Urinary Bacteria May Synthesize Testosterone Near the Prostate, Hinting at Cancer Links
A study shows the urinary tract bacterium Actinobaculum massiliense can convert the steroid precursor DHEA into testosterone, revealing a microbial route to androgen production near the prostate. While not claiming bacteria cause cancer or produce meaningful hormone levels in people, the finding suggests a possible link to androgen-driven prostate cancer and highlights the need for further research into the urobiome’s role in this disease.
