Microbiome as a predictor of implantation

Area of Science:

• Reproductive Medicine
• Microbiome Research
• Genetics and Genomics

Background:

• The female urogenital microbiome plays a crucial role in reproductive health.
• Understanding microbiome composition is key to improving assisted reproductive technology (ART) outcomes.
• The vaginal microbiome is accessible and reliably assessed, unlike the debated endometrial microbiome.

Purpose of the Study:

• To review current research on the female urogenital microbiome as a predictor of successful embryo implantation.
• To explore the association between vaginal microbiome composition and ART success.
• To discuss the challenges and future directions in studying the endometrial microbiome.

Main Methods:

• Literature review of recent research on the female urogenital microbiome.
• Analysis of studies correlating vaginal microbiome with ART outcomes.
• Discussion of methodologies for microbiome assessment, including proteomics and metabolomics.

Main Results:

• Lactobacillus crispatus is associated with a healthy female genital tract.
• Vaginal microbiome dysbiosis is linked to ART outcomes, including implantation and pregnancy.
• Restorative approaches for vaginal dysbiosis show promise for improving ART success.

Conclusions:

• The vaginal microbiome is a significant predictor of ART success.
• Further research is needed to confirm the existence and role of an endometrial microbiome.
• Future studies should integrate multi-omics approaches and virome analysis for a comprehensive understanding.
