The group-differences of ALFF between patients with pED and HCs and the scatter plots of correlation analyses. Patients with pED demonstrated lower ALFF in left dlPFC than HCs (voxel-level p < 0.001 uncorrected, cluster-level p < 0.05 FWE corrected, cluster size > 20 voxels). ALFF value of the left dlPFC was positively correlated with IIEF-5 score and SEARQ score after adjusting age, BMI, and mean FD in pED group (p < 0.05, Bonferroni corrected, **). ALFF, amplitude of low-frequency fluctuations; pED, psychogenic erectile dysfunction; dlPFC, dorsolateral prefrontal cortex; IIEF-5, International Index of Erectile Function 5; SEARQ, Self-esteem and Relationship Questionnaire.
