Age is one of the basic conditions for the development of prostate enlargement. 40 years old is an important turning point for men. The first thing you need to do is to get a good idea of what you are getting into. The actual “yin and yang should be like the great theory” said: “year forty, and yin gas since half carry on, living decay carry on.” Here the “Yin” refers to the kidney, the kidney is the root of the Qi. It means that after 40 years old, the functions of the body’s tissues and organs begin to decline, and endocrine disorders (including sex hormones) also begin in this period. The actual fact is that, after 40 years of age, there is no significant change in the proportion of smooth muscle and alveolar components in the prostate gland, but the epithelial and mesenchymal components are more affected by age, and as age continues to increase, the epithelial content decreases, while the mesenchymal component increases, and the rate of proliferation of mesenchymal cells is significantly higher than that of epithelial proliferation. After the age of 40, the prostate tissue mesenchymal cells are more active than the epithelial tissue, and in the event of prostate hyperplasia, the main manifestation is the proliferation of mesenchymal cells. The actual fact is that you can find a lot of people who are not able to get a good deal on a lot of things.
