Objective measurements of sexual arousal in men most commonly involve monitoring changes in penile size. Although changes in circumference are most often used, volumetric changes have been reported to be more sensitive and thus more effective. Six men volunteered to observe an erotic videotape while circumferential and volumetric changes of their penises were recorded. The two measures were significantly correlated (r = .68) but the volumetric device was more difficult to use, displayed considerably more artifacts, and was not more sensitive than a mercury-in-rubber strain gauge.
对男性性唤起的客观测量最常见的是监测阴茎大小的变化。虽然周长变化是最常使用的，但据报道体积变化更敏感，因此更有效。六名男性志愿者观看一部色情录像带，同时记录他们阴茎的周长和体积变化。这两种测量方法显著相关（r = 0.68），但体积测量装置更难使用，显示出更多的伪影，并且并不比橡胶应变片汞柱更敏感。
