Does Cycling cause Erectile Dysfunction?
If you sit on your bike for long periods of time, the seat puts pressure on your perineum, an area between your anus and penis. The perineum is filled with arteries and nerves that supply oxygen-rich blood and sensation to your penis.
For a man to have an erection, nerves signal blood vessels to relax and increase blood flow through the arteries into the penis. If there are any problems with the nerves, blood vessels this may result in erectile dysfunction
Over the last few decades, researchers have discovered that some male cyclists develop damage to the pudendal nerve, the main nerve in the perineum, and the pudendal artery, which sends blood to the penis.
