Testicular torsion: A medical emergency

Testicular torsion most commonly affects boys aged 10-18 and requires emergency medical attention. Local data shows that on average more than one boy or young man loses a testicle each month in mid and south Essex due to delayed arrival at hospital.

Testicular torsion happens when a testicle rotates, twisting the spermatic cord that brings blood to the scrotum. This cuts off the blood supply to the testicle and surrounding tissue, causing sudden pain and swelling.

Key facts:

• Causes sudden, severe pain in one testicle
• Can occur during activity, after injury, or during sleep
• Requires immediate visit to A&E - don't wait. Go straight to Southend or Broomfield Hospital A&E departments if possible. (Basildon Hospital can also assess for testicular torsion, but you would be transferred to Broomfield Hospital for specialist treatment if required.)

Why quick action is required:

Testicular torsion is a medical emergency. The longer the blood supply is cut off, the greater the risk of permanent damage:

• Within 6 hours: Good chance of saving the testicle
• After 12 hours: Risk of damage increases significantly
• After 24 hours: Testicle will likely need to be removed

Remember: Sudden, severe testicular pain means go straight to A&E or call 999.
