Previous research indicates that penile sensitivity is typically lower in men with erectile dysfunction than in age-matched controls. On the assumption that sensitivity might be greater in men with short ejaculation latency (premature ejaculation), the present research investigated penile threshold (sensitivity) to vibrotactile stimulation in men with premature ejaculation, erectile dysfunction, or a combination of the two. Premature ejaculators showed thresholds commensurate with controls, while men with erectile dysfunction, or combined erectile dysfunction and premature ejaculation, showed significantly elevated thresholds. Although premature ejaculators did not show penile hypersensitivity, there was a significant correlation in this group between ejaculation latency and threshold. Overall, these findings argue against a primary role for penile sensitivity in ejaculation latency, and suggest that other somatic factors or cognitive factors may play the more critical role in premature ejaculation.
先前的研究表明，勃起功能障碍男性的阴茎敏感度通常低于年龄匹配的对照组。基于射精潜伏期短（早泄）的男性可能具有更高敏感度的假设，本研究调查了早泄、勃起功能障碍或两者兼具的男性对振动触觉刺激的阴茎阈值（敏感度）。早泄者的阈值与对照组相当，而勃起功能障碍者或同时患有勃起功能障碍和早泄的男性，其阈值显著升高。虽然早泄者未表现出阴茎超敏反应，但该组射精潜伏期与阈值之间存在显著相关性。总体而言，这些发现反对阴茎敏感度在射精潜伏期起主要作用的观点，并表明其他躯体因素或认知因素可能在早泄中起更关键的作用。
