What is benign prostatic hyperplasia?
Benign prostatic hyperplasia (BPH), is the term for an enlarged prostate gland.
The prostate is normally a walnut sized gland located beneath the bladder sitting in front of the rectum in men. It is made up of two types of tissue, epithelial cells that form glands interspersed with smooth muscle cells. Surrounding this is a fibrous tissue layer called the prostatic capsule. The urethra (tube that transports urine and semen out the body) passes from the base of the bladder through the prostate to the tip of the penis. The exact role the prostate plays in human physiology is not entirely known, however, it certainly plays a major part in sexual function and fertility.
Approximately 25 to 30% of the volume of the semen comes from the prostate, 60 to 65% of the fluid from the seminal vesicle (two organs attached to the prostate) and very small portion from the testicles (where the sperm is produced). The prostate also secretes many enzymes, one of which is called prostate specific antigen, or PSA. Also secreted in high concentrations is zinc.
