As a vegetarian (and consumer of soy milk) for 28 years I can tell you it did pretty much zero for my hormone levels. Ditto flax seeds, green tea, spearmint tea, saw palmetto, red clover, etc, etc. Yes, they may have a small amount of antiandrogen or phytoestrogen but compared to what hormones can accomplish their effects are negligible/zero. Seriously don't waste your time and money.
