We are assisting in participant recruitment for a clinical trial investigating whether menstrual blood can help identify biological markers linked to chronic endometritis or changes in the reproductive-tract microbiome when compared with endometrial biopsy results. Your participation will contribute to research aimed at developing less invasive ways to understand fertility and uterine health.
