The growing numbers of studies like this one are "compelling and should be a wake up call for policymakers," says Tracey Woodruff, director of the Environmental Research and Translation for Health Center at the University of California, San Francisco. More broadly, though, he acknowledges the field faces some huge challenges moving forward — especially as they try to draw a stronger link between these tiny particles and a decline in reproductive health or disease.
