Holding urine and penis erection

We all know that men have morning erections. For a normal man, erections are natural. However, some men say that they also have penile erections when they hold their urine at night. First of all, we need to make it clear that holding urine is not good. We should excrete according to the body's requirements. Why do penile erections occur when holding urine?

To be precise, the main reason why men's penises are prone to erection when they hold their urine is that their bladders are highly full, which can easily cause pressure on the sexual nerves inside the prostate.

It is understood that there are a large number of sexual nerve tissues distributed inside the prostate gland. These sexual nerve tissues can transmit various sexual stimuli felt by themselves to the sympathetic nerves that control the erection of the penis, thereby achieving and maintaining normal erection of the penis.

At the same time, if we carefully observe the longitudinal cross-section of the male urogenital system, we can find that the top of the male prostate is close to the bladder and connected to the bladder neck.

When men hold their urine, their bladders are highly full. On the one hand, the pressure inside the bladder will continue to increase, creating downward pressure, causing the bladder neck to drop down. On the other hand, as the amount of urine continues to increase and the gravity of urine continues to increase, the bladder neck is squeezed downward and also tends to drop down.

The tendency of the bladder neck to drop down will directly press on the prostate connected to it, stimulating the sexual nerves inside the prostate, causing excitement of the sexual nerves inside the prostate, and then causing or promoting erection of the penis.

Holding urine for a long time can "help sexual performance", but the prostate cannot handle it

After talking about the relationship between holding urine and penile erection, I believe that some male friends with erectile dysfunction have already begun to be excited and hope to improve or solve their penile erection problems by holding urine.

It is undeniable that by holding urine, the erectile dysfunction of some male friends can indeed be improved to a certain extent. However, in the long run, it will inevitably cause certain damage to men's urinary and reproductive health, especially prostate health.

In fact, in addition to the sexual nerve tissue, there are also a large number of vascular tissues distributed inside the prostate gland. These vascular tissues dominate most of the metabolic activities of the prostate. Therefore, the basic daily nourishment and maintenance of the prostate depends on these vascular tissues.

Experts point out that long-term urine holding can cause pressure on the prostate, causing excitement of the sexual nerves inside the prostate, thereby causing or promoting penile erection. At the same time, it can also easily cause local blockage of vascular tissue inside the prostate, poor blood flow, and obstructed blood circulation.

The local closure of the internal vascular tissue under the prostate, the poor blood flow, and the obstructed blood circulation will inevitably affect the normal metabolism of the prostate, thereby causing the prostate to partially or completely lose its basic daily nourishment and maintenance, weakening the prostate's own disease resistance and immunity. Any slight external stimulation may lead to the occurrence of prostatitis and other related diseases.

When the lesions of the prostate develop to a certain extent, they will directly cause damage to the sexual nerve tissue inside the prostate, affecting the normal perception and conduction of sexual stimulation by the prostate, which can easily aggravate the erectile dysfunction of the penis, and eventually lead to the tragedy of "holding urine to 'help sex' but lead to 'no sex'".
