The lifetime ban on blood donation from men who have had sex with men (MSM) has no scientific justification, particularly when other high risk groups are not similarly excluded. Furthermore, the full costs of maintaining the ban often are not taken into account; they need to be tallied in making the risk-benefit decision.
