ArgumentThis study contributes to the discussion on the development of eugenics in Central-Eastern Europe by tracing the way that eugenic ideas entered into medical decision-making in Hungary. Through a case study that reviews the professional argumentation of the gynecological management of tuberculosis pregnancies, this paper shows that the subordination of individual reproductive rights to state interests was influenced by the ideas of eugenics, which had begun to enter into the professional public health discourse. A eugenically informed morality was envisioned, to guide decision-making in the interest of the Hungarian “race.” This biopolitically important morality can be viewed as an early influence on the formulation of biological citizenship. Leading figures were divided on how to ensure such morality: some scholars argued that education is the key, others thought that the state, and state actors, should act radically in the interest of the population and decide on behalf of the individual. Radical methods, such as the termination of pregnancies and sterilization of women, were among the practices of gynecologists. Although abortion and sterilization were not widespread and never became official therapeutic solutions for tuberculosis pregnancies, they were nonetheless part of a discourse that preceded the eugenic institutions of the interwar years.
