The vast majority of cases are caused by seminal vesiculitis or prostatitis, especially seminal vesiculitis. The seminal vesicle has the characteristic of having a thin and transparent wall. When inflammation occurs, the wall of the seminal vesicle thickens, swells, and becomes congested. The seminal vesicle fluid inside also contains blood due to congestion and bleeding. As the seminal vesicle gland contracts during ejaculation, the discharged semen carries blood and turns red.
Self diagnosis of hematospermia
1. Normal semen color: The newly ejaculated semen is semi transparent or gray white, and after the semen liquefies on its own, it becomes semi transparent milky white. If there is no ejaculation for a long time (more than 1 month), the semen may also turn pale yellow.
2. Exclusion of hematuria: Hematuria refers to the presence of blood in the urine, resulting in initial hematuria, terminal hematuria, or complete hematuria. The urine color turns pink, or bright red, or dark red, or contains blood clots.
Blood sperm can be divided into primary and secondary blood sperm. The so-called primary hematospermia refers to the presence of red blood cells in semen, which is the only symptom. That is to say, the possibility of hematuria in the patient is ruled out, and there are no symptoms of urinary tract infection or irritation. Routine tests such as urine analysis have not found any special findings. Primary hemospermia is a self-limiting disease, in which symptoms disappear without treatment, and some patients no longer show hemospermia after improvement. If the symptoms of hematospermia change, accompanied by urinary tract infections such as frequent urination, urgency, and pain, or if hematuria occurs, timely follow-up should be sought.
