Is hemophilia related to blood platelets?

No, hemophilia is not related to blood platelets. Hemophilia is a genetic disorder in which the blood does not clot properly due to the deficiency of specific clotting factors, namely clotting factors VIII or IX. Platelets play a different role in blood clotting by clumping together and forming a plug at the site of injury, but they are not directly affected by hemophilia.
