These problems can all stem from the pressure from the bike's saddle.
But a US scientist has designed a special saddle which prevents cyclists suffering saddle-related problems.
Recent research found a link between cycling and reduced blood flow leading to erectile dysfunction in male cyclists.
The US National Institute for Occupational Safety and Health studied policemen who rode bikes as part of their job and found the pressure from bicycle saddles may lead to health problems.
Dr Roger Minkow, an ergonomics expert, has now developed a range of specially designed saddle with the company Specialized
The central section of the BG saddles has been removed so there is no pressure against the pudendal nerves and blood vessels where the saddle and rider come into contact.
Impotence
There is also padding where the bony parts of bottom meet the saddle.
Previous research found cycling could be linked to problems with impotence in men.
It was found having a narrow, unpadded seat caused a significant reduction in blood flow in the arteries of the penis.
Cyclists were also found to have higher rates of impotence than swimmers.
A further study found regular cycling affected impotence, and could lead to difficulty achieving orgasm, prostate pain, difficulty urinating as well as pain and numbness in the saddle area.
