Pesticide impairs male reproductive function

According to the May issue of the journal Epidemiology, high levels of DDT found in some Mexican workers suggest that pesticide can impair male reproductive function. The human body metabolises DDT to DDE. An international team of researchers took blood samples from 24 men aged 16 to 28 who had not been exposed to DDT in their work. In these men the high DDE levels correlated to low leve...
