Enlarged Prostate Symptoms and Causes. In men, urine flows from the bladder through the urethra. BPH is a benign (noncancerous) enlargement of the prostate that blocks the flow of urine through the urethra. The prostate cells gradually multiply, creating an enlargement that puts pressure on the urethra -- the chute through which urine and semen exit the body.
