Women’s Health
Women’s health, a vital aspect of medical science, encompasses various conditions unique to women’s physiological makeup. Historically, women were often excluded from clinical research, leading to a gap in understanding the intricacies of women’s health needs. However, recent advancements have highlighted the significant role that the microbiome plays in these conditions, offering new insights and potential therapies. MicrobiomeSignatures.com is at the forefront of exploring the microbiome signature of each of these conditions to unravel the etiology of these diseases and develop targeted microbiome therapies.

Polycystic ovary syndrome (PCOS)
Polycystic ovary syndrome (PCOS)
Polycystic ovary syndrome (PCOS) is a common endocrine disorder that affects women of reproductive age, characterized by irregular menstrual cycles, hyperandrogenism, and insulin resistance. It is often associated with metabolic dysfunctions and inflammation, leading to fertility issues and increased risk of type 2 diabetes and cardiovascular disease.

What was reviewed?
This review examines the role of metformin in managing polycystic ovary syndrome (PCOS), specifically focusing on its effectiveness in treating PCOS-related infertility. The paper reviews evidence from randomized controlled trials (RCTs) and other studies, discussing the use of metformin as an insulin-sensitizing agent for women with PCOS who experience anovulatory infertility. It also explores metformin’s impact on metabolic dysfunctions, hyperandrogenism, and its potential use alongside other treatments like clomiphene for improving fertility outcomes in women with PCOS.
Who was reviewed?
The review considers various studies and clinical trials on the use of metformin in women with PCOS. These studies involve women with varying degrees of obesity and insulin resistance, who are experiencing anovulatory infertility, hyperandrogenism, or both. The review synthesizes results from RCTs that examined the effectiveness of metformin alone or in combination with other treatments like clomiphene citrate and aromatase inhibitors in improving ovulation, fertility, and reducing the metabolic disturbances associated with PCOS.
What were the most important findings?
The review highlights several key findings regarding the use of metformin in treating PCOS-related infertility. Metformin has shown efficacy in improving ovulation rates in women with anovulatory infertility, particularly in non-obese women. A Cochrane review of seven RCTs revealed that metformin significantly increased clinical pregnancy rates compared to placebo. However, while metformin showed promise, it did not outperform clomiphene citrate as a first-line treatment for ovulation induction in women with PCOS, particularly in obese patients. The review also found that metformin, when used in combination with clomiphene, can be effective for women who are resistant to clomiphene alone.
Additionally, the review emphasized that metformin has benefits beyond fertility induction. It helps reduce hyperinsulinemia and insulin resistance, which are common in women with PCOS, and can improve associated metabolic conditions such as dyslipidemia and obesity. Furthermore, metformin was found to reduce the risk of ovarian hyperstimulation syndrome (OHSS) in women undergoing in vitro fertilization (IVF). Although metformin’s role in improving long-term health outcomes, such as the prevention of type 2 diabetes, cardiovascular disease, and endometrial cancer, remains inconclusive, it offers significant short-term reproductive benefits.
What are the greatest implications of this review?
The review suggests that metformin should be considered a suitable first-line treatment for non-obese women with anovulatory infertility due to PCOS. For women who are resistant to clomiphene or prefer an alternative to the oral contraceptive pill (OCP) for managing hyperandrogenic symptoms, metformin can be an effective option. Additionally, metformin’s role in reducing the risk of OHSS during IVF procedures underscores its importance in assisted reproductive treatments. The review also raises the need for further research to better define metformin’s long-term benefits in preventing the metabolic and reproductive complications associated with PCOS, as well as its potential to improve long-term health outcomes like diabetes prevention.
