%X Estrogen is a hormone, which is produced in ovary and testis; however, it has many biological effects besides the reproductive system. Phytoestrogens are the compounds, which have estrogen-like structure and activities, taking place in structure of various edible plants at different levels and in different compositions. These compounds attracted notice after the first quarter of 20th century upon they had been associated with infertility seen in some of animals fed with alfalfa, and these compounds have been identified in human-derived biological samples and its effects on health have been taken under study in the recent 30 years. These materials have especially antioxidant role in plants while they have activities in animals and humans as estrogen agonist and antagonists. Based on their chemical structure, they may be gathered under especially isoflavon and lignan groups while some of members of coumestan and stilbene groups are also identified as phytoestrogenic compound.
