Metformin for PCOS Introduction

Metformin: A Promising Treatment for Polycystic Ovary Syndrome (PCOS)

Polycystic Ovary Syndrome (PCOS) is a common endocrine disorder affecting women of reproductive age, characterized by hyperandrogenism, ovulatory dysfunction, and polycystic ovaries. It is associated with insulin resistance and metabolic abnormalities, contributing to long-term health risks such as type 2 diabetes, cardiovascular disease, and endometrial cancer. Metformin, a biguanide class drug primarily used in the management of type 2 diabetes, has emerged as a potential therapeutic option for PCOS due to its insulin-sensitizing properties.

How Metformin works for PCOS

Metformin acts by enhancing insulin sensitivity, reducing hepatic glucose production, and increasing glucose uptake by peripheral tissues. In the context of PCOS, insulin resistance plays a pivotal role in the pathophysiology of the syndrome. Hyperinsulinemia stimulates ovarian androgen production and disrupts the normal regulation of the hypothalamic-pituitary-ovarian axis, leading to anovulation and menstrual irregularities. By improving insulin sensitivity, metformin can indirectly reduce hyperandrogenism and restore ovulatory function. You can access Metformin online for affordable prices at Oana here.

Clinical efficacy of Metformin for PCOS

Several clinical studies have demonstrated the beneficial effects of metformin in women with PCOS. Metformin treatment has been associated with a reduction in circulating androgen levels, improvement in menstrual regularity, and an increase in ovulation rates. A meta-analysis by Zheng et al. (2017) concluded that metformin is effective in improving clinical outcomes related to ovulation and menstrual regularity in PCOS patients.

Moreover, metformin has shown potential in addressing other metabolic disturbances associated with PCOS. It can improve lipid profiles, reduce the risk of type 2 diabetes, and aid in weight management, which are crucial aspects of managing PCOS and reducing long-term health risks.

The Tolerability and Safety of Metformin

Metformin is generally well-tolerated, with gastrointestinal side effects being the most common adverse events. These side effects can often be managed by titrating the dose gradually, taking extended release version, and taking the medication with meals. The risk of lactic acidosis, a rare but serious side effect, is minimal in patients without significant renal impairment.


Metformin offers a multifaceted approach to managing PCOS by addressing both the reproductive and metabolic aspects of the syndrome. Its insulin-sensitizing effects can ameliorate hyperandrogenism and improve ovulatory function, while its metabolic benefits can reduce long-term health risks. While metformin is not a cure for PCOS, it is a valuable tool in the therapeutic arsenal for managing this complex disorder. Further research is warranted to fully elucidate its role in PCOS treatment and to optimize therapeutic strategies.
