Haven't tried it myself, but there's also Hops (as in beer hops).

This option crossed my mind again as I can't help notice how unintentionally busty some regular (male) beer drinkers are at the local pub. lol

Swansons offers an extract called: Estro8PN Hop Extract ("powerful phytoestrogens that outperforms soy-derived phytoestrogens")

Alcohol by itself is a pretty powerful pro-aromatase...I think the hops may be just gravy compared to that, though craft brews have a lot more hops than Budweiser/Miller Lite/etc...

I read about this long ago around the time I was 21 and perhaps used it as a reason to drink regularly, and well it didn't do all that much for breast growth, I haven't masculinized much since I was 21 either...
