Where does the myth come from?
The concern that cycling causes impotence is not new. As early as the 1990s, initial reports emerged suggesting that pressure on the perineum – the area between the genitals and anus – could affect nerves and blood vessels. The result, it was claimed, was numbness or even erectile dysfunction.
However, this theory was often exaggerated at the time. Today we know that the problem is not cycling itself , but rather incorrect seating positions, unsuitable saddles, or too much pressure in one area .
What science says about it
The research is mixed: there are reports of nerve irritation caused by cycling, as well as large studies that find no permanently increased risk of erectile dysfunction from cycling .
As early as 1997, Andersen & Bovim described cases of numbness and temporary erectile dysfunction in a study of long-distance amateur cyclists, which the authors attributed to nerve compression from saddle pressure. The study documents that perineal nerve irritation can occur during very long stages—but it refers to isolated cases and not a general epidemic.
However, larger, more modern datasets provide reassuring results: The multinational cross-sectional study by Awad et al. (2018) found no general association between cycling and poorer sexual or urological function compared to runners and swimmers; however, some specific genital complaints (e.g., urethral strictures or transient numbness) occurred more frequently with certain cycling styles. The study also emphasizes that factors such as seat position and handlebar height have an influence.
The “Cycling for Health UK” analysis by Hollingworth, Harper & Hamer (Observational Study) comes to a similar overall finding: regular cycling was not clearly linked to an increased rate of ED, infertility or prostate cancer ; however, the authors discuss possible mechanisms (repetition trauma, inflammation, pressure) and recommend further investigations in cases of very high weekly volume.
Medical portals and experts summarize it as follows : Erectile dysfunction is generally explained by vascular diseases, diabetes, high blood pressure, medications, or psychological factors—not primarily by sports such as cycling. At the same time, urologists and sexual medicine specialists emphasize that perineal discomfort and temporary numbness should be taken seriously because they indicate local pressure problems that can usually be resolved through ergonomic adjustments.
The scientific consensus is largely: those who cycle regularly are doing their body (and their potency) a favor – as long as they pay attention to ergonomics.
The real problem: pressure sores and numbness
What can actually occur is temporary numbness in the genital area . This is a warning sign that the pressure on the perineum is too great.
Causes:
-
Saddle too narrow or too hard
-
Incorrect seating position (leaning too far forward)
-
Lack of breaks or excessively long sitting times
The good news is that these symptoms usually disappear once the pressure is reduced or the seating position is adjusted.
This is how you protect yourself – and remain productive
The risk can be minimized with a few simple measures:
1. The right saddle
Choose an ergonomic saddle that fits your pelvis and has a cutout in the perineal area . Many modern road bike saddles are specifically designed to prevent pressure points.
2. Check seating position
An excessive bend in the pelvis or handlebars that are too low lead to unnecessary pressure. A professional bike fitting analysis can work wonders here.
3. Regular changes of position
Riding in a standing position , briefly standing up, loosening up – all of this relieves the perineum and promotes blood circulation.
4. The right cycling shorts
Cycling shorts with a high-quality chamois pad are essential. They distribute pressure evenly and reduce friction.
5. Listen to your body's signals
Numbness is not taboo, but a signal. Anyone experiencing regular symptoms should take them seriously – and, if necessary, speak to a urologist or sports medicine specialist.
What cycling has to do with sexual health
Cycling not only strengthens legs and lungs – it also improves overall vascular health . Good blood circulation is crucial for a stable erection.
Furthermore, regular exercise reduces the risk of obesity, high blood pressure and diabetes – all factors that can actually contribute to erectile dysfunction .
In other words, cycling protects potency – it does not endanger it.
Conclusion: The myth persists – but it is false.
No, cycling does not cause impotence. It is one of the healthiest forms of endurance training – for the heart, circulatory system, and sexual function alike.
Those who pay attention to the saddle, posture and breaks have nothing to worry about.
Or to put it provocatively: The only thing that gives out when cycling is the battery – not the rider. 😉💪🏼
