Male Reproductive Health Disorders and the Potential Role of Exposure to Environmental Chemicals 2009

The report, written by Professor Richard Sharpe of the Medical Research Council and world leading expert on the issue, focuses on the deterioration of male reproductive health and role of exposures to hormone disrupting chemical.

Scientists now think that birth defects of boys’ genitals, low sperm counts and testicular cancer, collectively called Testicular Dysgenesis Syndrome, or TDS, can all have their origins during development in the womb. Testosterone, the male hormone, is needed to form a normal penis and to make the testicles ‘drop’ whilst the baby is in the womb. Many everyday chemicals in the environment or in consumer products have the potential to block the action of testosterone and exposure to this mixture of chemicals may undermine this process and harm future male reproductive health.

Widespread feminisation of male wildlife raises the alarm

This is the press release for the report below, 2008, which shows that male fish, amphibians, reptiles, birds and mammals have been harmed by chemicals in the environment. Widespread feminisation of male vertebrate wildlife is highlighted. 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.
