Vaginal microbiome and recurrent pregnancy loss

Area of Science:

• Reproductive Biology
• Microbiome Research
• Immunology

Background:

• Recurrent pregnancy loss (RPL) affects many couples trying to conceive.
• The vaginal microbiome plays a vital role in maintaining a healthy reproductive environment.
• Lactobacillus species dominance is associated with preventing pathogens and maintaining vaginal homeostasis.

Purpose of the Study:

• To review recent findings on the vaginal microbiome and its association with RPL.
• To explore the potential of vaginal microbiota as biomarkers for pregnancy health and RPL risk.
• To summarize immune and metabolite changes in RPL and discuss limitations.

Main Methods:

• Literature review of recent studies on vaginal microbiome and RPL.
• Analysis of findings related to Lactobacillus spp. and their protective role.
• Synthesis of data on biomarkers, immune responses, and metabolites.

Main Results:

• Altered or reduced Lactobacillus spp. in the vaginal microbiome are linked to RPL.
• Vaginal microbiota show potential as predictive biomarkers for pregnancy outcomes.
• Immune responses and metabolite profiles are altered in RPL cases related to microbiome dysbiosis.

Conclusions:

• The vaginal microbiome composition is a significant factor in recurrent pregnancy loss.
• Targeting the vaginal microbiome may offer new strategies for preventing RPL.
• Further research is needed to fully understand and utilize vaginal microbiota for reproductive health.
