Contraceptives, cleaning products and other household items flushed down drains and toilets are turning male fish transgender.
Chemicals in these substances work on the fish in a similar way to the human hormone oestrogen leading to creatures with both female and male characteristics
The chemicals, which are affecting as many as one in five male river fish, can lead to a reduction in sperm production as well as triggering the production of eggs.
Experts from the University of Exeter found that 20 per cent of freshwater fish at 50 different sites in the UK had higher feminine characteristics.
They also found that the offspring of these fish tended to be more susceptible to chemical alteration.
The chemicals causing these effects are often flushed down the loo and include ingredients in the contraceptive pill, and by-products of cleaning agents, plastics, and cosmetics.
