The improvements in imbalance of collagen synthesis with VED therapy under different negative pressures. (a) Sirius red staining was conducted to show the change in the ratios of collagen I/III. (b) Significant outcomes were found in all VED therapy groups compared to the BCNC group, although no obvious differences were found among different VED therapy groups (Student's t-test was used for each comparison, ^*P < 0.05, n = 6 per group; scale bars = 100 μm). VED: vacuum erection device; BCNC: bilateral cavernous nerve crush.
