The prostate is a small gland in the pelvis of men. It is located behind the pubis, in front of the rectum, and below the urinary bladder. Very close to this are the lymph nodes (which are part of the lymphatic system).
The lymphatic system protects us and helps the body fight off infection and disease. This system is made up of a number of ducts called lymphatic vessels, which connect lymphatic glands to one another. Circulating within these ducts we can find lymph, which transports the cells whose job it is to destroy the substances that can damage our organism to the different lymphatic glands.
The prostate's size and functioning depend on the level of testosterone (a hormone produced in the testicles) in the body.
The prostate is in charge of producing seminal fluid (the liquid that protects and transports sperm). The prostate also synthesizes prostate-specific antigen (PSA).
