Men are afraid of the occurrence of impotence, so when they occasionally cannot complete sexual intercourse normally, they say that they are suffering from impotence. In fact, this may be caused by some reasons and is not a disease. Although impotence is a disease that can It is divided into two types: functional impotence and impotence. However, no matter whether patients suffer from any type of disease, their symptoms in daily life are similar. The only difference is that the latter will be combined with organic diseases, so in order for everyone to be able to It takes a few days every day to achieve early detection and early treatment. Today we will summarize the symptoms of impotence in detail.

Several common types of impotence are introduced:

1. Nervous impotence

Nervous impotence means that the erection center and peripheral nerves of the penis are damaged due to various reasons, and the penis cannot achieve normal reflex erection. The erectile function of the penis is controlled by the cerebral cortex, subcortical center, and spinal nerves. The spinal nerves are located in the lumbosacral spinal cord. Brain lesions, tumors, cerebrovascular accidents, traumatic brain injuries and brain surgery. Brain lesions can affect the thalamus-pituitary function. Damage to the thalamus-pituitary function will cause hormone secretion disorders, and the secretion of prolactin and sex hormones will affect erectile function. If the nerves located in the lumbosacral segment are damaged and the nerve fibers that control the reflex erection of the penis are damaged, impotence will occur.

2. Endocrine impotence

Endocrine impotence refers to sexual dysfunction caused by hormone secretion disorders and imbalances. The regulation of human sex hormones is controlled and fed back by the thalamus-pituitary-gonadal axis system. The main hormones include thyroxine, epinephrine, sex hormones, prolactin, etc. According to some statistics, among all patients with impotence, impotence caused by endocrine causes accounts for about 10% to 35%. Clinically, it is mainly divided into two types: primary and secondary.

There are many types of endocrine impotence, such as impotence caused by damage to the parasympathetic nerves that control the perineum due to diabetes; impotence caused by abnormal regulation of the hypothalamic-pituitary-gonadal axis, reduced androgen release, and increased secretion of estrogen and prolactin. Primary gonadal insufficiency can cause impotence by reducing the level of free testosterone in the blood. Hypercortisolism can inhibit the secretion of gonadotropins and the secretion of testosterone by Leydig cells in the testicles, leading to impotence. Feminizing tumors can occur in the adrenal gland. Or testicular interstitial cells, which increase estrogen and testicular atrophy, leading to impotence; hyperthyroidism or hypothyroidism, impedes the production of testosterone and testosterone-binding globulin, leading to impotence.

3. Functional impotence and organic impotence

Impotence is divided into functional and organic types. This is mainly the classification method of impotence, which has very important guiding significance for the identification, diagnosis and treatment of impotence. As the name suggests, functional impotence is an erectile dysfunction caused by mental and nervous system dysfunction. It usually starts suddenly and often involves mental stimulation factors such as fear, depression, anxiety, fright, guilt, and tension. Organic impotence generally has a slow onset and is often characterized by gradual onset and progressive aggravation. It is mostly related to organic anatomy abnormalities of sexual organs and other organs, or certain drug poisoning, trauma, etc.

4. Pituitary impotence fistula

Pituitary impotence is an impotence caused by a lack of gonadotropin in men due to the complete or partial loss of the function of the anterior pituitary gland, resulting in endocrine insufficiency, which leads to a decrease in the secretion of all hormones and a decrease in the function of all target glands. Pituitary impotence is accompanied by testicular atrophy, secondary sexual characteristic degradation, reduced sperm production, and infertility. If pituitary hormone deficiency occurs in children and adolescents, growth and development may be stopped or puberty defects may occur. The human pituitary gland is regulated by the hypothalamus and regulates the activities of the anterior pituitary gland and the posterior pituitary gland through two different pathways. Neurohormones synthesized in the hypothalamus regulate the synthesis and secretion of six major peptide hormones in the anterior pituitary gland, and pituitary hormones in turn regulate peripheral endocrine glands, such as the thyroid, adrenal glands, and gonads. When the function of the anterior pituitary gland is completely or partially reduced, the symptoms and signs displayed depend on the underlying disease and the lack of certain specific pituitary hormones.

The vast majority of patients often cannot feel anything abnormal about themselves, but occasionally they may have sudden or severe attacks. The earliest deficiency is often gonadotropin, followed by growth hormone deficiency. When the thalamus is damaged, the secretion of all hormones is reduced, which will be accompanied by hypothyroidism, hypoadrenal function, hypotension, and lack of tolerance to stress and stimulation. Therefore, patients with pituitary impotence are hypopituitarism syndrome. one of the manifestations, rather than an independent disorder. Therefore, the treatment is also comprehensive, and treatment of the primary cause, such as pituitary tumor resection, is the main treatment measure. Only by removing the cause can impotence be treated.

5. Vascular impotence

The nutrition and erectile function of the penis rely on the penile arteries and veins. The relaxation of the smooth muscles of the corpus cavernosum of the penis causes the opening of the penile venous sinuses, creating conditions for penile erection. Any disease that affects the arterial and venous blood flow of the penis can cause impotence.

6. Iatrogenic fistula

Iatrogenic impotence refers to the patient's sexual dysfunction caused by poor language skills used by doctors during diagnosis and treatment of patients. It can also be caused by various influences and methods. In each case, the common cause was that doctors played a causative role in the patient's erectile difficulties. This may be due to careless words or failure to explain to the patient in advance, or it may be due to the patient misunderstanding the doctor's instructions and explanations, or due to some language from authority figures, or excessively detailed explanations. Sometimes impotence can occur during treatment for other conditions, such as infertility, heart disease, prostate disease requiring surgery, etc. Erection difficulties can also be caused by inappropriate sexual treatment. Whether it is due to previous sexual dysfunction or treatment for anejaculation or retrograde ejaculation, patients may develop impotence. In addition, when carrying out relevant sexual knowledge education, the patient may have a wrong understanding of some issues in sexual knowledge due to cultural level or deviation in understanding, which may also cause iatrogenic impotence.
