What do you think of acupuncture for a curved penis?

Don't do it. I'm a big proponent of acupuncture, and use it myself in my practice for many issues. However, it is totally useless for peyronie's disease, and is potentially harmful. I would run from any practitioner who tried to tell you it would be helpful.
Be cautious. Acupuncture can cure many abnormalities, but straightening a curved penis may be beyond what tiny needles can handle. It isn't magic.
