More than 55% of sperm samples from a French infertility clinic contained high levels of glyphosate, the world’s most common weedkiller, raising further questions about the chemical’s impact on reproductive health and overall safety, a new study found.

The new research also found evidence of impacts on DNA and a correlation between glyphosate levels and oxidative stress on seminal plasma, suggesting significant impacts on fertility and reproductive health.
Taken together, our results suggest a negative impact of glyphosate on human reproductive health and possibly on progeny,” the authors wrote.
The paper comes as researchers look for answers to why global fertility rates are dropping, and many suspect exposure to toxic chemicals like glyphosate is a significant driver of the decline.
Glyphosate is used on a wide range of food crops and in residential settings in the US. The most popular glyphosate-based product is Monsanto’s Roundup weedkiller, which has been at the center of legal and regulatory battles in recent years. US government research from 2023 found genotoxicity in farmers with high levels of the herbicide in their blood, suggesting an association between it and cancer.
In December, a group of top US public health advocacy groups petitioned the Environmental Protection Agency to ban the product, though its defenders have said there is no definitive proof of its toxicity to humans. Still, dozens of countries have banned or restricted its use.

The levels French researchers found in sperm were four times higher than in the men’s blood, which the authors wrote is the first time the comparison had been made. They called the finding “worrying”, and it suggests the chemical is particularly dangerous for reproductive systems.
Oxidative stress “is considered to be one of the most important factors in male fertility by regulating the vitality and functionality of mammalian spermatozoa”, the authors wrote, and they found a “significant positive correlation” between stress and glyphosate levels.
Agricultural workers recorded the highest glyphosate levels, and 96% of farmers included in the study had at least some. A landscaper also showed among the highest levels, and smokers typically had elevated levels much higher than those who did not smoke. Eating organic produce did not have a clear impact on levels.
The study’s authors wrote it “would be wise for regulators to apply a precautionary principle” in regulation, which means erring on the side of caution to protect human health until further research can be done to confirm the problems identified in the study.

Dang, so not even organic products can mitigate or prevent the consumption and absorption. That leads me to believe that consistent consumption of antioxidants and detoxing are seemingly the only ways to address this?
No small concern that organic may be contaminated regularly with pesticide drift. It’s damn well disconcerting to have glyphosate becoming ubiquitous. F Bayer-Monsanto. The Nazi eugenics as far as I am concerned never stopped post WWII.
There are studies that have established a clear link between glyphosate and celiac disease. Based on this study, it can be conjectured that exposure to glyphosate in men maybe the reason for higher prevalence of celiac disease in infants of these men. It could well be the hypothesis for another reasearch study.
