Why Testicles Hurt After Running

Running is a fantastic form of exercise that can provide numerous physical and mental health benefits. However, it’s not uncommon for runners, particularly men, to experience testicle pain after a run. As someone who has been an avid runner for years, I can personally attest to the discomfort and concern that can arise from this post-run symptom. In this article, we will delve into the various reasons why testicles may hurt after running and share some tips on how to alleviate this discomfort.

1. Testicular Trauma

One of the most obvious causes of testicle pain after running is direct trauma or injury to the testicles. While it may seem improbable, accidental contact with objects such as exercise equipment, branches, or even the ground can occur during a run. Even a slight impact can lead to pain and discomfort. The best way to prevent this type of injury is by wearing supportive underwear, such as a jockstrap, which can provide an extra layer of protection for the testicles.

2. Testicular Torsion

Testicular torsion is a more serious condition that can cause severe testicle pain after running. It occurs when the spermatic cord, which provides blood flow to the testicles, becomes twisted, cutting off the blood supply. This condition requires immediate medical attention, as it can lead to permanent damage if left untreated. If you experience sudden and intense testicular pain, accompanied by nausea or vomiting, seek medical help immediately.

3. Varicocele

A varicocele is a condition characterized by enlarged veins in the scrotum. While it may not directly cause testicle pain, the increased blood flow and pressure can lead to discomfort during physical activities such as running. If you notice persistent pain or swelling in your testicles after running, it’s advisable to consult with a healthcare professional who can diagnose and provide appropriate treatment, if necessary.

4. Muscle Strain

Just like any other muscles in the body, the muscles surrounding the testicles can also be strained during running. This can result in testicle pain that is more of a dull ache or soreness. Taking breaks in between runs, practicing proper warm-up and cool-down exercises, and ensuring you have the right running form can help prevent muscle strain and reduce testicle pain.

5. Hydration and Chafing

Dehydration and chafing in the groin area are two common issues that can contribute to testicle pain after running. When the body becomes dehydrated, it can lead to muscle cramps and discomfort, including in the testicles. Similarly, friction and chafing caused by clothing can irritate the sensitive skin in the groin area. Staying well-hydrated and wearing moisture-wicking, supportive underwear can help alleviate these issues.


Experiencing testicle pain after running can be concerning, but it’s important to remember that in many cases, it is temporary and not a cause for alarm. It’s always a good idea to listen to your body and seek medical advice if the pain persists or is accompanied by other alarming symptoms. By taking preventative measures, such as wearing supportive underwear, staying hydrated, and practicing proper running form, you can reduce the likelihood of experiencing testicle pain after your runs. Happy running!
