Abstract
BACKGROUND Polycystic ovary syndrome (PCOS) is the most common cause of anovulatory infertility. Obesity exacerbates the reproductive complications of PCOS; however, the management of obesity in women with PCOS remains a large unmet clinical need. Observational studies have indicated that bariatric surgery could improve the rates of ovulatory cycles and prospects of fertility; however, the efficacy of surgery on ovulation rates has not yet been compared with behavioural modifications and medical therapy in a randomised trial. The aim of this study was to compare the safety and efficacy of bariatric surgery versus medical care on ovulation rates in women with PCOS, obesity, and oligomenorrhoea or amenorrhoea. METHODS In this multicentre, open-label, randomised controlled trial, 80 women older than 18 years, with a diagnosis of PCOS based on the 2018 international evidence-based guidelines for assessing and managing PCOS, and a BMI of 35 kg/m2 or higher, were recruited from two specialist obesity management centres and via social media. Participants were randomly assigned at a 1:1 ratio to either vertical sleeve gastrectomy or behavioural interventions and medical therapy using a computer-generated random sequence (PLAN procedure in SAS) by an independent researcher not involved with any other aspect of the clinical trial. The median age of the entire cohort was 31 years and 79% of participants were White. The primary outcome was the number of biochemically confirmed ovulatory events over 52 weeks, and was assessed using weekly serum progesterone measurements. The primary endpoint included the intention-to-treat population and safety analyses were per-protocol population. This study is registered with the ISRCTN registry (ISRCTN16668711). FINDINGS Participants were recruited from Feb 20, 2020 to Feb 1, 2021. 40 participants were assigned to each group and there were seven dropouts in the medical group and ten dropouts in the surgical group. The median number of ovulations was 6 (IQR 3·5-10·0) in the surgical group and 2 (0·0-4·0) in the medical group. Women in the surgical group had 2.5 times more spontaneous ovulations compared with the medical group (incidence rate ratio 2·5 [95% CI 1·5-4·2], p<0·0007). There were more complications in the surgical group than the medical group, although without long-term sequelae. There were 24 (66·7%) adverse events in the surgical group and 12 (30·0%) in the medical group. There were no treatment-related deaths. INTERPRETATION Bariatric surgery was more effective than medical care for the induction of spontaneous ovulation in women with PCOS, obesity, and oligomenorrhoea or amenorrhoea. Bariatric surgery could, therefore, enhance the prospects of spontaneous fertility in this group of women. FUNDING The Jon Moulton Charity Trust.

Abstract
BACKGROUND Polycystic ovary syndrome (PCOS) is the most common reproductive endocrine disorder in women of reproductive age. It is difficult for patients with PCOS to achieve weight loss with conventional treatment. The aim of this study was to investigate weight loss and changes in hypothalamic-pituitary axis hormone levels in patients with PCOS combined with obesity after sleeve gastrectomy. METHODS A retrospective analysis of 12 patients without PCOS and 24 patients with PCOS who underwent bariatric surgery at Beijing Luhe hospital from 2020 to 2022 was performed. The study assessed the changes in body weight and hormonal indexes of the hypothalamic-pituitary axis before and six months after the surgery. RESULTS Patients with PCOS experienced greater weight loss compared to those without the condition. Following surgery, individuals with PCOS showed lower levels of postoperative testosterone, prolactin, and free testosterone indices compared to preoperative levels. Additionally, postoperative LH and FSH levels were higher than preoperative levels. Analysis of thyroid axis hormone levels revealed that FT3 and TSH levels were notably reduced in patients with PCOS postoperatively. Furthermore, growth hormone levels were found to be elevated in patients with PCOS following surgery. CONCLUSION Bariatric surgery enhances hormone levels in the hypothalamic-pituitary axis in women with PCOS, leading to greater improvements in patients with PCOS compared to those with simple obesity.

Impact of bariatric surgery on anthropometric, metabolic, and reproductive outcomes in polycystic ovary syndrome: a systematic review and meta-analysis. Obes Rev 2024; 25:e13737.

Abstract
Polycystic ovary syndrome (PCOS) is a common endocrine disorder in females. Modest weight loss improves reproductive and metabolic PCOS features. While lifestyle modifications and pharmacotherapies remain first-line weight loss strategies, bariatric surgery is emerging as a potentially effective treatment. We performed a systematic review and meta-analysis of published literature to examine the impact of bariatric surgery in PCOS to inform the 2023 International PCOS Evidence-based Guidelines. Electronic databases were searched for observational studies and trials comparing pharmacologic or lifestyle treatments to bariatric surgery in women with PCOS or bariatric surgery in women with or without PCOS. Anthropometric, reproductive, hormonal, and metabolic outcomes were included and, where possible, meta-analyzed using random-effects models. Risk of bias and evidence quality were assessed. Ten studies were included involving 432 women with and 590 women without PCOS. Comparisons between bariatric surgery and pharmacologic or lifestyle treatments were only reported in one study each, and most reproductive outcomes were limited to a single study; therefore, meta-analyses could not be performed. Meta-analysis found that women with PCOS experience similar improvements in anthropometric, hormonal, and metabolic outcomes after bariatric surgery compared to those without PCOS. Existing research is limited and of low quality with high risk of bias, especially in comparison to existing PCOS treatments and with respect to reproductive outcomes including pregnancy, highlighting the need for additional studies to inform clinical recommendations.

[PMID: 38529391 PMCID: PMC10961366 DOI: 10.3389/fendo.2024.1355703] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/14/2023] [Accepted: 02/22/2024] [Indexed: 03/27/2024] Open
Abstract
Introduction Polycystic ovary syndrome (PCOS) is the most common endocrinopathy affecting reproductive-aged women. Some retrospective studies with small sample sizes have reported that bariatric metabolic surgery is effective in remission of irregular menstruation in patients with PCOS and obesity. However, the correlation between preoperative body mass index (BMI), postoperative weight loss, and remission of irregular menstruation in patients with obesity and PCOS after sleeve gastrectomy (SG) is lack of consensus. Methods We enrolled 229 participants with obesity and PCOS who underwent SG. All patients were followed up for one year after surgery. Remission of irregular menstruation was defined as a spontaneous consecutive six-month menstrual cycle in one year. Subgroup analysis was conducted using tertiles of preoperative BMI and postoperative total weight loss (TWL)% to determine their correlation with the remission of irregular menstruation after SG. Results 79.03% (181/229) patients achieved remission of irregular menstruation one year after SG with a TWL% of 33.25 ± 0.46%. No significant difference was detected in the remission rate among the subgroups with different BMI (P=0.908). TWL% was correlated with the remission of irregular menstruation (OR 1.78, 95% CI 1.18-2.69, P<0.05). Conclusions SG had a significant effect on the remission of irregular menstruation in patients with obesity and PCOS. Preoperative BMI did not emerge as a decisive factor correlated with remission; instead, TWL% showed potential as a key factor.

Abstract
Polycystic ovary syndrome (PCOS) is the most common endocrine condition in premenopausal women and is a common cause of anovulatory subfertility. Although obesity does not form part of the diagnostic criteria, it affects a significant proportion of women with PCOS and is strongly implicated in the pathophysiology of the disease. Both PCOS and obesity are known to impact fertility in women; obesity also reduces the success of assisted reproductive technology (ART). With or without pharmacotherapy, lifestyle intervention remains the first-line treatment in women with PCOS and obesity. Bariatric surgery is still an experimental treatment in women with PCOS and subfertility. This review will present an overview of the pathophysiology of PCOS and obesity and the role of bariatric surgery. Although data are sparse regarding the impact of bariatric surgery on subfertility in women with PCOS and obesity, existing studies point to a beneficial role in treating metabolic and reproductive dysfunction.

Abstract
PURPOSE This study aimed to evaluate the efficacy of sleeve gastrectomy (SG) on patients with obesity and polycystic ovary syndrome (PCOS). MATERIALS AND METHODS We searched PubMed, Embase, Cochrane Library, and Web of Science to identify relevant studies published prior to December 2, 2022. Meta-analysis was performed on menstrual irregularity, total testosterone, sex hormone-binding globulin (SHBG), anti-Mullerian hormone (AMH), glucolipid metabolism indicators, and body mass index (BMI) following SG. RESULTS Six studies and 218 patients were included in the meta-analysis. Following SG, menstrual irregularity significantly decreased (odds ratio [OR] 0.03; 95% confidence intervals [CIs], 0.00-0.24; P=0.001). Additionally, SG can lower total testosterone levels (MD -0.73; 95% CIs -0.86-0.60; P< 0.0001), as well as BMI (MD -11.59; 95% CIs -13.10-10.08; P<0.0001). A significant increase was observed in the levels of SHBG and high-density lipoprotein (HDL) after SG. In addition to reducing fasting blood glucose, insulin, triglycerides (TG), and low-density lipoprotein levels, SG significantly reduced low-density lipoprotein levels as well. CONCLUSIONS Following SG, we firstly demonstrated significant improvements in menstrual irregularity, testosterone and SHGB levels, glycolipid metabolism indicators, and BMI. Therefore, SG may be considered as a new option for the clinical treatment of patients with obesity and PCOS.

Metabolic shift precedes the resolution of inflammation in a cohort of patients undergoing bariatric and metabolic surgery. Sci Rep 2021; 11:12127. [PMID: 34108550 PMCID: PMC8190106 DOI: 10.1038/s41598-021-91393-y] [Citation(s) in RCA: 24] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2020] [Accepted: 05/20/2021] [Indexed: 12/13/2022] Open
Abstract
Bariatric and metabolic surgery has shown to promote weight loss and reduce systemic inflammation. However, the sequence and timing of events regarding metabolic improvement and inflammation resolution has been rarely explored. Furthermore, data on inflammatory markers of Th17 and Th1 cell responses after bariatric surgery is scarce. We conducted a prospective study in subjects with obesity that underwent bariatric and metabolic surgery, with follow-ups at 3 and 6 months. Anthropometric and metabolic markers such as insulin levels, HOMA-IR, and lipid parameters declined significantly 3 months after surgery; while hs-CRP, TNF-α, IL-1β, IL-6, and IL-8 serum concentrations decreased 6 months after the procedure. Concentrations of Th1 signature and driver cytokines, particularly IFN-γ, IL-12, and IL-18, and of Th17 driver IL-23 also decreased significantly after 6 months. Significant positive correlations between triglyceride levels and hs-CRP, IL-1β, and IFN-γ concentrations, and between Apo B and IFN-γ levels were observed 6 months after bariatric and metabolic surgery. In addition, BMI was associated with hs-CRP and TNF-α concentrations. Fat mass correlated with hs-CRP, TNF-α, and IL-12. Analysis of the temporality of metabolic and inflammatory events suggests that improvement in the metabolic status occurs before resolution of systemic inflammation and may be a requisite for the later event.

Abstract
BACKGROUND Bariatric surgery is effective for polycystic ovary syndrome (PCOS), while the exact mechanism remains unclear. OBJECTIVES To assess the impact of bariatric surgery on PCOS patients and further explore the possible mechanism. SETTING A meta-analysis. METHODS We searched PubMed, Web of Science, The Cochrane Library, and Embase to identify relevant studies published before November 2020. RESULTS Twenty-one studies met our inclusion criteria, and we identified 552 patients with PCOS study. Results showed that the prevalence of preoperative PCOS, menstrual irregularity, hirsutism, type 2 diabetes (T2D), hypertension, infertility, and depression significantly decreased after bariatric surgery. Levels of total testosterone, fasting insulin, and luteinizing hormone (LH) decreased and estradiol increased, while levels of follicle-stimulating hormone (FSH) and LH/FSH did not show significant changes during the 3-month follow-up. There were decreases in testosterone and fasting insulin levels when the postoperative follow-up time was 6 months or ≥12 months. Levels of fasting blood glucose and triglycerides were significantly reduced after 6 months or ≥12 months of bariatric surgery. High-density lipoprotein (HDL) and sex hormone-binding globulin (SHBG) significantly improved ≥12 months after bariatric surgery. CONCLUSION Symptoms of PCOS and related complications are significantly alleviated after bariatric surgery. In addition, we found a significant improvement on anomalous secretion of gonadotropins, glucose metabolism, and lipid metabolism in patients with PCOS after bariatric surgery.

Abstract
Although the current literature associates polycystic ovarian syndrome (PCOS) with chronic inflammation, the evidence for this link remains inconclusive and its causal nature remains unclear. The purpose of this systematic review was to assess the inflammatory status in PCOS women and to determine whether it is related to PCOS or to its associated adiposity. We searched electronic databases including PUBMED, EMBASE and MEDLINE, SCOPUS, DynaMed plus, TRIP, ScienceDirect and Cochrane Library, for studies investigating C-reactive protein (CRP) and other inflammatory makers in PCOS women versus healthy controls. Quality and risk of bias for selected studies were assessed using the modified Newcastle-Ottawa scale. CRP data were extracted and pooled using RevMan for calculation of the standardized mean difference (SMD) and 95% confidence interval (CI). Eighty-five eligible studies were included in the systematic review, of which 63 were included in the meta-analysis. Pooled analysis of the 63 studies revealed significantly higher circulating CRP in PCOS women (n = 4086) versus controls (n = 3120) (SMD 1.26, 95%CI, 0.99, 1.53). Sensitivity meta-analysis of 35 high quality studies including non-obese women showed significantly higher circulating CRP in PCOS women versus controls (SMD 1.80, 95%CI, 1.36, 2.25). In conclusion, circulating CRP is moderately elevated in PCOS women independent of obesity, which is indicative of low-grade chronic inflammation.

Abstract
IMPORTANCE Obesity is associated with a number of noncommunicable chronic diseases and is purported to cause premature death. OBJECTIVE To summarize evidence on the temporality of the association between higher body mass index (BMI) and 2 potential mediators: chronic inflammation and hyperinsulinemia. DATA SOURCES MEDLINE (1946 to August 20, 2019) and Embase (from 1974 to August 19, 2019) were searched, although only studies published in 2018 were included because of a high volume of results. The data analysis was conducted between January 2020 and October 2020. STUDY SELECTION AND MEASURES Longitudinal studies and randomized clinical trials that measured fasting insulin level and/or an inflammation marker and BMI with at least 3 commensurate time points were selected. DATA EXTRACTION AND SYNTHESIS Slopes of these markers were calculated between time points and standardized. Standardized slopes were meta-regressed in later periods (period 2) with standardized slopes in earlier periods (period 1). Evidence-based items potentially indicating risk of bias were assessed. RESULTS Of 1865 records, 60 eligible studies with 112 cohorts of 5603 participants were identified. Most standardized slopes were negative, meaning that participants in most studies experienced decreases in BMI, fasting insulin level, and C-reactive protein level. The association between period 1 fasting insulin level and period 2 BMI was positive and significant (β = 0.26; 95% CI, 0.13-0.38; I2 = 79%): for every unit of SD change in period 1 insulin level, there was an ensuing associated change in 0.26 units of SD in period 2 BMI. The association of period 1 fasting insulin level with period 2 BMI remained significant when period 1 C-reactive protein level was added to the model (β = 0.57; 95% CI, 0.27-0.86). In this bivariable model, period 1 C-reactive protein level was not significantly associated with period 2 BMI (β = -0.07; 95% CI, -0.42 to 0.29; I2 = 81%). CONCLUSIONS AND RELEVANCE In this meta-analysis, the finding of temporal sequencing (in which changes in fasting insulin level precede changes in weight) is not consistent with the assertion that obesity causes noncommunicable chronic diseases and premature death by increasing levels of fasting insulin.

Abstract
The pathophysiology of Polycystic Ovary Syndrome (PCOS) is quite complex and different mechanisms could contribute to hyperandrogenism and anovulation, which are the main features of the syndrome. Obesity and insulin-resistance are claimed as the principal factors contributing to the clinical presentation; in normal weight PCOS either, increased visceral adipose tissue has been described. However, their role is still debated, as debated are the biochemical markers linked to obesity per se. Oxidative stress (OS) and low-grade inflammation (LGI) have recently been a matter of researcher attention; they can influence each other in a reciprocal vicious cycle. In this review, we summarize the main mechanism of radical generation and the link with LGI. Furthermore, we discuss papers in favor or against the role of obesity as the first pathogenetic factor, and show how OS itself, on the contrary, can induce obesity and insulin resistance; in particular, the role of GH-IGF-1 axis is highlighted. Finally, the possible consequences on vitamin D synthesis and activation on the immune system are briefly discussed. This review intends to underline the key role of oxidative stress and low-grade inflammation in the physiopathology of PCOS, they can cause or worsen obesity, insulin-resistance, vitamin D deficiency, and immune dyscrasia, suggesting an inverse interaction to what is usually considered.

Abstract
Polycystic ovarian syndrome (PCOS) is the most common endocrine disorder in reproductive-age women that causes infertility. Obesity and insulin resistance are closely tied to the pathophysiology of PCOS. Current first-line treatments include lifestyle modifications, hormone modulators, and laparoscopic ovarian drilling, but little attention has been given to bariatric surgery as a viable option. A detailed review of the literature regarding the outcomes of obese women with PCOS after bariatric surgery is necessary. All studies were found in the PubMed database, limited to females and humans, and selected due to relevancy and quantitative data. Bariatric surgery promotes significant weight loss within one year, which is associated with amelioration of insulin resistance, hyperandrogenism, menstrual irregularity, and ovulatory dysfunction. Surgery successfully mediates the regression of PCOS and promotes successful pregnancy. Thus, we recommend the consideration of bariatric surgery as part of the main treatment considerations in obese patients with PCOS. However, more focused and comprehensive research with better study designs are still needed in the future to investigate PCOS and bariatric surgery.

Abstract
Background: Obesity is one of the most common risk factors for polycystic ovarian syndrome (PCOS). Reducing body weight has shown to improve the symptoms of PCOS; however, it is still unclear if the surgical treatment of obesity can have better outcomes to control obesity and improve PCOS. Objective: This study aims to identify the impact of sleeve gastrectomy on PCOS symptoms in Riyadh, Saudi Arabia with a comparison of other weight reduction surgeries. Design and Setting: This is a prospective study that included patients with PCOS who had weight reduction surgeries between 2018 and 2020, in Riyadh, Saudi Arabia. Using an online questionnaire, demographic data will be collected and information about menstruation, abortion, polycystic ovarian syndrome, and bariatric surgeries (if any). Data analysis was done through Statistical Package for the Social Sciences (SPSS) v26 (IBM Corp., Armonk, NY, USA). Results: Ninety-nine female patients responded to this survey, all of whom had PCOS; 57.6% of these patients had a positive family history of PCOS. The most-reported PCOS symptoms were irregular menses (63.6%) and weight gain (53.5%), while 9.1% were asymptomatic. 52.5% were obese, and 91.1% underwent gastric sleeve surgery to treat their obesity. 41.4% of the females had a regular cycle before the operation, which increased to 60.6% after the operation; 48.5% had a normal flow before the operation, which increased to 61.6% after the operation. 15.2% conceived once before the operation, which increased to 16.2% after the operation. 11.1% had one abortion before surgery, which decreased to 7.1% after surgery. 55.6% observed an improvement in their PCOS symptoms after surgery, and 47.5% found that their fertility improved according to their own perception. Females with a positive family history of PCOS had a higher prevalence of PCOS (p-value <0.001). Also, females 30-39 years old are significantly more likely to have PCOS (p-value <0.001). The incidence of abnormal menstrual flow and irregular menstrual cycle was seen significantly more in PCOS patients than non-PCOS (p-value=0.019 and 0.004, respectively). PCOS symptoms and fertility significantly improved after surgery (p-value=0.031 and 0.043, respectively). Conclusion: Sleeve gastrectomy can lead to significant improvement in fertility and symptoms of PCOS. It can also reduce the incidence of abortion. Other surgical techniques should be investigated.

Abstract
OBJECTIVES The purpose of this study was to determine changes in the expression levels of kisspeptin-1 (Kiss1) in the hypothalamus during the development of polycystic ovary syndrome (PCOS) and after treatment with sleeve gastrectomy (SG). METHODS This study used chronic dehydroepiandrosterone (DHEA) alone and DHEA plus a high-fat diet (HFD) to generate a PCOS rat model. Subsequently, SG was performed in the animals with PCOS and the effects on glucose tolerance, insulin sensitivity, sex hormones, estrous cyclicity, adiponectin, and Kiss1 expression in the hypothalamus were investigated. RESULTS Impaired glucose tolerance, decreased insulin sensitivity, reduced adiponectin levels, disrupted estrous cyclicity, and elevated sex hormone levels associated with PCOS models were restored to normal following SG. In addition, SG was able to restore the increase in the expression of Kiss1 mRNA and Kiss1-positive neurons in the arcuate nucleus of rats with PCOS. Interestingly, although SG did not result in a significant loss of body weight in rats administered DHEA under a chow diet, it resulted in comparable metabolic improvements and Kiss1 expression in rats that had been administered DHEA along with an HFD. CONCLUSIONS The recovery of normal levels of Kiss1 expression in the hypothalamus after SG in this study suggests that Kiss1 might play an important role in the development of PCOS and its improvement by SG.

Abstract
This systematic literature review aims to point out sex-specific special features that are important in the bariatric treatment of women suffering from severe obesity. A systematic literature search was carried out according to Cochrane and Preferred Reporting Items for Systematic review and Meta-Analysis Protocols (PRISMA-P) guidelines. After the literature selection, the following categories were determined: sexuality and sexual function; contraception; fertility; sex hormones and polycystic ovary syndrome; menopause and osteoporosis; pregnancy and breastfeeding; pelvic floor disorders and urinary incontinence; female-specific cancer; and metabolism, outcome, and quality of life. For each category, the current status of research is illuminated and implications for bariatric treatment are determined. A summary that includes key messages is given for each subsection. An overall result of this paper is an understanding that sex-specific risks that follow or result from bariatric surgery should be considered more in aftercare. In order to increase the evidence, further research focusing on sex-specific differences in the outcome of bariatric surgery and promising treatment approaches to female-specific diseases is needed. Nevertheless, bariatric surgery shows good potential in the treatment of sex-specific aspects for severely obese women that goes far beyond mere weight loss and reduction of metabolic risks.

Abstract
Polycystic ovary syndrome (PCOS) has multiple etiologies including ovarian and adrenal hyperandrogenism, neuro-endocrine and hypothalamic-pituitary dysfunction, and disorders of peripheral insulin resistance. Obesity is neither necessary nor sufficient for the PCOS phenotype, and the association of PCOS with obesity is not universal, with national, cultural, and ethnic differences. Obesity, particularly visceral adiposity which is common in obese and non-obese women with PCOS, amplifies and worsens all metabolic and reproductive outcomes in PCOS. Obesity increases insulin resistance and compensatory hyperinsulinemia, which in turn increases adipogenesis and decreases lipolysis. Obesity sensitizes thecal cells to LH stimulation and amplifies functional ovarian hyperandrogenism by upregulating ovarian androgen production. Obesity increases inflammatory adipokines which, in turn, increase insulin resistance and adipogenesis. Lifestyle interventions focused on diet-weight loss and concurrent exercise are central to therapy which also commonly subsequently needs to include pharmacologic therapy. PCOS symptoms commonly improve with 5% to 10% weight loss, but 25% to 50% weight loss, usually achievable only through bariatric surgery, may be required for morbid obesity unresponsive to lifestyle-medical treatment. Bariatric surgery is a valuable approach to weight loss in PCOS where BMI is ≥40 kg/m2 when non-surgical treatment and/or induction of pregnancy have failed, and can be an initial treatment when BMI is ≥50 kg/m2. Further research in PCOS is needed to better understand the fundamental basis of the disorder, to ameliorate obesity, to correct hyperandrogenism, ovulation, hyperinsulinemia, and to optimize metabolic homeostasis.
