"Many agricultural pesticides – including some previously untested and commonly found in food – disrupt male hormones, according to new tests conducted by British scientists. The researchers strongly recommended that all pesticides in use today be screened to check if they block testosterone, which is critical to men’s and boys’ reproductive health. Thirty out of 37 pesticides tested by the University of London altered male hormones, including 16 that had no known hormonal activity until now. Most are fungicides applied to fruit and vegetable crops, including strawberries and lettuce. 'This study indicates that, not surprisingly, there are many other endocrine disruptors that we have not yet identified or know very little about,' said Emily Barrett, a University of Rochester scientist who was not involved in the study. The findings come as the EPA faces opposition from the pesticide industry after expanding its Endocrine Disruptor Screening Program, which requires testing of about 200 chemicals found in food and drinking water to see if they interfere with estrogen, androgens or thyroid hormones."
