###Human: I get bloody semen with clots and pain in my right testicle. What is my problem? ###Assistant: Hello. Hematospermia (blood in semen), is fairly common. Generally it is not considered as a sinister sign. There are whole list of possibilities for this theoretically, but once we ensure it is not due to sinister cause and rule out treatable causes say like infections we do not beyond that as it will not affect the management. Sinister causes mainly prostate and testicular cancers. At your age prostate cancer is extremely unlikely but need to ensure no testicular problem. With your symptoms with testes, you need another scan to be on safe side as the scope for examination to be conclusive. I suspect you have epidydimal cysts which are very common and can cause pain, etc. So if the scan does not show anything other than this, I would not worry about it at all. I think the rash is completely unrelated to this or any of your urological problems. Nor the rash or hematospermia is related to old history of chlamydia. Since you have not had any other urinary symptom, I would not worry much about other tests related to urinary tract. However, I would also recommend sending semen for culture to see any infection in it. Lastly about prostate cancer virtually unheard in your age. Finger examination of prostate, PSA blood test and MRI scans of prostate are the screening tests in general. But not something I would recommend if testes scan comes back normal and if you are still worried an MRI then will be helpful as last resort. Idiopathic. Testicular pathology. Ultrasound scan of testes. Ideally an examination of genitals including prostate by a clinician. Semen culture. Idiopathic. Hematospermia. With reports.
