A xenohormone is a type of chemical compound that mimics the action of natural hormones in the body. These substances can be synthetic or naturally occurring and are often associated with endocrine disruption.
Characteristics of Xenohormones:
- Mimic Natural Hormones: They can bind to hormone receptors in the body, mimicking the effects of endogenous hormones.
- Endocrine Disruptors: Many xenohormones are known to interfere with the normal function of the endocrine system, potentially leading to health issues.
- Sources: Common sources of xenohormones include industrial chemicals, pesticides, plasticizers, and compounds found in personal care products.
Examples of Xenohormones:
- Xenoestrogens: These mimic estrogen and are found in substances like Bisphenol A (BPA), phthalates, and certain pesticides.
- Xenoandrogens: Compounds that mimic or interfere with androgens (male hormones).
- Xenoprogestogens: Substances that mimic or interfere with progestogens.
Health Implications:
- Reproductive Issues: Xenohormones can disrupt reproductive health by mimicking or blocking natural hormones.
- Cancer Risk: Exposure to xenohormones like xenoestrogens has been linked to an increased risk of hormone-related cancers.
- Developmental Problems: Exposure during critical developmental periods can lead to long-term health effects.
