In the presence of scrotal pain, an absent cremasteric reflex approaches 100% sensitivity for testicular torsion.

The cremasteric reflex is a contraction of the cremaster muscle, in response to the stroking of the thigh, which results in retraction of the testicle. Absence of the reflex is an ominous sign when assessing an acute scrotum.
