The Society for Menstrual Cycle Research (SMCR) is an organization dedicated to advancing understanding of menstruation through research, education, discussion, and activism. It aims to serve as a source of guidance, expertise, and ethical perspectives for people interested in the menstrual cycle. SMCR brings together researchers, educators, advocates, and others working across the field of menstruation studies, and shares information about the topic through its website, journal resources, publications, and educational materials.

The Society supports professional and public engagement with menstrual research through conferences, webinars, and online events featuring current scholarship, theory, and activism. Its activities also include conference publications, journal content, research resources, and a blog. Educational offerings include a menstruation fact sheet, resources for girls, suggested readings, and links to affiliate organizations. SMCR also provides opportunities for activist engagement and publishes position statements on relevant issues. Membership is available, with information about benefits, dues, and joining provided on the website. The Society’s next announced conference is planned for summer 2027 at Chalmers University of Technology in Gothenburg, Sweden.
