Does L-Arginine help treat erecile dysfunction?

I have had ED since I was 13 years. Doctors believe that in my mind, but I know for a fact that is not. Finally I found a doctor who believed me and put me in Levitra. Now I have 20 years of age. I've heard of the L-Arginine and helps to treat erectile dysfunction. I was wondering if anyone out there has had a success of this and so if there is some kind to get. Please help. Thanks. Also where I can get the Pycnogenol?
