If you see blood in the 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. It is not normally necessary for you to be referred for more detailed investigations unless your prostate gland feels abnormal, there is associated blood in the urine or your PSA blood test is abnormal.
The commonest cause of blood in the semen is low-grade infection or inflammation in the seminal tract (particularly in the prostate gland)
Your GP should work through a recommended scheme of assessment for patients with blood in the semen. This will normally include some or all of the following:
Your GP will ask you questions about any recent symptoms (especially pelvic pain), any associated matters (including any drugs you are taking) and will enquire about smoking habits. You should inform your GP if you are taking blood-thinning drugs (warfarin, dicoumarin) or if you take anti-platelet treatment (aspirin, dipyridamole, clopidogrel). If the blood in the semen is painful or associated with blood in the urine, it is likely that he/she will arrange referral to a urologist.
A general physical examination will be performed, together with a rectal examination and assessment of your testicles. Your blood pressure may be measured as part of this examination.
The usual tests performed are:
The actual tests performed will be left to your GP’s discretion but it is common to measure kidney function, clotting factors, prostate-specific antigen (PSA) and to check the blood cells for anaemia or other problems.
A urine test will normally be sent for infection. Your GP may commence you on antibiotics whilst awaiting the result of this test. If there is blood in your urine, fresh urine may be sent to the laboratory for microscopic examination, to look for cancerous cells.
Testing the semen for infection is not normally performed because harmless bacteria are often found in semen and are not the cause of any infection.
Your GP may arrange an ultrasound scan of your kidneys and bladder, pictured right. This is more likely to be arranged by the urology department who may also request a rectal ultrasound scan of your prostate gland and seminal vesicles.
Most patients with blood in the semen have low-grade prostate, urethral or seminal vesicle inflammation which requires no specific treatment and often resolves spontaneously.
Although there are many potential causes for blood in the semen, it is often difficult to identify a clear cause. Those most often found are:
It is very unusual for men with blood in the semen to require urological referral
Your GP will reassure you that the condition usually improves by itself. If the blood in the semen persists, your GP will normally prescribe a 6-8 week course of antibiotics or anti-inflammatory drugs. Urological referral may be considered if:
This will involve an outpatient appointment when some or all of the following assessments will be performed:
This may involve one or more of the following:
this is a telescopic check of the bladder. It is performed under antibiotic cover & local anaesthetic using a small, flexible telescope which allows the clinic doctor to see inside your bladder (pictured). If you have concerns about this or have experienced problems with local anaesthetic in the past, you should ask about having your examination under a brief general anaesthetic (i.e. whilst you are asleep). When your tests have been completed, the medical staff will advise you on what to do next:
If an abnormality requiring further treatment is detected, the medical staff will advise you on what treatment is necessary. If no specific abnormality is found, you should keep a careful eye on your symptoms and report any further bleeding to your GP who will be informed of the result of your assessment.
