【摘要】性自我概念是多維的，也是理解人們性行為的關鍵概念。然而，其不同維度與性功能障礙之間的病因、關係和因果方向尚未完全闡明。本研究對5665名50歲男性組成的基於人群的隊列進行了調查，這些男性完成了關於性自我概念（包括堅韌度、身體意象、性自尊和性壓力感知）和性功能障礙的問卷調查。採用多元線性回歸分析評估了這些關聯。結果顯示，勃起功能障礙（ED）、終身/獲得性早泄、主觀/可變性早泄和性慾低下（LL）與更負面的身體意象（p < 0.001）、更低的性自尊（p < 0.001）和更高的性壓力感知（p < 0.001）相關。 ED、終身/獲得性早泄和主觀/可變早泄均與堅韌度相關（p < 0.001），但未發現與LL的相關性。負面的性自我概念與中年男性的性功能障礙獨立相關，這表明性自我概念是性功能障礙生物心理社會概念中的一個重要因素。這種關係的因果方向需要在縱向研究中確定。

[Abstract] Sexual self-concept is multidimensional and a key construct in understanding people’s sexuality. The etiology as well as the relationship and causal direction between its different dimensions and sexual dysfunctions are not fully understood. A population-based cohort (N = 5665) of 50-year-old men completed questionnaires on dimensions of sexual self-concept (toughness, body image, sexual self-esteem, and perceived pressure with regard to sexuality) and sexual dysfunctions. Associations were assessed using multivariable linear regression analyses. Erectile dysfunction (ED), lifelong/acquired and subjective/variable premature ejaculation (PE), and low libido (LL) were associated with a more negative body image (p < 0.001), lower sexual self-esteem (p < 0.001), and higher perceived pressure with regard to sexuality (p < 0.001). ED, lifelong/acquired and subjective/variable PE were associated with toughness (p < 0.001), an association with LL could not be shown. A negative sexual self-concept was independently associated with sexual dysfunctions in middle-aged men highlighting that sexual self-concept represents a relevant factor in the biopsychosocial conception of sexual dysfunctions. The causal direction of this relationship needs to be determined in longitudinal studies.
