A comprehensive analysis of 20 studies from around the world found that exposure to some insecticides is associated with lower sperm concentration in men, according to a recent study published in Environmental Health Perspectives.
In short:
- The study links lower sperm concentrations to two classes of commonly used insecticides.
- Sperm concentration is an important indicator of overall health, and low concentrations are linked to higher rates of some cancers and shorter life expectancy.
- Sperm concentrations have decreased dramatically globally over the past decades.
Key quote:
“Health-protective policy and engineering solutions are needed now to reduce exposures… and prevent continued male reproductive harm.”
Why this matters:
Despite significant reproductive health concerns, the use of pesticides is widespread, making environmental exposure common. The international decline in average sperm concentrations poses a serious risk to human fertility, underscoring the urgent need for policy and regulations that reduce these exposures.
