Abstract
Introduction A reduction in anti-müllerian hormone (AMH) levels at short-term after bariatric surgery (BS) has been previously described. However, an assessment of ovarian reserve at longer-follow up, and a comprehensive evaluation of the potentially implicated factors has not been reported. Design Prospective cohort study. Materials and methods Twenty women aged 18-40 years with BMI 43.95 kg/m2 undergoing BS were studied at baseline (BS0), and at 1 month (BS1), 4 months (BS2), 12 months (BS3), and 24-36 months (BS4) after the surgery. Anthropometrics, reproductive hormones (AMH, FSH, LH, estradiol, testosterone, SHBG, androstenedione), metabolic parameters (adiponectin, leptin, ghrelin, insulin), and nutritional blood parameters (markers of nutritional status, vitamins, and minerals) were obtained at each study time point. Antral follicular count (AFC) was assessed by ultrasonography at BS0, BS3, and BS4. Mixed models were used for analysis of longitudinal data. Results The mean AMH level was 3.88 ng/mL at BS0, decreased at BS3 (mean= 2.59 ng/mL; p=0.009), and remained stable between BS3 and BS4 (mean= 2.96 ng/mL; p=0.409). We also observed a non-significant decrease in AFC at BS3 (mean=26.14 at BS0, mean 16.81 at BS3; p=0.088) that remained stable at BS4 (mean= 17.86; p=0.731). Mixed models analysis showed: (a) a decrease in 10 kg of body weight was associated with an average decrease of 0.357 ng/mL in AMH (p=0.014); (b) a decrease in 1 BMI point was associated with an average decrease of 0.109 ng/mL in AMH (p=0.005); (c) an increase in 1 µg/mL of adiponectin was associated with an average decrease of 0.091 ng/ml in AMH (p=0.041) Significant positive correlations were found between the AMH levels after BS and plasma concentrations of testosterone, free androgen index, insulin and HOMA index. No significant correlations were detected between AMH levels and nutritional parameters. Conclusions Our results were in line with previous observations, showing that AMH levels decreased significantly at 12 months after bariatric surgery, in parallel with a non-significant reduction in AFC. Both ovarian reserve markers showed a later stabilization up to the end of the study. Of note, postoperative AMH levels were positively correlated with key androgen and insulin resistance-related parameters.

Abstract
STUDY QUESTION Does previous bariatric surgery (BS) in women affect cumulative live birth rate in IVF? SUMMARY ANSWER Women having had BS seem to have the same cumulative live birth rate as non-operated women of the same BMI at IVF treatment. WHAT IS KNOWN ALREADY Because of the perinatal risks of obesity to mother and infant as well as impaired outcomes of IVF, obese women are advised to reduce their weight, but it is not clear whether previous BS could affect IVF results. STUDY DESIGN, SIZE, DURATION This national register-based case–control study included all cases of BS (n = 30 436) undergoing IVF (n = 153) from 2007 until 2017. PARTICIPANTS/MATERIALS, SETTING, METHODS Swedish women between 18 and 45 years operated with BS, with at least one first started cycle of IVF after surgery, were included. For each woman having IVF after BS (n = 153), up to five non-operated control women (n = 744) starting their first IVF cycle during the study period were matched for age, parity and BMI at treatment. The primary outcome in this study was the cumulative live birth rate (CLBR) after the first IVF cycle, defined as all live births after the first cycle including fresh and frozen embryo transfers. MAIN RESULTS AND THE ROLE OF CHANCE There was no significant difference in CLBR between the BS group and the matched controls (29.4% compared to 33.1%), even though the number of retrieved oocytes (7.6 vs 8.9, P = 0.005) and frozen embryos (1.0 vs 1.5, P = 0.041) were significantly fewer in the BS group. There was no association between cumulative live birth and BS, adjusted odds ratio 1.04, 95% CI (0.73, 1.51). However, the birth weight was significantly lower in the children born to mothers with previous BS, mean (SD) 3190 (690) vs 3478 (729) g, P = 0.037. LIMITATIONS, REASONS FOR CAUTION Confounders such as age, BMI and previous childbirth were accounted for by the matching design of the study, but there were no data on indication for IVF, anti-Müllerian hormone, smoking or previous comorbidities. The study was exploratory and did not reach sufficient power to detect potential smaller differences in live birth rates. WIDER IMPLICATIONS OF THE FINDINGS The findings concur with those in previously published smaller studies and provide somewhat reassuring results considering IVF outcomes after BS with a CLBR comparable to that of controls, despite a lower mean birth weight. STUDY FUNDING/COMPETING INTEREST(S) This research was funded by grants from the Southern Health Care Region of Sweden. The authors have no competing interests to declare. TRIAL REGISTRATION NUMBER N/A.

Abstract
OBJECTIVE Anti-Müllerian hormone (AMH) is recognized as the most important biomarker for ovarian reserve. In this cross-sectional study, we aimed to explore the potential association of AMH with central obesity or general obesity in women with polycystic ovary syndrome (PCOS). METHODS In this cross-sectional study, 179 patients with PCOS were enrolled and underwent anthropometric measurements (BMI and waist circumference (WC)) and serum AMH level detection. Pearson's correlation and multivariable logistic regression analyses were performed to determine the associations of AMH with central obesity and general obesity. RESULTS Subjects with increasing BMI showed significantly lower values of AMH (median (interquartile range (IQR)) 8.95 (6.03-13.60) ng/mL in normal weight group, 6.57 (4.18-8.77) ng/mL in overweight group, and 6.03 (4.34-9.44) ng/mL in obesity group, P = 0.001), but higher levels of systolic blood pressure, fasting insulin, total cholesterol, triglycerides, LDL-c, obesity indices (WC, hip circumferences, waist-to-hip ratio, waist-to-height ratio (WHtR), and Chinese visceral adiposity index (CVAI)). Compared with the group of PCOS women without central obesity, the group with central obesity had significantly lower value of AMH (median (IQR) 8.56 (5.29-12.96) ng/mL vs 6.22 (4.33-8.82) ng/mL; P = 0.003). Pearson's correlation analysis showed that AMH was significantly and negatively correlated with BMI (r = -0.280; P < 0.001), WC (r = -0.263; P < 0.001), WHtR (r = -0.273; P < 0.001), and CVAI (r = -0.211; P = 0.006). Multivariate logistic regression analysis with adjustment for potential confounding factors showed that AMH was independently and negatively associated with central obesity but was not significantly associated with general obesity. CONCLUSIONS AMH was independently and negatively associated with central obesity. Closely monitoring the WC and AMH should be addressed in terms of assessing ovarian reserve in women with PCOS.

Abstract
The presence of obesity may significantly influence female fertility through various mechanisms. Impairment of the hypothalamic-pituitary-ovarian axis in obese women may induce anovulation and infertility. Obesity may have an effect on women’s spontaneous and assisted conception rates, increased miscarriage rates, premature labor, stillbirth and perinatal risks, and menstrual irregularity. It has been suggested that weight loss improves reproductive outcomes due to fertility amelioration and an improvement in menstrual irregularity and ovulation. It is still not known which weight reduction procedures (changes in lifestyle, pharmacological management or bariatric intervention) result in optimal outcome on infertility. Currently, bariatric surgery is defined as the best available method for the management of obesity and its associated diseases. We have analyzed literature facts about effects of bariatric surgery on the function of the hypothalamic-pituitary-ovarian axis, polycystic ovary syndrome (PCOS), anti-Mullerian hormone (AMH) and sexual dysfunction in obesity and pregnancy in obesity. Immediate positive effects of bariatric surgery are evident at the moment, while for long-term outcomes more prolonged follow-up investigations should be done.

Abstract
PURPOSE Bariatric surgery is very efficacious in treating severe obesity. However, its effect on menstruation and ovulation is currently unknown. The purpose of this study was to assess the effect of gastric sleeve resection (GSR) on menstrual pattern in women with stages III-IV obesity and ovulatory dysfunction compared with conventional management. METHODS This was a prospective, multicentre, non-randomized trial, in premenopausal women, who fulfilled the criteria for gastric sleeve resection (GSR). Both women with and without polycystic ovary syndrome (PCOS) were evaluated at 3, 6, 9, 12 and 15 months post-surgery. RESULTS Menstrual cycle irregularities were identified in 122 severely obese women (60 with PCOS; 62 without PCOS). The % total weight loss was greater with GSR than with conventional management (33.4% vs. 3.6% in PCOS; 24.8% vs. 3.6% in non-PCOS, respectively). Intermenstrual interval was shortened towards normal length (≤ 35 days) both in PCOS and non-PCOS GSR groups, by the 6th and 12th post-surgical month, respectively. Furthermore, ovulation at 6 months was achieved in 63.6% of PCOS and 45% of non-PCOS subjects post-GSR, which was higher than in controls (11.1% and 13.6%, respectively; p < 0.05). This percentage rose to 75.7% and 81.8% at 12 and 15 months in PCOS, respectively, but not in the non-PCOS group (55% and 52.5%, respectively; p < 0.05). CONCLUSIONS Weight reduction after GSR improved menstrual irregularity towards normality in women with severe obesity. Ovulation dysfunction was also resumed in more than half of these patients at 6-15 months. These effects were more evident in women with PCOS.

Abstract
BACKGROUND Bariatric surgery is an effective treatment for severe obesity. Several studies have been conducted on the effects of bariatric surgery on the reproductive function of women with obesity who do not have polycystic ovary syndrome (PCOS). OBJECTIVES To evaluate the effects of bariatric surgery on the menstruation and reproductive related hormones of women of childbearing age with who do not have PCOS. SETTING A systematic review and meta-analysis at a university hospital. METHODS Online databases were searched for all studies reporting the efficacy of bariatric surgery for women with obesity until March 2021. The language of publication was limited to English and Chinese. Incidence of abnormal menstruation and reproductive-related hormone levels were the primary outcomes. RESULTS Fifteen studies comprising 725 patients were enrolled in this meta-analysis. Results showed a significantly lower incidence of abnormal menstruation (relative risk: .40, 95% confidence interval [CI]: .20-.79, P = .008) after bariatric surgery. Moreover, bariatric surgery led to a decrease in serum insulin levels (mean difference [MD] = -13.12 mIU/L, 95% CI: -15.03 to -11.22, P < .00001), glucose (MD = -.91 mmol/L, 95% CI: -1.26 to -.56, P < .00001), triglyceride (MD = -.61 g/L, 95% CI: -.76 to -.46, P < .00001), total testosterone (MD = -.22 ng/mL, 95% CI: -.24 to -.20, P < .00001), dehydroepiandrosterone (DHEA) (MD = -25.34 μg/dL, 95% CI: -31.19 to -19.49, P < .00001), estradiol (MD = -25.13 pg/mL, 95% CI: -34.13 to -16.13, P < .00001), and anti-Mullerian hormone (AMH) (MD = -.40 ng/mL, 95% CI: -.67 to -.13, P = .003). Serum sex hormone binding globulin (SHBG) levels increased after bariatric surgery (MD = 43.99 nmol/L, 95% CI: 34.99-52.99, P < .00001). CONCLUSION Bariatric surgery can lower fasting insulin, glucose, and triglyceride levels, reduce the incidence of abnormal menstruation, decrease total serum testosterone, DHEA, estradiol, and AMH levels, and increase SHBG level for women with obesity of childbearing age who do not have PCOS. This meta-analysis indicated that bariatric surgery could be effective in improving reproductive function for women with severe obesity.

Abstract
INTRODUCTION The worldwide obesity epidemic has resulted in a rise of bariatric surgery in women of reproductive age, which can lead to 'iatrogenic undernutrition'. Long-lasting undernutrition can affect maternal health, pregnancy outcomes and offspring. We hypothesise that embryonic and placental growth are impaired in pregnancies after bariatric surgery due to the changed nutritional and microbiome dynamics. Therefore, our aim is to conduct the Bariatrics and EmbrYONic Development (BEYOND) study to investigate parameters of maternal nutritional and health status after bariatric surgery, both periconceptionally and during pregnancy, particularly concentrating on embryonic and fetal growth trajectories as well as placental development. METHODS AND ANALYSIS We designed a single-centre prospective, observational cohort, which investigates the iatrogenic nutritional and health status of women after bariatric surgery, periconceptionally and during pregnancy. The BEYOND study is embedded in the Rotterdam Periconceptional Cohort, a tertiary hospital-based birth cohort study. Eligible participants are women planning pregnancy or <12+0 weeks pregnant, ≥18 and ≤45 years of age, who have undergone bariatric surgery (cases) or without prior bariatric surgery (controls) and their male partners. Medical charts will be reviewed and questionnaires regarding general health, lifestyle and food intake will be collected. Moreover, we will perform serial three-dimensional ultrasounds to assess embryonic growth and placental development and two-dimensional ultrasounds for fetal growth assessment. The microbiome, including the virome, and blood samples will be sampled during the preconception period and in each trimester. Multivariable linear mixed model analyses will be used to assess the associations between bariatric surgery and pregnancy outcomes. ETHICS AND DISSEMINATION This proposal was approved by the Medical Ethics Committee from the Erasmus MC, Rotterdam, The Netherlands. Study results will be submitted for publication in high-impact journals, presented at scientific conferences, implemented into guidelines and communicated through the Erasmus MC and collaborating partners. TRIAL REGISTRATION NUMBER NL8217 (www.trialregister.nl).

Abstract
BACKGROUND Worldwide, the prevalence of obesity in women of reproductive age is increasing. Bariatric surgery is currently viewed as the most effective, long-term solution for this problem. Preconception bariatric surgery can reduce the prevalence of obesity-related subfertility and adverse maternal, pregnancy and birth outcomes. Maternal health during the periconception period is crucial for optimal gametogenesis and for embryonic and fetal development which also affects health in the later lives of both mother and offspring. Although preconception bariatric surgery improves several pregnancy outcomes, it can also increase the prevalence of pregnancy complications due to excessive and rapid weight loss. This can lead to iatrogenic malnutrition with vitamin deficiencies and derangements in metabolic and endocrine homeostasis. Thus, bariatric surgery can greatly influence periconception maternal health with consequences for reproduction, pregnancy and health in later life. However, its influence on periconception maternal health itself has never been reviewed systematically. OBJECTIVE AND RATIONALE The aim of this review was to investigate associations between bariatric surgery and determinants of periconception maternal health such as endocrine changes, fertility, vitamin status, irregular menstrual cycles, miscarriages and congenital malformations. SEARCH METHODS Medline, Embase, PubMed, Web of Science, Google Scholar and the Cochrane databases were used for the literature search until 1 November 2020. The search strategy terms included, among others, bariatric surgery, hormones, fertility, malformations, miscarriages and vitamin status. We searched for human studies that were written in English. Abstracts, reviews, meta-analyses and conference papers were excluded. The ErasmusAGE score was used to assess the quality of the included studies. OUTCOMES A total of 51 articles were analysed. The mean quality score was 5 (range 2-8). After bariatric surgery, hormonal axes normalized and menstrual cycle regularity was restored, resulting in increased fertility. Overall, there were no short-term risks for reproductive outcomes such as the increased risk of miscarriages or congenital malformations. However, the risk of vitamin deficiencies was generally increased after bariatric surgery. A meta-analysis of 20 studies showed a significant decrease in infertility (risk difference (RD) -0.24, 95% confidence interval (CI) -0.42, -0.05) and menstrual cycle irregularities (RD -0.24, 95% CI -0.34, -0.15) with no difference in rates of miscarriage (RD 0.00, 95% CI -0.09, 0.10) and congenital malformations (RD 0.01, 95% CI -0.02, 0.03). WIDER IMPLICATIONS The current systematic review and meta-analysis show associations between bariatric surgery and periconception maternal health and underlines the need for providing and personalizing preconception care for women after bariatric surgery. We recommend preconception care including the recommendation of postponing pregnancy until weight loss has stabilized, irrespective of the surgery-to-pregnancy interval, and until vitamin status is normalized. Therefore, regular monitoring of vitamin status and vitamin supplementation to restore deficiencies is recommended. Furthermore, this systematic review emphasizes the need for a long-term follow-up research of these women from the periconception period onwards as well as their pregnancies and offspring, to further improve care and outcomes of these mothers and children.

Abstract
The dramatic increase in the prevalence of obesity coincides with a decline in reproductive health indices in both sexes. Energy excess mediates changes to the regulatory mechanisms of the reproductive system. Obese individuals exhibit increased estrogen concentrations, due to the overexpression of aromatase in the adipose tissue; via a negative feedback loop, men present with symptoms of hypogonadotropic hypogonadism. These hormonal changes, along with increased oxidative stress, lipotoxicity and disturbances in the concentrations of adipokines, directly affect the gonads, peripheral reproductive organs and the embryo. Clinical evidence is somewhat contradicting, with only some studies advocating worse semen parameters, increased incidence of erectile dysfunction, increased doses of ovulation induction medications, and worse live birth rates in assisted reproductive technology (ART) cycles in obese individuals compared with those of normal weight. Similar conclusions are drawn about patients with insulin resistance syndromes, namely polycystic ovary syndrome (PCOS). As far as treatment options are concerned, lifestyle changes, medical therapy and bariatric surgery may improve the reproductive outcome, although the evidence remains inconclusive. In this review, we summarize the evidence on the association of obesity and reproductive health on both the molecular and the clinical level, and the effect of weight-loss interventions on reproductive potential.

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
BACKGROUND Women with obesity who become pregnant after bariatric surgery have a reduced risk of several obstetric complications; however, limited data exist from the UK population. The present study aimed to characterise a case series of women who attended a medical antenatal clinic for pregnancy following bariatric surgery. METHODS Routine clinical information was collected retrospectively from the medical notes of women who had bariatric surgery and subsequently delivered between January 2012 and November 2018. All were seen in the medical antenatal clinic at Musgrove Park Hospital, Taunton. RESULTS Data were available for 46 pregnancies. Of these, 27.9% conceived in the first year after surgery. At 9 weeks of gestation, 13.3%, 28.9%, 33.3% and 24.4% were in the healthy, overweight, obese or severely obese category, respectively. Mean (SD) gestational weight gain was 11.9 (6.9) kg, with 54.1% gaining excess weight. Less than half (39.1%) of women were taking the recommended dose of 5 mg of folic acid when first seen. Some 56.1% and 64.6% had suboptimal iron or vitamin D statuses, respectively. Following advice from the clinic, a greater proportion of women took suitable micronutrient supplements. Subsequently, 93% of babies were born at full term, of whom 88% were of healthy weight. CONCLUSIONS Despite the nutritional risks associated with bariatric surgery and the high prevalence of obesity during pregnancy, perinatal outcomes were generally positive, with low rates of infants born preterm or low birth weight. Nutritional supplementation practices and iron status improved with input from a specialist team, underlying the importance of individualised input in this population.

Abstract
INTRODUCTION The link between obesity epidemic in fertile age and fertility reduction, in relation with BMI increase, has been demonstrated. An inverse proportionality between BMI and anti-Müller hormone (AMH) has been investigated. This hormone is strictly related to ovarian function. It has been demonstrated that it is significantly decreased in obese women. SCOPE The aim of this study was evaluation of AMH levels in 53 obesity women with BMI >35, at 3 and 6 months after laparoscopic sleeve gastrectomy (LSG). Specific evaluation of comorbidities and of gynecological effects of weight loss was also evaluated. RESULTS Cohort of 53 women was considered, treated with LSG. A progressive increase of AMH levels after LSG was confirmed, with statistically significant results at followup of 6 months. In these patients, we also observed an improvement in the menstrual cycle and resolution of dysmenorrhea. All considered comorbidities were ameliorated at both followup. CONCLUSION LSG determined a significant increase of AMH level in women, at early followup, with a comprehensive amelioration of gynecological status. Larger cohorts and a better evaluation of ovarian function after LSG will lead to more powerful results of the effect of weight loss on women.

Serum proteome changes and accelerated reduction of fat mass after laparoscopic gastric plication in morbidly obese patients. J Proteomics 2019; 203:103373. [PMID: 31054967 DOI: 10.1016/j.jprot.2019.05.001] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2019] [Revised: 04/29/2019] [Accepted: 05/01/2019] [Indexed: 02/06/2023]
Abstract
Laparoscopic Gastric Plication (LGP) is a relatively new bariatric surgical procedure which no part of the stomach is removed. It is not clearly understood how LGP leads to fatty tissue reduction. We aimed to investigate the impact of LGP on serum proteome and understand molecular mechanisms of LGP-induced weight loss post-surgery. A Prospective observational study of 16 obese individuals who underwent LGP was performed. A Label-free quantitative shotgun proteomics approach was used to compare serum proteome of subjects before surgery with serum of the same individuals 1 to 2 months post-surgery (T1) and 4 to 5 months post-surgery (T2). The proteome analysis revealed that 48 proteins were differentially regulated between pre-surgery and T1, and seven proteins between pre-surgery and T2 of which six proteins were shared between the two timepoints. Among differentially regulated proteins, four proteins (SRGN, FETUB, LCP1 and CFP) have not previously been described in the context of BMI/weight loss. Despite few differences following LGP, most regulated serum proteins are in accordance with alternative weight loss procedures. Pathway analysis revealed changes to lipid- and inflammatory pathways, including PPARα/RXRα, LXR/RXR and FXR/RXR activation, especially at T1. At T2, the pathways related to inflammation and immune system are most affected. SIGNIFICANCE: Among the available clinical therapies for morbid obesity, bariatric surgery is considered as the most effective approach to achieve long-term weight loss, alongside a significant improvement in metabolic syndrome. However, very little is known about the underlying mechanism associated with significant weight loss post-surgery. Understanding such mechanisms could lead to development of safer non-surgical weight loss approaches. We here present the first analysis of the impact of LGP on the serum proteome, to bring new insights into the underlying molecular mechanism. Our findings indicate that LGP has a comprehensive systemic effect based on the blood serum proteome profile which might account for accelerated reduction of fat mass after surgery, thus, food restriction is not the only reason for weight loss following this unique surgical approach. As secretory regions of the stomach are preserved in LGP and it is associated with minimal physiological and anatomical changes, the findings are of high importance in the field of bariatric surgery and weight loss.
