Doctor's answer:

Actually, morning erections refer to the natural erections that occur in men between 4 and 7 a.m. in an unconscious state, without being influenced by scenarios, actions, or thoughts. It is a normal phenomenon. However, sometimes morning erections may disappear, and the reasons for this are as follows:
Emotion: Excessive sadness, anger, or depression can significantly reduce morning erections.
Medication: Medications such as antitumor drugs, antihypertensive drugs, hypoglycemic drugs, antacids, and sedatives can lower morning erections.
Disease: Many diseases can affect sexual function and morning erections, such as hypertension, cardiovascular diseases, diabetes, and lumbar disc herniation.
Fatigue: Overexertion and mental exhaustion can also impact morning erections.
Unhealthy lifestyle habits: Excessive smoking, drinking, and irregular sleep schedules can also affect morning erections.
