The difference between prostatic fluid and semen

Semen is also composed of prostatic fluid. Sometimes you may not know the difference between prostatic fluid and semen. Prostatic fluid is a component of the human urinary system and is secreted by the prostate, but semen is secreted by the testicles. Semen contains sperm and can combine with the egg to conceive life, but prostatic fluid does not have such a function. Although the two are different, semen also needs prostatic fluid to lubricate the vagina so that it can smoothly enter the uterus and meet the egg. Although we are not doctors, we can still learn about the two. Detailed explanation of the difference between prostatic fluid and semen.

1. The secretory organs of the two are different. Prostatic fluid is secreted by the prostate, while semen is a combination of fluids secreted by multiple glands. Prostatic fluid is a component of semen, but semen is not only a fluid of the prostate. It is richer than prostatic fluid and contains more complex substances. In short, it is the difference between simple and complex.

2. Prostatic fluid can lubricate the urethra and promote the movement of sperm, but it does not contain sperm, so there is no possibility of conception. However, semen contains a large number of sperm, the number of which is counted in the billions, and the main components of sperm are ribose and protein, which can combine with eggs to form fertilized eggs, and then conceive and pass on to the next generation. However, there are no sperm in prostatic fluid, so no genetic information is stored.

3. The two have different forms. Prostatic fluid mainly contains various enzymes, so it is transparent and not very viscous. Semen is a combination of secretions from multiple glands, so it is opaque in color, usually white, milky white, or light yellow. It is also more viscous. Moreover, because semen contains some prostatic fluid, there is often more semen than prostatic fluid.

    Tips:    

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.
