Nail polish and other household objects could be causing fertility problems, according to a new Duke University and Harvard University study.
Researchers at the two universities found that flame retardant chemicals in common products, such as nail polish and upholstered furniture, could pose risks to women's fertility.
The study showed increased exposure to these chemicals was linked to adverse results in In Vitro Fertilization, which is when an egg is fertilized outside of the body.
Researchers took the archived urine samples of 211 women who had participated in IVF treatments and analyzed them for concentrations of organophosphate flame-retardants, called PFRs.
According to the study, the more a woman had been exposed to these chemicals, the less likely she was to have successful embryo implantation, fertilization, pregnancy and live birth.
