It surrounds the tube that carries urine from the bladder. The gland is the size of a walnut and also produces some of the fluid that makes up semen.  If a problem occurs  within the gland it can affect your sex life, or cause difficulties with passing urine.

PSA is a prostate specific antigen made by your prostate and released into your bloodstream. Raised PSA can indicate a problem with your prostate including:

  • Prostate enlargement
  • Urinary infection
  • Prostate cancer

A PSA test is a blood test that can be carried out at your GP surgery. Note that 2 out of 3 men with raised PSA levels do not have prostate cancer.*

If your test shows raised PSA, your GP may recommend further testing or a biopsy.
