Pesticides are commonly used to protect the foods that we eat from insects and pathogens — but, according to a recent study in the journal Environmental Health Perspectives, they may also be destroying the vitality of sperm in the process. As American and Italian scientists demonstrated, there are two commonly used pesticides linked with plummeting sperm counts: organophosphates and N-methyl carbamates. The researchers analyzed the sperm concentration in men who work in agriculture and are therefore exposed to unusually large quantities of these chemicals, then compared them to the sperm concentrations of men with the least exposure.
“While there are likely many more contributing causes, our study demonstrates a strong association between two common insecticides — organophosphates and N-methyl carbamates — and the decline of sperm concentration," senior study author Melissa Perry, dean of the College of Public Health at George Mason University, told CNN.
