ABSTRACT：Objective To analyze the application value of penile vibrating perception threshold measurement in the diagnosis of erectile dysfunction （ED） and provide reference for the seversity of ED  patients.Methods The clinical data，Erectile Hardness Scale （EHS） score，International Index of Erectile Function Questionnaire-5 （IIEF-5） score，and the vibrating perception threshold （VPT） of the penis of 257 patients with decreased erectile function as the main complaint or accompanying symptoms treated during Jan. and Dec.2021 were retrospectively collected and analyzed.Patients with EHS=4 and IIEF-5≥22 were classified into the normal group，and the rest into the ED group.The differences in VPT in patients with different EHS scores were compared，and the correlation between IIEF-5 and VPT was analyzed.The diagnostic value of VPT for ED was evaluated with receiver operating characteristic （ROC） curve.Results The difference in penile VPT among patients with different EHS scores was statistically significant （P＜0.05）.With the decrease of EHS score，VPT showed an increasing trend.Glans VPT was negatively correlated with IIEF-5 score （ρ=-0.2 P＜0.001），and penile shaft VPT was also negatively correlated with IIEF-5 score （ρ=-0.26，P＜0.001）.The VPT of glans penis [（4.17±1.37）V vs.（3.47±1.24）V，P=0.009] and the VPT of penis body [（3.73±1.41）V vs.（2.99±1.14）V，P=0.003] in the ED group were both higher than those in the normal group.The area under the ROC curve （AUC） of the glans VPT was 0.642.When the cut-off value was 3.537 V，the sensitivity was 63.4%，and the specificity was 63.6%.The AUC of the penile shaft VPT was 0.659.When the cut-off value was 2.775 V，the sensitivity was 72.3%，with a specificity of 54.5%.Conclusion The penile VPT of ED patients is higher than that of normal ones，and there is a correlation between VPT and the severity of ED.Severe ED is associated with higher VPT.The measurement of penile VPT is helpful for the clinical diagnosis of ED patients.
