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.
Male prostate and frequent urination problems are a very common occurrence for aging men. In fact only a small percentage of the male population makes it through life without having difficulty urinating at some point. However BPH is not always the culprit. Urinary tract or kidney infections are also causes of frequent urination in men. These are serious issues that need to be dealt with immediately. If left untreated, urinary tract and kidney infection can spread and do serious damage.
