Gut Bacteria and Testosterone Levels

Here is one result of a crazy observation made during a different study: Male rats fed a probiotic showed youthful levels of testosterone and intestinal inflammation. This study confirms that effect and briefly goes into how and why.


“Feeding of [one probiotic strain] was previously shown to … lower systemic inflammation.” The reason is that the surface of your intestines become less inflammed when this organism is around in sufficient population.


Generally speaking, your intestinal walls are unhappy when certain strains of bacteria are not present. This results in higher overall levels of inflammation (which increases horizontal gene transfer rates, chronic disease rates, and accelerated aging).
