Cycling 'hits male fertility'.

KEEN male cyclists could be pedalling their way to infertility, scientists claimed yesterday.

Tests on Spanish triathletes found men who covered more than 200 miles a week on their bikes had "significant fertility problems".

Less than four per cent of their sperm were properly formed. And all 15 triathletes in the study had less than 10 per cent healthy sperm.

Study leader Professor Diane Vaamonde, from the University of Cordoba, told a conference in Amsterdam professional cyclists should freeze their sperm.

She said: "We think even people who are not professional but undergo high intensity or high volume cycling could also suffer from these changes."
