Causes
By Mayo Clinic staff
Testicular torsion occurs when the testicle rotates on the cord that runs upward from the testicle into the abdomen (spermatic cord). This rotation twists the spermatic cord and reduces blood flow. If the testicle rotates several times, blood flow to it can be entirely blocked, causing damage more quickly.
Males who get testicular torsion have an inherited trait that allows the testicle to rotate freely inside the scrotum. About one in 10 males is at risk of testicular torsion because one or both of the testicles aren't securely attached to the inside of the scrotum. This inherited condition often affects both testicles.
In men and boys who are at risk of testicular torsion, the condition often occurs with no apparent trigger. Signs and symptoms of testicular torsion may start following:
- Physical activity
- An injury to the scrotum
- Sexual arousal or activity
- Sexual arousal or reflexes during sleep
- Exposure to cold weather
