Not infrequently, prostatitis patients are shocked to notice blood or blood clots in their semen. On a number of occasions in recent years, frightened patients have written to the newsgroup or webmaster wondering what this means. A typical doctor's reaction is that blood in semen is not uncommon in prostatitis and is not necessarily a cause for alarm.
In writing to patients, your webmaster has commented that blood in semen might be viewed about the same way one would view blood in nasal mucus when one had a bad cold or sinus infection. It certainly is a sign of problems, but it's not thing to go into a panic about. Good medical care is called for in any case.
Blood in semen is also seen after the beginning of a series of prostate drainages. The pressure of the drainages, and the "popping" of clogged acini, can result in some temporary bleeding as tiny blood vessels are ruptured. Again this is worth noting, but not cause for undue alarm. Bring it up to your doctor, but don't be surprised if he or she says not to worry about it.

My doctor gave me a vigorous prostate message where I got a tablespoon of EPS. However, I noticed I have been seeing blood in my ejaculate. Is this normal?

I have seen bloody EPS and semen in many of my patients and should resolve after successful eradication of the infection. Cancer which is rare should be ruled out and your doctor is aware of these.

By the way, have you felt an almost relief of pressure or pain or freer urination after the drainage of a tablespoonful of EPS.

No, actual my abdomenal pain is worse. My epidiymus has also become swollen after the prostate massage.

Yes, a small blood vessel was possibly injured. I would not worry about it unless the blood does not clear up in a few days.

Worsening of symptoms after a bloody massage suggest a mild form of acute prostatitis and/or exacerbation of semen infection.

I have CP (and associated erectile dysfunction). Having seen three different Urologists myself and noted similar futile experiences by so many others on the newsgroup, I am now just waiting for some research to be done before seeking treatment.

I have had 2 Cystoscopys, each followed by a Biopsy. These tests, along with Ultrasound tests have not found any sign of cancer. My PSA remains constant at about 5.7, I assume because of the infection.

I would prefer to just wait until research determines an appropriate treatment for CP, rather than to undergo more tests that could do more harm than good. My question is whether I should be overly concerned about bloody semen. Although the semen is usually rich in blood content, tests have never found any blood in my urine.

Can I afford to wait a year for more research to be done? I am just asking for an opinion and will take responsibility for my own decisions.

Dear (name deleted),

The diagnosis of CP and seminal vesiculitis is relatively simple. Be happy that your tests for cancer of the prostate is negative. I presumed that cystoscopy done to you also ruled out bladder neck constriction.

Bloody semen is associated with CP and/or semen infection. Your semen should be cultured as well as EPS. Any doctor can do this for you and prescribe the proper antibiotics based on cultures and/or empirically.

A correspondent with prostatitis has blood clots in his urine. They appear periodically. He has a variety of examinations that haven't revealed their source. Does anyone have any suggestions?

Blood clots periodically appearing in the urine from one who has had a variety of examinations ruling out bladder or kidney sources, is part of the manifestations of prostate and/or semen infection,

If his prostate has been found normal based on urologists criteria of an infection and/or semen infection, those areas may still be infected and the most likely source of blood.

Dear (patient 3)

I have already posted recently the procedures to diagnosed a genitourinary tract infection including semen. By having the proper diagnostic procedures should settle the diagnosis and you should be less confused.

(Comment by a urologist on the newsgroup on 1/3/98):
What this sounds like is not necessarily prostatitis, but is hemospermia--defined as the presence of blood in the ejaculate. Hemospermia is an almost always benign self-limiting condition that differs from prostatitis in that it has usually no lower urinary tract symptoms, sexual disturbances, or pain. It usually goes away, but if it persists should be worked up to rule out prostate cancer (DRE and PSA) and possibly a TRUS to r/o a cystic abnormality or the like. Drug use should be examined to rule out something that may cause a bleeding phenomenon, and bleeding/clotting parameters should be examined. Again, if blood in the ejaculate is the only symptom, I don't think that you can be said to have prostatitis--I hope this helps.
