From the first two examples, it can be said that the overall health status is not necessarily directly related to erectile function, but it should definitely be related. These two middle-aged and elderly men are likely to have arteriosclerosis, leading to vascular erectile dysfunction. However, the degree of arteriosclerosis is not serious enough to affect other important physical functions such as cardiovascular system, so it is only manifested as erectile dysfunction. Sometimes, we can find some serious diseases that ED patients who claim to be disease-free don't know. For example, someone's ECG shows old myocardial infarction or fasting blood sugar as high as 23 (normal 3-6), indicating that ED may be the first symptom of other diseases and should not be taken lightly. Everyone's aging process is different. Generally speaking, "people get old before they get old", but these two first illustrate the problem of ED.
Of course, exercising and strengthening physical fitness will have positive significance for various functions of the body, but not all problems can be solved by panacea. If it really has such a great effect, there will be no need for hospitals and medical staff.
