Doctor's answer:

Hello, blood in semen is called hematospermia. If the semen appears entirely light red or 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 infections of the reproductive tract, such as prostatitis, seminal vesiculitis, urethritis, epididymitis, prostatic calculi of the spermatic cord, and ureteral or bladder stones. It is recommended that you visit the department of reproductive infections at a hospital, avoid excessive sexual activity, maintain regular bowel movements, and undergo scientific testing to identify the underlying cause. Targeted treatment based on the identified cause can lead to a complete cure.
