For men with blood in the ejaculate, the more common cause is vesiculitis, an inflammation of the reproductive system caused by acute bacterial or certain pathogenic infections, the seminal vesicles will be congested and edematous, resulting in the phenomenon of blood in the ejaculate. When blood in the ejaculate occurs, patients are advised to check the semen routine to clarify whether there are clear infectious factors in the semen, and at the same time should be promptly treated with antibiotics, which can be administered orally or intravenously. If a patient has a malignant tumor of the reproductive system that causes blood in the ejaculate, the patient should conduct a tumor investigation after ruling out infectious factors, and may undergo a first examination with CT or local ultrasound to clarify whether there is a foreign body or a new organism causing the bleeding.
