Researchers from France published a study in the journal Ecotoxicology and Environmental Safety revealing that three out of five sperm samples collected from a French infertility clinic showed high levels of glyphosate, the world's most commonly used weedkiller. "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," reported The Guardian (United Kingdom) about the paper.
