In testicular torsion, which reflex is typically absent?

• A. Plantar reflex
• B. Patellar reflex
• C. Cremasteric reflex
• D. Pupillary reflex

Answer: (C)

In this scenario, the main idea is how a quick bedside test helps distinguish testicular torsion from other acute scrotal conditions. The cremasteric reflex is the brisk contraction of the cremaster muscle that pulls the testis upward when the inner thigh is stroked. This reflex relies on a neural pathway involving nerves that run with the spermatic cord. In testicular torsion, twisting of the cord disrupts blood flow and can impair the neural-muscular response, so the affected side often lacks this reflex. The absence of the cremasteric reflex on the involved side is a key clue that torsion may be present and needs urgent evaluation to prevent testicular loss. By contrast, the plantar and patellar reflexes are general spinal reflexes and are not altered specifically by testicular torsion, and the pupillary reflex is a cranial nerve–mediated response unrelated to scrotal conditions.
