To investigate the self-reported sexual function of Japanese men aged 40 to 79 years in a community-based study and compare the results to a similarly conducted study in Olmsted County, Minnesota.
Two hundred eighty-nine Japanese and 2115 American men from the community were queried about ability to have erections when stimulated, sexual drive, and satisfaction with sexual activity using a self-administered questionnaire.
Both Japanese and American men showed an age-related decline in erectile function, sexual libido, and sexual satisfaction. In particular, 71% of Japanese men aged 70 to 79 years reported having erections only a little of the time or less when sexually stimulated, and 80% perceived sexual drive once per month or less during the past month. Although more Japanese than American men reported erectile dysfunction and decreased libido, there were no striking differences in self-reported sexual satisfaction between the studies. However, cultural and perceptual differences could play a role in these results, despite attempts to ensure linguistic equivalency in the questionnaires.
Although erectile dysfunction and decreased libido were noted by a greater proportion of Japanese than American men, the self-reported degree of satisfaction was comparable between the studies. Perceptions of elderly male sexual function and its impact on health-related quality of life may differ among races, sites, and countries.
在一项基于社区的研究中调查40至79岁日本男性自我报告的性功能，并将结果与明尼苏达州奥尔姆斯特德县的一项类似研究进行比较。
使用一份自行填写的问卷，询问了来自社区的289名日本男性和2115名美国男性在受到刺激时勃起的能力、性欲以及对性活动的满意度。
日本男性和美国男性在勃起功能、性欲和性满意度方面均呈现出与年龄相关的下降。特别是，70至79岁的日本男性中有71%报告说在性刺激时只有很少时间或更少时间能勃起，并且80%的人在过去一个月中每月感觉到性欲一次或更少。尽管报告勃起功能障碍和性欲减退的日本男性比美国男性更多，但两项研究中自我报告的性满意度没有显著差异。然而，尽管在问卷中试图确保语言等效性，但文化和认知差异可能在这些结果中起作用。
尽管报告勃起功能障碍和性欲减退的日本男性比例高于美国男性，但两项研究中自我报告的满意度程度相当。不同种族、地区和国家对老年男性性功能及其对健康相关生活质量的影响的认知可能存在差异。
