Global decline in male fertility linked to common pesticides

Researchers compiled, rated and reviewed the results of 25 studies of certain pesticides and male fertility and found that men who had been exposed to certain classes of #pesticides had significantly lower sperm concentrations. The study included data from more than 1,700 men and spanned several decades.

“No matter how we looked at the analysis and results, we saw a persistent association between increasing levels of insecticide and decreases in sperm concentration,” said study author Melissa Perry, who is an environmental epidemiologist and the dean of the College of Public Health at George Mason University.

The new analysis focuses on two groups of chemicals — #organophosphates and some #carbamates — that are commonly used in #insecticides.
