The main limitations were risk of bias and imprecise results. Development of mild anemia with normal mean corpuscular volume MCV values were documented in five patients, all had normal levels of vitamin B For obese women, on the other hand, the pregnancy and live birth rate appeared to be overwhelmingly higher for clomiphene versus metformin 10further supported by a Malaysian RCT 18 in which most of the women were obese and again, clomiphene was found to be superior to metformin for obese women with anovulatory PCOS.

Metformin and polycystic ovary syndrome -

Even greater reductions were achieved with the addition of aggressive lifestyle modifications. The author emphasizes the need for both lifestyle changes and metformin therapy to reduce the risk of diabetes in women with PCOS. Metformin also is effective in achieving weight loss in women with PCOS.

It potentiates the low-calorie diets typically used to achieve the BMI of 20 to 25 kg per m 2 that is necessary for the return of ovulation. In one study of obese women, a 10 percent reduction in BMI was achieved with metformin therapy.

In another study, metformin plus a low-calorie diet was superior to the low-calorie diet alone for weight loss in women with PCOS. The weight loss action of metformin appears to be caused by the reduction in insulin resistance as well as by appetite suppression.

Metformin is the only antidiabetic agent associated with weight loss rather than weight gain and is, thus, particularly suitable for therapy in patients with PCOS. The effects of metformin on menstrual function and infertility may be caused by decreased insulin resistance and lowered testosterone levels.

In a long-term study of 23 women with PCOS, one half of those treated with metformin resumed regular menstruation. The effect appears to increase with duration of treatment. Studies of women who were treated for at least six months report that more than 90 percent of women resumed regular menstruation.

Four to six months of therapy are thought to be necessary for ovulation to commence. The effect of metformin on hirsutism has not been extensively reported, and androgen-blocking drugs may be more effective than metformin for treatment of this symptom.

In studies, about 5 percent of patients discontinued metformin therapy because of side effects, but more than one half of patients reported diarrhea, and one fourth experienced other gastrointestinal upsets.

BM decreased for 3. BMI decreased for 1. Altogether in the first year, patients lost weight, 8 remained the same and 28 patients gained weight.

There was no correlation between body weight change and fasting plasma glucose level or hormonal status level of LH, FSH, DHEAS, androstenedione, total and free testosterone. Patients who lost weight in the first year had significantly less frequent menstrual bleeding at baseline 6.

The two groups did not differ at baseline BM, BMI, fasting plasma glucose level and hormonal status level of LH, FSH, DHEAS, androstenedione, total and free testosterone.

Decrease of BM and BMI remained significant up to visit V 4 when compared with baseline. From V5 up to V10, no significant change in BM was observed when compared with baseline Fig.

Change in body weight A , number of menstrual cycles periods B , total plasma testosterone levels C and plasma androstenedione levels D during the time. Comparisons to pretreatment values were calculated using Wilcoxon test for paired samples.

Menstrual frequency increased from 7. The increase in menstrual frequency was statistically significant from V1—V7 when compared to baseline Fig. We also stratified patients by age and evaluated menstrual frequency in patients younger than 35 years at baseline and patients 35 years old or older at baseline.

In patients younger than 35 years, menstrual frequency increased from 7. Patients in whom menstrual regularity improved after first year had significantly less frequent bleedings 5.

Mean levels of fasting glucose did not change significantly after first year follow-up and not during the following years. The mean values were in the normal range throughout the follow-up Table 1. Patients in whom fasting glucose significantly decreased after first year had significantly higher fasting glucose at baseline 5.

An overall conversion rate to IFG was 6. The highest conversion rate was observed in the first year, when 4 women developed IFG one of them developed T2D in the second year , 2 women developed IGT, 2 women developed IFG and IGT one of them developed T2D in fourth year and one woman developed T2D.

In the second year IFG developed in 2 women, in the third year in one, in fourth year in 2 and in sixth year in one woman. T2D was developed from previously NGT in 2 women in first year, in 1 woman in fourth year and in 2 women in fifth year.

Only in one patient remission from T2D which occurred in second year after developing IFG in first year to IFG was observed in sixth year, but in seventh year T2D reoccurred. Total testosterone and androstenedione decreased for After a decrease in the first year, value of total testosterone remained stable over the treatment period Fig.

In comparison with the women in whom the total testosterone and androstenedione remained unchanged or increased, women in whom total testosterone and androstenedione significantly decreased had higher androstenedione at baseline Women in whom total testosterone significantly decreased after first year were significantly younger Values of LH and FSH decreased slightly over the treatment period, although the difference was not statistically significant yet.

Values of DHEAS did not changed significantly during follow-up period. Table 1. From subjects, the dropout rate was The drop out in this cohort was not associated with metformin intolerance, adverse effects, bariatric surgery or pregnancy since those were the exclusion criteria.

As reported by the patients, the main reason for discontinuation after the third year was the lack of motivation. There were no statistically significant changes in the baseline characteristic between patients that dropped out after third year and the patients who were continuing with the therapy after the third year.

No baseline characteristics were associated with drop out or non-drop out status. They were not included in the study. Although several women that were eligible for the study reported mild-to-moderate nausea and diarrhea at first year of follow-up, the symptoms were transient and disappeared after 4—8 weeks.

No case of lactic acidosis or significant anemia due to vitamin B12 deficiency was documented within the study group during the observational period. Development of mild anemia with normal mean corpuscular volume MCV values were documented in five patients, all had normal levels of vitamin B In majority of women that subsequently remained on therapy, an overall beneficial steady state was observed throughout the follow-up.

Conversion rate to IFG and T2D was low during the observation period, with the highest conversion observed within the first year. Notably, after 2 years, remarkable drop out that had not been related to metformin intolerance or side effects was seen in this real-life setting.

With regard to weight loss, it is often questioned whether long-term treatment with metformin is of benefit above and beyond LSI in overweight-obese patients with PCOS 1 , 6 , 8 , 9 , In our study, mean BM decreased for 3.

A meta-analysis of participants with PCOS treated with metformin for 6 months reported no evidence of its effect on BMI On the other hand, another meta-analysis comparing the effect of metformin with or without LSI to LSI with or without placebo concluded that metformin in combination with LSI was associated with lower BMI 6 , 16 , Also, in concordance with our observation, metformin added to LSI offered success in sustainability of weight reduction over 4 years in prospective cohort of 74 PCOS women 19 , whereas LSI alone is in general not very successful in preventing body weight regain after initial weight loss 20 , 21 , 22 , 23 , Given that PCOS is characterized by progressive weight gain from menarche 25 , 26 , 27 , the difficulty in stabilization of BM is expected to be even more pronounced in PCOS when compared to general population.

Potential goal of long-term treatment with metformin in overweight-obese women with PCOS should therefore be a stabilization of BM through the years rather than weight reduction itself.

The amount of weight loss in our study correlated with the initial body weight and baseline number of menstrual bleedings per year.

Women who lost weight in the first year had higher BM and less frequent menstrual bleeding at baseline.

Greater capacity to lose weight in patients with higher BMI than in patients with slighter obesity was confirmed also in another real-life setting investigated metformin use in PCOS This finding may be explained by the lower levels of testosterone in women older than 35 years, which may reduce the strength of the association between the two parameters.

The data on the relationship between adiposity and total testosterone in PCOS from other studies are scarce and controversial Metformin use in PCOS is not consistently associated with improvements in menstrual regularity. In a Cohrane review that included a meta-analysis of 38 RCT of women with PCOS, metformin therapy only marginally improved menstrual pattern In our cohort menstrual frequency increased after first year and normalized in the majority of patients in the following years.

In the month study conducted with prospective cohort, metformin was also associated with improvements in the menstrual cycle in overweight and normal weight women with PCOS Our patients in whom menstrual regularity improved after first year had less frequent bleedings at baseline when compared with those with no improvement in menstrual frequencies.

Importantly, the potential effect of aging that results in improvement of hyperandogenism as well as the well-known methodological difficulties related to RIA assays should be taken into account when interpreting the observed impact on the androgen status.

In comparison with the women in whom androgens remained unchanged or increased, women in whom androgens decreased had worst androgen profile at baseline. It is believed that metformin lowered testosterone levels by reducing hyperinsulinemia 32 , In addition, it might have a direct inhibitory effect on ovarian steroidogenesis 34 , 35 , 36 through inhibition of mitochondrial complex I Given that an androgen excess plays an important role in favoring the expansion of visceral fat and development of metabolic syndrome and T2D 37 , the improved androgen profile observed throughout long-term metformin treatment should be considered as an independent cardiometabolic risk reduction outcome in these population.

Few studies aimed to clarify the relationship between PCOS and T2D independent of obesity in longitudinal population-based cohorts. There have been very limited studies of the natural history of glucose homeostasis in this population. In an elegant study by Legro et al. Prospective studies investigating the impact of metformin on T2D risk specifically in women with PCOS are lacking 6.

Nonetheless, considering that these women are at high risk for developing T2D 39 , 40 , it has been suggested that they will benefit from metformin therapy in case of glucose intolerance 7. One of the longest retrospective study with 50 patients followed by a mean treatment period of In our cohort the mean fasting glucose was within normal range throughout the longitudinal follow-up.

Conversion to IGT and T2D was low, yet OGTT was not performed annually, but as recommended by national guidelines rescreened periodically at 2—3 years, meaning that this conversion risk could be underestimated.

We acknowledge that our study has several limitations. The major one is its retrospective nature. It is clear that prospective randomized design represents the gold standard, but such a study would be extremely long lasting and laborious to achieve.

Lack of randomization with placebo represents another possible bias, yet placebo arm in this group would have hardly been a realistic or possible approach. Moreover, the possible bias might be related to the process of ageing, in particular when interpreting the improvements of menstrual irregularity and hyperandrogenism as both improve by age.

Furthermore, lifestyle measures that had been promoted by the lifestyle advice might contribute to at least some of the benefits including low rates of conversion to IGT and T2DM.

Another point of concern is the high rate of drop-outs and the effects that may have on the study outcome. However, this attrition rate was similar to that from other studies on PCOS 16 , The main strength of this study is the long-term longitudinal follow-up assessing the effectiveness of treatment with metformin in real life setting that is insufficiently studied in PCOS.

Attempts were made to achieve clinical homogeneity of the included patients by reviewing the medical records of all patients that had been referred to our clinics from to All patients were managed in the single center using a standardized treatment protocol with mg metformin that had been introduced in all overweight-obese women regardless of their glycemic status unless contraindicated since , and thus any possible selection bias had been eliminated.

This offers very important and rarely available insight into the long-term longitudinal follow-up in this subset of patients that have not been, in general, characterized as candidates for metformin treatment until the latest recommendations update 7. We conclude that, in agreement with the latest recommendations 7 , metformin should not be withheld from treatment of PCOS in overweight-obese women with normal fasting glucose and normal glucose tolerance.

We suggest that treatment decisions for metformin are based on BMI, oligomenorrhea and biochemical hyperandrogenism regardless of the glycemic status. The overweight-obese and oligomenorrheic women should be prioritized treatment candidates.

The high rate of drop outs not related to intolerance and side effects could be decreased in clinical practice by discussing the realistic treatment goals and potential benefits of long-term intervention. We encourage future designs to investigate the stabilization of BM through the years as one of the main treatment benefits of long-term treatment with metformin in overweight-obese PCOS.

The separate impact of metformin on visceral and s. fat depots is another topic that deserves further attention. The protective effect of the long-term use of metformin in reducing the risk of unopposed endometrial proliferation and endometrium cancer should also be evaluated.

The next important question is for how long metformin should be applied to reach the homeostasis that can sustain weight and glucose metabolism after metformin withdrawal. We suggest to compare the consequences of metformin withdrawal after long-term therapy as opposed to the consequences of metformin withdrawal immediately after the maximum treatment effect is achieved, usually after the first year.

Intermittent regimens vs continuing long-term interventions with metformin represent another issue to be addressed. The heterogeneity in response to metformin represents another exciting research field.

Traditional as well as nontraditional risk cardiometabolic markers including chronic inflammation, oxidative stress, homeostasis and fibrinolysis imbalance, gut microbiota dysbiosis and epigenetic alterations sympathetic nervous system dysfunction 41 should be considered as potential predictors for responders and non-responders.

Furthermore, large-scale genome wide studies are also imperative to identify the best responders. The further research needs to firstly identify and then prioritize those groups who will benefit most from being treated with metformin.

The treatment goals and duration of therapy should be clearly defined, in particular, in overweight-obese women with PCOS and normal initial glucose homeostasis where its long-term use is currently more difficult to advocate. Individually tailored approaches might lead to better adherence that would provide better insights into a long-term cost—benefit profile.

Continuing follow-ups in randomized prospective trials and in real life settings would provide further information on putative long-term benefits of metformin and whether they are homogeneous across subgroups. The authors declare that there is no conflict of interest that could be perceived as prejudicing the impartiality of the research reported.
