Most of them are functional, and a few are organic.The common reasons are the following aspects:
1. Psychiatric and neurological factors: If sexual psychology was traumatized in an early age, or lack of sexual knowledge in newlyweds, nervousness and anxiety, or disagreement between husband and wife, family relationships are not harmonious;The sensitivity of the penis is reduced, mental tension, and excessive ideological burden can cause impotence; brain or physical excessive strength, or bad mental stimulation, such as excessive depression, sadness, fear, etc., or indulgence, excessive sexual life, etc.Functional disorders appear impotence.
2. Neurological lesion: Hulkin-pituitary tumor or other parts of tumor, local damage to the brain, such as limited epilepsy, encephalitis, cerebral hemorrhage compression, etc., spinal cord injury, spinal cord tumor, chronic alcoholism, multiple sclerosis, pelvic cavity cavitySurgical injury can occur impotence.
3. Endocrine lesions: such as diabetes, incomplete pituitary function, testicular damage or low function, or hyperthyroidism in thyroid dysfunction, insufficient adrenal function can cause impotence.
4. Urinary genital organ lesions: such as, prostate hyperplasia, epididymitis, and varicocele, etc. can often lead to impotence.Some middle -aged and elderly patients are impotence caused by prostatitis and prostate hyperplasia;
5. Drug impact: Many drugs clinically have a inhibitory effect on sexual function, such as Liusi Ping, Pyrine, Gaoxin, Stable, Fast Urine, and Stomach Rehabilitation, etc. can cause impotence.
6. Chronic fatigue: The reason why fatigue can cause impotence is because of excessive muscle fatigue or the arousal of heart fatigue caused by overly brain, depression, tension, etc.The excitement of the emotional center of the cortex edge system, as well as the reduction of the secretion of the motor gonad hormone and the testicular of the pituitary gland and the reduction of sexual excitement.
【Phase】
The cause of impotence is complicated, and the research of pathological mechanisms is gradually improving, and its exact pathogenesis is not yet clear.According to the cause of impotence, it can be divided into three categories: psychological, organic, and medical derivative.
1. Psychological (mental and mental nature): Psychological impotence accounts for about 85 ~ 90%of the total number of impotence, which is the most common sexually transmitted disease.The patient has no organic disease that causes sexual dysfunction, but the penis cannot be erected during sexual intercourse, but under some non -sexual activities, such as dreams or some sexual stimulating books, movies, and bladder urine, and bladder urineWhen it is full, the penis can be erected during masturbation.The mechanism of psychological impotence may be caused by a variety of mental and psychological factors that interfere with the cerebral center and cause the brain nerve center to not get enough excitement.There are many psychological factors that cause impotence and will be discussed in detail in the following content.
2. Organic quality: Although organic impotence only accounts for about 10 ~ 15%of the total number of impotence, its cause is more and the pathological is complicated.As the side.
① Urology deformity: Congenital penile bending, double penis, penile scrotum displacement, rear bladder, urethral cracks, congenital testicular lack or dysplasia, penile sponge fibrous scar formation, sperm varicocele, etc.Bending, cavernous dysfunction, etc. cannot be erected.
② Urban diseases: Past inflammatory inflammation of the urogenital is more common, such as orchitis, epididymitis, urethritis, cystitis, prostatitis, etc. Among them, patients with chronic prostatitis are most common.Urinary reproductive system surgery and certain damage, such as prostate hyperplasia, prostate dehumidaries and urethral breaks, penis, testicular damage, etc. can cause impotence.Patients with chronic renal failure are often impotence due to testicular atrophy and testosterone decline.
③ Endocrine disease: There are many people caused by impotence due to endocrine diseases. They are mainly found in diabetes, hypothalamus-pituitary abnormalities and primary gonad function.According to foreign reports, about 23%to 60%of male diabetes patients follow different degrees of impotence.Its mechanism is mainly related to autonomous nerve fiber lesions on the penis sponge, penile vascular stenosis, endocrine abnormalities and mental factors.
④ Neurological diseases: sequelae of stroke, craniocerebral injury, cerebral palsy, severe muscle weakness, advanced syphilis, spinal cord injury, paraplegia, multiple sclerosis, lumbar disc herniation, chronic alcohol poisoning, etc. can cause impotence.Increased intelligence, schizophrenia, neuropathy, depression, epilepsy, etc. can also occur.
⑤ Cardiovascular disease and drug effects can also cause impotence.Such as anti -hypertension drugs of nailopopico, Li blood, phenolzine, cyanocyani, stomach recovery, triple ring antidepressant and hormone preparations (estrogen, progesterone) all have this effect.
3. Medical origins: Patients have a clinical occurrence of impotence due to doctors.This may be due to the accidental or detailed explanation of the doctors' erectile disorders, or it may be caused by the patient's wrong understanding of the doctor's explanation and guidance.Some are impotence during the treatment of other diseases.In addition, patients' wrong understanding of sexual knowledge introduced by relevant books and magazines and certain misleading can also cause impotence.
