Erectile dysfunction, also known as impotence in daily life, can be divided into endocrine impotence, iatrogenic impotence, neurological impotence, functional impotence and organic impotence, pituitary impotence and vascular impotence, with different symptoms. In the early stage, patients may have sexual hyperfunction, and in the later stage, sexual desire may decline or disappear, spermatorrhea or even infertility
1. Endocrine fistula
Endocrine impotence refers to sexual dysfunction caused by hormone secretion disorder and regulation imbalance. The regulation of human sexual hormones is caused by the thalamus - pituitary - the main hormones include thyroxine, epinephrine, sex hormones, prolactin, etc. Clinically, it is mainly divided into primary and secondary. There are many kinds of endocrine impotence, such as diabetes (diabetes: a group of metabolic diseases characterized by high blood sugar, the typical symptom is "more than three and less", that is, more drink and more urine, more eat and more thin.) impotence caused by impairment of perineal parasympathetic nerve; Abnormal regulation of hypothalamus-pituitary-gonadal axis, decreased androgen release, increased secretion of estrogen and prolactin, resulting in impotence, primary gonadal dysfunction, reduced free testosterone level in blood, resulting in impotence, increased cortisol, inhibition of gonadotropin secretion and testosterone secretion of testicular interstitial cells, and then impotence; Female tumors, which can occur in adrenal gland or testicular interstitial cells, increase estrogen and atrophy testicles, leading to impotence; Hyperthyroidism or decline of thyroid function will cause testosterone and testosterone binding globulin disorder and impotence.
2. Iatrogenic fistula
Iatrogenic impotence refers to the sexual dysfunction of patients due to poor language art in the process of diagnosis and treatment by doctors. In each case, the common reason is that the doctor plays a pathogenic role in the patient's erectile difficulty. This may be due to careless remarks or failure to explain to the patient in advance, or misunderstanding of the doctor's guidance and explanation, or due to some authoritative language, or too detailed explanation. Sometimes impotence may occur in the treatment of other diseases, such as infertility, heart disease, prostate disease requiring surgical treatment, etc.
3. Neurogenic impotence
Nervous impotence refers to that the penile erectile center and peripheral nervous system are damaged due to various reasons, and the penis can not have normal reflex erection. The erectile function of the penis is controlled by the cerebral cortex, subcortical center and spinal cord nervous system. The spinal cord nerve is located in the lumbosacral spinal cord segment. Brain injury, tumor, cerebrovascular accident, brain injury and brain surgery. Brain injury will affect the hypothalamus-thalamic pituitary function. Impaired pituitary function will lead to hormone secretion disorder, and prolactin and sex hormone secretion disorder will affect erectile function. If the nerve in the lumbosacral region is damaged, the nerve fibers that control the penis reflex erection will appear impotent.
