Fish becoming transgender from contraceptive pill, chemicals being flushed down household drains

A fifth of male fish are now transgender because of chemicals from the contraceptive pill being flushed down household drains, a study by has suggested. Male river fish are displaying feminised traits and even producing eggs, the study found. The chemicals causing these effects include ingredients in the contraceptive pill, by-products of cleaning agents, plastics and cosmetics, according to the findings. More than 200 chemicals from sewage plants have been identified with oestrogen-like effects and drugs such as antidepressants are also altering fish’s natural behaviour, his study found. “Other research has shown that many other chemicals that are discharged through sewage treatment works can affect fish, including antidepressant drugs that reduce the natural shyness of some fish species, including the way they react to predators,” Professor Tyler said. click here to read the story 19:55
