Getting up in the morning without a morning erection is mostly normal. Because morning erection is affected by many factors, no morning erection can occur if the patient is older, has recently stayed up late, drank alcohol, or is under too much mental stress, which causes the body to lose energy. It can be reversed by improving lifestyle habits and regulating the diet structure. Some men who masturbate too much or have frequent sex will also experience no morning erection due to excessive sperm discharge. Other cases are seen with underlying diseases, such as diabetic neuropathy, cardiovascular disease, recent history of surgery, cold, trauma, and application of sedative drugs. Or abnormalities in sex hormone levels, such as adrenal tumors and intracranial pituitary tumors, can cause the absence of morning erections. Therefore, when men occasionally experience no morning erection, it is important to clarify whether there are any other accompanying symptoms. You can observe for a while, if the morning erection improves, you can not worry about it, it is affected by recent fatigue or psychological factors. If there is no improvement and there are uncomfortable symptoms, a systematic examination should be performed.
