This book paints a comprehensive portrait of Mexico's system of assisted reproduction first from a historical perspective, then from a more contemporary viewpoint. Based on a detailed analysis of books and articles published between the 1950s and 1980s, the first section tells the story of how the epistemic, normative, and material infrastructure of the assisted reproduction system was built. It traces the professionalization process of assisted reproduction as a medical field and the establishment of its professional association. Drawing on ethnographic material, the second part looks at how this system developed and flourished from the 1980s up to 2010, its commercialization process, how the expansion of reproductive services took place, and the messages regarding reproductive technologies that circulated within a wide discursive landscape. Given its scope and methods, this book will appeal to scholars interested in science and technology studies, reproduction studies, history of medicine, medical anthropology, and sociology.
