Understanding the evolution and function of menstruation in women

Bases Évolutives Et Fonctionnelles De La Menstruation Chez Les Femmes - 2

NA · Institut National de la Santé Et de la Recherche Médicale, France · NCT05412771

This study is trying to understand how menstruation works by looking at tissue samples from women having surgery and comparing them to similar samples from primates to find out what genes are involved.

What this trial studies

This study aims to investigate the genetic and cellular mechanisms underlying menstruation by collecting endometrial tissue samples from women undergoing surgery for benign conditions. The research team will perform transcriptome sequencing and open chromatin profiling on these samples, comparing the findings with similar data from non-human primates. The goal is to identify genes and regulatory elements that have evolved in menstruating species, providing insights into the biological processes involved in menstruation. Additionally, the study will establish 3D organoid cultures for further functional validation of the findings.

Who should consider this trial

Good fit: Ideal candidates are women aged 18 to 50 who are menstruating and scheduled for hysteroscopic surgery for benign conditions.

Not a fit: Patients who have a history of certain cancers, endometriosis, or have recently been pregnant or used hormonal treatments may not benefit from this study.

Why it matters

Potential benefit: If successful, this research could enhance our understanding of menstruation and lead to improved treatments for related reproductive health issues.

How similar studies have performed: While the specific approach of this study is novel, similar studies have successfully explored genetic factors in reproductive health.
