Pollution threatens male gender, says CHEM Trust report

By staff writers / HeraldSun, Australia

POLLUTION is damaging the "basic male tool kit", threatening the future of the male gender, according to new research.

A report released today by the charity CHEM Trust shows that male fish, amphibians, reptiles, birds and mammals have been harmed by man-made chemicals in the environment.

"These findings add to mounting worries about the role of hormone-disrupting or so-called ‘gender-bending' chemicals in the environment and the implications for human health," said charity CHEM Trust.

In mammals, genital disruption in males had been widely reported including: intersex features, small penis and testes, undescended testes; abnormal testes; or ambiguous genitals.

The report, which draws on more than 250 scientific studies from around the world, concentrates mainly on wildlife, identifying effects in a range of species.

"Males of species from each of the main classes of vertebrate animals (including bony fish, amphibians, reptiles, birds and mammals) have been affected by chemicals in the environment.

"Feminisation of the males of numerous vertebrate species is now a widespread occurrence. All vertebrates have similar sex hormone receptors, which have been conserved in evolution. Therefore, observations in one species may serve to highlight pollution issues of concern for other vertebrates, including humans," the report concludes.

My comment: Nature has a way of compensating for imbalances in the environment. But the question that leaps to my mind revolves around whether oversize SUVs, muscle cars and pickup trucks with huge wheels is a cause or an effect of the phenomenon.
