Male cyclists risk sexual problems if they don’t choose the right bike

08.07.2008
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 ability to get an erection.

“There is a greater incidence of numbness and erectile problems in men who cycle regularly and over longer training distances. That is why it is important to rest intermittently during prolonged and vigorous cycling.”

Choosing the right bike is essential, stresses Mr Nargund.

“The male cyclist should know his bicycle well and a proper fit is particularly important for high-performance cycling” he says.

“The level of pedal resistance is also very important, because riding a bike using too much resistance is a major cause of health problems in the groin area.

“Cyclists can also help to ease saddle-related injuries or skin irritations by adjusting the saddle height and fore and aft position.

“Padding in the saddle and shorts are also important if cyclists want to avoid saddle-related problems.”

Mr Nargund’s comment piece has been published online on the BJU International website in advance of its hard copy publication later this year.

Im Focus: Junior scientists at the University of Rostock invent a funnel for light

Together with their colleagues from the University of Würzburg, physicists from the group of Professor Alexander Szameit at the University of Rostock have devised a “funnel” for photons. Their discovery was recently published in the renowned journal Science and holds great promise for novel ultra-sensitive detectors as well as innovative applications in telecommunications and information processing.

The quantum-optical properties of light and its interaction with matter has fascinated the Rostock professor Alexander Szameit since College.

Im Focus: Stem Cells and Nerves Interact in Tissue Regeneration and Cancer Progression

Researchers at the University of Zurich show that different stem cell populations are innervated in distinct ways. Innervation may therefore be crucial for proper tissue regeneration. They also demonstrate that cancer stem cells likewise establish contacts with nerves. Targeting tumour innervation could thus lead to new cancer therapies.

Stem cells can generate a variety of specific tissues and are increasingly used for clinical applications such as the replacement of bone or cartilage....
