The most common cause of testicular bleeding in men is due to trauma, such as direct violent blows or falls from height, or riding across the perineal area, which can cause local trauma and bleeding. It can also be seen after medical operations, such as scrotoscopy or after surgery, there will be localized blood leakage, and in severe cases, hematoma can even be formed around the testicles. In addition, it can be seen in testicular tumors, where necrosis of the tumor itself can cause bleeding, resulting in an increase in the size of the testicle or bruising in the scrotal cavity, etc. Patients are advised to go to the hospital for examination to determine the specific cause. The probability of general infection, inflammation or spontaneous bleeding is very small, but bleeding may also occur secondary to systemic coagulation dysfunction, but the bleeding may gradually resolve or disappear with coagulation therapy. In daily life, it is necessary to avoid local blows or trauma to prevent bleeding.
