Is this trial a fit for you?

Likely a good fit

Women aged 18-40 with infertility who are scheduled for diagnostic hysteroscopy and endometrial biopsy and have suspected or confirmed chronic endometritis.

Probably not a fit

Women without CE, or those whose infertility is driven by factors other than CE, may not benefit.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This prospective cohort study will estimate how common chronic endometritis is among women undergoing infertility evaluation and see if antibiotic treatment improves reproductive outcomes. It will compare hysteroscopic findings with lab confirmation of CE and explore the uterine bacterial landscape to understand potential links to fertility and pregnancy. Histology and CD138 staining will confirm CE, while documented hysteroscopic markers will be evaluated for diagnostic value. Participants are women aged 18-40 undergoing diagnostic hysteroscopy with endometrial biopsy, diagnosed with CE, and willing to receive antibiotic treatment and follow their reproductive outcomes.

Why it matters

Potential benefit: If successful, antibiotic treatment could improve implantation and pregnancy chances for women with CE.

How similar studies have gone: Other studies suggest CE can affect fertility and that addressing it may improve outcomes, but results vary and this approach is still being clarified.
