Linear regression models were used to assess the relationships between the urinary concentrations of twenty-five chemicals and serum sex hormones in men of reproductive age. To normalize the data prior to conducting subsequent regression modeling, a natural logarithm (ln) transformation was applied due to the skewed distribution of these twenty-five chemicals and sex steroid hormones. Monthly expenses for take-out food were documented to calculate the potential exposure to chemicals from disposable food packaging13. Assessing exposure to EDCs through the detection of human-excreted environmental endocrine disruptors or their representative metabolites is highly feasible compared with that of assessing exposure from sources and routes. The body reacts to soy isoflavones, mainly genistein and daidzein, in complex ways. USDA guidelines strictly prohibit hormone use in organic beef production . Tests show hormone-treated beef contains 1.2 nanograms of estrogen per serving, while untreated meat has 0.85 nanograms . We used estradiol-17β, progesterone, and testosterone, along with synthetic variants like zeranol and trenbolone acetate . Consumers should look for certifications that ensure fish were raised without hormones, antibiotics, or synthetic pesticides . These hormones stay detectable in soil for three months after treatment stops . Hormone residues escape from hatchery ponds into wastewater and affect human health through endocrine system disruption . 17α-methyltestosterone use in fish farming disrupts the endocrine system . These compounds bind to hormone receptors, altering how your body produces and uses testosterone. Long-term exposure may impair testosterone production and reproductive health. They disrupt thyroid function and reduce testosterone levels—especially in older adults with prolonged exposure. They bind to hormone receptors, block testosterone signaling, and accumulate in body fat over time. Originally marketed for fighting germs, triclosan also disrupts thyroid hormones and testosterone. Studies show they may reduce testosterone levels and negatively impact male reproductive function. People who eat microwave popcorn daily show 63% higher PFAS levels in their blood samples over a year . Many manufacturers now provide BPA-free options due to health concerns. Canned pasta and soups have shown the highest concentration levels . Fermented soy products might be even better because they’re easier to digest . Over 50 hormones have been identified in humans and other vertebrates. Hormones act as chemical messengers that are released into the blood stream to act on an organ in another part of the body. The endocrine disruptors in your environment are outside your direct control in many ways. Finally, support your body's detoxification capacity through healthy nutrition, regular movement, adequate sleep, and stress management. Next, reduce secondary exposures by choosing fragrance-free products, reducing receipt handling, and minimizing plastic bottle use. There are hundreds of substances suspected of being endocrine-disrupting chemicals (EDCs). They are also known as endocrine-disrupting chemicals or EDCs. The endocrine system is a network of glands that produces all the hormones used by the body. In 2020, the EU published their Chemicals Strategy for Sustainability which is concerned with a green transition of the chemical industry away from xenohormones and other hazardous chemicals. In 2013, a number of pesticides containing endocrine disrupting chemicals were in draft EU criteria to be banned. While the Food Quality Protection Act only required the EPA to screen pesticides for potential to produce effects similar to estrogens in humans, it also gave the EPA the authority to screen other types of chemicals and endocrine effects. TBT has been shown to impact invertebrate and vertebrate development, disrupting the endocrine system, resulting in masculinization, lower survival rates, as well as many health problems in mammals. The chemicals occur in plastics, pesticides, food containers, children's toys, industrial waste, and some personal care products which can enter and accumulate in the environment by contaminating the soil, air, and water. Toxicology research shows that some endocrine disruptors target the specific hormone trait that allows one hormone to regulate the production or degradation of intrinsic hormones. The endocrine system secretes hormones in response to environmental stimuli and to orchestrate developmental and reproductive changes. These findings may provide insights for future longitudinal epidemiological investigations and experimental studies. These EDCs are present in everyday life in the form of various consumer products, and several epidemiological investigations have detected EDCs in humans4,5,6. One study reported that the sperm concentration in men in Western countries declined by approximately 50–60% between 1973 and 2011. Several studies have shown a significant decline in sperm quantity and quality in men over the past few decades. The mixture effect analyses using the WQS and BKMR models further confirmed that BP3, MECPP, and MECOP were the most highly weighted chemical mixtures. However, considerable scientific uncertainty remains regarding the actual causes of such effects.
