Phytoestrogens, sometimes called "dietary estrogens", are a diverse group of naturally occurring non steroidal plant compounds that, because of their structural similarity with estradiol (17-β-estradiol), have the ability to cause estrogenic or/and antiestrogenic effects. Their name comes from phyto = plant and estrogen = estrus (period of fertility for female mammals) + gen = to generate. The similarities, at molecular level, of estrogens and phytoestrogens allow them to mildly mimic and… (More on Phytoestrogens)
