When it is hard, there is a transparent liquid

Men may find that when their penis is hard, there is a transparent liquid. However, this is mostly a normal physiological reaction. The discharge of liquid is even a sign of preparation for sexual life and a form of self-protection. However, men should also pay attention to prostate problems and whether there is inflammation. If there is no inflammation, it is the prostate secreting liquid, which is also a normal physiological phenomenon.

1. What is the reason for transparent liquid when it is hard?

The human body's self-protection function, the brain thinks that it is time to have sexual intercourse after it becomes hard, and is worried that insufficient lubrication will scratch the penis skin, so it releases information to allow the body to secrete some prostatic fluid to play a lubricating role.

2. Composition of prostatic fluid

The prostate can continuously secrete a thin, white sexual fluid with a pH of 6.5. In the ejaculated semen, prostate secretion fluid accounts for 1/10 to 1/3 of the semen. It contains many ingredients, such as zinc, citrate, various enzymes, proteins, and fibroblast growth factor.

1. Zinc: The prostate contains high concentrations of zinc. In addition to the antimicrobial effect known to date, many other effects of zinc in prostatic fluid are still unclear.

2. Citrate: Citrate can maintain the osmotic pressure balance of semen and maintain an appropriate acidity and alkalinity. After citric acid combines with calcium ions, it can control the liquefaction process of semen after discharge and prevent prostate stones.

3. Spermine: The smell and crystallization of semen are due to the presence of this substance. Its function is still unclear, but current research has found that it can protect sperm from participating in DNA replication and protein synthesis, activate RNA polymerase in sperm, inhibit bacterial growth, and many other functions.

3. Causes of increased prostatic fluid

Excessive prostatic fluid may be closely related to repeated congestion of the prostate. Due to repeated congestion of the prostate tissue, the prostate gland ducts expand, causing the prostate gland to overflow from the urethra. This is a functional change of the prostate. Excessive prostatic fluid is a sign of chronic prostatitis. Therefore, if male friends have excessive prostatic fluid, they should go to the hospital for a check-up as soon as possible.
