背景　醫療技術的發展改變了婦女對身體的想像，形塑了不同的性魅力。性魅力是性學常使用的概念，然其內涵及定義在護理學上並未被深入探討。護理人員是提供婦女衛教諮詢主要的專業人員，有必要釐清性魅力概念的意涵，以便進行護理研究、發展護理知識。目的　以演化觀點的概念分析法針對「性魅力」概念的本土適用性進行探討。方法　採歸納法分析不同領域的學術文獻、報紙平面媒體、訪談與田野觀察資料，並交叉比對以產生典範案例。分析在時間的演變下，意義、使用和應用等三個面向的概念屬性。結果　提出性魅力概念所具備的五種概念屬性及其特質，包含　1.性聯想的心理動態　2.個人美學的感官經驗；3.身體自發的本能力量；4.展現自我的身體語言；5.受到社會文化的規範。結論／實務應用　從概念的演變，看見強調生物性、物化女體和刻板男女性別角色的性魅力已有其侷限性，建議探究科技與社會如何改變性魅力概念，及如何展現台灣婦女自我和自主性的經驗知識，做為未來護理研究和知識發展的方向。

Background: Medical technology has transformed the body image of women and altered perceptions of beauty and sexual attraction. While ＂sexual attraction＂ is a fundamental concept in sexology, the characteristics of this concept have not been studied in the field of nursing. Because nurses provide advice and health education for women, it is essential to clarify the concept of sexual attraction for the benefit of related nursing research and for the further development of nursing knowledge. Purpose: This study explores the concept of sexual attraction in a Taiwanese social context using concept analysis based on an evolutionary perspective. Methods: Inductive inquiry is used to compare and contrast articles from the academic literature, magazines, and newspapers, and data from participant observation and interviews are used to generate exemplars. The process by which the concept of sexual attraction has evolved over time is captured from three distinct aspects: significance, use, and application. Results: The definitional statement of sexual attraction includes the five dimensions of: 1. sexual-oriented psychological dynamics; 2. personal aesthetics and sensory experience; 3. instinct body forces; 4. body language of self; and 5. social and cultural norms. Conclusions/Implications for Practice: This study scrutinized the changes in attributes that emphasize the biological, objectified body, and stereotyped gender roles of women. Further directions for research and nursing knowledge development are suggested. Examples include identifying the changes in the concept of sexual attraction that result from technological advancement and further clarifying the experiential knowledge of sexual attraction that represents the selfhood and independence of women in Taiwan.
