When does prostatic fluid appear?

Prostatic fluid is a part of semen, which is secreted every day. It mainly comes from the prostate. It is effective in reducing the acidity of the vagina and ensuring the activity of sperm. Moreover, prostatic fluid can liberate sperm and completely combine with the fertilized egg. Prostatic fluid can stimulate the activity of sperm, promote the survival rate of sperm and improve the quality of sex life, so everyone can understand the physiological function of the prostate.

Prostatic fluid is a component of semen, accounting for about 15%-30% of semen. The normal ejaculation volume is 2-6ml, with an average of 3ml, of which about 1ml is prostatic fluid. The nutrients in prostatic fluid provide nutrients for sperm. Prostatic fluid is weakly alkaline, which helps to reduce the acidity in the vagina. In addition, the semen just ejaculated by men is often in a viscous coagulated state. This is because a substance called coagulation factor in the fluid secreted by the seminal vesicle is at work, the purpose of which is to prevent semen from flowing out of the woman's vagina at will during sexual intercourse. At this time, the sperm in the semen are tied up and unable to move. How can they complete their reproductive mission? 15-20 minutes after the semen is ejaculated, a substance called liquefaction factor in the prostatic fluid, which is actually some enzyme substances such as hyaluronidase, comes out to rescue and thin the semen. The sperm is liberated and then swims hard to the deep of the female reproductive tract to complete the combination with the egg.

Physiological functions

1. Promote the formation of fertilized eggs: Prostatic fluid contains protease and fibrosis, 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 motility: Prostatic fluid contains a special ingredient that enables sperm to obtain nutrients from semen and stimulate sperm motility.

3. Promote the liquefaction of semen: Chymotrypsin in prostatic fluid can promote the liquefaction of semen.

4. Improve sperm survival rate: 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. Maintaining the health 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 a bactericidal effect, which enables the prostate to play a role in resisting external pathogens, thus 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 sex life.
