This chapter is a literature review which aims to highlight the most critical aspects discussed in the surrogacy scholarship, whose interdisciplinarity represents a major value for the advancement of the sociological understanding of the phenomenon. The literature review is organized into three levels. The first is that of individual experience, which includes some of the main ethnographies that have tried to explain the motivations that push people, aspiring parents but above all the surrogates, to undertake this procreative path. At the second level, that of the social structure, there are three recurring themes: inequality—explained through the concept of stratified reproduction—which permeates the relationships between the parties and upon which the surrogacy market proliferates; the transformation of procreation into a productive process in which life is commodified and the woman reduced to her womb; the transformation of kinship from a natural fact to a cultural product, which is defined by one’s own intentions, and the parallel fragmentation of motherhood into several figures. At the third level, that of representation, there are the studies that discuss how surrogacy is told by the media, and the studies that provide a systematization of the different feminist perspectives on the subject.
