“Even when we evaluated in our study lower exposure, we saw an association between people’s exposure to PFAS and fertility. This is very alarming,” she added.

People are considered to have infertility after a year of trying to become pregnant by natural means and having no success. Study participants with PFAS in their blood had a tougher time conceiving. (…)
