Xenoestrogens have been implicated in a variety of medical problems, and during the last 10 years many scientific studies have found hard evidence of adverse effects on human and animal health. [33] There is a concern that xenoestrogens may act as false messengers and disrupt the process of reproduction.
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.
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]

Estrogen (also spelled oestrogen in British English; see spelling differences) is a category of sex hormone responsible for the development and regulation of the female reproductive system and secondary sex characteristics.
When it comes to our exposure to various chemicals—”glyphosate, BPA, heavy metals, xenoestrogens, endocrine-disrupting chemicals, and so on,” according to RFK Jr.’s list of infertility ...
There are two different forms of the estrogen receptor, usually referred to as α and β, each encoded by a separate gene (ESR1 and ESR2, respectively).Hormone-activated estrogen receptors form dimers, and, since the two forms are coexpressed in many cell types, the receptors may form ERα (αα) or ERβ (ββ) homodimers or ERαβ (αβ) heterodimers.

The relationship between the environment and sexual orientation is a subject of research. In the study of sexual orientation, some researchers distinguish environmental influences from hormonal influences, [1] while other researchers include biological influences such as prenatal hormones as part of environmental influences.
