The three most important details to obtain are the patient’s age, the description of the pain and a sexual history.8 No single factor in the history can reliably distinguish torsion.
Age
As shown in table 1, different age groups make certain diagnoses more likely. Testicular Torsion has a bi-modal distribution typically presenting in neonates and post puberty. Appendiceal torsion is more common in pre-pubertal boys.

12-16 | 52% | 32% | 3% | 13% |

Testicular Torsion can present at any age but is less common in the elderly.
