Sources: 9. Developments: 2. Research into menstrual fluid is expanding as scientists seek to utilize biological samples for improved diagnostic capabilities in women’s health. In the United Kingdom, the CycleTrack study has launched to establish a large-scale biobank. By collecting menstrual fluid samples and real-time health data, researchers aim to better understand conditions such as endometriosis, fibroids, and heavy menstrual bleeding. This initiative is part of a broader effort to reduce the time required for women to receive effective treatment for heavy bleeding. Concurrently, biotechnology developments are highlighting the potential of menstrual blood to serve as a non-invasive indicator for various conditions, including cervical cancer, diabetes, and vitamin D deficiency. Efforts in this field aim to address the significant delays in diagnosing endometriosis, which currently can take between five and 12 years for many patients. ## Timeline ### 2026-09-23: Menstrual blood research offers new insights into women's health Researchers and biotech startup NextGen Jane are studying menstrual blood to improve diagnostics for conditions like endometriosis, cervical cancer, and diabetes. 6 sources. https://clstr.news/cluster/menstrual-blood-research-offers-new-insights-into-womens-health ### 2026-08-26: CycleTrack study launches largest menstrual fluid biobank in the UK The UK-based CycleTrack study is creating the world’s largest menstrual fluid biobank to improve diagnosis and treatment for heavy menstrual bleeding and conditions like endometriosis. 3 sources. https://clstr.news/cluster/cycletrack-study-launches-largest-menstrual-fluid-biobank-in-the-uk --- Cite as: Menstrual fluid research and diagnostic development.
