In almost all countries, health providers and ministries embrace the same core ethical principles: Do No Harm, Do Good, Respect Autonomy and Do Justice. Yet these principles are not always applied to sexual and reproductive health. In fact, in many places, reproductive health services are under attack, and some constituencies are unmoved by appeals about women’s rights, human rights and public health. This session will explore whether the core principles of medical and health ethics could provide a new and powerful angle from which to advocate for controversial health services, reach marginalized populations and, ultimately, save lives. The event will be convened by the Center for Health, Ethics and Social Policy and PSI.
