The prostate gland goes through two main stages of growth during a man's life. The first sees fairly rapid growth during the early years of puberty with the prostate roughly doubling in size. The second stage of growth starts in a man's mid-twenties and this is a much slower phase of growth which then continues throughout life.

For the vast majority of men this second phase of growth does not cause any problems at all until they are well into their sixties or seventies when the symptoms caused by the now enlarged prostate will begin to appear and a visit to the doctor will reveal the presence of nothing more than a simple enlarged prostate. In medical terms, your doctor will say that you are suffering from benign prostatic hyperplasia, benign prostatic hypertrophy or BPH.

Each day a huge number of men (something in the region of 13,000 in the US alone) call to see their doctor with a variety of problems associated with urination and come away having been told that they are suffering from an enlarged prostate.

Benign prostatic hyperplasia, benign prostatic hypertrophy or BPH, to give it its proper medical names, is an extremely common and treatable problem seen in many men over the age of 65 and is suffered by as many as half of all men in their sixties and ninety percent of men in their seventies and eighties.

But what causes this condition which is a simple part of the natural aging process and is as common as your hair turning grey with age?
