Study of psychosocial factors affecting premature ejaculation from the perspective of personality traits: a large sample cross-sectional study from Anhui, China.

Background: Personality traits are the intrinsic factors of mental health, and may play a role in the pathogenesis of premature ejaculation (PE), but few studies have evaluated the association between personality traits and the 4 types of PE. Aim: We aim to investigate the personality traits associated with PE in 4 types of PE and their associations with PE. Methods: Between February 2024 and February 2025, we conducted a survey in Anhui, China, and enrolled 1708 males. Personality traits were independently assessed by the Myers-Briggs Type Indicator (MBTI). The index of PE was used to evaluate ejaculation control, sexual life satisfaction, and distress caused by PE. Outcomes: Energy-Introversion, Perceiving-Sensing, Judging-Feeling, and Orientation-Perception may influence men's sexual activity, and the Energy, Perceiving, and Orientation have different effects on the 4 types of PE. Results: The ISFP personality type is most common in those with PE. Among the 4 subtypes of PE, the Introversion-Intuition-Feeling-Perceiving (INFP) personality type is most common in those with Lifelong PE (LPE), the Extraversion-Sensing-Feeling-Judging (ESFJ) personality type is most common in those with Acquired PE (APE), the Introversion-Sensing-Feeling-Perceiving (ISFP) personality type is most common in those with Variable PE (VPE), and the Extraversion-Sensing-Feeling-Perceiving (ESFP) personality type is most common in those with Subjective PE (SPE). Clinical Implications: Personality trait factors may influence the pathogenesis of PE, and the use of the MBTI personality assessment provides a new perspective on how personality traits play a role in the onset of PE. Strengths & Limitations: It is necessary to conduct larger-scale, more rigorous community-based studies to further elucidate the role of personality traits in the development of PE. Conclusion: Men with traits of Introversion, Sensing, Feeling, and Perception tend to have high sensitivity, introspection, and a deep pursuit of idealized relationships.
