Santa Clara, CA – A recent investigation has detected glyphosate, the main ingredient in Monsanto’s Roundup, in human sperm, raising alarming questions about the weed killer’s potential role in infertility. The study, published in Ecotoxicology and Environmental Safety, revealed that over 55 percent of sperm samples from a French infertility clinic contained elevated glyphosate levels. This finding suggests that glyphosate might impair sperm DNA and contribute to reproductive issues.
The research, titled “Glyphosate Presence in Human Sperm: First Report and Positive Correlation with Oxidative Stress in an Infertile French Population,” analyzed samples from 128 male patients aged 26 to 57 at the Pole Santé Léonard de Vinci medical center, located in France’s agriculturally intensive “bread basket” region. This area, known for its extensive use of Roundup, ranks among the highest in pesticide purchases in France.
Findings showed that 73 of the 128 men had glyphosate in their seminal plasma, with levels nearly four times higher than those found in their blood. Researchers observed a significant positive correlation between glyphosate levels and oxidative stress—a condition that damages cells and organs by disrupting the balance of free radicals and antioxidants. This oxidative stress is linked to reduced male fertility by affecting sperm vitality and functionality.
Moreover, the study points to glyphosate’s potential disruption of the Blood-Testis Barrier, which could lead to the production of anti-sperm antibodies and autoimmune responses, further compromising male fertility.
Head researcher Claudine Vasseur from the Centre de Fertilité Vasseur emphasized the implications of these findings, stating, “Our results suggest a detrimental effect of glyphosate on human reproductive health and potentially on future generations.” She advocates for a precautionary approach by European authorities in regulating glyphosate and glyphosate-based herbicides (GBHs), emphasizing the need for further investigation to safeguard human health.
The researchers expressed concern over the impact of glyphosate on reproductive systems and recommend that regulators exercise increased caution until additional studies can confirm these results.
