The Erection Hardness Score (EHS) and the Sexual Health Inventory for men (SHIM) are patient-reported outcome scoring systems for erectile function. It is unclear which is more reliable for predicting the objective erectile function.
The aim of this study was to evaluate whether the EHS could predict objective erectile function by measuring the maximal penile circumferential change (MPCC) with an erectometer.
The study included 98 patients who visited our clinic from 2005 to 2010. The erectile function was evaluated using the SHIM, EHS, and MPCC. The MPCC was measured with the largest circumferential change of three consecutive occurrences of nocturnal penile tumescence (NPT) determined using the erectometer.
We defined erectile dysfunction (ED) as MPCC < 20 mm and carried out multivariate analysis using logistic regression analysis to clarify the predictors for ED, with the variables including age, the SHIM score, and the EHS. We compared the tendency for MPCC ≥ 20 mm when EHS was 3 or more with that when EHS was 2 or less.
The median age of the patients was 59.5 years (range 18-83). In logistic regression analysis, the EHS was the only predictor for ED with MPCC < 20 mm. The mean EHS in the MPCC < 20 mm group was 1.64 ± 0.20 (mean ± SEM) and that in the MPCC ≥ 20 mm group was 2.46 ± 0.13 (P = 0.0018). There was a correlation between the EHS and the MPCC (correlation coefficient = 0.33). In comparison with the group having an EHS of 2 or less, that with an EHS of 3 or more tended to have MPCC ≥ 20 mm (P = 0.013).
The EHS was correlated with the MPCC. The EHS represents the objective erectile function shown by the measurement of NPT.
勃起硬度评分（EHS）和男性性健康问卷（SHIM）是用于评估勃起功能的患者报告结局评分系统。目前尚不清楚哪种方法更能准确预测客观勃起功能。
本研究旨在通过使用勃起测量计测量最大阴茎周径变化（MPCC），评估 EHS 能否预测客观勃起功能。
本研究纳入了 2005 年至 2010 年间在我院就诊的 98 例患者。使用 SHIM、EHS 和 MPCC 评估勃起功能。使用勃起测量计测量三次夜间阴茎勃起（NPT）中最大周径变化得出 MPCC。
将 MPCC＜20mm 定义为勃起功能障碍（ED），采用逻辑回归分析进行多变量分析，以明确 ED 的预测因素，变量包括年龄、SHIM 评分和 EHS。我们比较了 EHS 为 3 或更高与 EHS 为 2 或更低时 MPCC≥20mm 的趋势。
患者的中位年龄为 59.5 岁（范围 18-83 岁）。在逻辑回归分析中，EHS 是 MPCC＜20mm 的唯一 ED 预测因素。MPCC＜20mm 组的平均 EHS 为 1.64±0.20（平均值±SEM），MPCC≥20mm 组的平均 EHS 为 2.46±0.13（P=0.0018）。EHS 与 MPCC 呈正相关（相关系数=0.33）。与 EHS 为 2 或更低的组相比，EHS 为 3 或更高的组 MPCC≥20mm 的趋势更大（P=0.013）。
EHS 与 MPCC 相关。EHS 代表通过 NPT 测量显示的客观勃起功能。
