What is Micro Trauma?
Biking on bumpy train shakes the bike seat which bumps into and causes micro-trauma to the testicular veins, vein valves, and supportive tissue. For this reasons alone, those with varicocele should avoid long distance biking on bumpy train.
Testicular Damage: Hyperthermia
Biking increases testicular temperature. High temperatures damage the testicles, and can completely stop sperm production!
Now, you might have been tempted to buy a nice cushion seat to prevent micro-trauma, but thick cushion seats trap heat and impair ventilation!
Every guy who bikes needs to account for proper heat ventilation.
Pressure & Varicocele Swelling Size
Biking is a unique form of exercise because it isolates and places large amounts of pressure in the lower torso. When exerting and pushing down on the peddle, you create high abdominal abdominal pressure. This leads leads to greater varicocele swelling.
This is more true for bikes with up-right sitting positions like most mountain bikes, and less true for more aerodynamic horizontal sitting positions like most racing bikes.
Advanced: Muscular Imbalances
To make matters worse, biking tightens up the muscles of the pelvic floor and is the cause of many muscular imbalances that are neither easily spotted nor corrected.
Biking should be treated as an advanced activity and should be done with the aid of proper guidance and education.
Biking is High Risk for Varicocele
In conclusion, biking should be considered a high-risk activity for varicocele. If you do have a varicocele, then you must take precautions before and during biking.
I go into great detail about how to make physical activity therapeutic for varicocele in the Varicocele Healing Guide.
