Another important point is that trans women typically start on an antiandrogen as well as an estradiol supplement. Testosterone's effects are orders of mag stronger than estrogen, so trans women typically have to take drastic measures to significantly reduce testosterone first so the estrogen can work, such as taking large amounts of spironolactone or cyproterone acetate or orchiectomy; without these measures, estrogen isn't nearly as effective. You don't exactly see much spironolactone in the water supply! (Personal anecdata)
