Yes, metformin can help regulate cytokines in PCOS by reducing inflammation and improving insulin sensitivity. Women with PCOS often experience chronic low-grade inflammation, driven by elevated pro-inflammatory cytokines like TNF-α and IL-6. This contributes to insulin resistance, hormonal imbalances, and long-term risks like type 2 diabetes and heart disease.
Metformin works by:
- Lowering TNF-α, IL-6, and CRP levels: Reduces inflammation and improves metabolic health.
- Blocking the mTOR pathway: Suppresses inflammatory cytokine production.
- Reprogramming immune cells: Shifts them to a less inflammatory state.
- Improving insulin sensitivity: Reduces fasting insulin levels and promotes hormonal balance.
These effects not only alleviate PCOS symptoms, such as irregular cycles and infertility, but also lower long-term risks of diabetes and cardiovascular disease. Metformin is most effective when tailored to individual needs, and options like oral or topical formulations can help manage side effects.
For personalized care, platforms like Oana Health provide convenient, telehealth-based solutions, offering treatments like metformin and combination therapies.

How Metformin Affects Pro-Inflammatory Cytokines in PCOS
Metformin helps reduce inflammation in PCOS by targeting specific pro-inflammatory cytokines.
Metformin and TNF-α Reduction
Studies reveal that women with PCOS often have elevated levels of TNF-α, a cytokine produced by peripheral blood B cells. This increase contributes to insulin resistance and hormonal imbalances. Laboratory experiments demonstrate that treating these B cells with metformin at a concentration of 12.5 mM reduces TNF-α production. Metformin achieves this by inhibiting mTOR phosphorylation, which plays a role in metabolic reprogramming. Additionally, it remodels mitochondria, decreasing oxidative stress and glucose uptake through the downregulation of Glut 1/4, HIF1α, and c-Myc levels. Animal studies using a DHEA-induced PCOS mouse model support these findings, showing reduced TNF-α expression in splenic B cells and improvements in PCOS symptoms.
"Together, TNF-α-producing B cells are involved in the pathogenesis of PCOS, and metformin inhibits mTOR phosphorylation and affects metabolic reprogramming, thereby inhibiting TNF-α expression in B cells, which may be a new mechanism of metformin in the treatment of PCOS." - Na Xiao et al.
This reduction in TNF-α lays the groundwork for metformin's broader influence on other inflammatory markers like IL-6 and CRP.
Effects on IL-6 and CRP Levels
Metformin's ability to lower TNF-α also extends to its effects on IL-6 and CRP, two other markers closely associated with inflammation in PCOS. A meta-analysis revealed that metformin reduces CRP levels by an average of 1.23 mg/L, with the most noticeable benefits seen in obese women. It also significantly lowers IL-6 levels, suggesting a positive impact on insulin metabolism .
In addition to IL-6 and CRP, another cytokine - GDF-15 - offers valuable insights into metformin's role in managing PCOS.
The Role of GDF-15 in PCOS and Metformin Treatment
Growth differentiation factor 15 (GDF-15), a member of the TGF-β cytokine family, has gained attention in PCOS research. Elevated GDF-15 levels in women with PCOS may reflect metabolic stress, but they also point to its potential anti-inflammatory properties. Studies have observed increased GDF-15 levels in patients treated with metformin, suggesting it could serve as both a marker of metabolic improvement and a therapeutic target .
How Metformin Reduces Inflammation
Metformin helps combat inflammation in PCOS by influencing key cellular pathways that control immune responses and inflammatory activity throughout the body.
Blocking the mTOR Pathway
One of metformin’s main anti-inflammatory actions involves shutting down the mTOR (mammalian target of rapamycin) pathway, which plays a central role in cell growth and immune regulation. This pathway operates through two complexes, mTORC1 and mTORC2, and is linked to conditions like inflammatory diseases, autoimmune disorders, and diabetes.
Metformin disrupts mTOR activity in several ways. It activates AMPK (AMP-activated protein kinase), which blocks RAPTOR (regulatory-associated protein of mTOR), effectively halting mTORC1 activity. This process depends on TSC2 and AMPK activation. Additionally, metformin inhibits mTORC1 through the IGF1 and insulin signaling pathways and activates p53, which further suppresses mTORC1.
By targeting this pathway, metformin reduces the production of inflammatory cytokines, setting off a chain of anti-inflammatory effects. It also alters immune cell metabolism, further dampening inflammation.
Shifting Immune Cell Metabolism
Metformin reprograms immune cells by altering their energy production processes. It modifies mitochondrial function and inhibits Glut 1/4, HIF1α, and c-Myc, reducing these cells’ ability to produce inflammatory cytokines. This metabolic shift forces immune cells to rely on alternative energy sources, naturally lowering their inflammatory output.
Additionally, metformin increases glycolytic lactate and TCA cycle intermediates in splenic B cells, pushing their metabolic activity toward a less inflammatory state. These changes collectively create an environment where immune cells are less likely to trigger chronic inflammation, a common issue in PCOS.
Reducing Inflammation Throughout the Body
The cellular changes brought about by metformin lead to broader reductions in inflammation across the body. This is particularly important for women with PCOS, who often experience chronic low-grade inflammation due to insulin resistance, hyperinsulinemia, and elevated IL-6 levels.
Clinical research highlights metformin’s ability to lower inflammatory markers like IL-6 and TNF-α, improving vascular health and reducing cardiovascular risks . It also decreases polymorphonuclear (PMN) rolling flux and adhesion, while reducing levels of ICAM-1, E-selectin, IL-6, and TNF-α.
Metformin further aids inflammation control in obesity by encouraging macrophages to shift toward the anti-inflammatory M2 type, a process linked to AMPK activation. It may also reduce tissue damage by limiting NETosis - a mechanism where immune cells release inflammatory networks.
These anti-inflammatory effects complement metformin’s ability to improve metabolic and reproductive symptoms in PCOS. By fostering a healthier inflammatory state, metformin supports better metabolic function, enhanced insulin sensitivity, and relief from PCOS symptoms.

Clinical Benefits of Metformin for Women with PCOS
Metformin's anti-inflammatory properties provide measurable improvements for women managing PCOS, addressing both immediate symptoms and long-term complications. By targeting chronic inflammation, this medication not only tackles metabolic challenges but also helps reduce the risk of future health issues. Let’s explore how these benefits unfold across metabolic, reproductive, and cardiovascular health.
Improvements in Metabolic and Reproductive Health
Metformin enhances insulin sensitivity, leading to a reduction in fasting serum insulin levels and body weight. This, in turn, decreases androgen levels, easing symptoms like acne and excessive hair growth (hirsutism). Since insulin resistance affects 50%–70% of women with PCOS, metformin's ability to lower fasting serum insulin by approximately 40% and reduce body weight by an average of 5.8% is significant.
On the reproductive side, metformin plays a key role in regulating menstrual cycles and boosting fertility. Studies show it increases ovulation rates and improves clinical pregnancy outcomes. For example, a study involving 676 infertile women with PCOS found live birth rates of 7.2% with metformin alone, 23% with clomiphene citrate, and 26.8% when the two were combined. Metformin is particularly beneficial for women with anovulatory infertility who are non-obese or resistant to clomiphene citrate. Additionally, it may reduce ovarian hyperstimulation syndrome in IVF patients and serve as an alternative to birth control for managing hyperandrogenism.
Beyond these immediate reproductive benefits, metformin also addresses long-term metabolic risks associated with PCOS.
Reducing Risks of Heart Disease and Diabetes
Metformin’s anti-inflammatory effects extend to lowering the cardiovascular and diabetes risks tied to PCOS. Affecting approximately 5.2% of women, PCOS is linked to conditions like hypertension, dyslipidemia, type 2 diabetes, and obesity - all significant contributors to heart disease. By improving insulin sensitivity and lipid profiles, metformin helps reduce cardiovascular risk. It also shows promise in lowering the likelihood of developing type 2 diabetes.
Research indicates that metformin may improve endothelial function in women with PCOS. Starting metformin therapy early can also address chronic low-grade inflammation, a key factor in preventing the progression of metabolic and cardiovascular complications later in life.
For women with PCOS, metformin offers a targeted approach to managing symptoms, improving quality of life, and mitigating risks associated with chronic inflammation and metabolic dysfunction.
