![]() ![]() The cremaster muscle is a paired structure made of thin layers of striated and smooth muscle. The cremasteric reflex is most commonly performed in the evaluation of acute scrotal pain and the assessment for testicular torsion that is commonly associated with an apparent loss of the reflex. Similar to the other superficial reflexes such as the abdominal and the normal plantar reflexes the cremasteric reflex is not usually tested in contrast to the deep tendon, the brainstem, and primitive reflexes. In the female, it involves the contraction of muscle fibers along the upper part of the Poupart or inguinal ligament and is sometimes called the inguinal reflex. A female counterpart of the cremasteric reflex is the Geigel reflex. Like other superficial reflexes, it is simply graded as present or absent. Stroking of the skin causes the cremaster muscle to contract and pull up the ipsilateral testicle toward the inguinal canal. The cremasteric reflex is a superficial reflex found in human males that is elicited when the inner part of the thigh is stroked. Superficial reflexes are motor responses that occur when the skin is stroked.
