Association between gut microbiota and primary ovarian insufficiency: a bidirectional two-sample Mendelian...

Area of Science:

• Microbiome research
• Reproductive health
• Genetic epidemiology

Background:

• Primary ovarian insufficiency (POI) is a condition affecting women's reproductive health.
• The relationship between gut microbiota (GM) and POI is not fully understood.
• Investigating potential causal links between GM and POI is crucial for understanding disease mechanisms.

Approach:

• A bidirectional two-sample Mendelian randomization (MR) study was employed.
• Utilized large-scale genome-wide association study data for GM and POI.
• Applied various analytical methods to assess causality and identify potential pleiotropy.

Key Points:

• Eubacterium (hallii group) and Eubacterium (ventriosum group) showed a protective association with POI.
• Intestinibacter and Terrisporobacter were associated with an increased risk of POI.
• Reverse MR analysis indicated no significant causal effect of POI on these gut bacteria.

Conclusions:

• Established a causal relationship between specific gut bacteria (Eubacterium species, Intestinibacter, Terrisporobacter) and POI.
• Highlights the potential role of the gut microbiota in the pathogenesis of POI.
• Further clinical research is warranted to elucidate the mechanisms and therapeutic implications.
