All men have the organ known as the prostate gland. This muscular organ is compared, size-wise to that of the average walnut. The prostate is located right in front of the rectum, just below the man’s bladder. A normal prostate gland measures at less than two inches long and they tend to weight approximately one ounce. The prostate gland is located around the urethra, the organ that is known for the transportation of urine and sexual fluids through the penis to exit the body.
The prostate is made up of a large number of very small glands. These glands are protected by the prostatic capsule, a very fibrous tissue. Around the prostatic capsule is a thick layer of fat offering more protection. The prostate gland is made of two lobes – one on the right and one on the left. The apex of the prostate gland is located further away from the bladder while the base is located just under the bladder. The back of the prostate gland is called the posterior and the front of the prostate gland is the anterior.
There are five zones associated with the prostate. The peripheral zone is deemed the largest zone. It contains an estimated 75 percent of all prostate glands. It is also the location most likely to be affected by prostate cancer, where chronic prostatitis will most likely occur, and where a large number of needle biopsies take place. The transition zone is the most likely scene of benign prostatic hyperplasia. The anterior zone is one-third of the entire prostate and made up of smooth muscle. Lastly, the central zone is where the remaining 25 percent of the prostate glands are. To prevent the semen from heading backwards into the bladder, there is the preprostatic tissue.
One of the most common cancers that men face all over the world is prostate cancer. There is no one cause of prostate cancer but there are factors that elevate a man’s risk of contracting it. Men who are older than 65 and men that come from a family with a history of prostate cancer are more susceptible. Common signs of prostate cancer include the need to urinate often, inability to urinate, difficulty in either stopping and/or starting urine flow, a feeling of not emptying the bladder, burning sensation while urinating and painful ejaculation. This is because the prostate becomes enlarged. There are numerous types of prostate cancer treatments available, some more invasive than others.
The prostate’s main function is the production of a large portion of the fluid known as semen. The semen is what carries sperm when it exits the penis. When the sperm is produced inside the testicles, it travels up to the prostate via the vas deferens. The sperm is added into the semen in the prostate. Once orgasm is reached, the semen is pushed from the prostate to the urethra by the ejaculatory ducts. The urethra leads all the way to the tip of the penis when the semen then exits.
Urination may also be affected by the prostate. Many individuals are aware of the fact that the kidneys are the responsible organ in terms of creating urine. When the urine exits from the kidneys and into the ureters, it empties into the bladder. When the bladder reaches capacity, the urine is sent through the urethra and out of the penis. Because the prostate rests right at the bottom of the bladder, it encircles around the urethra at the precise location where the urethra connects to the man’s bladder. When the prostate expands, either because of prostate growth or prostate cancer, the prostate becomes a tight ring around the urethra. It then restricts the ability of the urine to leave the bladder and enter into the urethra.
