Phytoestrogens sometimes called "dietary estrogens" are a diverse group of naturally occurring non steroidal plant compounds that because of their structural similarity with estradiol (17β-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 s… (More on Phytoestrogens)
