Environmental Chemicals Are Feminizing Boys
Denmark has unveiled official research showing that two-year-old children are at risk from a bewildering array of gender-bending chemicals in such everyday items as waterproof clothes, rubber boots, bed linen, food, sunscreen lotion, and moisturizing cream. A picture is emerging of ubiquitous chemical contamination driving down sperm counts and feminizing male children all over the developed world. Research at Rotterdam's Erasmus University found that boys whose mothers were exposed to PCBs and dioxins were more likely to play with dolls and tea sets and dress up in female clothes. 'The amounts that two-year-olds absorb from the [preservatives] parabens propylparaben and butylparaben can constitute a risk for oestrogen-like disruptions of the endocrine system,' says the report. The contamination may also offer a clue to a mysterious shift in the sex of babies. Normally 106 boys are born for every 100 girls: it is thought to be nature's way of making up for the fact that men were more likely to be killed hunting or in conflict. But the proportion of females is rising. 'Both the public and wildlife are inadequately protected from harm, as regulation is based on looking at exposure to each substance in isolation, and yet it is now proven beyond doubt that hormone disrupting chemicals can act together to cause effects even when each by itself would not,' says Gwynne Lyons, director of Chem Trust.
