An orchiectomy is a surgical procedure to remove one or both testicles. Patient information: See related handout on testicular torsion, written by the authors of this article. While some studies report a high correlation of loss of cremasteric reflex and testicular torsion, there are a surprising number of studies reporting the persistence of the reflex during verified cases of torsion. The cremaster muscle is a paired structure made of thin layers of striated and smooth muscle. Typical imaging findings for ultrasonography and radionuclide imaging are shown in Table 1.
