A third of male fish in English rivers are changing sex due to 'gender-bending' pollution, alarming research shows.
Experts say female hormones from the contraceptive pill and HRT are being washed into our rivers and causing male fish to produce eggs.
The problem - which is country-wide - has raised fears that the pollutants could also be contaminating our drinking water - and even be affecting the fertility of men.
The Environment Agency study looked at the health of more than 1600 roach found in 51 rivers and streams around the country.
Overall, a third of the male fish were between sexes. However, in one waterway, near a particularly heavy discharge of treated sewage more than 80 per cent had female characteristics.
Tests showed the males developed female sex organs and were producing eggs. Such fish also produce less sperm and the sperm that is produced is of low quality. Females may also be affected, producing abnormal eggs..........
