Key Takeaway:
- The best place to put your balls when cycling is on a properly fitted saddle that supports your sit bones—not your soft tissue.
- Correct bike fit, saddle design, compression shorts, and riding posture can prevent numbness, pain, or long-term issues.
- Research confirms that positioning, saddle geometry, and cycling gear—not cycling itself—determine comfort and genital health.
Wondering where to put your balls when cycling? It’s a question many male cyclists ask when they experience pain, numbness, or discomfort on longer rides.
Cycling offers fitness, freedom, and adventure, but if your genitals aren’t positioned correctly on the saddle, you may end up with scrotal compression, numbness, or saddle sores.
The good news is that with the right setup and riding habits, you can stay comfortable and safe while enjoying the ride.

Cycling and Genital Health: Myth vs Reality
Some claim that cycling leads to erectile dysfunction, infertility, or other reproductive health issues. But what does the research really say?
- In one study, researchers investigated the relationship between long-distance cycling and the occurrence of erectile dysfunction. According to the study, cyclists on a long-distance rides can decrease the risk of erectile dysfunction by riding a road bike instead of a mountain bike, keeping the handlebar height lower than the saddle height. They should also use a saddle without a cutout if they experience perineal numbness.
- Another study published in 2014 on Research Gate aimed to examine if there is a link between urogenital abnormalities in men and regular cycling. The study concluded that there is no causal relationship between the amount someone cycles, ED, and infertility.
- Other studies suggest that keeping handlebars lower than the saddle and using proper saddle types reduces pressure on sensitive areas.
Bottom line: Cycling itself isn’t inherently harmful to male genitals—but improper scrotal positioning and bike fit are.
What the Research Says About Scrotal Positioning
Proper positioning means sitting so that the sit bones carry the saddle pressure, while the penis and scrotum rest naturally without being compressed. If the scrotum is pressed directly against the saddle, it signals poor bike fit or the wrong saddle design.
- Compression problems: Urogenital problems in cyclists, including genital numbness from nerve entrapment, are reported in 50–91% of riders. These issues are directly related to perineal pressure and saddle design (Leibovitch et al., 2005).
- Scrotal temperature: Moderate cycling raises scrotal temperature, which may affect testicular function, but this is a separate issue from positioning (Jung et al., 2008).
- Gear innovations: Some cycling shorts and bibs now include pouches designed to hold the genitals in place for improved comfort and reduced friction.
- Expert advice: Most bike fit experts and coaches recommend adjusting the saddle angle and height to ensure the sit bones—not soft tissue—carry your weight.
Common Cycling Pain and Problems
Genital Numbness
Excessive pressure on nerves and arteries in the groin can cause numbness. If this happens, adjust your saddle tilt and switch positions frequently.
Genital Pain
Often linked to pudendal nerve compression, this pain can be reduced with padded shorts and a properly fitted saddle.
Saddle Sores
These painful lesions appear in areas where your body comes in contact with the saddle. These can last up to a week.
Chafing
Chafing is another common problem. This type of skin irritation usually occurs when two parts of your skin rub against each other. The friction caused by cycling can create a lot of heat, irritating the skin and leading to chafing.
Crotch Rot (Jock Itch)
A fungus causes crotch rot, also known as jock itch or tinea cruris. This fungal infection usually occurs in warm, moist areas, like your groin, and between your legs.
Where to Put Your Balls When Cycling
The following tips will help you keep your boys happy and safe while cycling:
Invest in the Right Saddle
The saddle you choose for your bike is the most important part of cycling. Be sure to get a saddle that is comfortable and supportive. As much as possible, choose a broader saddle, as this can better absorb bumps when cycling.
You can also try gel-filled saddles. These provide more cushioning and comfort than regular saddles.
Adjust the Height of Your Handlebar
Research shows that handlebar and saddle position directly affect pressure distribution. If your genitals feel compressed, tilt the saddle slightly downward and ensure handlebars are adjusted for your torso length.
Sit the Right Way
CDC explains that the best way to maintain proper genitalia health during cycling is by sitting on your sitz bone. The sitz bone is the lowermost section of your pelvic bone, which you can feel when pressing down against it. Position yourself in the saddle so that you balance your weight evenly in the saddle and not on the soft genital area.
Change Your Position While Cycling
The best way to avoid saddle soreness or pain while cycling is to shift your weight often. Doing so prevents too much pressure from building up in one area and prevents numbness.
Use Compression Clothing
Compression shorts and bibs can hold the scrotum securely in place, reducing bounce and pressure. (See our detailed guide on cycling bibs vs shorts)
Use Shorts with Padded Crotch
Wearing padded shorts when cycling can be very beneficial. The padding will reduce friction and pressure in the genital area while also providing extra comfort. Choose one made with comfortable, soft, and durable materials that can wick away or absorb moisture.
How To Prevent Saddle Sores
If you often find yourself battling saddle sores, consider these tips:
Use Chamois Cream
Lubricating between your skin and your shorts can help prevent saddle sores. You can rub the cream on your chamois and skin for protection.
Use Chaffing Gel
You can use anti-chafing gels to prevent skin rubbing on skin or skin rubbing on clothing. This forms a silky protective surface on the skin to reduce friction.
Stop Hair Removal
Shaving your nether region can damage the epidermis. This puts you at risk of hair follicle infections and ingrown hairs. Can’t help but shave, epilate or avoid using depilatory creams? Use a light layer of antibiotic ointment after hair removal sessions.
Extra Tips for Comfort & Performance
- Check your bike fit annually to prevent chronic issues.
- Rotate between different saddle types if you ride daily.
- Train smart: Improve cycling speed and endurance without sacrificing comfort.
- Don’t ignore other body parts—knee pain, for example, is common (is cycling bad for knees?).
- Urban rider? Equip yourself with the essential urban biking list.
FAQ: Quick Answers for Male Cyclists
Does cycling cause erectile dysfunction?
No. Poor bike fit and prolonged pressure—not cycling itself—cause problems.
Where exactly should the scrotum rest when cycling?
The scrotum should rest naturally against the body, not compressed against the saddle. Your sit bones should take the pressure.
What saddle is best for men?
A saddle that supports sit bones, with a cut-out or gel padding if needed for comfort.
How do I stop my balls from going numb while riding?
Adjust saddle tilt, change position frequently, and wear padded compression shorts.
Conclusion
Where to put your balls when cycling comes down to proper posture, saddle choice, and the right gear. By ensuring your sit bones carry the load—not your scrotum—you can ride comfortably, prevent numbness, and avoid long-term issues. Protecting your “boys” means you’ll enjoy cycling for fitness, adventure, and fun without discomfort.
