What are the reasons for blood in semen?

Patient's question:

All symptoms are without status, just these past few days

Doctor's answer:

Ejaculate containing blood is called hematospermia. If the semen appears entirely light red, partially light red, or coffee-colored, it indicates the presence of blood, as normal semen should not contain blood components. The causes of hematospermia include:
(1) Inflammation of the reproductive tract, such as prostatitis, seminal vesiculitis, urethritis, epididymitis, prostatic calculi of the spermatic cord, or urethral-bladder calculi.
(2) Obstruction of the seminal tract and cysts.
(3) Tumors and vascular abnormalities.
(4) Systemic factors: hypertension, hemophilia.
(5) Injury to the reproductive tract.
It is recommended that you first relax your mind, avoid excessive sexual activity, maintain regular bowel movements, and seek medical attention promptly. Through scientific testing, the underlying cause can be identified, and targeted treatment can lead to a complete cure.
