Hello, the cause of hemospermia is not only prostatitis and seminal vesiculitis, but blood in semen is called hemospermia. If it only happens occasionally, it may be caused by sexual excitement or strenuous exercise. Generally, you only need to rest for about a week to recover on your own. However, if it occurs repeatedly, it should be noted that the common causes of hemospermia are: (1) reproductive tract inflammation, such as prostatitis, seminal vesiculitis, urethritis, epididymitis, spermatic prostate stones and bladder stones. (2) Obstruction of vas deferens and cysts. (3) Tumors and vascular abnormalities. (4) Systemic factors: hypertension and hemophilia. (5) Reproductive tract injury, etc. Therefore, it is suggested to further analyze the condition, such as semen analysis, urogenital X-ray, color Doppler ultrasound, etc., and take treatment measures according to the examination results. Pay attention to hygiene in life, avoid spicy stimulation in diet, quit smoking and drinking, avoid sedentary or staying up late for a long time, and avoid excessive sexual stimulation. I wish you the best of health!
