I'm only 29 and i have completely lost erections due to some unexplained vascular disease. is there any way to cure this?

ED: You need to work with your doctor and perhaps urologist to completely identify the anatomic and physiologic cause(s) of your problem. Depending on the exact nature of the problem would predict the likelihood of improvement or cure of the ed.

Impotence: See a urologist and a vascular surgeon. You could have diabetes or aortoiliac clogging or your blood vessels. Diet, exercise and do not smoke.
