What this trial studies

This observational study aims to explore the correlation between endometriosis and intra-tissue microbiota by collecting various biological samples from participants. Women aged 18-52 with confirmed endometriosis will be recruited, and samples such as serum, vaginal swabs, cervical mucus, feces, and endometrial tissue will be analyzed through sequencing and laboratory experiments. The goal is to better understand the role of microbiota in the pathogenesis of endometriosis, which remains unclear.

Why it matters

Potential benefit: If successful, this study could lead to new insights into the causes of endometriosis and potential new treatment strategies.

How similar studies have gone: While the investigation of microbiota in relation to endometriosis is a relatively novel approach, similar studies have shown promising results in other tumor types.
