研究设计：基于网络的安全调查。目的：从男性脊髓损伤(SCI)患者中获取有关性功能的特定信息。背景：全球网络。方法：18岁或18岁以上的脊髓损伤患者获得密码进入安全网站，然后回答调查问题。结果：生殖器感觉的存在与在性刺激过程中感觉身体内性紧张的能力以及精神唤醒转化为生殖器作为身体感觉的能力呈正相关。在病变平面以上形成新的觉醒区域与在病变下方没有感觉或运动之间存在相反的关系。性生活中痉挛的发生与勃起能力呈正相关。大约60%的受试者尝试过某种类型的勃起增强方法。只有48%的人在伤后成功射精，最常用的方法是手刺激、性交和振动刺激。最常被引用的射精原因是为了愉悦和性交。只有不到一半的人报告说经历过创伤后的性高潮，这受创伤后的时间长短和保留骶骨的影响。结论：脊髓损伤不仅损害了男性的勃起功能和射精能力，而且还改变了性唤起，提示有神经可塑性。需要进行更多的研究，以包括性功能的所有方面。
Study design: Secure, web-based survey.Objectives: Elicit specific information about sexual function from men with spinal cord injuries (SCI).Setting: World-wide web.Methods: Individuals 18 years or older living with SCI obtained a pass-code to enter a secure website and then answered survey questions.Results: The presence of genital sensation was positively correlated with the ability to feel a build up of sexual tension in the body during sexual stimulation and in the feeling that mental arousal translates to the genitals as physical sensation. There was an inverse relationship between developing new areas of arousal above the level of lesion and not having sensation or movement below the lesion. A positive relationship existed between the occurrence of spasticity during sexual activity and erectile ability. Roughly 60% of the subjects had tried some type of erection enhancing method. Only 48% had successfully achieved ejaculation postinjury and the most commonly used methods were hand stimulation, sexual intercourse, and vibrostimulation. The most commonly cited reasons for trying to ejaculate were for pleasure and for sexual intimacy. Less than half reported having experienced orgasm postinjury and this was influenced by the length of time postinjury and sacral sparing.Conclusion: SCI not only impairs male erectile function and ejaculatory ability, but also alters sexual arousal in a manner suggestive of neuroplasticity. More research needs to be pursued in a manner encompassing all aspects of sexual function.
