfacing a lot of shit like western historians gendering people as male eunuchs when they referred to themselves as female. This happened a lot with the Galli, Syrians, and Scythians
Kim Stanley Robinson's Years of Rice and Salt leaned into this really hard. it follows a group of characters that reincarnate in different historical periods. you follow them by their first name's letter. one is trans, finding out after becoming a eunuch (but in a non consensual way). the character finally feels normal afterwards.
then after that she always reincarnates as a cis woman which is pretty cool. she has to do some trippy afterlife journey to claim her true gender
That book is such a trip in general. The overall premise is "what if the Black Death wiped out 99% of Europe instead of just 40-50%, and then China became the dominant global and colonial power?" It's an interesting thought experiment.
i have a soft spot for it. only thing is i wish the little self contained short stories were longer. especially the time period with the Iroquois taking in Japanese refugees and in turn being educated by them to rapidly industrialize. that by itself could be it's own novel
and it's the Iroquois Federation that becomes the superpower in the end. and communist. but only because of the big war
There's also plants with estrogenic effects. Anise oil comes to mind, it is considered safe for flavoring, and people did manage to hugely increase its potency.
Sounds more appetizing than the urine cheese but I’m not sure if the effect is strong enough, and the stuff in the link is definitely way beyond what a bunch of queer horse riders in antiquity could do.
Breene et al. in 1965 had demonstrated salt absorption in cheese, when curd is submerged in brine. In this alternative hypothesis curd, contained within a horsehair or cloth bag, is submerged in warm pregnant mare urine, within a buried clay pot. This is just a variation of buried clay pot irrigation which has been known for over 2100 years. Clay pots could be buried singly or as a group within a small depression. It could then be intermittently refreshed with warm urine from nearby tethered pregnant mares. One mare can daily produce between 7.6 to 11.9 litres of urine. The pot’s aperture could be covered with a large cloth. This, fixed in position by pegs, would absorb the urine and preferentially drain it into it by placing a small stone placed over each clay pot’s aperture, causing a further depression. The curd, having absorbed oestrogens, is then extracted and prepared as cheese for storage and later ingestion.
The "recipe" if anyone is curious.
