The central purpose of this investigation, developed in Management studies, specifically, within the field of career studies, was to understand and analyze the influences of social origin on the development of the medical career, based on the reports of experiences lived by gynecologists and obstetricians with consolidated careers, working in the city of Rio de Janeiro. The life history research method was used to obtain the biographical narratives of the doctors in order to reach subjective, cultural, social, and relational aspects of their lives and careers. The contributions of Pierre Bourdieu s approach to career studies underpinned the theoretical framework. The findings of the medical field demonstrated an overlap of social phenomena that were related to race, class, and gender, in addition to the interviewees perception of the changes that have been occurring in this field. Furthermore, the reports showed that, in this group of doctors, differences in social origins influenced the development of their careers. The economic and cultural capitals were the main ones that outlined the trajectories —life and career— and contributed most to increase or decrease opportunities in the medical field. Economic capital delimited choices and paths during graduation and career development, evidenced in choices motivated by professional improvement or pressured by financial need, which resulted, for example, in more or less time dedicated to medical education, or even more, in opening their own practice in the initial or intermediate phase of their career. The cultural capital inherited and acquired in life trajectories, connected to social capital, became, in the context of the medical field, career capital, as it contributed to increase the opportunities that doctors had in their careers and observed in the different positions occupied that reflected the unequal volumes of these capitals. The study findings revealed aspects of the career habitus that can restrict or expand career-related strategies and investments, highlighting the inheritance of the medical career habitus, received from medical relatives, combined with the cultural capital of the parents when it became evident the importance of social relationships, strategies, and tactics that would be most suitable for developing and achieving a solid and successful career in medicine, even before entering the undergraduate course. The medical career capitals highlighted in the trajectories were: social relationships and interactions (cultural and social capital); medical education time (cultural capital and economic capital); diplomas from institutions (cultural and symbolic capital); international academic experience (cultural and economic capital). Finally, we highlight that the contexts of the doctors social origins made the paths more or less fluid, reflecting the influence of the different volumes and structures of capitals which enhanced or mitigated the individual merit.
