The prostate gland is part of the male reproductive system, adjacent to the male bladder and surrounding the urethra. Common problems with the prostate include benign prostatic hyperplasia (BPH), acute and chronic bacterial prostatitis and chronic prostatitis (non-bacterial) and prostate cancer. This presentation is about benign prostatic hyperplasia or hypertrophy (BPH) in men. Whose prostate enlarges? Enlargement of the prostate gland first begins at puberty, and after the age of 25 hyperplasia kicks in again and stays with a man for the rest of his life. Typically, it rarely causes clinical symptoms below the age of 40. However, if a man lives to 85 years of age, more than 90% will experience symptoms, and one-third of them will be bothered by these symptoms. What keeps the prostate growing? Regret! The exact mechanism by which a man’s prostate keeps growing throughout his life is not yet understood. Hormones such as testosterone, dihydrotestosterone, and estrogen (men have estrogen too) may all be involved in the regulation of prostate growth. Practical observations such as vasectomy (male sterilization) and sexual behavior have not increased the clinical risk of BPH. And it is not clear why some people develop symptoms while others do not.
