The prostate is a walnut-sized gland whose primary function is to help in reproduction. Given its location in front of the bladder, however, enlargement of the prostate, known as benign prostatic hyperplasia (BPH), can constrict the flow of urine and impair emptying of the bladder, leading to urinary frequency, urgency, and having to urinate at night.
BPH primarily affects men over the age of 40, of all races and ethnic backgrounds. In fact, approximately 80% of men over the age of 70 have some degree of BPH. Fortunately, not all men will suffer bothersome symptoms. Currently, it is estimated that 25%-50% of men with an enlarged prostate have some degree of bothersome urinary symptoms and can benefit from some form of medical or surgical treatment from a urologist.
