Some people say: "Hundreds of sexual intercourse do not ejaculate for health and prolong life." In fact, this statement lacks scientific basis.The reason why this wrong idea is caused by the influence of errors such as semen in ancient medical books than blood, a drop of semen equivalent to ten drops of blood, intercourse, and ejaculation.
Men's urethra has dual functions of urination and excretion.Inner end of the urethra, starting at the bladder sphincter of the bladder neck; the outer end of the urethra is terminated at the center of the glans of the penis, called the outer mouth of the urethra.When the bladder is filled, the cerebral cortex issues an "urination" command. Through the reflection of the spinal nerve of the sacral region, the bladder sphincter is relaxed and relaxed. With the help of abdominal pressure and internal pressure in the bladder, the urine is excreted from the urethra.
In addition to the bladder sphincter, at the junction of 1/3 and 1/3 of the urethra, that is, the urethra passes through the urine reproductive diaphragm, and there is a sphincter, called the intensive sphincter of the urethral membrane.This sphincter has nothing to do with urination and only play a role in ejaculation.
When men are excited, the sphincter in the urethral end and the intensive sphincter of the urethral membranes outside it are in a contraction state.In this way, a closed small space is formed between the two. Sperm that is creened by the smooth muscle nodular of the epididymis and the ureter, which is mixed with the secretion of the prostate and the bundle of the sachet.When the accumulated semen is increased to a certain amount, or the stimulation of the penis reaches sufficient strength, the orgasm of sexual desire occurs, and the urethral membrane sphinculates diastolic, and the accumulated semen is ejected through the urethral mouth.During ejaculation, because the bladder sphincter does not relax, the urine will not be discharged from the body with semen.
During sexual intercourse, not ejaculation refers to the sudden stop of sexual intercourse before the orgasm of sexual desire during sexual intercourse.
From the perspective of sexual physiology, interruptive sexual intercourse can make the congestion of the entire reproductive system and pelvic cavity not quickly retreat. The cerebral cortex and spinal cord suddenly are in a state of tension and cannot be calm.Good rest.
In terms of sexual psychology, interrupt sexual desires have not been satisfied.In addition, when the feeling of ejaculation appears, it will not endure, and a little semen will be discharged from the urethra, and most semen will flow back to the ureter. The next time you urinate, you will discharge with the urine.For women, interrupted sexual intercourse makes their sexual desire unsatisfactory, and in the long run, sexual disorders have occurred.
Broken sex can induce certain diseases, such as chronic congestion of women's pelvic cavity, causing low back pain, poor sleep, etc., causing men to induce, ejaculation, sterile, blood essence, and nocturnal emission.
Since sexual intercourse, it should follow it and do not violate the physiological laws. If you want to extend your life through interrupt sexual intercourse, it is impossible.
