Masturbation can lead to impotence
Refers to male impotence in sex, erectile or erection of the penis can not Kennedy or Kennedy in the near future and can not complete the normal sex life, or vaginal insertion of the penis can not have sex. Impotence, also known as "do not give Yang", is the most common male sexual dysfunction disorders. Occasionally one or two sexual failure, that is not suffering from impotence. Only a failure rate of sexual intercourse in more than 25% can be diagnosed with impotence.
According to statistical information, all the male impotence patients about sexual dysfunction 37% to 42%. Internal investigation showed that adult male about 10% of the occurrence of impotence. The incidence of impotence increases with age up. In the 50-year-old man, a lot of people will impotence, by 65 to 70 years old when the incidence of impotence peak. But it varies from person to person, absolutely not.
Penile erection is the nerve - the next penis intracavernous endocrine regulation of hemodynamic changes in the process. When sexual stimulation, non-adrenergic non-cholinergic neurons in the secretion of nitric oxide (NO), and other media nerve. Nitric oxide into the corpus cavernosum smooth muscle cells, the activation of guanylate cyclase, so that the GTP into the second messenger - cyclic guanosine monophosphate (cGMP). Intracellular cGMP concentrations increase, resulting in cavernous smooth muscle relaxation, cavernous sinus swelling of the penis, increasing blood flow. Corpus cavernosum volume increased around the penis albuginea passive extension of a long, so that the drainage of blood cavernous albuginea under pressure to extend lead narrow vein, venous resistance, hardness of the penis to increase too much, leading to penile erection. With the smooth muscle cells were cGMP phosphodiesterase V-type (PDE5) degradation, loss of its activity, as well as the resumption of sympathetic nervous after ejaculation, the penis into a weak state. As the selective PDE5 in the corpus cavernosum smooth muscle, the cGMP-specific PDE5 inhibitor therapy is the erectile dysfunction drug of choice for oral administration. Prostaglandin E1 corpus cavernosum injection for the treatment of erectile dysfunction, and its mechanism of action is by activating adenylyl cyclase so that the increase in the synthesis of cAMP, which can be induced corpus cavernosum smooth muscle relaxation, induced penile erection. In addition, adrenoceptor-mediated nerve media under the corpus cavernosum smooth muscle cell contraction, penile blood flow reduction in venous drainage and opening up, have a weak penis. Phentolamine is a adrenergic receptor antagonist, the corpus cavernosum injection therapy for the treatment of erectile dysfunction.
Most of the anti-impotence is a functional, a small number of organic. Its common reasons are the following:
1, the spirit of nerves: an early age, such as psychological trauma, or the wedding of a lack of knowledge, there is the psychological stress and anxiety, feelings of the husband and wife or not, and that is not harmonious family relations; or bad habits such as excessive masturbation force, but rather a result Reduce the sensitivity of the penis, nervous, thinking of the burden, and so can lead to impotence; excessive physical or mental, and spiritual stimulation or bad, too, such as depression, grief, fear, and so on, or Ziqingzongyu, sex life, and so on can be caused by excessive cerebral cortex Disorders arising from impotence.
2, diseases of the nervous system: the hypothalamus - pituitary tumors or other parts of the tumor, localized brain damage, such as the limitations of epilepsy, encephalitis, brain hemorrhage, such as oppression, spinal cord injury, spinal cord tumor, chronic alcoholism, multiple sclerosis, pelvic Operation around the autonomic nervous system damage may occur, such as impotence.
3, endocrine diseases: diabetes, pituitary insufficiency, testicular injury or dysfunction, or hypothyroidism and hyperthyroidism, such as the lack of adrenal function can lead to impotence.
4, genital urinary tract disease: prostatitis, benign prostatic hyperplasia, epididymitis, varicocele, and so can often lead to impotence. Part of the middle-aged patients is due to prostatitis and impotence caused by benign prostatic hyperplasia;
5, the influence of drugs: a lot of clinical drugs on sexual function is a disincentive, such as reserpine, guanidine bromide, digoxin, stability, furosemide, and metoclopramide can cause impotence and so on.
6, chronic fatigue: fatigue is able to cause impotence, because of muscle fatigue or excessive use of the brain, depression, anxiety, tension, such as the heart caused by fatigue as a result of the interference to arouse sexual desire, including brain function to reduce the inhibition of interest , The cortex limbic system to reduce feelings of excitement hub, as well as the pituitary gonadotropin and the male hormone testosterone and reduce the lower-excited.
