  In Argentina, Florencia Luna, Eduardo Rivera López and Arleen Salles have developed several lines of research in bioethics. Initially, some books with Spanish translations of leading papers in the  field[55] have been published, aiming to introduce into Spanish-speaking societies important issues such as problems raised by genetic knowledge and genetic manipulation, euthanasia, abortion, reproductive rights, the principle of autonomy and the patient-physician relationship, justice and the right to health, experimentation on human subjects, organ transplants, etc. But soon these philosophers developed their own work in the field, shifting from translating the work of others to producing their own original  works[56]. Luna (2006) focuses her research on vulnerable subjects, i.e. “people living in deprivation, oppression, and powerlessness—conditions that are all too common for many Latin Americans” (Luna 2006: 1). Vulnerable subjects pose urgent questions to a moral philosopher given paternalistic attitudes based on wide-spread illiteracy, denial of women’s reproductive rights, extremely restrictive legal circumstances with respect to abortion, and lack of sexual education and contraception information. Difficulties found in biomedical research with vulnerable subjects involve a lack of respect for research subjects, e.g. when researchers hide relevant information from the subjects, fail to request their informed consent, or take their case history without consent. Luna also addresses the question of post-trial obligations with experimental subjects, patents, and the intellectual property of biomedical  findings.[57] Rivera López (2011) deals with classical ethical questions such as euthanasia, the challenges posed by new technologies such as assisted reproduction, organ transplants and genetic manipulation, but also addresses questions of distributive justice on health resources and services, medical technologies, the moral problem of selling organs for transplant, among other issues.
