Why do men have nocturnal emissions? Is nocturnal emission normal? What are the causes of nocturnal emission (wet dream)?

Nocturnal emission is a type of spermatorrhea. Infrequent spermatorrhea is a normal phenomenon, so infrequent nocturnal emission cannot be considered a disease. So what kind of nocturnal emission is a disease and what kind of nocturnal emission is normal?

Physiological nocturnal emission

Men generally experience nocturnal emissions after they reach puberty. In modern society, the normal age for first wet dreams ranges from eleven or twelve to fifteen or sixteen years old. Nocturnal emission is a sign of sexual maturity in men, also known as "overflowing semen". It is caused by excessive accumulation of semen, so it is also called spermatorrhea, which is a physiological phenomenon. Nocturnal emissions mostly occur during sleep and are a type of ejaculation without sexual activity. Statistics show that more than 80% of unmarried men have experienced nocturnal emission, usually 2 to 3 times a month. As long as the body and mind are healthy, it will not cause any adverse effects. However, you must be careful not to have any psychological burden.

Physiological nocturnal emission is more common in young and middle-aged people who are unmarried or separated after marriage. A healthy person who is in good health and full of energy, or easily excited, or tired and nervous. Generally, it occurs once every two weeks or longer, with large amounts of spermatorrhea and thick semen. During spermatorrhea, the penis has normal erectile function and is not accompanied by other symptoms. (Sleeping on your stomach, using a quilt that is too thick, too heavy, or too warm in winter, which can cause the external genitalia to be compressed, rubbed, or stimulated, or wearing tight clothes that can confine and squeeze the erect penis, can easily lead to an increase in the number of nocturnal emissions.)

Pathological spermatorrhea

Pathological spermatorrhea is more common in middle-aged and elderly people, or those with congenital physical deficiencies. People with dull complexion, tired body, heavy smoking, excessive drinking, overeating of fatty and sweet foods, puffy or weak body, frequent masturbation, excessive sexual intercourse, and unsatisfied sexual desires. The frequency of nocturnal emission is frequent, some occur at night, or ejaculate spontaneously when awake, the amount of semen is small and thin, the penis is not erect during nocturnal emission, or cannot be erected at all, and symptoms such as mental fatigue, soreness of the waist and knees, tinnitus, dizziness, and physical weakness appear after nocturnal emission.

It is mainly caused by the dysfunction of the cortical center and spinal cord center, as well as certain diseases of the reproductive system, which are described as follows:

A. Mental factors: Because the sexual desire is too strong and cannot be restrained, especially the sexual excitement caused by sexual thoughts before going to sleep, the central nervous system of sexual activity is stimulated for a long time, which can easily induce nocturnal emission. (Such as excessive focus on sex, extreme sensitivity to sexual stimulation, too close contact with the opposite sex, or watching pornographic books or watching sexually stimulating scenes in movies.

B. Physical factors: The functions of various organs are not sound enough, such as incomplete function of the cerebral cortex, loss of control over the lower sexual center, and increased excitability of the erection center and ejaculation center, which can also cause nocturnal emission. (After strenuous physical or mental work, the body becomes tired, sleep becomes deep, and subcortical central activity is enhanced, which can easily induce nocturnal emission.)

C. Local lesions: Local lesions of the sexual organs or urinary system, such as phimosis, prepuce, urethritis, prostatitis, seminal vesiculitis, epididymitis, etc. These lesions can stimulate the sexual organs and cause nocturnal emission.

Causes of nocturnal emission

1. Psychological factors: Due to the lack of sexual knowledge, excessive concentration on sexual issues, and easy acceptance of sexual stimulation, the cerebral cortex continues to be sexually excited, thus inducing nocturnal emission.

2. Influence of sexually stimulating environment: Sexually stimulating scenes in pornographic books or movies stimulate the brain and induce nocturnal emission.

3. Excessive fatigue: Excessive physical or mental labor makes the body tired, sleep deep, and the subcortical central activity is enhanced, resulting in nocturnal emission.

4. Inflammatory stimulation: Inflammation of the external genitalia and accessory glands, such as balanitis, prostatitis, seminal vesiculitis, epididymitis, etc., can cause nocturnal emission.

5. Physical factors: sleeping on your back with warm and heavy bedding that stimulates and compresses the external genitalia, or wearing tight clothes that restrain and squeeze the erect penis, which can induce nocturnal emission.

6. When the sperm is full, it will overflow: Men's testicles continuously produce sperm, and the seminal vesicles and prostate also continuously produce secretions. When a certain amount of semen is stored in the body, it is automatically discharged from the urethra.
