The article defines prostate gland to hopefully give you a better understanding of prostate gland. Prostate gland can be defined in many ways. The complicated definition given on wikipedia is as follows: The prostate is a compound tubuloalveolar exocrine gland of the male mammalian reproductive system. In simple words, the prostate gland is a walnut-sized gland in the male reproductive system that is located just below the bottom of the bladder and in front of the rectum.

The prostate gland is made of three lobes that surround the upper part of the urethra and the tube that carries urine and semen from the other sex glands (the testicles and seminal vesicles). It is supported anteriorly by the puboprostatic ligaments and inferiorly by the urogenital diaphragm. The main job of the prostate is to produce semen, the fluid that carries sperm. It also produces a protein called prostate-specific antigen that may be found in an increased amount in the blood of men who have prostate cancer, benign prostatic hyperplasia, or an infection of the prostate gland.

Prostate infections or prostatitis occurs most often in men aged 30-50 years but can occur in older men. There are several different kinds of prostatitis, including nonbacterial prostatitis - the most common form - pros-tatodynia, and chronic and acute bacterial prostatitis. Prostatitis can cause a variety of symptoms, including a frequent and urgent need to urinate and pain or burning when urinating. It is often accompanied by pelvic, groin or low back pain. If the prostate grows too large, it squeezes the urethra. This may slow or stop the flow of urine from the bladder to the penis. Left untreated, infection can spread to the testicles and epididymis (tubules in back of the testis) and, in severe cases, destroy the prostate gland.

Prostate cancer is one of the most common cancers affecting older men. It often grows very slowly, without causing major problems. There is an excellent chance of successful treatment of prostate cancer if it is detected early. However, some treatments for prostate cancer can cause other problems, such as controlling urination or erection problems. Because of its genetic linkage, prostate cancer is more frequent in patients with a strong family history of prostate cancer. Likewise, people who smoke, African American males, and patients who consume a diet high in animal fat or high in chromium have increased risk.

Urination and ejaculation may provide defense against prostatic infection by flushing the urethra. The prostate also secretes an antibacterial substance known as prostatic antibacterial factor into the semen that provides some defense against infection. Prostate infections are extraordinarily difficult to cure because antibiotics do not accumulate in high concentrations in the prostate. So most men have to take appropriate antibiotics for many months and their partners have to take the same antibiotics for a much shorter duration.
