Topic - Bike seats and ED

needvert on 26 Jun 2012
As in erectile disfunction.

Been reading a bit, does anyone riding below 3 hours a week get it? Should I not care if I keep cycling to less than three hours? I notice one of the quotes below say there's a link between time on bike and ED - but it doesn't mention a lower limit.

Will 10 10minute rides a week put me much at risk?

Ahhh so many questions. I can only think of one way to test if there's a problem...It will make for an interesting diary.

I'll go get my bike fitted, still, am thinking about the noseless saddles. And padding the top tube...I've nutted myself more than a few times on that, stands to reason it's damaging!

Then there's the whole getting solid cardio will reduce risk of impotency, so a bit of cycling may net you better off! Even if the seat doesn't.

Yeah...I been thinking a lot about this. It's a scary notion to not be able to get it up.


Here's some various quotes from googling...

[1] This does not mean that people should stop cycling, Dr. Schrader said. And those who ride bikes rarely or for short periods need not worry.

[1] Researchers have estimated that 5 percent of men who ride bikes intensively have developed severe to moderate erectile dysfunction as a result...some experts believe that the numbers may be much higher...

[2] ...damage may become permanent if the tissues are continually damaged and not allowed to recover...

[2] ... nearly every cyclist who experiences erectile dysfunction or impotence will have symptoms before the problem becomes serious. Reduced blood flow to the perineum causes pain, numbness or tingling in the perineum long before men develop ED...

[3] "I don't think you can be a competitive rider and be protected from erectile dysfunction," says Goldstein.

[3] John M. Martinez, MD..."I wouldn't tell anyone to give up cycling because of fear of ED. If there is ED from cycling, it's almost always temporary and reversible..."

[3] One study in Germany found that oxygen levels in blood flow to the penis dropped by only about 20% when riders were on a no-nose seat. A traditional bicycle saddle reduces oxygen in blood flow by around 80%

[4] "Men should never ride bicycles. Riding should be banned and outlawed. It is the most irrational form of exercise I could ever bring to discussion." So says Dr Irwin Goldstein.

[4] ... demonstrated that when compared to
the general male population, cyclists were half as likely to suffer severe
impotence and 1/3 as likely to suffer any form of impotence. The conclusion he drew from the study is that cycling may not be as beneficial as swimming at mitigating or eliminating impotence. Also he concluded, at a minimum cycling does not expose riders to a higher risk of impotence...

[5] Research suggests that riding a bike for long periods can cause temporary erectile difficulties, explains "What to Do about Erectile Dysfunction," a new report from Harvard Medical School. The risk appears highest among men who cycle more than three hours a week.

[6] penile blood supply decreased significantly in 70% of the 40 cyclists who participated in the study...19% of the cyclists who rode their bikes more than 250 miles per week complained of erectile dysfunction.

[6] In a study of 463 cyclists competing in a long-distance cycling event (200 miles), perineal numbness during the ride was experienced by 31% of the cyclists and was associated with erectile dysfunction...

[6] 35 studies conducted...prevalence of moderate to severe erectile dysfunction in bicyclists was 4.2%, and that riding more than three hours per week was a risk factor for developing this condition.

[7] ...male cyclists riding in a 540-km race had a 13% incidence of difficulties with erectile function after completing the race.

[7] ...1,000 men in a bicycle riding club, 4.21% of whom experienced ED,
c o m p a red with 1.12% of the control population of male runners who experienced ED with no exposure to bicycle riding. It was also noted that bicycle-riding exposure (hours per week, miles per week, lifetime hours,
or lifetime miles) was directly correlated with the number of urologic complaints, including ED...
