The actual sperm in the semen is the messenger of fertility. Chronic prostatitis generally does not affect the sperm generation in the testes and the sperm maturation process in the epididymis of the patient. So, a lesion in the prostate will undoubtedly have an effect on fertility. In some cases of male infertility, chronic prostatitis is a very important cause. Chronic prostatitis can affect the quality of seminal plasma components through the following aspects, which in turn affects the fertility of the patient. 1, changes in semen composition Semen should contain a certain amount of nutrients to feed the sperm and help sperm movement. The acidity in the seminal plasma will increase in chronic prostatitis, making the pH level drop and the seminal plasma acidic. When the pH level decreases to the minimum required PH value of 6.0-6.5 for sperm survival, the sperm will abort, which is not conducive to the normal reproductive process; due to the large number of white blood cells that can appear in the prostate fluid, the PH value of the prostate fluid will also increase significantly, and therefore change the pH level of the seminal fluid, which is also It is not conducive to the survival of sperm. When the prostate has chronic inflammation, the activity of a large number of liquefaction enzymes in the prostate fluid decreases or the secretion decreases, the coagulation factor increases relatively, as well as the semen may contain bacteria, a large number of white blood cells, and may even be interspersed with a large amount of pus, making it difficult to liquefy semen, and the viscosity of semen increases significantly, which is not conducive to the normal activity of sperm. 4, the density of the mirror and the volume of semen changes The volume of semen in healthy men is 2-6 ML per ejaculation, and because the volume occupied by sperm is minuscule, the volume of semen is basically equal to the amount of seminal plasma. Inflammation of the prostate is, the secretion of seminal plasma is mostly reduced, which is not conducive to the survival and activity of sperm; the amount of seminal plasma sometimes increases, which reduces the density of sperm and dilutes the sperm, which also affects the reproductive function.
