Over the course of the twentieth century, a series of changes occurred in the understanding of childbirth, which went from being a natural reproductive phenomenon belonging to the female, domestic sphere to a professional medical matter handled in an institutional setting. Through procedures like the use of anesthesia, Cesarean sections, ultrasound and other techno-scientific interventions, rapid and significant improvements and changes took place in the health and life of society and of women. The medicalization of childbirth in the early twentieth century was part of a broader process of constructing the state and institutionalizing the patriarchy that was common throughout the region.
