What is the prostate? Smaller text Larger text

The prostate is a small, walnut-sized gland found only in men. It lies in the pelvis just below the bladder exit, surrounding the tube known as the urethra. Its job is to make some of the fluid in the semen which men ejaculate on orgasm.

Despite its modest size the prostate can cause serious problems in middle age. Like all illnesses, the faster any problems are diagnosed, the better the prognosis is likely to be.
