A #phytoestrogen is a plant-derived xenoestrogen (see estrogen) not generated within the #endocrine system, but consumed by eating phytoestrogenic plants. Also called a "dietary estrogen", it is a diverse group of naturally occurring #nonsteroidal plant compounds that, because of its structural similarity with estradiol (17-β-estradiol), have the ability to cause estrogenic and/or antiestrogenic effects.[1] Phytoestrogens are not essential nutrients because their absence from the diet does not cause a disease, nor are they known to participate in any normal biological function.[1]
Its name comes from the Greek phyto ("plant") and estrogen, the hormone which gives fertility to female mammals. The word "estrus" - Greek οίστρος - means "sexual desire", and "gene" - Greek γόνο - is "to generate". It has been hypothesized that plants use a phytoestrogen as part of their natural defence against the overpopulation of herbivore animals by controlling female fertility.[2][3]
