The prostate is one of the least studied parts of the male reproductive system. The gland is located just below the bladder in front of the rectum, and wraps around the upper part of the urethra -- the tube that carries urine from the bladder through the penis. It is mostly composed of muscular and glandular tissues and produces a thick, milky-white fluid that is part of semen, the liquid ejaculated during sexual activity.
To function properly, the prostate requires adequate amounts of certain hormones, including testosterone produced by the testicles and other hormones from the pituitary and adrenal glands.
Most males rarely think about their prostate until something goes wrong with it. When it does, this small gland can cause major disruptions in a male's life. Prostate problems typically surface after the age of 50. Younger men however, may experience prostatitis, a bacterial infection that can cause painful or difficult urination, and is treated with antibiotics.
