What is prostate fluid?

Prostatic fluid is a milky white alkaline liquid secreted by the male prostate. Its main components include zinc ions, acid phosphatase, proteins and various enzymes. It is an important component of semen. Its main functions are to lubricate the urethra, neutralize the acidic vaginal environment, provide sperm nutrition, and participate in semen liquefaction.

1. Ingredient characteristics:

Prostatic fluid contains high concentrations of zinc ions, which have antibacterial effects； Acid phosphatase reflects prostate function ； Fibrinolytic enzymes are involved in semen liquefaction. These special ingredients are essential for maintaining male reproductive health, and the zinc content is about 100 times that of plasma.

2. Physiological functions:

As 30% of semen, prostatic fluid can dilute sperm density, and its alkaline properties can neutralize the acidic vaginal environment and extend sperm survival time. It contains fructose and other substances that provide energy for sperm, and protease helps semen liquefy within 15-30 minutes after ejaculation.

3. Secretion mechanism:

The secretion of prostatic fluid is controlled by androgens, and is discharged through the contraction of the pelvic floor muscles during sexual excitement. The daily secretion amount is about 0.5-2ml, and the secretion increases when sexual activity is frequent. Its discharge pathway mixes with seminal vesicle fluid during ejaculation and is excreted through the external urethral orifice.

4. Abnormal performance:

Patients with prostatitis may have prostatic fluid turn yellow, increase in viscosity, or contain white blood cells. Chronic inflammation can cause zinc levels to drop, affecting sperm quality. If the prostatic fluid obtained by digital rectal examination has >10 white blood cells per high-power field, it may indicate inflammation.

5. Health correlation:

The quality of prostatic fluid is directly related to fertility, and zinc deficiency may cause a decrease in sperm motility. Regular prostate massage can help promote secretion, but overstimulation may induce congestive inflammation. Men over 50 years old should pay attention to prostatic fluid occult blood testing to rule out the risk of cancer.

Maintaining a regular sexual life will help the metabolism of prostate fluid. It is recommended to ejaculate moderately 2-3 times a week. Avoid cycling or sitting for long periods of time to reduce prostate congestion. Pay attention to supplementing lycopene and zinc in your diet, such as eating oysters, pumpkin seeds, etc. When frequent urination, perineal swelling and pain, or abnormal secretions occur, routine examination of prostatic fluid should be performed promptly. Drinking more water every day to dilute the urine concentration, and doing moderate Kegel exercises to enhance the function of the pelvic floor muscles. These measures can help maintain the normal secretion and physiological functions of prostatic fluid.
