At present, there is no clear understanding of the formation mechanism of prostatitis, but generally with the following important factors: First, the prostate gland congestion, the prostate gland is located in the pelvic floor of the deep, there are abundant venous plexus, resulting in the prostate gland inside the speed of blood flow is relatively slow. And various factors caused by the prostate gland local congestion, will further slow down the blood flow rate inside the prostate so that the blood pooled in the prostate, in this case once the pathogenic microorganisms arrived in the prostate, it is easy to breed in this. The slow blood flow happens to make the prostate local temperature rise, further for the growth and reproduction of pathogenic microorganisms to provide an ideal place. The second thing is that many prostatitis is caused by various microorganisms that invade the prostate, and since the prostate has a glandular duct that is directly connected to the urinary tract, these microorganisms are mainly spread through the urinary tract. There are many other factors that contribute to the development of prostatitis, such as decreased body resistance, irregular prostate massage, injection of drugs into the prostate without strict sterilization, and psychological factors and many other factors.
