Unregulated chemicals in everyday items such as toothpaste, soap, and deodorant could be causing fertility problems for men, a new study suggests. Parabens such as methylparaben and propylparaben are preservatives widely used in U.S. grooming products. To examine the effects of these chemicals on fertility, researchers in Poland studied the lab test results of 315 male fertility clinic patients, reports Reuters.com. They found that those with higher concentrations of parabens in their saliva, blood, urine, and semen had lower testosterone levels and a larger proportion of sperm that was abnormally shaped or slow moving—factors that reduce the likelihood of fertilization. Parabens were also linked to DNA damage in men’s sperm. The researchers remain unsure why the chemicals may affect fertility, or at what levels they can be harmful—but urge caution all the same. Study leader Joanna Jurewicz says avoiding parabens altogether would be “very difficult, because they are widespread,” but suggests checking labels on personal care products to limit consumption where possible.
