Graph analysis of DTI-based connectome: decreased local efficiency of subcortical regions in PE patients with high sympathetic activity.

The results highlighted the abnormal topological properties of structural brain connectome in PE with high sympathetic activity. We also suggested that the clinical features of PE were related to the abnormality of several brain regions involved in the central control of ejaculation and emotion. This study provided new insights into the central neural mechanisms of PE, which might offer biological markers for understanding the physiopathology of PE.
