The prostate is a walnut-sized gland found deep in the pelvis in men. It is located just under the bladder and surrounds a tube (urethra) through which urine exits when we urinate. The prostate is rich in nerves and muscle. The function of the prostate is not clearly understood, though it produces 20% of the fluid found in the semen and other substances that are thought to help sperm survive and make penetration easier during sexual intercourse. However, these substances are not essential for fertility. In addition, the prostate is a source of other hormones and enzymes, but these are also not crucial for men to stay healthy. It is common for our prostates to enlarge as we age. Because of where the prostate is located, men may experience problems with urination as it enlarges.
At What Age Is BPH Likely?
It is difficult to know how many men have BPH because we as men often do not have symptoms even though our prostates have enlarged. However, estimates have been made based on examining a representative sample of men in the Untied States:
- Over 30% of men in their 50s- and 46% of men in their 70s have moderate to severe BPH.
- In men who have had their bladder function tested, over half have diminished rates of urinary flow or are unable to fully empty their bladder.
- More than one in three Caucasian men over the age of 50 may have some symptomatic BPH.
- In European men, it has been estimated that 24% aged 50-59 and 40% aged 70-79 have symptoms of BPH.
