How to prevention from ED?
Impotence refers to during cannot erect, man or erection hardness is insufficient, or not lasting (namely easy fatigue soft), causes not intercourse.
In recent years due to the continuous improvement, inspection method for impotence etiology also had further understanding, is now proof impotence and the following several aspects about:
1, the implement qualitative lesions of sexual excitement is the cerebral cortex inhibition to strengthen, spinal cord erectile central excitability drops. The so-called functional reasons, not implement qualitative exist, can be a long-term or sex excessiveness, make neurological often in excessive excited state, eventually excessive and failure with excitement. Can also is a chronic disease, physical weakness or excessive fatigue, is caused by the physical or mental body except by weak or neurasthenia. Another reason is from the mental factors, such as fear, sexual intercourse environmental adverse, couple emotional apathy, or thought once spermatorrhea, masturbation and worry too much, or even for a sexual function lack of sexual knowledge produced or fear of her fear of the psychological factors. Blame
2, organic reason for the elderly, each organ system lesions, drug effects or surgery, such as the impotence caused by this kind of patient even in strong sexual stimulation situation all cannot erect penis, about 60%, are summed up and implement qualitative sex of impotence reasons are:
1) nervous disorders: such as spinal cord injury, spinal cord hengduan, spinal tumors, temporal lobe lesions, but because the conductivity excited for neurological disorders and cause impotence.
2) blood supply inadequate: atherosclerosis or other vascular diseases which can lead to blood supply shortage. Atherosclerosis, such as occur in the penis artery or dominate supply of blood vessels, yi ke makes nutrition patient happening impotence.
3) endocrine disorders: mainly diabetes, the hypothalamus gland anomalies and primary gonad dysfunction:
(1) diabetes accounted for about 50% more patient happening impotence, the crowd more normal age 2-5 times, if have peripheral and plant nerve lesions and vascular abnormalities aggravating impotence, more general with diabetes degree of impotency vascular and retinopathy degree is not uniform. The main factors happen impotence caused by diabetes, metabolic disorder neuropathy Diabetes causes caused obturator artery stenosis of blood flow to the penis is reduced, and diabetes cause metabolic disorder factors;
(2) the hypothalamus pituitary abnormality, accounts for about 7 to 19% of impotence patients pituitary tumor, mainly is around, other lesions are infiltrating or pituitary blood vessels). Promote impotency gonadal hormone release for promoting factors GnRH) to a reduction in the hormone (or follicle-stimulating hormone induces luteum production hormone (LH and FSH) reduce and prolactin increase;
(3) not all primary function, common with congenital and two Japanese b encephalitis Klinefelter syndrome, such as: the former congenital bilateral no inhibits the disease. If the latter sex mumps and inflammation, vascular disease, chemotherapy or radiation therapy, etc.;
(4) cortisol increase disease, bilateral adrenal cortical hyperplasia, adenoma, gland cancer or iatrogenic lead to increased cortisol, inhibits gonadotropin and leydig cell secrete testosterone and cause impotence;
(5) the hyperthyroidism, thyroid function about 56 percent of the hyperkinetic thyroid function, but mechanism can happen impotency is unclear;
6 hypothyroidism, this disease causes thyroid hormone secretion decline, testosterone and testosterone combining globulin reduce, prolactin increase. The cause is the whole impotence obstacles to the protein synthesis of fine fine tube testicular song degenerative diseases, and stroma cells reduce involved;
Adrenal insufficiency, is behaved with angular, malnutrition, so that the pituitary gland secretion LH and leydig cell secrete testosterone reduce involved; The tumor, and the tumor 7 May occur in adrenal or leydig cell, laboratory examination has estrogen, resulting in increased change development, testicular atrophy cause impotence.
3 and other organic disease
Including:
(1) drug effects, such as metformin b organism, reserpine, methyl dopamine, Ann palace progesterone, anticholinergic drugs, estrogen, etc.;
(2) all sorts of complications, such as the perineal resection, sympathetic resection, colorectal cancer, can affect vesssed erections anatomy and learn and cause impotence;
(3), such as lead and toxic substances (two block herbicides plants grow chemicals);
(4) trauma, such as testicular trauma neutered, pelvic fractures, penis trauma, etc.;
5 urinary system diseases, the penis scleroma disease, scrotal seeper, varicocele, packet stem, scrotal rubber is swollen, etc are likely to cause impotence.
