This issue is a scholarly contribution to these sorts of discussions centered on girls and periods. The issue features eight articles that consider girlhood and menstruation from a variety of perspectives: in young adult literature, in online teen magazines, in healthcare, in activism, and as deeply personal, embodied experience. We see this issue creating space to talk seriously, critically, and from multiple perspectives about an experience steeped in cultural and political misunderstanding and misrepresentation.The articles in this issue blend personal reflection with scholarly analysis to discuss menstruation among trans youth, in Gaza, among youth with eating disorders, representations of menstruation in media, and more.
