Period Blood as a Hidden Health Window for Women's Wellness

Researchers are turning menstrual blood into a noninvasive diagnostic tool that could reveal endometriosis and other uterine-related conditions, while also indicating risks for diabetes, autoimmune diseases, ageing, and environmental exposures. Startups like NextGen Jane are identifying endometriosis biomarkers in menstrual samples, and others such as Qvin and theblood are testing at-home kits to assess diabetes risk and infections from period blood. The field faces challenges including sample variability, stigma, and limited funding for women's health research, but advances from MIT and emerging menstrual biobanks are accelerating progress toward quicker diagnosis, better prevention, and a broader understanding of female health.
