Why do normal and healthy men get erections after sleeping at night and waking up in the morning?

The penis of a normal man is usually in a relaxed state except that it will erect under sexual stimulation and some external stimuli. But sometimes the reflection of internal organs can also lead to penile erection. The most obvious thing is that there are often many penile erections before waking up in the morning, which leads to the increase of pressure in the bladder and stimulation, which can lead to the subconscious reflex erection of the penis, which is often said to make the urine "unable to hold back". This is a normal physiological phenomenon, which is medically called early morning erection. However, the intensity of this erection phenomenon varies greatly, and it has never reached the level peculiar to sexual intercourse. According to the research data of an American scholar, when men are 20-30 years old, the number of erections increases in the morning and gradually decreases after middle age. A German doctor also studied this physiological phenomenon. He found that during the illness, penile erection disappeared in the morning and reappeared in the morning when the body recovered. So he suggested that penile erection in the morning can be used as one of the reference indexes to observe men's energy and health. However, the exact mechanism of penis erection in the morning has not been clearly studied so far. In any case, it is certain that penile erection in the morning is a normal physiological reaction of men, and the changes caused by individual differences of men are not consistent every day. We must not judge the quality of male sexual function by this alone. It is true that doctors need to take this as a reference when differentiating and diagnosing sexual function changes, which is completely when defining pathological conditions, but a normal man should not blindly distinguish between good and bad. Some men, once the erection stops or relaxes in the morning, suspect that they have impotence, so they are worried. The more they worry about impotence, the less erectile phenomenon in the morning, and even weakness. This is a terrible vicious circle, because psychological anxiety will lead to physical imperfections; And physical problems induce further psychological anxiety, etc., which is becoming more and more serious. At this time, we must seek medical treatment quickly. Not only will you get an erection in the morning, but if you look closely, you will often get an erection when you sleep. During sleep, there will be intermittent rapid eye movement period, and penile erection often occurs at this time. Generally speaking, there will be three or five erections every night, and the average time for each erection is 15 minutes, but some can be as long as one hour. As long as the structure and function of nerves, blood vessels and corpus cavernosum are normal, this phenomenon will occur, which is also an important indicator of sexual function; During this period, the erection of penis is relatively unaffected by psychological factors, and it can actually show its original function. This physiological phenomenon provides an extremely important index for the research and treatment of sexual function. For patients with impotence, if they still have an erection when they get up in the morning, then this impotence may be caused by psychological factors, and the direction of diagnosis and treatment will be adjusted accordingly, so some complicated examinations can be omitted. This penile erection phenomenon is very important in the research, diagnosis and treatment of sexual medicine. In the early days, in order to do this research, patients had to lie in the laboratory to observe and sleep, and the brain, ocular alkali and penis were all connected to the test circuit. If you want to record the hardness of penis erection, the observer must observe it all night. Once an erection is found, the hardness is measured immediately. This method is inconvenient and has a big error. Through continuous progress, a great breakthrough has been made in the examination of penile erection at night. At present, the main body of the instrument used is about the size of a palm, which can be fixed on the thigh, and the head and bottom of the penis are covered with two leather rings. This quiet sleep can record the number of penile erections in one night, as well as the time and hardness of each erection. This kind of examination is very important for the differential diagnosis of physiological and psychological impotence. Some patients with impotence have done this kind of examination. As a result, the computer printed it out the next day and found it normal. There is no cure for impotence. Some people will have temporary impotence due to various factors. If this kind of problem happens to older patients, the parties will often doubt whether they are really dying, leading them to worry about whether they can do it this time before having sex. The result is that the more worried you are, the less you can get up; Psychology will feel that they are really dying, and they will also have a lot of fears. If it can be affirmed through this kind of inspection, then a lot of remedial costs can be saved. In the complete sexual function, erectile function accounts for a large part of physiological function. If there is erectile dysfunction, it will be more difficult in the future. If there are doubts in this regard, the examination of penile erection at night can provide a lot of diagnostic data and provide important reference for the future treatment direction. Normal men get erections during sleep, whether adults or children.
