The prostate, as the largest accessory gland of the male reproductive system, secretes prostatic fluid that constitutes 1/10 to 1/3 of the semen and has the role of protecting, enhancing sperm activity and lubricating the urethra. The normal prostatic fluid is a milky white plasma liquid, with a normal daily secretion of about 0.5 to 2.0 ml, containing a total lipid of 280 mg/dl, of which phospholipids account for 65%, while lecithin is the main one. The number of white cells per high magnification field under the microscope is within 10, and a full field of lecithin vesicles is normal. The prostate fluid of patients with prostatitis is slightly yellowish and turbid or contains flocculent material. Macrophages swallow a lot of lipids, which increases the number of leukocytes in the prostate fluid, and the diagnosis can be established with more than 10 per high power field. The results are often related to the amount and thickness of the prostate fluid, the presence of combined urethral infections or specimen contamination, etc. Therefore, the diagnosis of prostatitis using prostate fluid microscopy should be reviewed three times in a row to make the diagnosis more reliable. 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. 4. Red blood cells: There are no or very few red blood cells in normal prostate fluid, i.e. no more than 10 per high magnification field of view. In the case of prostatitis, there can be more than 15 per high magnification field of view. In the event that prostatitis occurs the white blood cells can greatly exceed 10, the checklist shows ++++ (each + represents 10 white blood cells). 6, sperm: If the prostate gland is massaged with pressure on the seminal vesicle gland, sperm can be detected in the prostate fluid. 7. Trichomonas and mycobacteria: Normally there are no trichomonas and mycobacteria in the prostate fluid. When there is trichomonas and mycobacteria infection can be detected in the prostate fluid.
