Prehn's sign is important in the diagnosis of testicular torsion. As part of the differential diagnosis of acute scrotum, differentiate testicular torsion from epididymitis.

Execution
We lift the patient's testicles. Examination:
 * in case of testicle torsion – will cause worsening of pain,
 * in epididymitis – leads to a slight reduction in pain.
