“…3 Although the exact mechanism by which LI-SWT plays a regenerative role in ED has not been concretely defined, there is evidence that its effects are due to improved endothelial function, regeneration of nerve fibers, angiogenesis, and corporal tissue remodeling. 4,5 This is a result of shock waves producing microbubbles, which induce sheer stress that activates biological pathways that cause increased expression of growth factors. 4 There is an important distinction that must be made between shock waves and radial waves, which are both advertised for their use in ED.…”
