There are a number of factors that can increase your risk of erectile dysfunction.
And a common question that we get as Urologists are, 'Does bicycling actually increase your risk of having problems with erections.' And the short answer is, 'Yes.' Depending on the types of seats you're using, things like that. But basically bicycling puts direct pressure from the bicycle seat on and area called the perineum.
The perineum is the area behind the testicles and in front of the rectal area. And that is where all the nerves and the blood vessels that go to the penis go through to get to the penile area. So by placing direct pressure on that area, there can be trauma or injury to some of those nerves or blood vessels. And for this reason, in the recent years, bicycle companies have come out with newly developed seats that actually are split down the middle so that pressure is no longer placed on this middle area and rather distributed to the sides.
And that can be protective to reduce the risk of injury to those areas. But, if your an avid biker and you spend a lot of time on the bike then you should definitely consider getting one of these specialized seats, otherwise there can be trauma that occurs as a result of long hours spent on the bike.
