What they found was striking: almost all the studies reported a decrease in sperm concentration; decreased motility was also reported though less frequently; while morphological changes were not strongly associated in studies—only two indicated any changes to sperm shape.
These findings build on a growing body of evidence that pesticide exposure at environmental or occupational levels diminished sperm health.
These results might not be surprising as sperm production is regulated by the endocrine system, a highly sensitive system of hormone regulators.
The study highlights the importance of generating strong pesticide regulations that incorporate endocrine disruptors for worker protection from pesticide exposure. With endocrine disruptors, it is only low levels of exposure that is required to severely threaten human and animal reproductive and hormonal functioning.
