Sexual desire is an extremely complex nerve reflex activity, and all kinds of sexual stimuli can cause sexual impulses. For example, talking about a love affair, hugging and kissing with lovers, reading romance novels, yearning for sexual life, and even the beauty of the opposite sex or enthusiasm from the opposite sex can all be used as sexual stimulation, which can reflexively arouse the excitement of the cerebral cortex sexual center through vision, hearing and contact with the senses. The cerebral cortex transmits excitement to the spinal cord. On the one hand, it excites the spinal cord center that controls genital erection and causes penile erection; On the other hand, it increases the secretion of glands and ducts in the reproductive system, and a large number of secretions (mainly prostatic fluid, seminal vesicle fluid, etc. ) accumulated in seminal vesicle, vas deferens, epididymis and its urethra. At this point, if sexual intercourse occurs, through ejaculation, these secretions constitute semen and are excreted together with sperm. But if there is no sexual intercourse, these secretions will not be ejected, but will be in a state of "sperm is too full to overflow". In this way, the prostate, vas deferens and epididymis will passively expand, stimulate the nerves of these organs, and cause pain reflexively. At first, it only happened in the testicles. If sexual excitement does not converge, the pain will spread upward along the vas deferens, causing slight abdominal pain and even low back pain. In severe cases, sometimes you can't stand up straight, so you can only bend over to help your abdomen.
Testicular pain caused by sexual stimulation is a physiological phenomenon, not a disease. After the sexual stimulation stops, the secretion is gradually absorbed and overflows from the urethra, and the pain will gradually subside without leaving any sequelae. Therefore, there is no need for treatment in this situation. The key is to avoid sexual stimulation or control sexual excitement immediately.
