Why? Of course, because the prostate is useful!

Part1What county is Prostate? Where is it?
To find out what the prostate is, the pheasant and men's hospital advertisement will not tell us, we have to find out where the prostate is first.
But according to my estimation, you who are scratching your mobile phone do not know what part of your body the prostate gland, the male "gland of life", is in.
In fact, the prostate gland is just below the bladder, it is like a fist, "held", that is, wrapped around the root of the urethra (where the urethra just came out of the bladder). For example, if the bladder is a reservoir and the urethra is a river, then the prostate is the gate that connects the reservoir to the urethra.

In addition, the back of the prostate is also close to the rectum, which is why the urological surgeon must enter from the chrysanthemum when he gives the patient a digital prostate examination.

What is the role of Part2 Prostate?
Well, after going around in such a big circle and clarifying where the prostate is, what is the role of the prostate?
1. Control urination
The first is the role of controlling urination, we just mentioned when talking about the position of the prostate, the prostate is equivalent to the floodgates of the reservoir, so what is the function of the gates? Boiling and releasing water from reservoirs depends on the floodgates, as does the human body's urination.
"At that time, the wind peed ten times, and now the tailwind diaper wet shoes" is to describe the elderly men's urination is no longer as smooth as it was then, so why does this happen? It is because with age, men are more and more likely to have the problem of prostatic hyperplasia, that is to say, the floodgates of the prostate are "aging and difficult to open", and the channel for urination is not smooth, so the urine flow is not so powerful.
2. Secretory function
The second function of the prostate is related to this "gland" of the prostate.
Glands are actually the meaning of glands, and the most familiar glands of the human body may be the breast. The mammary glands have the role of secreting milk, and milk nourishes every one of our lives.
So since the prostate is called a gland, does it also have a secretory effect?
You guessed right, the prostate is one of the few glands in the human body, there are two kinds of secretory functions inside and outside, endocrine function may be more difficult for everyone to understand, then we mainly talk about exocrine function, that is to say, the prostate will secrete a liquid, we should not be unfamiliar, this liquid is called prostate fluid.
We often call "semen", more than 90% of which is the prostate fluid produced by the prostate. Prostatic fluid is like water, and sperm is like fish, it is with the escort and nutrition of prostatic fluid that sperm can be smoothly excreted from the body to complete the major mission of reproduction.
So, we go back to the original question of the article - why can't we cut off the prostate because of the prostatitis, or why humans have evolved to the present, why has not the prostate organ eliminated, is because the function of the prostate is very important for men, let's imagine, if a man does not have a prostate, then his urination is uncontrollable, and the urine will flow out of itself unconsciously. At the same time, because there is no nourishment and escort of prostatic fluid, it is difficult for sperm to be excreted and Miss Egg has a perfect encounter.
That's terrible isn't it?
Well, I'm a doctor of urology, and finally, I wish you a bright heart.
