How hormones and metformin may drive gut inflammation in PCOS
Project-003
This project looks at whether high male hormones and the diabetes drug metformin change gut cell energy and inflammation in women with PCOS, which may explain common belly pain, bloating, and bowel changes.

What this research studies
The team uses a hyperandrogenemic rat model that mimics key features of PCOS to study changes in the colon. They measure colon mitochondrial oxidative phosphorylation and mitochondrial reactive oxygen species (mtROS) under high-androgen conditions and after metformin exposure. They will also examine gut bacteria (dysbiosis) and markers of sub-acute inflammation in the colon. Findings will be compared with controls to link these mechanisms to the gastrointestinal symptoms many women with PCOS report.
Who could benefit from this research
Good fit: Women with PCOS who experience chronic gastrointestinal symptoms such as abdominal pain, constipation, diarrhea, or bloating—especially those taking metformin or with signs of high androgens—are the most relevant group.
Not a fit: People without PCOS or those whose gastrointestinal symptoms have causes unrelated to androgen-driven colon changes are unlikely to benefit directly from this research.
Why it matters
Potential benefit: If successful, this work could explain why many women with PCOS have chronic gut symptoms and point to therapies that reduce colon inflammation or improve metformin tolerability.
How similar studies have performed: Prior research has linked PCOS to metabolic problems and gut symptoms, but direct evidence tying androgens and metformin to colon mitochondrial dysfunction is limited and mainly comes from animal studies.
