Reframing how the uterus works in heavy menstrual bleeding

Reframing Endometrial Physiology by Advanced Integrated Research

Observational University Hospital Southampton NHS Foundation Trust · NCT07557992

This project will try wearable sensors, MRI scans, and blood/tissue samples to find measurable uterine changes linked to heavy menstrual bleeding in people aged 18–45 with and without heavy periods.

What this trial studies

This observational study will enroll about 130 participants with and without heavy menstrual bleeding and collect wearable electrophysiology data during menses, pelvic MRI scans, and biosamples. Objective measures of blood loss will be combined with device recordings and imaging to identify physiological signatures of heavy bleeding. Data from two sites will be integrated to look for reproducible patterns in uterine contractility, endometrial repair, and tissue composition. The goal is to generate candidate biomarkers that could support scalable, non-invasive diagnostics.

Who should consider this trial

Good fit: Ideal candidates are people aged 18–45 who have menstrual periods, with or without heavy bleeding, who are not pregnant or breastfeeding and who have not used hormonal treatments in the past two months.

Not a fit: People who are pregnant or breastfeeding, have known uterine malignancy, severe anemia requiring urgent treatment, acute gynecological emergencies, cannot undergo MRI, or cannot provide informed consent are excluded and would not benefit from participation.

Why it matters

Potential benefit: If successful, this work could lead to non-invasive tests using wearables or imaging to diagnose causes of heavy menstrual bleeding and help guide treatment choices.

How similar studies have performed: Elements such as MRI and electrophysiology have shown promising signals in small studies, but combining imaging, wearables, and biosamples for heavy menstrual bleeding is relatively novel and not yet widely validated.
