Superficial reflexes are motor responses that occur when the skin is stroked. The cremasteric reflex is a superficial reflex found in human males that is elicited when the inner part of the thigh is stroked. Stroking of the skin causes the cremaster muscle to contract and pull up the ipsilateral testicle toward the inguinal canal. Like other superficial reflexes, it is simply graded as present or absent. A female counterpart of the cremasteric reflex is the Geigel reflex.
