Ninety gaze features were derived across six attentional metrics and five regions of interest. A two\u2010stage feature\u2010selection procedure identified a compact subset of discriminative features, which were used to train a classifier with cross\u2010validation. Standardized self\u2010report questionnaires assessing sexual function, sexual inhibition, anxiety, and depression were also administered.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Eight eye\u2010tracking features distinguished pED from controls with 94.8% accuracy under leave\u2010one\u2010out cross\u2010validation. Relative to controls, men with pED showed reduced initial and sustained attention to sexually salient regions and increased attention to neutral regions, consistent with attentional avoidance. Questionnaire scores revealed lower sexual arousal and higher sexual inhibition, anxiety, and depression in pED, with gaze features indicative of attentional avoidance correlating with reduced arousal and elevated affective symptoms.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion and Conclusion<\/jats:title>\n                    <jats:p>This is, to our knowledge, the first study to combine eye\u2010tracking and machine learning to investigate pED, providing direct behavioral evidence for attentional avoidance of sexual cues. These findings provide behavioral evidence of altered attentional processing in pED patients with the comorbid pattern and underscore the potential of integrating eye\u2010tracking with machine
