Discovering a new paradigm: Gut microbiota as a central modulator of sexual health

Figure 2 Psychological factors in the relationship between gut microbiota and sexual health. Sexual health is closely linked to the gut microbiota, which regulates hormonal balance and psychological well-being through the microbiota-gut-brain axis. This system influences sex hormone production and metabolism, such as testosterone and estrogen, which are essential for healthy sexual function. Dysbiosis can lead to hormonal imbalances, inflammation, and endothelial dysfunction, negatively affecting sexuality. Additionally, microbiota impacts psychological health, contributing to issues such as performance anxiety and decreased libido, reinforcing its key role in sexual well-being.
