The relation between time and gender has been extensively discussed in feminist theory, from Simone de Beauvoir to recent studies of queer temporality and crip time. In this article, I explore gender as “lived time” in relation to a pressing feminist issue: social recognition of the chronic illness endometriosis (endo). Based on my interviews with individuals diagnosed with endo, I argue that lived time can be studied by approaching becoming as a dynamic process or flow of recognition, creating certain temporal patterns in the lifeworld. I propose the concept of “endo time” as a phenomenological conception of the lived time of endo. I identify three temporal patterns that characterize endo time: waiting time (I), cyclical or chronic time (II), and sedimented time (III). The analysis contributes to feminist philosophy by detailing how gender appears as a specific orchestration of time. Because of its connection to feminized pain and menstrual flow on the one hand and social recognition on the other, endo presents an illuminating case for exploring the relation between gender, recognition, and lived time.
