New Study Shows Roundup Damages Sperm
In the first study to measure the delayed effects of exposure to Roundup on sperm in mammals, the molecular biology department at the University of Caen, France, found that rats exposed to the glyphosate based pesticide Roundup altered testicular function after only 8 days of exposure at a concentration of only 0.5%. This concentration is similar to levels found in water after agricultural spraying.
Dr Séralini's team found that Roundup changed gene expression in sperm cells, which could alter the balance of the sex hormones androgen and estrogen. A negative impact on sperm quality was confirmed, raising questions about impaired sperm efficiency. The authors suggested that repeated exposures to Roundup at doses lower than those used in agriculture could damage mammalian reproduction over the long term.
The study’s findings should raise alarm in farm workers, as well as people who spray Roundup for municipal authorities and even home gardeners. People exposed to lower doses repeated over the long term, including consumers who eat food produced with Roundup and people who happen to be exposed to others’ spraying activities, should also be concerned.
