A, erectile dysfunction or vascular lesions people in a sitting position, the pelvic blood stagnation, blood circulation slowed, especially the perineum and prostate chronic congestion, stasis, easy to make the local metabolites accumulate, can send neurovascular dysfunction. The blockage of the prostate gland ducts, poor excretion of glandular fluid, leading to chronic prostatitis, is also promoting the occurrence of erectile dysfunction, affecting sexual function. Sexual dysfunction has now been treated as a disease, because life is better, people live longer and have higher requirements for quality of life. The five functions of physiology – eating, drinking, pulling and sleeping are the basic physiological requirements, which one is missing will be a big problem, sexual function is beyond the basic functions, modern medicine is also very concerned about the function. First of all, let’s understand the male organ. It can be understood as a reservoir, there are inlet pipes, there are drains, the inlet pipe is the artery, fill the water in, the valve can not be opened, first block the water, the pool can swell up, this is the basic reason for erection. The drainage system is a vein, under the regulation of the body’s certain mechanisms, to a certain time valve open, the water a release, a physiological cycle is completed. The original old saying that the young man is great, to the age of the old will not work, many people think that belongs to the physiological factors, the age of the old will not work, this is the natural trend, do not take it seriously. But then foreign research statistics, 70% of poor erectile function is vascular factors, vascular atherosclerosis, a study found that poor erection is even the cardiovascular system killer – the early warning of coronary heart disease, the clinical to cause sufficient concern. There are many factors affecting cardiovascular, high mental tension, hypertension, diabetes, etc. can cause erectile dysfunction. The appearance of vascular lesions, to draw attention to the need to seek early medical attention. I was asked most often about medication in the clinic, and patients, young and old, always ask, “Can I take this medication? Won’t I become dependent after taking it?” I usually ask in return: Do you take medication for high blood pressure? One day without medicine, two days without medicine can not? The high blood pressure medication is certainly to eat, but why when it comes to erectile dysfunction obviously function has been a problem, it has become a bad medicine, will avoid this thing? In fact, the treatment of erectile dysfunction and other diseases have gone through a long course of development, in the beginning when people want to get erectile dysfunction, everything has been done: burning incense and prayer, believe that what is missing to make up for (such as monkey testicles grinding powder to take), into the drug, the placement of prosthesis, and finally coincidentally in 1998 the revolutionary birth of PDE5 inhibitors oral Western medicine, drug mechanism is the human body after the sexual impulse The mechanism of the drug is that the human body produces a substance called nitric oxide after the sexual urge, nitric oxide can inhibit the receptor circulation of blood vessels, energy is maintained, the arteries are fully dilated, erection changes. This vascular effect still acts specifically on the sexual organs. In fact, PDE5 inhibitors were originally intended to treat cardiovascular disease, but it turns out that the effect on cardiovascular disease is not particularly good, but can improve erectile dysfunction. This is a typical case of modern medicine’s “misguided” approach.
