Hi CRSJETTJT, how are you and how is your father-in-law doing? How old is he now and how well he manages to do his daily activities of living without an attendant? There are many causes for erectile dysfunction and also various treatment options depending on the age and cause of erectile dysfunction. Some of the causes are " Damage to nerves, arteries, smooth muscles, and fibrous tissues, often as a result of disease, is the most common causes. Diseases such as diabetes, kidney disease, chronic alcoholism, multiple sclerosis, atherosclerosis, vascular disease, and neurologic disease also cause erectile dysfunction. Lifestyle choices that contribute to heart disease and vascular problems also raise the risk of erectile dysfunction.
