Rydström works within a post-constructionist framework to critically explore the nature of menstruation, which many perceive to be a strictly female bodily function despite many scholars’ recognition that menstruators are of various gender identities. In challenging menstruation as a cisnormative phenomenon, the author explores various menstrual experiences among trans people and argues that cis and trans menstruators come to matter differently. More specifically, menstrual activism, public bathrooms, menstrual products, and the healthcare sector are problematized as areas wherein trans menstruators are Othered. Finally, Rydström calls for a recognition of the multiplicity of menstrual experiences as they exist and a degendering of menstruation as phenomena.
