目的：有必要对性功能正常的男性进行射精潜伏期和阴茎敏感性的客观和有效的测量。我们确定了1）正常男性在实验室与在家自慰和性交时ELT的正常范围和可重复性，2）由2个振动仪测量的6个阴茎表面区域上阴茎敏感性的阈值和可重复性，3）阴茎敏感性是否与射精潜伏时间相关。材料和方法：共有58名20至40岁的健康志愿者在3个过程中提供射精潜伏期时间，并使用生物感觉计和SMV-5振动计进行评估（Suzuki-Matsuoka，Teknologue，Tokyo，Japan）对6个阴茎表面区域进行了研究。射精潜伏期在性交时最长（中位数8.25分钟，范围1.32至18.31），实验室较低（中位数7.22，范围1.37至18.79），手淫期间最低（中位数4.89，范围1.08至14.19）。3个ELT评分在受试者中具有高度的可重复性（ICC 0.88至0.93）。受试者之间的差异很大。6个阴茎表面区域的振动触觉阈值也相似，并且对于2个振动计具有高度可重复性（ICC 0.81至0.96）。然而，阴茎敏感性与ELT之间没有相关性（R-2小于8%）。结论：实验室中的ELT低于性交时，高于手淫时。振动计产生可靠和可重复的阴茎振动触觉阈值的结果。然而，在性功能正常的男性中，阴茎敏感性测量与ELT无关。
Purpose: There is a need for objective and validated measurements of ejaculation latency time and penile sensitivity in men with normal sexual function. We determined 1) the normal range and repeatability of ELT in a laboratory vs at home masturbation and intercourse in normal men, 2) the threshold and repeatability of penile sensitivity on 6 penile surface areas measured by 2 vibrometers and 3) whether penile sensitivity correlates with ejaculation latency time.Materials and Methods: A total of 58 healthy volunteers between 20 and 40 years old provided ejaculation latency times during 3 procedures and were evaluated with a biothesiometer and SMV-5 vibrometer (Suzuki-Matsuoka, Teknologue, Tokyo, Japan) on 6 penile surface areas.Results: Ejaculation latency time was highest during intercourse (median 8.25 minutes, range 1.32 to 18.31), lower in the laboratory (median 7.22, range 1.37 to 18.79) and lowest during masturbation (median 4.89, range 1.08 to 14.19). The 3 ELT scores Were highly reproducible within subjects (ICC 0.88 to 0.93). There was high variability among subjects. Vibrotactile thresholds on 6 penile surface areas were also similar and highly repeatable for the 2 vibrometers (ICC 0.81 to 0.96). However, there was no correlation between penile sensitivity and ELT (R-2 less than 8%).Conclusions: ELT in the laboratory is lower than during intercourse and higher than during masturbation. Vibrometers produce reliable and repeatable penile vibrotactile threshold results. However, penile sensitivity measurements do not correlate with ELT in men with normal sexual function.
