Contraceptive pills and chemicals in cleaning products that are flushed down toilets and drains are turning male fish into female fish, new research has shown. According to the study, the remnants of cleaning products, chemicals and of contraceptive pills have been giving male fish female characteristics.
A new study carried out by leading fish biologist, Professor Charles Tyler from the University of Exeter, has found that one in five male river fish are being affected. The study found that some male river fish are displaying a reduced sperm quality and some males are even producing eggs.
The chemicals in the contraceptive pill, by-products of cleaning products, plastics and cosmetics, are responsible for this. “We are showing that some of these chemicals can have much wider health effects on fish we expected,” Said Tyler.
