During the preschool examination of a 4-year-old boy, you are unable to palpate his testes within the scrotal sac. his parents state that previous exams have been normal, and that

testes are clearly visible during baths                                              

Explanation:

            Parents of a 4 year old boy claims that the boys testicles are clearly visible while taking bath but when at the pre-school examination, the examiner cannot feel the boys testes in the scrotal sac because of the cold hand of the examiner or the chilly examination hall must have activated the cremasteric reflex of the child.

           The cremasteric reflex is a reflex found in males which is elicited with the touch of a cold hand or stoke in the inner thighs. During this, the cremasteric muscles contract and pull the testes up into the inguinal canal.
