A simple look inside the uterus may reveal hidden inflammation — no lab needed
NCT ID NCT07733713
First seen Jul 29, 2026 · Last updated Jul 30, 2026 · Updated 1 time
Summary
This study asks whether visual signs seen during a hysteroscopy — a camera exam of the uterus — can reliably detect chronic endometritis, a long-term inflammation of the uterine lining. About 100 women already scheduled for hysteroscopy as part of their fertility care will take part. Researchers will compare the visual findings with a lab count of CD138-positive immune cells from a tissue sample to see if the two methods agree closely enough to skip the lab test.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If hysteroscopic signs correlate well with lab results, doctors might diagnose chronic endometritis faster and less invasively during routine exams.
- What could go wrong
- This is an observational study, not a treatment trial. The correlation may be weak, meaning lab tests would still be needed for reliable diagnosis.

Who can take part
This study's own entry requirements. Only the study team can say for certain whether you qualify.
Who is studied
Women aged 18-46 years referred for office hysteroscopy with endometrial biopsy at Centro A.M.B.R.A. (Palermo, Italy), for any clinical indication including recurrent implantation failure, recurrent pregnancy loss, or other reasons. All examinations are performed during the early-to-mid proliferative phase (cycle days 6-12) of a spontaneous, non-progestin-exposed menstrual cycle. Approximately 100 participants will be prospectively enrolled and registered; an additional approximately 20 patients evaluated before study initiation constitute a separate pilot cohort and are not included in this population.
