A 21-year-old male asked:

Can you explain the cremasteric reflex used to rule out torsion and can ice be used to test this reflex?

Specializes in Pediatric Urology
Cremasteric reflex: Is reflex contraction of cremaster muscle. Develops early, is maximal between ages 5 - 10 years, then wanes.Can pull testis into groin.Occurs if inner thigh or scrotum is touched or subject thinks he will be touched.Used to rule out torsion because spermatic cord is twisted & will not respond with reflex.Not 100% reliable if torsion is only 180degrees. Ice cube to thigh or scrotum can test reflex.
