Holy Hormones Journal: Keep the weeds out of your lawn and and become infertile. Two for one. Roundup another – toxic endocrine disruptor. Another money maker for Monsanto – not to mention the IVF industry. Another effort at population control? No, you say – that is horrific. I say, think again.

The dirty truth about glyphosate, the active chemical in Monsanto’s Roundup herbicide formula, keeps rearing its ugly head, this time in a new study published in the journal Free Radical Medicine & Biology. According to this latest indictment of Roundup, researchers affirmed that Roundup is essentially a destroyer of fertility, particularly in men, and at levels far below what is commonly found as residue in the conventional food supply.
A team of scientists from the Universidade Federal de Santa Catarina in Florianopolis-Santa Catarina, Brazil, set out to verify the merits of an existing body of research on glyphosate, which has previously determined the chemical to be a powerful endocrine disruptor. They looked specifically at how exposure to low doses of glyphosate affects Sertoli cells, which live in the testicles, sustain healthy sperm, and are required for normal and healthy male sexual development.
As it turns out, when Sertoli cells are exposed to relatively low doses of glyphosate, they end up dying through a series of glyphosate-induced changes. According to the team’s analysis, Roundup exposure at a mere 36 parts per million (ppm), or 0.036 grams per liter (g/L), led to both oxidative stress and the activation of multiple stress-response pathways that ultimately led to Sertoli cell death in test mice. The herbicide also increased levels of intracellular calcium (Ca2+) in cells, an overload of which can also lead to cell death.
“Glyphosate has been described as an endocrine disruptor affecting the male reproductive system,” wrote the authors in their study abstract. “We could propose that Roundup toxicity, implicating in Ca(2+) overload, cell signaling misregulation, stress response of the endoplasmic reticulum and/or depleted antioxidant defense could contribute to Sertoli cell disruption of spermatogenesis that could impact male fertility.”
