First, what is the prostate?
The prostate is a male-specific gonad (the female is a prostate without a prostate), located between the bladder and the posterior urethra, connecting the bladder and the urethra.
you can ask prostate disease and treatment
,We will give you a satisfactory result,about prostate disease and treatment
There is a urethra and an ejaculatory duct in the prostate. Since the opening of the semen from the ejaculatory duct is located on the fine sputum in the prostate, the prostate is the final processing and maturity of the semen. It is located at the forefront of the entire male reproductive system, so it is called the prostate. .
Every male has a prostate. The prostate is the name of an organ. It is only when prostate hyperplasia, prostatitis and prostate cancer occur.
Second, the function of the prostate
The main functions of the prostate include:
1. Secretion of prostatic fluid, which constitutes an important part of semen, stimulates sperm motility and survival rate, and promotes the combination of semen and egg;
2. Synthesis of hormones such as 5α-reductase and prostaglandin to promote the synthesis of androgen (dihydrotestosterone);
3. The prostate surrounds the urethra and is normally closed. When urination is required, the smooth muscle of the prostate relaxes, helping the urine to flow out of the body (like a sluice).
In theory, when there is inflammation in the prostate, it will affect the amount, quality and composition of semen, which may cause infertility.
Prostatitis, if not treated in time, can lead to prostatic hyperplasia, oppression of the bladder outlet, so that the urine can not be completely empty, residual urine appears.
Residual urine is a good medium for bacterial reproduction, and the defense mechanism of bladder mucosa is impaired, so it is easy to cause urinary tract infections such as pyelonephritis. At this time, if the treatment is not complete, it will be developed by nephritis, hydronephrosis, etc. And later developed into uremia.
