We used the ROC curve to define an interrupt SWE value that predicted decreased testicular echogenicity using average SWE values. The area under the curve for the UDT was 0.78 (95% CI: 0.70–0.85, sensitivity 83.7%, specificity 68.7%, p <0.001), with an average SWE value of 2.32 (m/s) for above the cut-off point indicates
