Structure And Function Of The Prostate

Prostate - One of the major organs of the reproductive system of males. This small body size of a walnut and shape resembling a chestnut fruit is important for the normal composition of semen, and in addition, it produced some biologically active substances. Violation of the functions of the prostate is an infringement of the semen, in particular, its viscosity - the parameter is important for sperm motility.

Location Prostate
As already mentioned, the prostate is similar in its form the fruit of the chestnut. The body in essence, is the gland (prostate gland). The prostate is located below the bladder in his neck, covering the thickness of its initial Department urethra. In addition, it is adjacent to the rear of the rectum, which is of considerable importance in practice. One side of the prostate are muscle fibers, which raises the anus.

Functions Prostate
The main function of the prostate is to develop a special transparent, slightly alkaline liquid - prostatic juice, which is about 10 - 30% of the volume of semen. The rest of the sperm consists of a liquid, which is produced the seminal vesicles - two saccular formations on the sides and rear of the prostate. As we have said, prostatic juice has an alkaline reaction, it is necessary to neutralize the acid reaction of the vaginal environment.
The Structure Of The Prostate
The prostate consists of two parts - right and left. Sometimes, doctors point out and the average share, for the convenience. Gland itself consists of two tissues: glandular (main), whose cells and produce the main prostatic juice, and muscle. Glandular tissue in the prostate brought young slices (acini), among which are fibers and muscle tissue. The function of muscle tissue in the prostate is that it promotes the outflow of the prostatic fluid in ducts, thus preventing stagnation and the development of prostatitis. The glandular tissue of the prostate is composed of so-called glandular epithelium.

As already mentioned, the prostate is its thickness covers the initial division urethra. Meaning, stuffy nature of this arrangement is that the two channels directly into the urethra (the urethra), open ducts of the prostate.
Location male urethra in the thick of prostate tissue plays a very important role in the occurrence of manifestations of such diseases as prostate adenoma, when there is a proliferation of prostate tissue (benign). Thus there is a compression of the urethra and difficulty urinating.
Prostatic Juice
In the composition of prostatic juice include many biologically active compounds: biogenic amines, citric acid (citrate), cholesterol, phospholipids, as well as proteolytic enzymes, and zinc. In addition, prostatic juice is a nutrient medium for the sperm when they leave the male body. Another important component of prostatic juice - prostate-specific antigen (PSA).
Normal operation of the prostate is dependent upon the principal male hormone - testosterone, which is responsible for male sexual characteristics. Testosterone is produced mainly by the testes in certain quantities; it is produced and adrenal glands.
Pathology Prostate
Among the diseases of the prostate identified two large groups: the inflammatory diseases - prostatitis, which in turn can be both acute and chronic, and neoplastic diseases. Among neoplastic diseases can mention two: the prostate adenoma, which is a benign swelling of mainly fibro-muscular tissue and prostate cancer, which is a malignant tumor originating from the glandular epithelium of the prostate.
On the structure of mortality from prostate cancer in men is 10% of all cancers. Prostate cancer is one of the leading causes of death in older men.
For example, mortality from prostate cancer among young men in the age of 45 years is insignificant and is approximately 3 cases per 1 million people. In contrast, in old age (after 70 years), this figure rises to almost 400 times and has $ 1300 of cancer deaths per 1 million people. The growth rate of this disease is rising around the world.
