Studysummary This paper proposes that gut dysbiosis plays a crucial role in Post-Finasteride Syndrome by possibly contributing to both androgenic and non-androgenic symptoms, and may explain fluctuating symptom cycles better than static genetic explanations.

research Framing the Problem: The Mystery of Post-Finasteride Syndrome and Reasons to Suspect a Microbial Factor

April 2026 in “Zenodo (CERN European Organization for Nuclear Research)”

This paper hypothesizes that gut dysbiosis acts as a key factor in Post-Finasteride Syndrome, potentially explaining its symptom patterns beyond androgen receptor silencing.

research The Evidence for Microbes in the Small Intestine as the Mechanism for Post-Finasteride Syndrome: Self-Reported Case Study

April 2026 in “Open MIND”

This case report suggests that Post-Finasteride Syndrome may involve a sustained imbalance in gut bacteria, with fermenting and hydrogen sulphide-producing bacteria disrupting hormone and mitochondrial functions.

research The Evidence for Microbes in the Small Intestine as the Mechanism for Post-Finasteride Syndrome: Self-Reported Case Study

April 2026 in “Zenodo (CERN European Organization for Nuclear Research)”

This case report proposes that Post-Finasteride Syndrome might be sustained by specific microbes in the small intestine affecting hormone excretion and mitochondrial function, warranting further investigation in a larger cohort.

A SIBO-Mediated Etiology for a Subset of Post-Finasteride Syndrome Cases: Investigating Gut-Derived Toxins

research A SIBO-mediated aetiology for a subset of Post-Finasteride Syndrome cases: investigating gut-derived toxins

February 2026 in “Zenodo (CERN European Organization for Nuclear Research)”

This paper proposes a novel theory that certain symptoms of Post-Finasteride Syndrome may be caused by an overgrowth of hydrogen sulphide-producing bacteria in the small intestine, which acts as a mitochondrial toxin, with implications for treatment targeting the gut microbiome.

research A SIBO-mediated aetiology for a subset of Post-Finasteride Syndrome cases: investigating gut-derived toxins

February 2026 in “Zenodo (CERN European Organization for Nuclear Research)”

This theoretical paper proposes that a subset of Post-Finasteride Syndrome cases may be driven by a gut-derived toxic process involving hydrogen sulphide-producing bacteria, suggesting that the small intestinal microbiome could be a potential target for treating this condition.
