- Abstract: Low-intensity pulsed ultrasound (LIPUS) is a non-invasive sonodynamic therapy that has been approved by the U.S. Food and Drug Administration for clinical use. Clinical trials have demonstrated that LIPUS ameliorates mild-to-moderate erectile dysfunction without adverse events. Histological analysis of the corpus cavernosum suggests that the therapeutic benefits of LIPUS may be attributed to alleviation of fibrosis, enhanced neovascularization, and promotion of innervation. Further investigations have revealed that LIPUS facilitates cavernous tissue repair through non-thermal mechanisms, including a cavitation effect, acoustic streaming, mass transfer enhancement, and direct mechanical stimulation. Mechanobiological transduction triggers molecular signaling cascades within endogenous cavernous cells, thereby stimulating cell proliferation, angiogenesis, extracellular matrix remodeling, and stem cell differentiation. Although LIPUS has the potential to induce cavernous rehabilitation in the treatment of erectile dysfunction, further investigations are necessary to elucidate the mechanisms via which LIPUS regulates each type of cavernous cell to determine the optimal parameters for this innovative therapy.
