What are the symptoms of hemophilia in males?

Male hemophilia patients generally experience varying degrees of bleeding or bruising of the skin and mucous membranes, accompanied by pallor of the skin and mucous membranes. Some patients may develop localized redness, swelling, warmth, and pain following injuries to joints such as the ankle, shoulder, or elbow, which can lead to joint stiffness, deformity, and impaired limb mobility in later stages. Additionally, some patients may suffer from severe bleeding after trauma or surgery, with bleeding that is difficult to control.
