As men age, many experience prostate gland enlargement. This condition is known as benign prostatic hyperplasia BPH. The prostate gland surrounds the urethra, the hollow tube that carries urine out of the body. When the prostate gets bigger, it can squeeze or partially block the urethra, which leads to problems urinating. BPH is quite common in older men. Although the causes of BPH are not entirely understood, some researchers have investigated whether hormonal changes and cell growth as men age could be related to the development of the condition.
BPH is an enlarged prostate. The first occurs early in puberty, when the prostate doubles in size. The second phase of growth starts around age 25 and goes on for most of the rest of a man's life.
Benign prostatic hyperplasia—also called BPH—is a condition in men in which the prostate gland is enlarged and not cancerous. Benign prostatic hyperplasia is also called benign prostatic hypertrophy or benign prostatic obstruction. The prostate goes through two main growth periods as a man ages.
