Okay, here it goes, and let me know if we should be posting to the franktalk site I've seen mentioned, but haven't visited (yet). Husband has been taking the quarter dose of the Viagra and will be taking his full 100 tonight. No success with the ED yet, although we're having fun. This idea occured to me last night. When I had back issues 10 yrs. ago, part of the therapy was ultrasound (if I remember correctly) to the effected area to promote oxygenated blood flow and heal the muscles, calm the nerves (not sure of the nerve part since I'm not a PT person). They used the gel beforehand that is used when conducting ultrasounds on women during pregnancy. Felt good but no idea what was happening deep below the surface, which supposedly is where the ultrasound was effective. Dr. Mulhall's site mentioned the pump isn't really a good therapy since it brings "old blood" (not oxygenated) into the penis. He stresses the importance of keeping a good oxygenated blood flow there, and quickly, after PCa treatment, explaining the treatment with injections etc. to prevent irreversible atrophy. Has anyone tried ultrasound treatment as therapy for ED? Is it possible for lay people to buy the machinery and give it a shot? If we're on to something here, we want patent rights!
