What happens if a man has discharge on his underwear?

It is actually normal for men to have secretions on their underwear. Especially for some younger men, some prostatic fluid will be secreted. Because the prostate is located at the urethral opening, it is normal for some residue to remain on the underwear. However, if you find that there are other reasons for the secretions on the underwear, then it is recommended that you go to the hospital for examination to avoid other diseases.

Prostatic fluid is the secretion of the prostate. The secretion of prostatic fluid is controlled by male hormones, and the daily secretion volume is about 0.5 to 2 ml. It is an important component of semen and one of the seminal plasma components in semen, accounting for about 1/10 to 1/3 of the ejaculated semen. 1/6 is about 0.5 ml. In the ejaculation sequence, prostatic fluid is one of the leading components of semen. The protein content in prostatic fluid is very low, mainly containing high concentrations of zinc ions, acid phosphatase, protease, fibrosis, spermine, aliphatic polypeptides, etc. Among them, protease and fibrosis have the effect of promoting semen liquefaction. The detection of acid phosphatase and citric acid can help judge the function of the prostate and whether there is cancer.

When the inflammation is severe, the substance may become thicker, yellower or reddish, or contain flocculent matter and sticky. The following components can be seen under a microscope:

1. Lecithin bodies are evenly distributed in prostatic fluid. They are spherical bodies, large, highly refractive, and numerous. Normal prostatic fluid contains 280 mg/d1 of total lipids, of which 65% are phospholipids, and lecithin is the main component. Lecithin bodies are almost everywhere in the field of vision. When the prostate is inflamed, macrophages phagocytize a large amount of lipids, so the number of lecithin bodies decreases significantly. Therefore, the number of lecithin bodies reflects the severity of prostatitis to a certain extent. As the condition stabilizes and improves after treatment, the number of lecithin bodies may also increase.

2. Blood cells include white blood cells and red blood cells. Under normal circumstances, red blood cells are occasionally seen, and only appear during inflammation. Excessive massage can cause an increase in the number of red blood cells, and even visible bleeding. Normal prostatic fluid contains scattered white blood cells, no more than 10 per high-power field of view, and they are dispersed, not in piles or strings. During inflammation, due to the uncontrolled drainage of the excretory duct, pus cells or white blood cells may be seen in piles. If more than 10-15 white blood cells are observed per high-power field of view under a microscope, bacterial prostatitis can be diagnosed.

3. Starch granules, stones or sperm can also be seen in prostatic fluid, but they are not of great significance in the diagnosis of prostatic diseases, so they are generally not introduced. The biochemical components of prostatic fluid are very rich, including pH, zinc, acid phosphatase, citrate and leucine aminopeptidase, etc., which are of significance in the diagnosis of prostatic diseases. The content of zinc and various enzymes will decrease when inflammation occurs, but it is rarely used in clinical practice.

4. Protein The content of protein in prostatic fluid is very small, and it mainly contains high concentrations of zinc ions, acid phosphatase, protease, fibrosis, spermine, aliphatic polypeptides, etc. Among them, protease and fibrosis have the effect of promoting semen liquefaction, and the detection of acid phosphatase and citric acid can help judge the function of the prostate and whether there is cancer.

Prostatic fluid and semen are different, but the two are closely related. Prostatic fluid is a component of semen, mainly secreted by the prostate, while semen contains secretions from multiple glands. Semen is a mixture of sperm and seminal plasma. Sperm is a large number of living cells produced in the seminiferous tubules of the testicles. Seminal plasma is composed of testicular fluid, epitesticular fluid, vas deferens peritoneal fluid, accessory gland secretions and urethral gland fluid, including prostatic fluid. Prostatic fluid accounts for about 20% to 30% of seminal plasma, but the largest amount is the seminal vesicle secretion fluid, accounting for about 60% to 70% of seminal plasma, and the remaining components account for only 10%. Seminal plasma is a necessary medium for transporting sperm, and it also contains substances necessary to maintain sperm life and can stimulate sperm motility. Semen contains many substances, such as high concentrations of organic substances, inorganic ions and various enzymes. Among them, many enzymes related to semen coagulation or liquefaction come from prostatic fluid, such as aminopeptidase, fibroblastic protein lysing enzyme, arginine ester hydrolase, etc. In addition, citric acid is all secreted by the prostate, and its function is to maintain semen osmotic pressure and the activity of sperm hyaluronidase.
