These compounds can cause endocrine disruption by multiple mechanisms including acting directly on hormone receptors, affecting the levels of natural hormones in the body, and by altering the expression of hormone receptors. [1] [2] The most commonly occurring xenohormones are xenoestrogens, which mimic the effects of estrogen.
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 ...
Bisphenol A is an endocrine disruptor that can mimic estrogen and has been shown to cause negative health effects in animal studies. Bisphenol A closely mimics the structure and function of the hormone estradiol by binding to and activating the same estrogen receptor as the natural hormone.
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.

Consumer products such as toys and cosmetics may contain phthalates or parabens, which disrupt androgen synthesis. [1] [2] Phthalates are mainly found as softeners in plastics, but also perfumes, nail varnish and other cosmetics. Fetuses that are exposed to a mixture of phthalates in utero may show signs of disrupted reproductive development.
A phytoestrogen is a plant-derived xenoestrogen (a type of estrogen produced by organisms other than humans) not generated within the endocrine system, but consumed by eating plants or manufactured foods. [1] Also called a "dietary estrogen", it is a diverse group of naturally occurring nonsteroidal plant compounds that, because of its ...
Phthalates, substances categorized as "forever chemicals," have been found in nearly every American's bloodstream, coming from the cleaning products they use to the food and drinks they consume.
