This article examines the experience of obstetric violence as gender-based violence seen in pregnancy care practices, especially during childbirth in health institutions. In this research work, the configuration of the political subjectivity of women who choose an alternative birth and prepare for it is particularly addressed. The aim is to show the influence of institutional pregnancy and childbirth care through practices such as episiotomy or cesarean section on the construction of meaning in women, in order to make the problem of obstetric violence visible as gender-based violence in which power relations and social control perpetuated over the body are glimpsed. In this way, it highlights the social complexity that is rooted in the fact that it is not recognized by women as violence and where it is necessary to implement the required mechanisms that guarantee a humanized birth far from any form of violence/mistreatment towards the woman and her child.
