Cycling may lead to erectile dysfunction as sitting on the saddle could be crushing your private parts, which means the pressure is falling on your nerves of your private parts. This can cause erectile dysfunction as it is not favorable for your fertility health.
During cycling, the seat puts constant pressure on the perineum, the area between the genitals and anus. This pressure can harm nerves and temporarily slow down blood flow. This can cause tingling or numbness in the penis and may eventually lead to erectile dysfunction as well.
