Men who take up cycling in an effort to stay fit, do their bit for the environment or avoid spiralling motoring costs, could be harming their health if they don't choose the right bicycle. That's the stark warning from consultant urological surgeon Mr Vinod Nargund from St Bartholomew's and Homerton Hospitals, London, in the urology journal BJU International.

He says that the problems to look out for include genital numbness, erection problems and soreness and skin irritations in the groin area.

Men who cycle a lot can also experience changes to their sperm function, because of the excessive heat generated in the pelvic area. No general link between cycling and male infertility has been established, but it is still recognised as a possible side effect and has been noted in a number of male cyclists.

Regular cyclists also run a higher risk of testicular damage and impaired testicular function.

Mountain bikers run a particular risk, says Mr Nargund, as studies have shown that they exhibit higher levels of scrotal abnormalities than on-road cyclists.

"The bicycle saddle is in direct contact with the perineum and its underlying structures" he explains. "It makes contact just behind the scrotum where the nerves and blood vessels enter the back of the scrotum and penis.

"This area is sensitive, with hair follicles and sweat and sebaceous glands, which are all good breeding grounds for infection.

"Abrasions, chafing, damaged hair follicles and bruising are among the most traumatic cycling injuries. Sweating in this area can also cause soreness and skin problems."

He points out that more than 60 per cent of male cyclists who have taken part in research studies have reported genital numbness.

"Numbness is common because the pressure of the saddle can impair the blood supply to this area and put pressure on the nerves in the penis" says Mr Nargund. "This can also affect the man's ab
