Endocrine-disrupting chemicals are substances that may interfere with normal hormone signaling.
Researchers have studied common exposures, including BPA-related chemicals, phthalates, PFAS, parabens, PCBs, and persistent pollutants, in relation to reproductive health. A 2025 systematic review found that these exposures were associated with changes in hormone measures, semen quality, ovarian reserve, infertility-related outcomes, PCOS, and assisted-reproduction outcomes. https://www.mdpi.com/2075-1729/15/7/993
A 2024 systematic review and meta-analysis reported positive associations between exposure to phthalates, cadmium, and BPA and nonalcoholic fatty liver disease. The study reported pooled odds ratios of 1.18 for phthalates, 1.37 for cadmium, and 1.43 for BPA. https://www.sciencedirect.com/science/article/pii/S1043661824001968?via%3Dihub
Here are the different mechanisms mentioned in the studies
Hormone-receptor interaction: Some chemicals can bind to or block hormone receptors, potentially changing cellular signals normally controlled by hormones.
Hormone production and metabolism: EDCs may influence how hormones are synthesized, transported, broken down, or cleared.
Thyroid signaling: Certain environmental chemicals can interfere with thyroid-hormone pathways, which are important for metabolism and development.
Epigenetic regulation: During sensitive developmental windows, exposures may alter gene-regulation processes without changing the DNA sequence itself.
Oxidative stress and inflammation: Some EDCs have been studied in relation to reactive oxygen species, mitochondrial function, inflammatory signaling, and metabolic disruption
Five Everyday Habits for Lower-Exposure Living
1. Do not heat food in plastic. Use glass or ceramic for microwaving and hot leftovers
2. Choose fresh food more often. Cook at home when possible, and reduce dependence on highly packaged or canned foods.
3. Clean the dust. Damp-wipe surfaces, wet-mop floors, and wash hands before meals.
4. Simplify personal-care products. Use fewer products and favor fragrance-free options.
5. Know your water. Review local water-quality information and use a properly selected filter when it is appropriate.
