Is this trial a fit for you?
✓Likely a good fit
Ideal candidates include women aged 20-45 with a history of recurrent miscarriages or those who have failed to conceive after multiple IVF attempts.
✕Probably not a fit
Patients with uncorrected uterine anomalies, untreated hydrosalpinx, or known autoimmune diseases are unlikely to benefit from this study.

What this trial studies
This observational study aims to explore the confounding factors associated with chronic endometritis and the potential therapeutic benefits of antibodies targeting plasma cells in women experiencing reproductive failure. Eligible participants will be recruited from the IVF and miscarriage clinic at the Prince of Wales Hospital/CUHK medical centre. The study will involve endometrial sampling during the mid-luteal phase, with hormonal assessments and ultrasound evaluations to ensure proper timing and conditions for sampling. Immunohistochemical techniques will be employed to quantify plasma cells in the endometrial tissue, which may provide insights into the role of chronic endometritis in infertility.
Why it matters
Potential benefit: If successful, this study could lead to improved understanding and treatment options for women facing infertility due to chronic endometritis.
How similar studies have gone: While similar studies have explored aspects of chronic endometritis, this specific approach focusing on plasma cells and their therapeutic implications is relatively novel.
