Xenoestrogens are a type of xenohormone that imitates estrogen.They can be either synthetic or natural chemical compounds.Synthetic xenoestrogens include some widely used industrial compounds, such as PCBs, BPA, and phthalates, which have estrogenic effects on a living organism even though they differ chemically from the estrogenic substances produced internally by the endocrine system of any ...
Xenoestrogens are xenohormones that mimic the effects of natural estrogen. When present in the body, xenoestrogens can bind with estrogen receptors in the brain, leading to a disruption in the gonadal endocrine system. Xenoestrogen exposure during different developmental periods can have differing effects on the reproductive system.
Endocrine disruptor chemicals (EDCs) are a type of chemical that directly influences sex hormones. [1] They have acquired these names due to the fact that they are anti-estrogens and anti-androgens. [1] By inhibiting the function of these hormones, fertility decreases, and an imbalance of such hormones has been shown to cause feminizing effects ...
[12] [13] [14] BPA is a xenoestrogen, exhibiting hormone-like properties that mimic the effects of estrogen in the body. [15] Although the effect is very weak, [16] the pervasiveness of BPA-containing materials raises concerns, as exposure is effectively lifelong.
A comparison of the structures of the natural estrogen hormone estradiol (left) and one of the nonyl-phenols (right), a xenoestrogen endocrine disruptor. Endocrine disruptors, sometimes also referred to as hormonally active agents, [1] endocrine disrupting chemicals, [2] or endocrine disrupting compounds [3] are chemicals that can interfere with endocrine (or hormonal) systems.

That includes a current or past hormone receptor-positive cancer (primarily breast and endometrial cancers), as well as a history of stroke, blood clots or cardiovascular disease, Barbieri explains.
The similarities, at molecular level, of an estrogen and a phytoestrogen allow them to mildly mimic and sometimes act as an antagonist of estrogen. [2] Phytoestrogens were first observed in 1926, [ 2 ] [ 5 ] but it was unknown if they could have any effect in human or animal metabolism.
Mycoestrogens mimic natural estrogen in the body by acting as estrogen receptor (ER) ligands. [8] Mycoestrogens have been identified as endocrine disruptors due to their high binding affinity for ERα and ERβ, exceeding that of well known antagonists such as bisphenol A and DDT. [10]
