Specific gut microbiota may increase the risk of erectile dysfunction: a two-sample Mendelian randomization study

Microbiome Signatures identifies and validates condition-specific microbiome shifts and interventions to accelerate clinical translation. Our multidisciplinary team supports clinicians, researchers, and innovators in turning microbiome science into actionable medicine.

Karen Pendergrass

Karen Pendergrass is a microbiome researcher specializing in microbiome-targeted interventions (MBTIs). She systematically analyzes scientific literature to identify microbial patterns, develop hypotheses, and validate interventions. As the founder of the Microbiome Signatures Database, she bridges microbiome research with clinical practice. In 2012, based on her own investigative research, she became the first documented case of FMT for Celiac Disease—four years before the first published case study.

What was studied?

The study investigated the causal relationship between gut microbiota and the risk of erectile dysfunction (ED) using a two-sample Mendelian randomization approach based on genetic data from large GWAS studies.

 

Who was studied?

Genetic data were analyzed from 223,805 participants in Europe for ED and 18,340 participants from 24 cohorts for gut microbiota.

 

What were the most important findings?

The study identified a causal relationship between six specific gut microbes and the occurrence of ED. Notably, Ruminococcaceae UCG-013 was associated with a reduced risk of ED, while Lachnospiraceae, Lachnospiraceae NC2004 group, Oscillibacter, Senegalimassilia, and Tyzzerella3 were associated with an increased risk.

 

What are the greatest implications of this study?

The findings provide new insights into the potential role of gut microbiota in developing and preventing ED. This could lead to novel therapeutic strategies targeting the gut microbiome to manage or prevent ED, extending beyond traditional treatments such as pharmacotherapy. Further research is required to explore the mechanisms by which these microbiota influence ED, which could help develop microbiome-based treatments.
