Flow diagram of the animal experiment and erectile responses of rats after treatment. (a) The process of the establishment of DMED rat model and treatment of the experimental animal. (b) CR-WPI supplementation improves the erectile function of DMED rats. The red lines denote electrical stimulation of the cavernous nerve for 60 s. (c) The ratio of maximum ICP to MAP derived from all eight groups () is presented as bar graphs, and the data are shown as . (d) The total ICP is obtained by calculating the area under curve, and the data are shown as . and indicate a significant difference compared with the DM group. ^## indicates a significant difference compared with the sham group.
