I know you can get estrogen from horse urine as a feedstock, but there are other methods used today, right? Do they use other animal products? Petroleum? I'm just looking for a basic overview and don't know where else to look.

You can run an ethical femboy milk farm. This won’t get you any estrogen, but you can do it.
Mostly it’s still horse pee, pig ovaries, and you can do it with yams, as well as cholesterol, although that yields the least result, something like less than 4%
Yams!!
And I imagine the cholesterol also comes from animal sources? Or is it from yeast? 4% sounds low, but then again you gotta grow an entire pig/horse to get it otherwise.
Karl Djerrasi, who first synthesized oral contraceptives, set up shop in Mexico City because it was close to a good source of wild yams.
