Prostatic fluid discharge during erection

During sexual intercourse, when men are stimulated, their penises will become erect, and after the erection, some fluid will flow out, which is prostatic fluid, or the secretion of the prostate. The amount of prostatic fluid secreted every day is within a normal range. If it is not within this range, it means that there are some problems with the male prostate, and it is necessary to go to the hospital for examination in time, and then treat the symptoms according to the reasons found!

1. What is prostatic fluid?

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 0.5~2 ml. It is an important component of semen and one of the seminal plasma components in semen, accounting for about 1/10~1/3 of the amount of 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.

2. Physiological functions of prostatic fluid

1. Promote the formation of fertilized eggs:

Prostatic fluid contains protease and fibrinolytic enzymes, which can help sperm pass through multiple barriers - the mucus barrier in the cervix and the zona pellucida of the egg cell, allowing sperm and egg cells to combine smoothly.

2. Stimulate sperm vitality:

Prostatic fluid contains a special ingredient that enables sperm to obtain nutrients from semen and stimulate sperm vitality.

3. Promote the liquefaction of semen:

Chymotrypsin in prostatic fluid can promote the liquefaction of semen.

4. Improve the survival rate of sperm:

Prostatic fluid is slightly alkaline, which can neutralize the acidic secretions in the female vagina, reduce the erosion of acidic substances on sperm, and improve the survival rate of sperm.

5. Maintain the hygiene of the reproductive and urinary systems:

The prostate is located in front of the bladder and below the rectum, surrounding the urethra. The zinc ions in the prostatic fluid have bactericidal effects, allowing the prostate to play a role in resisting external pathogens, thereby helping to maintain the health of the reproductive and urinary systems.

6. Improve the quality of sex life:

The prostate is filled with a large number of nerve networks and nerve endings, so it is a sexually sensitive area that can stimulate sexual impulses and sexual excitement, thus contributing to a harmonious sexual life.
