more random interesting things
apparently phytoestrogens are not the only kind of sex hormone produced by plants, phytotestosterone also exists.
here is the study that talks about it
there are enough interesting tid-bits in the study that it's worthwhile to read fully, even without biology or chemistry training.
Of particular note, one of the plants the scientists found testosterone in was, ironically, the soybean (which is known for containing phytoestrogens). If the whole "soy boy" nonsense wasn't bullshit before, it's definitely bullshit now
