Pesticides are killing our sperm
Killing bugs and sperm at the same time.
Pesticides, which are well known to have caused spectacular declines the world over in bees, birds, and other wildlife, are also taking a heavy toll on the virility of men.
A new study found that the agricultural poisons are reducing the quality and quantity of sperm in men all over the globe, with farm workers bearing the brunt of the sexual desecration. George Washington University researchers pored over 17 scientific studies that were published between 2007 and 2012 and reported in the journal Toxicology that 15 of them found “significant associations between exposure to pesticides and semen quality indicators.”
In addition to the U.S. findings, studies conducted on French, New Zealander, Indian, Tunisian, and Israeli men have all found decline in sperm count. Some studies record a drop by approximately 50 percent between 1940 and 1990, no small amount.
These results might not be surprising as sperm production is regulated by the endocrine system, a highly sensitive system of hormone regulators. A study on Mexican workers in the floral industry, where workers are routinely exposed to organophosphate, finds that workers not only have increased levels of testosterone, but also suppressed levels of follicle stimulating hormone and inhibin b, which are two sensitive markers for sperm production.
So go organic and save humankind’s ability to reproduce.
