Some married men have normal penile erection during sexual intercourse with their wives; During a tryst with a lover, the erection of the penis is very unsatisfactory, and even impossible. Due to unknown reasons, many men with the above experience naturally attribute the causes to "kidney deficiency", "disease", "aging", and even "providence" and "retribution". In fact, the medical community has already provided a definition of the aforementioned phenomenon "external impotence".
Extramarital impotence refers to the ability of married men to achieve normal erections during marital sexual activity; During extramarital sexual activity, the penis cannot achieve a normal erection, or even cannot achieve an erection at all.
It is understood that extramarital impotence is mainly related to negative psychological and psychological factors such as nervousness, shyness, worry, and fear of the parties involved, such as "kidney deficiency", "disease", "aging", "providence", and "retribution", and is not closely related.
Experts say that penile erection is mainly controlled by the sympathetic nervous system (some vegetative nerves) in the human body. Adverse psychological and psychological factors such as nervousness, shyness, worry, and fear can easily cause sympathetic nervous system disorders in the human body, thereby affecting the normal erection of the penis, and even completely unable to achieve an erection. However, there are exceptions.
A large number of ganglia are distributed within the prostate gland. On the one hand, these ganglia have sensory and conduction functions for sexual stimuli; On the other hand, these ganglia are connected to the sympathetic nervous system that controls penile erection through nerve branches and nerve endings.
Men are sexually stimulated by the prostate ganglion and transmit it to the sympathetic nervous system of the human body through nerve branches and nerve endings, thereby achieving a normal erection of the penis. When the prostate gland undergoes pathological changes, the prostate ganglia are damaged, making it impossible to achieve normal sensation and transmission of sexual stimulation. The sympathetic nervous system in the human body cannot obtain sufficient sexual stimulation through the prostate ganglia, thereby affecting the normal erection of the penis.
Therefore, experts remind that patients with "extramarital impotence" who have been out for a long time and have extremely limited sexual life should undergo a prostate examination to determine if there is any prostate disease.
