The prostate is a gland that is part of the male reproductive system and is located in front of the rectum just below the bladder. The primary role of the prostate gland is to squeeze fluid into the urethra when sperm spurts out through the penis during sexual climax.

As a man ages
The prostate gets bigger as a man gets older. This is an inevitable sign of aging, just as similar to having gray hair or wrinkles. This condition is known as Benign Prostatic Hyperplasia (BPH).  When the prostate gets larger, the surrounding layer of tissue stops it from expanding. This causes the prostate gland to press against the urethra. This in turn causes the bladder wall to become thicker resulting in the frequent urge to urinate even when there is a small amount of urine.
