Age-related erectile dysfunction
The maximum strength of erection develops in men after puberty and then gradually decreases. In general, by the age of 40, 40% of men will face signs of age-related erectile dysfunction (EED), and an additional 10 years of life increases their proportion by 10%. A characteristic sign of foreign economic activity is insufficient development of the second stage of erection in the presence of the first. That is, sexual arousal consistently causes swelling of the penis, but the proper rigidity is achieved only for a short time or is not observed at all. To understand the cause of this problem, let us analyze the pathogenesis of foreign trade sequentially at different anatomical levels: organ, tissue and cellular.
At the organ level, it is found that the incoming blood is constantly discharged through the outflow veins due to insufficient compression of their lumen from the corpus cavernosum. The fact is that with age, the corpus cavernosum gradually loses its ability to stretch and, with an erection, does not reach a size sufficient to press the veins against the outer shell of the penis. Therefore, increasing blood flow even with the help of drugs does not always solve the problem.
At the tissue level, a decrease in the elasticity of the corpus cavernosum is due to fibrosis and an increase in the number of collagen fibers in its tissues. Similar changes are characteristic of other tissues and organs with a lack of blood supply against a background of high oxygen demand (for example, with myocardial infarction). But what kind of deficiency of blood supply and lack of oxygen can we talk about in the penis?
At the cellular level, we find that oxygen deficiency (hypoxia) is due to the physiology of the MMC. Above, I have already mentioned that under conditions of sexual rest, MMC are in good shape almost around the clock, which reduces blood flow and the availability of oxygen to the surrounding tissues. Moreover, performing the work, the MMCs increase their own consumption of the already deficient oxygen, causing even greater hypoxia in the tissues of the corpora cavernosa. Thus, the MMC literally saw the branch on which they sit – they themselves die from hypoxia and grab all the cells that are voracious to oxygen into the next world.
Without timely regeneration, the niches of dead SMCs and tissues of the corpus cavernosum are gradually occupied by more economical cells and collagen. These tissues do not need an abundance of oxygen, but they are unable to regulate blood flow and irreversibly reduce the elasticity of the corpus cavernosum, which is the basis for the development of VED.
After these lines, the smart reader will decide that the prevention of foreign economic activity can be provided with the help of hands, porn and Viagra. But things are not as simple as they seem.Поділитися цим:
