The prostate belongs to the male genitals. It is one of the central organs of urology. Diseases of the prostate are quite common. The World Health Organization (WHO) estimates that almost every man in the Western industrial nations will seek medical treatment for prostate troubles at least once in his life, and one in three will undergo prostate surgery in the course of his life.

Normally, the prostate is the size of a chestnut and weighs about 20-30 grams. It is located below the bladder, at the bottom of the pelvis, and surrounds the urethra in a circular shape. In the prostate, the urethra and spermatic ducts (vasa deferentia) converge. The prostate is a gland and produces a secretion that provides the sperm cells with a cocktail of minerals and enzymes, which is was what makes a successful reproduction possible in the first place.

The prostate increases in size with age due to age-related hormone shifts. This basically benign enlargement narrows the urinary tract, which results in discomfort in urinating. As a rule, the respective symptoms do not occur suddenly but begin gradually and increase over time. In addition to this benign enlargement, tumours (prostate cancer) may develop. Inflammations (prostatitis) are also possible.
