What is it?
Blood in the semen (haematospermia)
If you see blood in your semen, you should contact your GP for further advice although it is unlikely that there is a worrying underlying cause.
Your GP will normally provide reassurance about blood in the semen. Most GPs will perform some simple, baseline tests. You may be commenced on antibiotics or anti-inflammatory drugs to treat presumed infection / inflammation (the commnest cause of blood in the semen).
It is not normally necessary for you to be referred for more detailed investigations, in hospital, unless your prostate gland feels abnormal, there is associated blood in the urine or your PSA blood test is abnormal.
