Abstract：
To explore the efficacy, in terms of sensitivity and specificity, of Erection Hardness Score (EHS) applied to masturbation in diagnosing predominantly organic erectile dysfunction (ED), compared to the actual standard, which is nocturnal penile tumescence and rigidity (NPTR).
A total of 189 consecutive patients who came to our outpatient clinic from October 2019 to October 2020, reporting ED and an abridged International Index of Erectile Function (IIEF-6) score <26 were enrolled. Patients filled out two psychometric questionnaires: the IIEF-6 applied to partnered intercourse and the EHS applied to masturbation, then they underwent the NPTR test with Rigiscan for 2 consecutive nights in good sleep condition. Sensitivity, specificity, positive predictive value, and negative predictive value of EHS and IIEF-6 scales with NPTR as the standard, as well as the correlation between EHS, IIEF-6, and NPTR results were calculated.
Results show that the sensitivity of the EHS scale for the diagnosis of ED was 60.0%, the specificity was 95.7%, the positive predictive value was 83.3%, the negative predictive value was 86.9%, and the coincidence rate was 86.2%. The correlation coefficient was 0.572 and the area under the ROC curve was 0.78, which means the strength of erection in masturbation as evaluated by the EHS can effectively help in discriminating between predominantly organic and apparently nonorganic ED.
An EHS score of 3-4, meaning good-optimal erectile function during masturbation, decreases the likelihood of predominantly organic ED and reduces the need for further NPTR testing.

摘要：
目的：探讨疗效，在敏感性和特异性方面，EHS应用于手淫诊断主要是器质性ED，与实际标准相比，这是NPTR。
方法：共纳入2019年10月至2020年10月到我们门诊就诊的189名连续患者，报告ED和摘录的国际勃起功能指数（IIEF-6）评分<26。患者填写了两份心理测量问卷：IIEF-6适用于伴侣性交，EHS适用于手淫，然后，他们在良好的睡眠状态下连续2个晚上接受了Rigiscan的NPTR测试。灵敏度,特异性，正预测值，以NPTR为标准的EHS和IIEF-6量表的阴性预测值，以及EHS之间的相关性，计算IIEF-6和NPTR结果。
结果：结果显示EHS量表诊断ED的灵敏度为60.0%，特异性为95.7%，阳性预测值为83.3%,阴性预测值为86.9%，符合率为86.2%。相关系数为0.572，AUC为0.78，这意味着EHS评估的手淫勃起强度可以有效地帮助区分主要是有机和明显的非有机ED。
结论：EHS评分为3-4，意味着手淫期间的最佳勃起功能，降低了主要有机ED的可能性，并减少了进一步NPTR检测的需要。
