Human-made oestrogen is a group of synthetic compounds known as xenoestrogens that are found in many of the everyday products we use. These compounds are derived from a variety of sources, including industrial chemicals, pesticides, and pharmaceuticals. They are believed to have an effect on the endocrine system, potentially leading to health issues such as infertility, developmental disorders, and cancer. Xenoestrogens are structurally similar to natural estrogens and can bind to receptors in the body, disrupting the normal processes of the endocrine system. This can lead to a variety of health issues, including increased risk of some cancers, infertility, and reproductive disorders. They can also interfere with the development of the fetus in pregnant women and can cause adverse effects on the reproductive organs of both men and women. Xenoestrogens are found in a wide variety of everyday products, including plastics, cosmetics, cleaning products, pesticides, and food packaging. Exposure to these compounds is difficult to avoid, as they can easily leach into our food and water supplies. The effects of xenoestrogens on our health are not yet fully understood, and more research is needed in order to determine the long-term effects of exposure.
