The first step toward understanding how the prostate affects your health is to learn what the prostate is and how it functions. It is surprising how little many men know about such an important part of their anatomy.

The prostate is an important segment of the male reproductive system. It is a gland that is located in the lower abdominal cavity, just below the bladder, in front of the rectum and behind the pubic bone. It partially surrounds the urethra. The urethra is the channel that carries urine to the penis from the bladder and it runs right through the prostate.

A healthy prostate is about the size of a walnut, weighs approximately 1 ounce and is shaped similar to a donut.

There are 'seminal vesicles' that are attached to the prostate. They produce a protein that mixes with prostatic fluid which forms semen. How this works is that tubes from the testicles carry sperm up to the prostate where sperm is mixed with the seminal vesicle and prostatic fluids. This fluid is ejaculated during orgasm through ejaculatory ducts that connect to the urethra. In addition, the prostate helps to control the flow of urine.

Nearly every man will experience some type of prostate problem during his lifetime. Men who are over forty-five may experience an enlargement of the prostate. While this is not a problem in itself, it is uncomfortable and can be a forerunner to other more serious maladies which we will discuss further.

The prostate actually continues to grow throughout life, but grows very slowly after the age of twenty-five. Enlargement of the prostate is part of the normal aging process due to hormonal changes and usually does not become a serious problem until a man reaches sixty years of age.
