Hypothesis

How does the physical separation in uterus didelphys affect endometrial microbiome and inflammation?

Conclusion

The study found significant microbiome variations between the two uteri in uterus didelphys, despite similar endometrial receptivity patterns.

Supporting Evidence

  • Endometrial receptivity analyses showed similar receptive states in both uteri.
  • Differential markers of chronic endometritis were observed, with the right uterus showing a higher prevalence.
  • Significant differences in microbiome composition were found, particularly in the right uterus.
  • The right uterus had a less favorable microenvironment with lower lactobacilli levels.
  • Both uteri shared a similar metabolomic profile but exhibited variations in specific metabolites.

Takeaway

Women with a double uterus can have different bacteria and inflammation in each side, which might affect their chances of getting pregnant.

Methodology

Endometrial samples were collected from both uterine cavities during the mid-secretory phase and analyzed for microbiome, metabolome, and immunological features.

Potential Biases

The study's findings may be influenced by the patient's unique medical history and the presence of multiple complicating factors.

Limitations

Results are based on a single case and may not be generalizable; potential contamination in microbiome analysis could affect findings.

Participant Demographics

A 36-year-old woman with primary infertility and a BMI of 31.5 kg/m².
