I'm writing this in the coed section because it may benefit all who read this. I have just heard some compelling evidence that suggests that erectile dysfunction may be one of the first symptoms of significant heart disease. I can tell you, that looking back in my personal life, this makes sense. If you are experiencing ED, are overweight (eat lots of meat and processed food, and in America, who doesn't), you are running the risk of diabetes and heart disease. Since many of us are using the little blue pill, maybe we ought to be asking ourselves, should we be asking our primary care physicians about our hearts. Again, from experience and inside knowledge (I have a retired chief of cardiology in the family), if you do request a check up, ask for a stress test WITH CONTRAST (a nuclear dye given during the test). A plain stress test is not the gold standard of tests. The problem with asking for that test is that insurance companies tend to reject it unless you say that you have had some chest discomfort (i.e. pain). If you must, stretch the truth in order to control your own health care. Good luck!
Hope this helps somebody.
