New research shows that when mothers are exposed to some pesticides and chemicals during pregnancy, male offspring are born with smaller penises and feminized genitals. Chemicals used in some food wrapping, cosmetics, baby powders and flame retardants have been found to interfere with male hormones in vertebrate animals, including humans. "This research shows that the basic male tool kit is under threat," says Gwynne Lyons, who wrote the report published by the charity CHEMTrust, which drew on more than 250 scientific studies.
