Abstract

OBJECTIVES

To investigate the longitudinal changes of sexual function of Japanese men.

METHODS

From 1992 to 1993, we carried out a cross-sectional community-based study on sexual function in Japanese men aged 40-79 years. After 15 years, a follow-up study was carried out to determine longitudinal changes of their sexual function. Of the 319 participants in the initial study, 135 participated again in the follow-up study. Sexual function was assessed using the same validated questionnaire in the two studies.

RESULTS

Erectile rigidity declined in men of each age decade at baseline (40s, 50s, 60s and 70s) of the initial study (P < 0.01, <0.01, <0.01 and <0.05). The frequency of sexual drive was significantly decreased in men aged in their 40s, 50s and 60s (P < 0.05, <0.01 and <0.01). Men aged in their 40s were dissatisfied with their decreased sexual function (P < 0.05). In contrast, men aged in their 70s were satisfied with their sexual life (P < 0.01).

CONCLUSIONS

Over a 15-year period, the sexual function of Japanese men declined in each age decade. However, the perception of this decline differed among different age group. Most elderly Japanese men did not worry about their impaired sexual function.

摘要

目的

调查日本男性性功能的纵向变化。

方法

1992年至1993年，我们对40 - 79岁的日本男性性功能开展了一项基于社区的横断面研究。15年后，进行了一项随访研究以确定他们性功能的纵向变化。在初始研究的319名参与者中，135人再次参与了随访研究。在两项研究中使用相同的经过验证的问卷对性功能进行评估。

结果

在初始研究的基线（40多岁、50多岁、60多岁和70多岁）时，每个年龄十年段男性的勃起硬度均有所下降（P < 0.01、<0.01、<0.01和<0.05）。40多岁、50多岁和60多岁男性的性欲频率显著降低（P < 0.05、<0.01和<0.01）。40多岁的男性对其性功能下降不满意（P < 0.05）。相比之下，70多岁的男性对其性生活感到满意（P < 0.01）。
