[|Human|] My husband is 53 and for the first time last night we noticed that his seminal fluid was a dark reddish/brown. We are making him an appointment with the Urologist, but wanted to know if thats the correct medical field for this? And how urgent is it that he be seen?
[|AI|]  Hello, Seeing blood in the semen can make a man anxious. Fortunately, it doesn't always signal a major medical problem. For men younger than 40 with no related symptoms and no risk factors for underlying medical conditions, blood in semen often disappears on its own. But for men 40 and over, chances are higher that blood in the semen needs evaluation and treatment. Blood in the semen is known as hematospermia. Prostate biopsy is the most common cause of blood in the semen. Blood in the semen can be caused by tumors, infections, anatomical abnormalities, stones, or inflammation in many sites throughout the genitourinary system. Hope I have answered your query. Let me know if I can assist you further.
