Method
The patient lies on a couch. The examiner gently stretches the right spermatic cord using the thumb and index finger right about the testis in the right scrotum. For a patient with appendicitis, this causes pain in the right iliac fossa.{{cite journal |last1=Rastogi |first1=Vaibhav |last2=Singh |first2=Devina |last3=Tekiner |first3=Halil |last4=Ye |first4=Fan |last5=Mazza |first5=Joseph J. |last6=Yale |first6=Steven H. |title=Abdominal Physical Signs and Medical Eponyms: Part II.

The sensitivity and specificity of the Ten Horn's sign is unknown.
