Pathway 1: change bad lifestyle – make your vascular endothelial function stay young and energetic, and keep away from ED; Pathway 2: Traditional Chinese medicine – treating the disease is more than treating the person, treating the disease needs the root; Pathway 3: application of PDE5 inhibitors –The application of PDE5 inhibitors – large dose to treat the symptoms (on-demand treatment), small dose long-term service to treat the root cause (once a day, planned treatment); route 4: gene therapy, currently only a conceptual treatment. I comment: Pathway 1 is a prerequisite. My comment: Pathway 1 is the premise and treatment of peripheral work, laying the foundation; pathway 2 and pathway 3 in the identification of traditional Chinese medicine treatment combined with PDE5 inhibitors in small doses, standardized programmed treatment, the treatment is faster; pathway 2 and pathway 3 can also be applied alone.
