Hematospermia even if the seminal vesicle glands are fine may be due to prostate diseases, bleeding disorders, and excessive sexual intercourse. 1. Prostate disease: inflammation, stone, injury, tuberculosis, schistosomiasis, tumor, etc. of the prostate gland are common causes of hematospermia. 2. Bleeding disorders: Bleeding disorders that cause an increase in vascular fragility and changes in blood clotting mechanisms, such as purpura leukemia and scurvy, can cause hematospermia. 3. Excessive sexual life: frequent and violent penile friction caused by excessive sexual life can also cause capillary damage in the genital tract and hematospermia. When blood semen occurs, you should go to regular hospitals to clarify the cause of the disease, and under the guidance of the doctor for treatment.
