目的：研究年轻、健康、体力旺盛的男性志愿者夜间阴茎勃起的可重复性、刚性评价标准及性交可能产生的影响。材料与方法：我们招募了12名年龄在21 ~ 24岁的男医科学生加入研究。纳入标准为无疾病病史、可获得性伴侣和正常勃起功能。所有受试者使用RigiScan*设备完成3次3夜的记录，记录之间至少间隔3天。在最后一晚的录音中，受试者被要求至少性交一次。对记录的分析主要集中在最佳勃起事件以及每小时标准化的刚性和肿胀活动单位。结果：受试者完成了36,3晚的记录。在总共108次治疗中，有18次发生在性交之后。我们分析了562例勃起发作。所有3晚的记录包括至少1次阴茎尖端僵硬超过60%，持续时间超过10分钟。性交对夜间阴茎肿胀和僵硬无显著影响。当刚性和肿胀活动单位值按小时归一化并表示为3晚会议的平均值时，记录的值具有可重复性。结论：至少连续2晚的记录是评估夜间阴茎肿胀和刚性记录的必要条件。夜间阴茎肿胀和强直，至少有1次勃起发作，阴茎尖端强直大于60%，持续时间为10分钟，可能与效力有关。每小时记录的平均刚性和膨胀活动单位值可作为测量整体勃起活动的客观参数。此外，性交似乎减少夜间阴茎膨胀和硬度测量，虽然没有统计学意义。我们预计，这些标准的应用夜间阴茎肿胀和刚性评价将提高诊断有效性的测试。未来的研究将确定这些标准对于老年男性的评估是否过于严格。
Purpose: We studied the reproducibility of nocturnal penile tumescence, rigidity evaluation criteria and the possible effects of sexual intercourse in young, healthy, potent male volunteers.Materials and Methods: We recruited 12 male medical students 21 to 24 years old into the study. A disorder-free medical history, availability of a sexual partner and normal erectile function were the inclusion criteria. All subjects completed 3 sessions of 3 nights of recording using the RigiScan* device with at least a 3-day interval between recordings. During the last S-night recording subjects were asked to have sexual intercourse at least once. Analysis of the recordings was focused on the best erectile event as well as on rigidity and tumescence activity units normalized per hour.Results: The subjects completed 36, 3-night recordings. Of the total of 108 sessions 18 occurred after sexual intercourse. We analyzed 562 erectile episodes. All 3-night recordings included at least 1 episode of rigidity at the penile tip greater than 60% and more than 10 minutes in duration. Sexual intercourse did not significantly affect nocturnal penile tumescence and rigidity. When rigidity and tumescence activity unit values were normalized by the hour and expressed as mean values of the 3-night sessions, documented values became reproducible.Conclusions: At least 2 consecutive nights of recording are necessary to evaluate nocturnal penile tumescence and rigidity recordings. Nocturnal penile tumescence and rigidity with at least 1 erectile episode of tip penile rigidity greater than 60% and 10 minutes in duration may be associated with potency. Mean rigidity and tumescence activity unit values per hour of a recording may be used as objective parameters to measure overall erectile activity. In addition, sexual intercourse seems to decrease nocturnal penile tumescence and rigidity measurements, although not statistically significant. We anticipate that application of these criteria for nocturnal penile tumescence and rigidity evaluation will improve the diagnostic validity of the test. Future research will determine whether these criteria are too strict for the evaluation of aging men.
