Cycling and erectile dysfunction: What the research actually shows

Cycling and erectile dysfunction (ED) are linked in some studies, but the evidence that cycling causes lasting ED is mixed. Saddle pressure on the perineum can cause temporary genital numbness, and a well-fitted bike and saddle are the main ways to reduce that pressure.

In a study of more than 2,700 male cyclists, genital numbness was common but wasn’t linked to worse erectile function scores (Baradaran et al., 2019). However, a meta-analysis of 6 studies found cyclists had about twice the odds of ED after adjusting for age and some health conditions. The authors called this limited evidence of a link, which doesn't show that cycling causes ED (Gan et al., 2021).

Does cycling cause erectile dysfunction?

Research hasn't established whether cycling causes erectile dysfunction. One large survey found cyclists had no worse erectile function scores than swimmers or runners (Awad et al., 2018), while a meta-analysis found higher odds of ED in cyclists once age and health were taken into account (Gan et al., 2021). For a wider look at what does and doesn't cause ED, Mojo's full guide to erectile dysfunction is a good place to start.

Differences in how much people ride, their bike setup, and who was studied may explain part of the mixed results. Cycling also brings real benefits for your heart and blood vessels, and good vascular health is part of what keeps erections working well in the first place.

What does the research actually say?

Two studies get cited the most, and they don't say the same thing.

Baradaran et al. (2019) surveyed 2,774 cyclists and measured their SHIM scores, a standard tool doctors use to rate erectile function. Overall, cyclists who reported numbness did not have worse SHIM scores than cyclists who didn't. The exception was numbness in the buttocks, which was linked to somewhat worse scores, while numbness in the penis, scrotum, or perineum was not (Baradaran et al., 2019).

Gan et al. (2021) took a different approach. Their meta-analysis pooled six studies covering 3,330 cyclists. The raw, unadjusted numbers showed no real difference between cyclists and non-cyclists.

Once the researchers adjusted for age and some health conditions, cyclists had about twice the odds of ED. That's an association, not proof that cycling causes ED, and factors the studies didn't measure could still play a part (Gan et al., 2021).

Those two findings are answering different questions. Baradaran's study says numbness by itself doesn't predict poor erectile function. Gan's meta-analysis suggests cycling may be linked to higher odds of ED once age and some health conditions are taken into account.

The practical takeaway is that cycling is not automatically safe or automatically risky. Bike fit, how much you ride, and your general health may all play a part.

The mechanism behind cycling-related genital numbness

Your body weight presses down through the saddle onto the perineum, the area between your legs where the pudendal nerve and artery sit close to the skin. Sustained pressure there may compress the nerve, the blood vessels, or both. How much depends on your anatomy, your saddle, and your riding position.

One small lab study of 40 healthy, athletic men found that blood supply to the penis dropped in over 70% of them while they cycled seated, but not while they stood on the pedals. In the same group, 61% reported genital numbness (Sommer et al., 2001). Because the group was small, that figure may not apply to all cyclists.

In a much larger survey of 2,774 cyclists, numbness was more common in people who rode more often, rode further, and had been cycling for more years (Baradaran et al., 2019).

Is genital numbness from cycling the same as erectile dysfunction?

No. They're different problems, though they may share some causes, like pressure on the nerves and blood vessels in the perineum. Having numbness doesn't automatically mean you have ED or will develop it. If you want a broader breakdown of what separates a physical cause from a psychological one, telling physical and psychological ED apart covers it in depth.

In plain terms, numbness is a pressure problem that bike setup changes can often ease. ED has many possible causes, and saddle pressure may be one of them for some cyclists. One doesn't automatically lead to the other.

Bike fit changes that may reduce numbness

Most of the fixes here are about your setup, not your effort. Small adjustments can change how much pressure lands on the perineum during a ride, and none of them require you to ride less or push harder.

Does saddle or handlebar position actually make a difference?

Yes, at least for numbness. In a large survey of cyclists, riders whose handlebars were level with or higher than the saddle had lower odds of genital numbness (Awad et al., 2018). No-nose saddles have the strongest evidence for cutting pressure on the perineum (Litwinowicz et al., 2021). For a wider look at prevention beyond cycling, see erectile dysfunction prevention.

Is ED from cycling permanent?

Research hasn't shown that cycling causes permanent ED. Gan's analysis found an association between cycling and ED based on limited evidence (Gan et al., 2021), which is one more reason to look after your bike fit and overall health.

Numbness often improves once the pressure is off, and bike setup changes can help prevent more of it. They can't guarantee that existing symptoms will clear, though. If numbness lasts, gets worse, or keeps coming back, see a doctor.

Warning signs that mean it's time to see a doctor

Numbness often clears up on its own. A few signs mean it's worth getting checked out instead of waiting it out:

• Numbness that doesn't go away after you stop riding
• Numbness that's getting worse over weeks or months, not better
• Any new or worsening erectile difficulty that shows up alongside the numbness
• Pain, not just numbness, in the saddle area

A doctor can check for nerve or circulation problems early. They can also check whether other health factors, like blood pressure or cholesterol, are playing a role. If you're unsure whether to book an appointment, talking to a doctor about ED walks through what that conversation usually looks like.

How a physical scare can turn into performance anxiety

Here's the part the research studies don't measure. A bout of numbness can worry you even after the numbness has gone, and that worry is where psychological erectile dysfunction often starts. You notice numbness, you wonder if it means something is permanently wrong, and the next time you're with a partner, you're checking in on your body instead of being present with them. That checking-in can make erections harder on its own.

Still, don't assume anxiety is the whole story. If erection problems carry on after a scare, see a doctor as well as working on the worry.

Dr. Shannon Chavez's credentials put her in a strong position to speak to this pattern. She's a licensed clinical psychologist, AASECT-certified sex therapist, and certified clinical sexologist, and she's built much of her work around exactly this kind of anxiety loop.

Mojo's own co-founder, Angus, has talked about going through this firsthand. A stretch of numbness after a long ride led to real worry, and that worry outlasted the numbness itself. Long after his body had recovered, the fear of it happening again was still showing up during sex. That's sexual performance anxiety in a nutshell: a physical scare that your mind keeps replaying long after your body has moved on.

The Erection Reset's approach to cycling-related performance anxiety

This exact pattern, a physical trigger turning into a lasting worry, is what The Erection Reset was built to address. The program doesn't diagnose or treat any underlying physical condition. It focuses on the anxiety loop that can take hold once you've had a scare, whether that scare came from cycling, a stressful period, or anywhere else.

The program uses evidence-based, expert-led techniques built around mindful practice, pelvic floor exercises, and breathing work, all aimed at helping you stay present with your body instead of monitoring it. Dr. Shannon Chavez, the psychologist behind the program, specializes in exactly this kind of performance anxiety and nervous system regulation.

If a health scare, on the bike or off it, has left you more anxious than the original issue deserved, that anxiety can be worked on, and The Erection Reset gives you a structured way to do it. You don't need to give up cycling to get there. You need a way to stop the worry from outlasting the ride.
