If your suntan oil can change the sex of fish, what can do it to you?

Spare a thought for the male hornyhead turbot. For despite its name, it is changing gender. And the sunscreens that symbolise bronzed sex appeal may be partly to blame.

Scientists have found that male hornyhead turbot and English sole, feeding near sewage outfalls on the Californian coast, are being feminised - and a chemical found in sunscreens is the likely culprit.

Meanwhile, Swiss researchers have found other suspected gender-bender chemicals from sun creams and oils building up in fish in their rivers.

A similar study by the Southern California Coastal Water Research Project found fish affected all along the coast. The American research is the first to find sex changes in fish in the open ocean.
