Why and how a member gets erect from a “technical” point of view

Morning erection is a common phenomenon that affects no man. This is a very interesting physiological phenomenon that can tell us a lot about the sexual functioning of the body. But what are the reasons that cause this bodily reaction?

Reasons for the “stood up” member
First, it is necessary to understand the causes of male erection in general. Excitement of the penis is the result of a complex interaction between the nervous and endocrine systems, which have a joint effect on the blood vessels of the body. Simply put, when a man experiences sexual arousal, his brain sends chemical signals to the penis that correspond to the nerves that control blood flow.
One of the hormones responsible for the desired chemical reaction is the male hormone testosterone. Blood enters the cavity of the penis and causes swelling of the genital tissue in this volume. In more detail this process is as follows:
- There are cavities in the penis that cause erectile function, which cause erectile function, which in turn retain blood and allow for increased size. Under normal conditions, the arteries leading to them are only half open, keeping the penis in its normal relaxed shape. However, when excited, the brain triggers a hormonal response and the arteries open completely.
- As soon as the blood enters, it rushes to the corpus cavernosum, which, as is already known, can store large quantities of it inside itself.
- Feeling the sudden freedom, a large amount of blood begins to flow through the veins, and due to the fact that it does not have time to leave them, the veins contract.
- This causes blood to become trapped in the flexible, elastic tissue of the penis.
- Then the latter swells, which leads to a significant increase in its volume.
- However, as soon as the man”s brain stops receiving signals of sexual arousal, the arteries return to their natural state and the erection goes away.
Despite the fact that, in principle, the initiator of this process is the brain, an erection can occur without its participation. In this case we are talking about an uncontrolled reflex that is initiated in the spinal cord.

And this partly explains why some men can experience erections even with spinal cord damage or complete sexual liberation.
Why does my penis get hard in the morning?
Knowing that the mechanisms that cause penis arousal are generally at work, it is much easier to understand why the morning penis is encouraged to be fully prepared for battle.

Often people have complexes due to failures in their intimate life. If they cannot satisfy their lover, they feel inferior. A.
It has been scientifically proven that morning, or more precisely, night, erections occur during the REM phase (stands for the “rapid eye movement” phase). This is a period during which the brain is characterized by increased activity. As a result, the areas of the brain responsible for parasympathetic and sympathetic stimulation come into play.

First, the parasympathetic endings are activated, which causes the body to relax and the digestion process occurs. Then, immediately, the sympathetic nerves are activated — they cause a direct response, usually called “boom-boom-go”. As a result, the brain jumps from one state to another, and the nervous system immediately reacts to this, causing an erection.
All these processes occur on an unconscious level, the person is asleep and does not even know about it. Such reactions are characteristic mainly of the rapid stages of sleep, but it is interesting that an erection can also occur in the stage of deep sleep, where the brain does not show such pronounced activity, especially in older people. Unfortunately, scientists do not yet have an answer to the question of whether this is happening.
The rapid stage of sleep is also characterized by the fact that dreams at this moment are very superficial, and the body is definitely awake during this period. For this reason, many men often wake up with an erect penis.

How often this happens also depends on the level of testosterone in the body. Usually this figure increases significantly in the morning. It has been proven that testosterone levels do not have a significant effect on erections caused by immediate sexual fantasies.
Interestingly, the number of nighttime erections is never limited. Since a person goes through several stages of REM sleep at night, a man can experience up to five erections in one night, each of which lasts on average from 20 to 30 minutes, but it all depends on the quality of sleep — if a man sleeps poorly, he should not be afraid of waking up every day with morning excitement.
And of course, with age, not only the number of erections decreases, but also their duration. However, this does not mean that after a certain age, erectile function in men completely ceases. Many of them continue to wake up in the morning with an erect penis even after many years. In addition, men taking drugs to increase potency, such as Viagra, are more susceptible to morning erections.

For what purpose is this happening?
If the reason for morning erection is more or less clear, then for many it remains a mystery to what purpose the body reacts.
One possible reason could be that morning erections are just a way of telling a man that his bladder is full. This conclusion can be made due to the fact that the erection in most cases weakens even after morning rest.
However, a more plausible theory seems to be that the feeling of a full bladder simply affects the nerves connected to the spinal cord.
What if there is no morning erection?
Lack of penile erection after waking up can be a fair cause for concern, as it often indicates the presence of erectile dysfunction. There may be several reasons for the lack of morning arousal:
