Know the Signs
Testicular torsion is a medical emergency. The faster you act, the better the outcome. This page exists so you know exactly what to look for — and what to do.
The Time Window
Approximate testicle salvage rates based on time from onset of symptoms to surgery.
What Actually Happens
The spermatic cord — the cord that carries blood to the testicle — twists on itself. When it twists, blood flow is cut off completely.
Without blood, the testicle begins to die. This process starts within hours. After 4–6 hours, the chance of saving the testicle drops dramatically. After 12–24 hours, it may be impossible.
The only fix is surgery. A doctor must untwist the cord and secure both testicles to prevent it from happening again.
Symptoms to Watch For
These can come on suddenly — even during sleep. If you have any of these, go to the ER immediately.
Sudden severe pain
Sharp, intense pain in one testicle that comes on fast. This is the most common and most important symptom.
Scrotal swelling
The scrotum may become swollen, red, or tender to the touch within minutes to hours.
High-riding or tilted testicle
One testicle may appear higher than normal or sit at an unusual angle due to the twisted cord.
Nausea and vomiting
The severity of the pain often causes nausea or vomiting — a sign the body is in serious distress.
Abdominal pain
Pain can radiate into the lower abdomen, which sometimes causes people to mistake it for a stomach issue.
Frequent urination
Some people experience an increased urge to urinate alongside the other symptoms.
If you have any of these symptoms — especially sudden severe pain — go to the emergency room immediately. Do not wait.
Who Is at Risk
Testicular torsion can happen to any male at any age — but some factors increase the likelihood.
Age 12–25
Most common in teenage males and young men, though it can occur in newborns and older adults too.
Bell clapper deformity
A condition where the testicle is not properly attached inside the scrotum, allowing it to rotate freely. Many people don't know they have it.
Previous torsion
If you've had torsion before and it was not surgically corrected, you are at high risk of it happening again.
Family history
Bell clapper deformity can run in families, which may increase risk for brothers and sons.
Cold temperatures or physical activity
Torsion can be triggered by physical activity, injury, or even cold temperatures — but it can also happen with no trigger at all.
What to Do If You Think It's Torsion
Do not wait
Do not wait to see if the pain goes away. Do not take pain medication and go to sleep. Every minute matters.
Tell someone immediately
Tell a parent, guardian, coach, or anyone nearby. You need to get to an ER — don't try to drive yourself if the pain is severe.
Go to the emergency room
Not urgent care. Not a walk-in clinic. The emergency room. Tell them you think you have testicular torsion. Use those exact words.
Expect an ultrasound
The ER will likely do a scrotal ultrasound to check blood flow. If torsion is confirmed — or even strongly suspected — surgery will happen fast.
Surgery is the only fix
The surgeon will untwist the cord and stitch both testicles in place to prevent future torsion. Recovery is typically 1–2 weeks.
