This Week - S : Semen Worries
It's unusual to find blood in your semen when you ejaculate, but try not to worry - it's usually only temporary and the cause is rarely anything serious.
The semen may be blood stained, brownish-red in colour or have a pink tinge.
This page is intended to give you a better idea of the possible causes, but you shouldn't use it to diagnose yourself with a condition - always see your GP for a proper diagnosis.
In many cases, no obvious cause can be found for blood in the semen and it will clear up by itself.
Common causes of blood in semen include:
These problems generally aren't serious and many will get better on their own without treatment, or after a course of antibiotics or anti-inflammatory painkillers.
Less common causes
Less often, blood in the semen can be a result of:
These conditions are more serious and may require specialist treatment.
Seeing your GP
Your GP will try to determine whether the cause of the blood in your semen is likely to be serious or not.
They'll need to consider a number of things, such as:
- how many times you've noticed blood in your semen
- whether you have any other symptoms
- your age
- your medical history
They may also need to carry out a number of simple tests, including:
- checking your blood pressure
- an examination of your genitals and abdomen (tummy)
- a rectal examination (where your doctor inserts a finger into your bottom)
- urine and blood tests
If you're younger than 40, have only noticed blood in your semen once or twice, and tests don't suggest you have a serious underlying condition, you shouldn't need a hospital referral.
However, if you're over 40, have persistent or recurrent symptoms, or tests have suggested a potentially serious underlying cause, your GP should refer you to a urologist (specialist who treats problems of the urinary system).
A further assessment with a urologist may involve having a biopsy of your prostate gland or a scan, such as an ultrasound scan.
Treating blood in semen
The treatment your GP or urologist recommends will depend on what they think is the underlying reason for the blood in your semen.
In many cases, particularly if you have no other symptoms or the blood in your semen was an isolated incident, no treatment is necessary and the problem will usually resolve on its own.
If a clear reason is identified, the treatment you're offered will depend on the specific cause. For example, you may be given antibiotics to treat an infection and cysts may need to be drained with a needle.
If there's a serious underlying cause, such as a blood clotting disorder or cancer, you'll be referred to an appropriate specialist for any necessary treatment.
