In this reflection work I examine the notion of biological citizenship in light of the discussions on the right to abortion, exposed in the processing of law 20.030 on therapeutic abortion in three causes in Chile. The genealogy of this modality of citizen production and its emergence in the LGBTQ movements in the 90s and its inheritances for current feminist movements, especially in the criticism of heterosexual power and new forms of reappropriation of knowledge and technologies, are questioned. The discourses of both selfstyled physicians for life and women's movements are analyzed below to reveal the ways in which women's bodies and reproductive capacities are subject to disputes and tensions. It is concluded that the feminist biological citizenships put in tension, challenged and reconfigured the territories of government of the biopolitical practices and technologies, as well as the feminist policies of the body and the subjectivity towards novel forms of resistance in which the biological body is central.
