1, the harm of male continuous ejaculation
Experts remind: frequent sexual intercourse, unhealthy sexual life, beware of nephritis. There are many types of glomerulonephritis, which can be divided into primary glomerulonephritis and secondary glomerulonephritis according to the initial cause. According to time, it is divided into acute nephritis and chronic nephritis, also known as chronic glomerulonephritis.
Frequent sexual intercourse is the most common pathogenic factor of renal infection.
Why do women feel dull pain or discomfort in their private parts, and how to activate her "sexual interest" switch, the "sexual" happy ring for women between the ages of 25 and 45? After comparison, they found that excessive sexual life is directly related to kidney infection. For example, frequent sexual intercourse is the most common pathogenic factor of kidney infection.
It is reported that frequent sexual life may lead to kidney infection in women. Kidney infection is a very common disease, and most patients are women. In the past, people didn't know much about the reasons for their illness. Dr. Soros of a health research center in Seattle, USA, solved this problem through research. His research team selected 240 young women with kidney infection and 500 healthy women for a questionnaire survey. After comparison, they found that excessive sexual life is directly related to kidney infection. For example, frequent sexual intercourse is the most common pathogenic factor of kidney infection.
People who have sex more than three times a week are more likely to get kidney infections. Generally speaking, four to five times a week, or having sex for too long every time, is considered "excessive" Excessive sexual life causes bacteria to invade the urethra and even rise to the bladder, leading to urinary tract infections in most women.
Bad living habits are also prone to urinary tract infections.
In addition, other sexual habits, such as changing sexual partners frequently and using spermicidal contraceptives, are also prone to urinary tract infections.
There are many types of glomerulonephritis, which can be divided into primary glomerulonephritis and secondary glomerulonephritis according to the initial cause. According to time, it is divided into acute nephritis and chronic nephritis, also known as chronic glomerulonephritis. Acute nephritis, chronic nephritis, nephrotic syndrome and nephritis are primary nephritis; Purpura nephritis, lupus nephritis, diabetic nephropathy and hypertensive nephropathy are called secondary nephritis.
Among them, acute nephritis is an acute disease mainly caused by diffuse glomerular damage of both kidneys caused by allergic reaction after infection. The disease is characterized by acute onset, and a series of clinical manifestations such as hematuria, proteinuria, tubular urine, edema, oliguria and hypertension appear 1-3 weeks after infection.
Men should be careful not to ejaculate continuously.
In normal sexual intercourse, about 200-400 million sperm shoot at each other's bodies, which enhances the mobility of sperm and becomes an important manifestation of male reproductive health. However, scientists have found that if a man ejaculates four times in a row within six hours, one day later, there will be no sperm in the semen that the man ejaculates.
This is not a good thing for young people who need to have children. Men who lack sperm are prone to dehydration and collapse.
Sperm deficiency will stimulate the normal physiological function of male testis and even affect the production of normal sperm in the future; There are not enough high-quality sperm, only the prostate and other parts secrete a lot of body fluids, and men are prone to dehydration and collapse.
How to judge whether sexual life is excessive?
There is no exact standard to judge excessive sexual life. We can make a general judgment from the following aspects.
Excessive sexual life is mainly manifested in: haggard face, emaciation, mental fatigue, listlessness, top-heaviness, general weakness, shortness of breath, sweating profusely, insomnia, dreaminess and lack of food. When the above-mentioned "signals" appear, I have already told you that sexual life has made you "overloaded" and must be adjusted immediately.
In short, sexual intercourse should be properly controlled, which is also an important "way to preserve health" in life. Indulging in frequent sexual intercourse is harmful to work, study and health, and should be paid attention to.
2. The physiological process of male ejaculation.
The first stage: the moment when a man "feels that ejaculation is coming" is just the moment before the first stage of ejaculation physiology begins. It takes about 2 seconds after this feeling appears to really expel sperm. That is to say, it is likely that the expansion of urethral bulb and the accumulation of semen components in urethral prostate caused the perception of proprioceptors and the inevitable feeling of ejaculation.
The second stage: in the second stage of ejaculation (pushing semen from urethra and prostate to urethral orifice), men's subjective feelings are divided into two stages: the first stage is to feel the rhythmic repeated contraction of urethral sphincter. This feeling is from the beginning of the discharge process to the end of the discharge. The subjective feeling of this contraction is different. The first two or three contractions are very strong, then gradually slow down and weaken, and finally they are not shooting, but flowing out. The second stage is euphoric ejaculation. This subjective feeling of euphoria was very strong at first, and then it decreased obviously. The second euphoria includes the judgment of semen volume. The greater the amount of semen discharged, the stronger the euphoria. If we compare the feeling of the first ejaculation after a long period of abstinence with the feeling of the second ejaculation just after the refractory period after the regression period, we can see the difference between them. In the same one-time activity, if a man ejaculates twice or three times, he can realize that the first ejaculation can get more pleasure (partly because of the influence of semen volume). This kind of subjective understanding is just the opposite of that of women, who often think that the last orgasm is more satisfying and full of pleasure.
It should be emphasized that with the progress of ejaculation, the feeling of uterine contraction in the first stage and the feeling of semen in the second stage are integrated. The feeling of contraction is often dominant because it exists from the beginning and lasts until the second period.
The subjective process of two-phase feeling in the second stage of male orgasm can be directly compared with the subjective feeling of two-phase contraction and regular tremor in the second stage of female orgasm. Contrary to the fact that female orgasm experience will be disturbed by external psychological stimulation, once male orgasm is started and contracted, it can no longer be controlled and delayed, and only semen can be discharged. No amount of external stimulus can stop this process.
