It’s theorised that too much time spent on a bike seat can cause slow, low-level trauma to perineal nerves, resulting in numbness in the short term and possibly erectile dysfunction long term.

Happy news for cycle fans though: it’s believed the key culprit may be the style of bike seat, and some new nose-less seats are now being designed to reduce perineal impact.
