Preliminary research shows that testosterone levels were significantly lower in men who lived in homes with high concentrations of flame retardants in house dust than those in homes with low levels of the chemicals in the dust. Known as PDBE’s, flame retardants are long-lasting in the environment and have been found to mimic estrogen and interfere with testosterone. Flame retardants are found in plastic electronic equipment and upholstery fabrics.
The research was conducted on men who go to infertility clinics. Levels of testosterone were 15 percent lower in men who showed high concentrations of PDBE’s.
