"Researchers tested roundup on mature male rats at a concentration range between 1 and 10,000 parts per million (ppm), and found that within 1 to 48 hours of exposure, testicular cells of the mature rats were either damaged or killed. According to the study, even at a concentration of 1 ppm, the Roundup was able to affect the test subjects by decreasing their testosterone concentrations by as much as 35%."
