Which finding most strongly suggests testicular torsion over epididymitis?

• A. Relief of pain with scrotal elevation
• B. Absent cremasteric reflex on the affected side
• C. Fever and urinary symptoms
• D. Tenderness confined to the epididymis

Answer: (B)

The key point is the cremasteric reflex. Stroking the inner thigh normally causes the same-side testicle to rise due to a reflex arc involving the ilioinguinal and genitofemoral nerves. In testicular torsion, this reflex is typically absent on the affected side because the twisting of the spermatic cord disrupts the neural pathways and blood flow needed to trigger that contraction. Epididymitis, by contrast, does not involve acute cord twist, so the cremasteric reflex generally remains intact.

So, an absent cremasteric reflex on the affected side is the strongest clue pointing toward torsion rather than epididymitis. Other findings like fever and urinary symptoms, or tenderness confined to the epididymis, fit epididymitis, and relief with scrotal elevation is less reliable. This situation is a urologic emergency requiring prompt evaluation and management, often with Doppler ultrasound to assess blood flow and urgent surgical exploration if torsion is highly suspected.
