Why do men wake up with an erection?

The penis of a man is very interesting. Sometimes it is very soft, sometimes it is very small, and sometimes it becomes very hard and thick. This is actually the result of the function of the corpus cavernosum of the penis. When the corpus cavernosum is filled with blood, the penis will become larger and thicker. On the contrary, it will become smaller and thinner. Some male friends find that their penis will be erect every morning. Why is this?

Morning erection is very important for men

Many men will inadvertently find that their penis is hard due to "holding" urine when they just wake up in the morning: sometimes the erection is obvious and relatively firm, and men who understand this situation cannot help but feel secretly happy, thinking that this is a manifestation of strong sexual ability; if one day they find that the morning erection has disappeared, they will become worried, thinking that this indicates that they are no longer capable.

In fact, not only can unconscious erections occur in the early morning, but also during a man's deep sleep. This kind of penile erection usually occurs during the intermittent rapid eye movement period, that is, the dreaming stage. At this time, the penile erection is usually not disturbed by psychological factors and can more realistically reflect the male's sexual function. Clinically, this erection hardness and softness provides an extremely important indicator for the study and treatment of sexual function.

Generally speaking, men have three to five erections every night, and each erection lasts an average of 15 minutes, but can last up to an hour. As long as the structure and function of the nerves, blood vessels and corpus cavernosum of the penis are normal, there will be an erection.

In clinical diagnosis of organic ED in men, a professional hardness meter is used to check the nighttime erection. The instrument is about the size of a palm and can be fixed on the thigh. There are two leather rings on the head and base of the penis. It can record the number of penis erections in one night and the duration and hardness of each erection. This examination is very important for the differential diagnosis of physiological and psychological ED. After some ED patients have undergone this examination, they will find that they actually do not have erectile dysfunction, and the ED problem will be cured without treatment.

A German doctor has also suggested that men's morning erections disappear during illness, but reappear after they recover.

However, it is not objective to observe the morning erection by yourself, and men should not diagnose whether they have ED based on this alone. Sometimes excessive fatigue or other physical problems may also lead to abnormal nocturnal erections. If you worry about this unnecessarily, you will fall into a vicious cycle of "the more you worry, the worse it is, and the worse it is, the more you worry", and you may even develop ED.
