Xenoestrogen

Meaning

A xenoestrogen is a type of exogenous compound, meaning it originates outside the body, that mimics the molecular structure and biological activity of endogenous estrogens, thereby acting as an endocrine-disrupting chemical (EDC). These compounds are found widely in the environment, including plastics, pesticides, and industrial chemicals, and they can bind to and activate estrogen receptors in human and animal tissues. Their presence is a clinical concern due to their potential to disrupt normal hormonal signaling and contribute to reproductive and metabolic dysfunction.
