You could try shockwave therapy.
Shockwave therapy uses energy from acoustic waves to trigger a process called neovascularization in certain parts of the body. When neovascularization occurs, new blood vessels form. This helps improve blood flow to the region.
This type of therapy has been used to help heart patients, people with kidney stones, and those with fractures and joint inflammation. Recently, scientists have investigated low-intensity shockwave therapy to help men with erectile dysfunction (ED).
Blood flow is critical to a man’s erections. When a man is sexually stimulated, arteries widen so that his penis can fill with blood. The blood is what gives the penis the firmness needed for penetration. A man who has problems with blood flow to the penis may have weaker erections or may be unable to have erections at all.
To administer shockwave therapy, a clinician applies a probe to the penis, which is coated in a special gel. Different areas of the penis are usually targeted. Treatment sessions may last for fifteen to twenty minutes. Men usually don’t need anesthesia or experience pain, although they might have a tingling sensation in the treated area.
