The prostate is part of the male reproductive system. It is a small gland about the size of a walnut.The prostate lies between the penis and bladder, surrounding the urethra. Its function is to produce a thick clear fluid that mixes with sperm to form semen. The prostate is regulated by the hormone testosterone.

With increasing age, the prostate gland often enlarges due to a non-cancerous condition called benign prostatic hyperplasia. However, when abnormal and malignant cells begin to form in the prostate, prostate cancer will develop.
