Purpose: The purpose of this study was to analyze the relation between sex perception, sexual life satisfaction, and life satisfaction of the elderly. Methods: The respondents were 227 elders aged over 65. Data were collected from February 10 to December 15, 2007 by interviews and questionnaires. Results: Of the respondents, 18.8% still had sex life and 25.5% wanted to have a date. The main reason to have a date was to relieve loneliness, and the percentage of those who wanted a date was 58.3. The perception level of sex life was 2.27 (men: 2.51, women: 2.14), the satisfaction level of sex life was 2.74 (men: 2.89, women: 2.64), and the level of life satisfaction was 2.98 (men: 3.10, women: 2.92). There was a positive correlation between the perception level of sex life and the satisfaction level of sex life; a positive correlation between the satisfaction level of sex life and the level of life satisfaction; and no correlation between the perception level of sex life and the level of life satisfaction. Conclusion: This study provides a base supporting the usefulness of various nursing intervention programs to enhance the quality of life through making elderly people have a positive perception of sex life.
