Medicine (Baltimore) 2024; 103:e39030. [PMID: 39093743 PMCID: PMC11296412 DOI: 10.1097/md.0000000000039030] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/16/2024] [Accepted: 07/01/2024] [Indexed: 08/04/2024] Open
Abstract
In this study, we analyzed the clinical efficacy of Zishen Yutai pills (ZSYTP) combined with metformin hydrochloride on infertile women diagnosed with polycystic ovary syndrome (PCOS) undergoing in vitro fertilization and embryo transfer (IVF-ET). Patients were assigned into 3 groups: the ZSYTP group (n = 50), the metformin group (n = 50), and the combination group (ZSYTP combined with metformin hydrochloride, n = 50), based on their respective and the indicated treatments before undergoing IVF-ET. Then, their glucose metabolism indices, sex hormone indices, traditional Chinese medicine (TCM) syndrome scores, and outcomes of IVF-ET were compared. Baseline characteristics were not significantly different between the 2 groups. After treatment, various parameters such as body mass index (BMI), fasting plasma glucose (FPG), fasting insulin (FIN), homeostatic model assessment of insulin resistance (HOMA-IR), luteinizing hormone (LH), estradiol (E2), follicle-stimulating hormone (FSH), testosterone (T) levels, and TCM syndrome scores were found to be reduced compared to pretreatment levels in both groups. Moreover, the improvement observed in the treatment group exceeded that of the control group. Specifically, the observation group displayed significantly lower gonadotropin (Gn) dosage and duration, as well as a reduced abortion rate compared to the control group. Furthermore, the observation group had higher numbers of obtained eggs, high-quality embryos, eggs obtained through IVF-ET, average transferred embryos, clinical pregnancy rate, and embryo implantation rate compared to the control group. Pretreatment with ZSYTP combined with metformin before IVF-ET in PCOS patients improves the outcome of IVF-ET.

Abstract
Infertility affects 15% of couples in reproductive age worldwide. In women in particular, infertility can be caused by various abnormalities, with polycystic ovary syndrome (PCOS) being the most common. Currently, there are many assisted reproductive techniques (ART) available to combat the burden of infertility. However, positive results are not guaranteed. The administration of inositol has been shown to increase positive reproductive outcomes in women undergoing ART. Here we present a series of clinical cases in which women with a history of infertility and previously failed ART, supplemented with a specific 3.6:1 MYO:DCI ratio, antioxidants, vitamins, and minerals for a period of 1 to 3 months before undergoing in vitro fertilization (IVF). In this series of case reports, we provide preliminary evidence that supplementation with a specific 3.6:1 MYO to DCI ratio, as well as antioxidants, vitamins, and minerals may contribute positively to female fertility in women undergoing IVF, with a history of primary or secondary infertility and previously failed ART.

Abstract
OBJECTIVE This document purpose is to create an evidence-based position statement on the role of metformin therapy in pregnancy complicated by obesity, gestational diabetes (GDM), type 2 diabetes mellitus (T2DM), polycystic ovary syndrome (PCOS) and in women undergoing assisted reproductive technology (ART). METHODS A comprehensive review of international diabetes guidelines and a search of medical literature was performed to identify studies presenting data on the use of metformin in pregnancy. The document was approved by the councils of the two scientific societies. RESULTS In condition affecting the fertility, as PCOS, metformin use in pre-conception or early in pregnancy may be beneficial for clinical pregnancy, even in ART treatment, and in obese-PCOS women may reduce preterm delivery. In obese women, even in the presence of GDM or T2DM, metformin use in pregnancy is associated with a lower gestational weight gain. In pregnancy complicated by diabetes (GDM or T2DM), metformin improves maternal glycemic control and may reduce insulin dose. Neonatal and infant outcomes related to metformin exposure in utero are lacking. Metformin use in women with GDM or T2DM is associated with lower birth weight. However, an increased tendency to overweight-obesity has been observed in children, later in life. CONCLUSIONS Metformin may represent a therapeutic option in selected women with obesity, PCOS, GDM, T2DM, and in women undergoing ART. However, more research is required specifically on the long-term effects of in utero exposition to metformin.

Abstract
Polycystic ovarian syndrome (PCOS) is a widespread syndrome that poses unique challenges and constraints to the field of assisted reproductive technology. This condition is the most common cause of anovulation among infertile couples. Debate exists over the best therapeutic course of action when patients with PCOS proceed to IVF. In this review, we evaluate the best-performing and safest methods of IVF preparation, ovarian stimulation, trigger method for maturation of stimulated egg growth, and planning for embryo transfer. Pre-IVF considerations include being aware of individual AMH and vitamin D levels as well as BMI prior to selecting an ovarian stimulation protocol. Numerous supplements such as myo-inositol complement the benefits of lifestyle change and may enhance IVF performance including oocyte yield and pregnancy rate. Concerning stimulation protocols, antagonist cycles with the judicious use of GnRH agonist trigger, pre-treatment with metformin and vitamin D repletion may help mitigate the accompanied risk of ovarian hyperstimulation syndrome (OHSS). Following ovarian stimulation, PCOS patients typically undergo programmed frozen embryo transfer (FET) cycles which are more conducive for women with irregular cycles, but likely carry a higher risk of hypertensive disorders of pregnancy. However, newer stimulated FET protocols using Letrozole may offer improved outcomes. Overall, patients with PCOS require careful individual tailoring of their IVF cycle to achieve optimal results.

Abstract
Millions of women worldwide suffer from infertility associated with gynecologic disorders such as premature ovarian insufficiency, polycystic ovary syndrome, Asherman syndrome, endometriosis, preeclampsia, and fallopian tube obstruction. These disorders can lead to infertility and thereby affect the quality of life of the infertile couple because of their psychological impact and significant costs. In recent years, stem cell therapy has emerged as a therapeutic approach to repair or replace damaged tissues or organs. This review describes the recent development as well as the underlying mechanisms of stem cell therapy for a variety of female reproductive diseases, offering us new therapeutic options for the treatment of female reproductive and endocrine dysfunction.

Abstract
OBJECTIVE Our study aims to compare the effect of metformin, inositol and their combinations on the efficiency in improving outcomes of assisted reproductive technologies in women with PCOS. DATA SOURCES PubMed, The Cochrane Library, ClinicalTrials.gov, Embase, MEDLINE. The search was performed on studies published before November 14, 2021, to identify articles evaluating the effectiveness of treatment metformin and inositol on ART outcomes. STUDY SELECTION The systematic review was conducted according to the PRISMA 2020 checklist and registered in the PROSPERO 2021 CRD42021287887. Randomized controlled trials (RCTs) in English that compared metformin or inositol or metformin + inositol treatment with placebo or no treatment in women with PCOS undergoing assisted reproduction were included. In addition, RCTs with comparison combination and single metformin or inositol treatment were also included. DATA EXTRACTION AND SYNTHESIS 35 RCTs were included for qualitative analysis reporting on 4668 participants. In group of Metformin treatment were included 1891 patients, in Myo-inositol group - 281, in inositol + metformin group were included 110 participants and in control group (placebo or absence of treatment) - 1865 women with PCOS. 5 meta-analyses were performed. CPR in comparison of metformin and placebo in 1312 patients were higher in metformin group (RR = 1.30, 95% CI: 1.12 to 1.50, p = 0.0004). OHSS was less in metformin (RR = 0.34, 95% CI: 0.17 to 0.69, p = 0.003). However, LBR were not statistically significant (RR = 1.12, 95% CI: 0.93 to 1.36, p = 0.24). In comparison of inositol and no treatment there was also no difference in CPR (RR = 1.37, 95% CI: 0.79 to 2.38, p = 0.26). As for metformin and inositol meta-analysis in 220 patients with PCOS, CPR were higher in inositol group (RR = 1.52, 95% CI: 1.05 to 2.18, p = 0.03). Combination treatment included only two RCTs and was illegible for meta-analysis. CONCLUSION To our knowledge, it is the first meta-analysis that estimates inositol treatment compared to metformin. Based on our systematic review and meta-analysis, metformin seems to be a good option for improving ART outcomes in women with PCOS. However, it is not clear whether inositol usage is adequate. Nevertheless, we need more clinical trials of good quality to answer all questions thoroughly.

Abstract
Polycystic ovary syndrome (PCOS), the most common endocrinopathy in women is characterized by polycystic ovaries, chronic anovulation and hyperandrogenism. The treatment in PCOS is mainly symptomatic and involves lifestyle interventions and medications such as Metformin, Oral contraceptives and Antiandrogens. However, the management of PCOS is challenging and current interventions are not able to deal with outcomes of this syndrome. This review encompasses latest pharmacotherapeutic and non-pharmacotherapeutic interventions currently in use to tackle various symptomatic contentions in PCOS. Our focus has been mainly on novel therapeutic modalities for treatment/management of PCOS, like use of newer insulin sensitizers viz., Inositols, Glucagon-like peptide-1(GLP-1) agonists, Dipeptidyl pepdidase-4 (DPP-4) inhibitors, and sodium-glucose transport protein 2 (SGLT2) inhibitors. Also, evidence suggesting the use of vitamin D, statins, and Letrozole as emerging therapies in PCOS have been summarized in this review. Additionally, novel cosmetic techniques like electrolysis, laser and use of topically applied eflornithine to tackle the most distressing feature of facial hirsutism associated with PCOS, non-pharmacological therapy like acupuncture and the role of herbal medicine in PCOS management have also been discussed.

Abstract
OBJECTIVE To study the effects of myoinositol (Myo) in comparison to metformin (Met), in reducing the risk of OHSS and improving ART outcome in PCOS women undergoing IVF. DESIGN Double-blinded randomized controlled trial (CTRI/2018/05/014196). SETTING ART Clinic, AIIMS, New Delhi patients: 102 infertile PCOS women undergoing IVF cycles were enrolled after evaluating for eligibility and allotted as 50 in group 1 (Myo) and 52 in group 2 (Met) after randomization. INTERVENTIONS Recruited patients received Myo 2 g twice daily (group 1) and Met 850 mg twice daily (group 2). Pre- and post-treatment clinical (menstrual pattern, BMI), hormonal profile (LH, FSH, testosterone, prolactin [PRL], and AMH), biochemical parameters (HOMA IR, fasting glucose, and insulin), ovarian with antral follicle count (AFC) and side effect profile were assessed. After 3 months of therapy, patients were recruited for IVF cycle by antagonist protocol was involving controlled ovarian stimulation, cycle monitoring, oocyte recovery, insemination of oocytes and follow up with fertilization, cleavage, transfer of good grade cleavage embryos, or blastocysts pregnancy outcomes and OHSS incidence and medications was continued until the day of OPU. MAIN OUTCOME MEASURES Primary outcome was OHSS and clinical pregnancy rate including spontaneous, IVF, and cumulative pregnancy rate including FET. Secondary outcome was ART outcomes and the change in biochemistry and hormonal profile between groups and inter group after medications at 12 weeks. RESULTS Incidence of OHSS (Myo 5 (10.0) (n = 50), Met 10 (20.0) (n = 50) p .07) was not statistically different between groups. Clinical pregnancy rate (Myo 18 (36.0) (n = 50), Met 9 (18.0) (n = 50) p .04) cumulative pregnancy rate including FET (Myo 16 (43.2) (n = 37) vs. Met 10) 22.7) (n = 44) p .05) and spontaneous conception (prior to IVF) Myo 13 (26.0) (n = 50), Met 6 (12.0) (n = 50) p .07) was significantly high in Myo group. No between group difference in ovarian stimulation outcomes including duration and dosage of gonadotropins, E2, P4 levels, number of follicles >14 mm on day of trigger. Number of oocytes retrieved and grade of maturity were similar between groups. Fertilization, cleavage and number of good grade embryos were significantly higher in Myo group. However, implantation rate and number of embryos for freezing were similar between groups. Myo had improvement in fasting insulin, HOMA, Sr.AMH, and SHBG suggesting decreased insulin resistance. CONCLUSIONS Myo is equally beneficial as Met in reducing the risk of OHSS and has better ART outcome in PCOS women undergoing antagonist cycles.

Abstract
BACKGROUND Previous studies have described the effects of different drugs in preventing ovarian hyperstimulation syndrome (OHSS). However, the efficacies of those drugs in preventing OHSS remain inconclusive. METHODS We searched the PubMed, Web of Science, Embase, and Cochrane Central Register of Controlled Trials (CENTRAL) databases. A network meta-analysis of randomized controlled trials (RCTs) was performed up to August 2021. We investigated the following drugs in our study: aspirin, albumin, metformin, calcium, cabergoline, quinagolide, letrozole, hydroxyethyl starch (HES), and glucocorticoids. The primary outcome was the incidence rate of moderate-to-severe OHSS, with the results presented as risk ratios (RRs) with 95% confidence intervals (CIs). RESULTS The incidence of moderate-to-severe OHSS was significantly reduced by calcium administration (risk ratios [RR] 0.14, 95% confidence interval [CI]: 0.04, 0.46) (grade: high), HES (RR 0.25, 95% CI 0.07, 0.73) (grade: high), and cabergoline (RR 0.43, 95% CI 0.24, 0.71) (grade: moderate). The surface under the cumulative ranking curve (SUCRA) indicated that calcium (SUCRA, 92.4%) was the most effective intervention for preventing moderate-to-severe OHSS. These drugs were safe and did not affect clinical pregnancy, miscarriage, or live birth rates. CONCLUSION Calcium, HES, and cabergoline could effectively and safely prevent moderate-to-severe OHSS, with calcium as the most effective intervention.

In Utero Exposure to Metformin Reduces the Fertility of Male Offspring in Adulthood. Front Endocrinol (Lausanne) 2021; 12:750145. [PMID: 34745014 PMCID: PMC8565088 DOI: 10.3389/fendo.2021.750145] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/30/2021] [Accepted: 09/17/2021] [Indexed: 12/11/2022] Open
Abstract
Metformin is a drug used for the treatment of type 2 diabetes and disorders associated with insulin resistance. Metformin is also used in the treatment of pregnancy disorders such as gestational diabetes. However, the consequences of foetal exposure to metformin on the fertility of exposed offspring remain poorly documented. In this study, we investigated the effect of in utero metformin exposure on the fertility of female and male offspring. We observed that metformin is detectable in the blood of the mother and in amniotic fluid and blood of the umbilical cord. Metformin was not measurable in any tissues of the embryo, including the gonads. The effect of metformin exposure on offspring was sex specific. The adult females that had been exposed to metformin in utero presented no clear reduction in fertility. However, the adult males that had been exposed to metformin during foetal life exhibited a 30% reduction in litter size compared with controls. The lower fertility was not due to a change in sperm production or the motility of sperm. Rather, the phenotype was due to lower sperm head quality - significantly increased spermatozoa head abnormality with greater DNA damage - and hypermethylation of the genomic DNA in the spermatozoa associated with lower expression of the ten-eleven translocation methylcytosine dioxygenase 1 (TET1) protein. In conclusion, while foetal metformin exposure did not dramatically alter gonad development, these results suggest that metabolic modification by metformin during the foetal period could change the expression of epigenetic regulators such as Tet1 and perturb the genomic DNA in germ cells, changes that might contribute to a reduced fertility.

Abstract
The aim of this study was to compare the efficacy of calcium infusion versus cabergoline in the prevention of ovarian hyperstimulation syndrome (OHSS) in IVF patients at high risk for OHSS. One hundred and seventy patients who were stimulated using the long luteal GnRH agonist protocol and at high risk for developing OHSS were randomised in a 1:1 ratio to cabergoline group and calcium gluconate group. In cabergoline group, 0.5 mg of cabergoline was administered once daily p.o. for eight days starting on the day of HCG administration. In calcium gluconate group, intravenous calcium gluconate (10%, 10 ml in 200 ml of physiologic saline) was administered daily for four days starting on the day of ovum pickup. Six patients in cabergoline group and eight patients in calcium gluconate group developed moderate OHSS. One patient in each group developed severe OHSS. The incidence of moderate/severe OHSS was comparable between both groups (8.24% vs. 10.59%, p value = .599, OR = 0.76, 95% CI [0.269-2.138]). The implantation, clinical and ongoing pregnancy rates were similar in the two groups (16.91% vs. 15.84%, p = .771, 35.29% vs. 32.94%, p = .746, and 30.59% vs. 28.24%, p = .736, respectively). In conclusion, calcium infusion and cabergoline have comparable effectiveness in the prevention of OHSS. Both drugs are well tolerated, cheap and have no adverse effects on the reproductive outcomes of IVF cycle.Clinical trial registration: The trial was registered on clinical trials.gov database [NCT02875587].Impact StatementWhat is already known on this subject? The effectiveness of cabergoline in the prevention of OHSS in IVF patients at high risk for OHSS is confirmed by overwhelming scientific evidence. Calcium infusion is a novel strategy for prevention of OHSS. Few studies reported the use of calcium infusion in the prevention of OHSS. A retrospective study and a randomised controlled study revealed that calcium infusion reduces the incidence of OHSS. Moreover, a quasi-randomised study revealed that calcium infusion is as effective as cabergoline in the prevention of OHSS.What the results of this study add? Calcium infusion and cabergoline have comparable effectiveness in the prevention of OHSS. Both drugs are well tolerated, cheap and have no adverse effects on the reproductive outcomes of IVF cycle.What the implications are of these findings for clinical practice and/or further research? Calcium infusion should be used to minimise the incidence of OHSS in IVF patients at high risk for OHSS.

Reprod Biol Endocrinol 2021; 19:89. [PMID: 34127011 PMCID: PMC8201680 DOI: 10.1186/s12958-021-00772-7] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/04/2021] [Accepted: 05/28/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND This meta-analysis summarizes evidence from studies using metformin (Met) to improve endometrial receptivity (ER) in women with PCOS. METHODS Following the PRISMA protocol, we conducted a comprehensive search of academic literature from various databases, including PubMed, EMbase and Cochrane libraries. Studies published in English before Jan 27, 2021, were recruited for primary screening. Data on endometrial thickness (EMT), endometrial artery resistance index (RI), clinical pregnancy rate (CPR) and miscarriage rate (MR) were extracted and analyzed. RESULTS Sixty-two eligible studies that included 6571 patients were evaluated in this meta-analysis. Primary indicators are EMT and endometrial aetery RI; secondary indicators include the clinical pregnancy rate and miscarriage rate. Metformin significantly increased EMT (SMD = 2.04, 95% CI (0.96,3.12),P = 0.0002) and reduced endometrial artery RI compared to the non-Met group (SMD = - 2.83, 95% CI: (- 5.06, - 0.59), P = 0.01). As expected, metformin also improved CPR and reduced MR in PCOS patients as a result, clinical pregnancy rate (risk ratio [RR] = 1.26, 95% CI: 1.11-1.43, P = 0.0003), and miscarriage rate (RR = 0.73, 95% CI:0.58-0.91, P = 0.006). CONCLUSION Metformin may improve endometrial receptivity (ER) in PCOS patients by increasing EMT and reducing endometrial artery RI. However, the level of most original studies was low, with small sample sizes. More large-scale, long-term RCTs with rigorous methodologies are needed.

Abstract
BACKGROUND Clinicians primarily recommend weight loss for obese women seeking pregnancy. The effectiveness of interventions aimed at weight loss in obese women with subfertility is unclear. OBJECTIVES To assess the effectiveness and safety of pharmacological and non-pharmacological strategies compared with each other, placebo, or no treatment for achieving weight loss in obese women with subfertility. SEARCH METHODS We searched the CGF Specialised Register, CENTRAL, MEDLINE, Embase, PsycINFO, and AMED from inception to 18 August 2020. We also checked reference lists and contacted experts in the field for additional relevant papers. SELECTION CRITERIA We included published and unpublished randomised controlled trials in which weight loss was the main goal of the intervention. Our primary effectiveness outcomes were live birth or ongoing pregnancy and primary safety outcomes were miscarriage and adverse events. Secondary outcomes included clinical pregnancy, weight change, quality of life, and mental health outcome. DATA COLLECTION AND ANALYSIS Review authors followed standard Cochrane methodology. MAIN RESULTS This review includes 10 trials. Evidence was of very low to low quality: the main limitations were due to lack of studies and poor reporting of study methods. The main reasons for downgrading evidence were lack of details by which to judge risk of bias (randomisation and allocation concealment), lack of blinding, and imprecision. Non-pharmacological intervention versus no intervention or placebo Evidence is insufficient to determine whether a diet or lifestyle intervention compared to no intervention affects live birth (odds ratio (OR) 0.85, 95% confidence interval (CI) 0.65 to 1.11; 918 women, 3 studies; I² = 78%; low-quality evidence). This suggests that if the chance of live birth following no intervention is assumed to be 43%, the chance following diet or lifestyle changes would be 33% to 46%. We are uncertain if lifestyle change compared with no intervention affects miscarriage rate (OR 1.54, 95% CI 0.99 to 2.39; 917 women, 3 studies; I² = 0%; very low-quality evidence). Evidence is insufficient to determine whether lifestyle change compared with no intervention affects clinical pregnancy (OR 1.06, 95% CI 0.81 to 1.40; 917 women, 3 studies; I² = 73%; low-quality evidence). Lifestyle intervention resulted in a decrease in body mass index (BMI), but data were not pooled due to heterogeneity in effect (mean difference (MD) -3.70, 95% CI -4.10 to -3.30; 305 women, 1 study; low-quality evidence; and MD -1.80, 95% CI -2.67 to -0.93; 43 women, 1 study; very low-quality evidence). Non-pharmacological versus non-pharmacological intervention We are uncertain whether intensive weight loss interventions compared to standard care nutrition counselling affects live birth (OR 11.00, 95% CI 0.43 to 284; 11 women, 1 study; very low-quality evidence), clinical pregnancy (OR 11.00, 95% CI 0.43 to 284; 11 women, 1 study; very low-quality evidence), BMI (MD -3.00, 95% CI -5.37 to -0.63; 11 women, 1 study; very low-quality evidence), weight change (MD -9.00, 95% CI -15.50 to -2.50; 11 women, 1 study; very low-quality evidence), quality of life (MD 0.06, 95% CI -0.03 to 0.15; 11 women, 1 study; very low-quality evidence), or mental health (MD -7.00, 95% CI -13.92 to -0.08; 11 women, 1 study; very low-quality evidence). No study reported on adverse events . Pharmacological versus pharmacological intervention For metformin plus liraglutide compared to metformin we are uncertain of an effect on the adverse events nausea (OR 7.22, 95% CI 0.72 to 72.7; 28 women, 1 study; very low-quality evidence), diarrhoea (OR 0.31, 95% CI 0.01 to 8.3; 28 women, 1 study; very low-quality evidence), and headache (OR 5.80, 95% CI 0.25 to 133; 28 women, 1 study; very low-quality evidence). We are uncertain if a combination of metformin plus liraglutide vs metformin affects BMI (MD 2.1, 95% CI -0.42 to 2.62; 28 women, 1 study; very low-quality evidence) and total body fat (MD -0.50, 95% CI -4.65 to 3.65; 28 women, 1 study; very low-quality evidence). For metformin, clomiphene, and L-carnitine versus metformin, clomiphene, and placebo, we are uncertain of an effect on miscarriage (OR 3.58, 95% CI 0.73 to 17.55; 274 women, 1 study; very low-quality evidence), clinical pregnancy (OR 5.56, 95% CI 2.57 to 12.02; 274 women, 1 study; very low-quality evidence) or BMI (MD -0.3, 95% CI 1.17 to 0.57, 274 women, 1 study, very low-quality evidence). We are uncertain if dexfenfluramine versus placebo affects weight loss in kilograms (MD -0.10, 95% CI -2.77 to 2.57; 21 women, 1 study; very low-quality evidence). No study reported on live birth, quality of life, or mental health outcomes. Pharmacological intervention versus no intervention or placebo We are uncertain if metformin compared with placebo affects live birth (OR 1.57, 95% CI 0.44 to 5.57; 65 women, 1 study; very low-quality evidence). This suggests that if the chance of live birth following placebo is assumed to be 15%, the chance following metformin would be 7% to 50%. We are uncertain if metformin compared with placebo affects gastrointestinal adverse events (OR 0.91, 95% CI 0.32 to 2.57; 65 women, 1 study; very low-quality evidence) or miscarriage (OR 0.50, 95% CI 0.04 to 5.80; 65 women, 1 study; very low-quality evidence) or clinical pregnancy (OR 2.67, 95% CI 0.90 to 7.93; 96 women, 2 studies; I² = 48%; very low-quality evidence). We are also uncertain if diet combined with metformin versus diet and placebo affects BMI (MD -0.30, 95% CI -2.16 to 1.56; 143 women, 1 study; very low-quality evidence) or waist-to-hip ratio (WHR) (MD 2.00, 95% CI -2.21 to 6.21; 143 women, 1 study; very low-quality evidence). Pharmacological versus non-pharmacological intervention No study undertook this comparison. AUTHORS' CONCLUSIONS Evidence is insufficient to support the use of pharmacological and non-pharmacological strategies for obese women with subfertility. No data are available for the comparison of pharmacological versus non-pharmacological strategies. We are uncertain whether pharmacological or non-pharmacological strategies effect live birth, ongoing pregnancy, adverse events, clinical pregnancy, quality of life, or mental heath outcomes. However, for obese women with subfertility, a lifestyle intervention may reduce BMI. Future studies should compare a combination of pharmacological and lifestyle interventions for obese women with subfertility.

Abstract
INTRODUCTION This review covers the current evidence regarding the use of metformin as a therapeutic intervention for optimizing pregnancy outcomes in women with polycystic ovary syndrome (PCOS). AREAS COVERED After searching Medline, Embase and CINAHL, all important large clinical trials and observational studies plus systematic reviews, meta-analyses and Cochrane reviews have been summarized here. The results have been compared to culminate in a thorough review and discussion on the use of metformin in relation to reproductive outcomes for women with PCOS. The role of metformin in PCOS is explored both in terms of achieving conception and during pregnancy. The existing evidence around metformin use is summarized both during the preconceptual period and during pregnancy, in relation to reproductive outcomes. EXPERT OPINION Metformin is a widely used medication, often prescribed to improve reproductive outcomes for women with PCOS. However, the evidence remains equivocal regarding its efficacy both in optimizing fertility and pregnancy outcomes. More research is required with special emphasis on metformin use within different populations, including ethnic groups and women with varying BMI ranges.

Abstract
PCOS has a wide range of negative impacts on women's health and is one of the most frequent reproductive systemic endocrine disorders. PCOS has complex characteristics and symptom heterogeneity due to the several pathways that are involved in the infection and the absence of a comm14on cause. A recent study has shown that the main etiology and endocrine aspects of PCOS are the increased level of androgen, which is also known as "hyperandrogenemia (HA)" and secondly the "insulin resistance (IR)". The major underlying cause of the polycystic ovary is these two IR and HA, by initiating the disease and its severity or duration. As a consequence, study on Pathogenesis is crucial to understand the effect of "HA" and "IR" on the pathophysiology of numerous symptoms linked to PCOS. A deep understanding of the pattern of the growth in PCOS for HA and IR can help ameliorate the condition, along with adjustments in nutrition and life, as well as the discovery of new medicinal products. However, further research is required to clarify the mutual role of IR and HA on PCOS development.

Abstract
In vitro fertilization is indicated for infertile women with polycystic ovarian syndrome (PCOS) after unsuccessful treatment with ovulation induction agents or in women deemed high-risk of multiple gestations who are ideal candidates for single embryo transfers. PCOS patients are at increased risk of ovarian hyperstimulation syndrome; therefore, attention should be made in the choice of in vitro fertilization treatment protocol, dose of gonadotropin utilized, and regimen to achieve final oocyte maturation. Adopting these strategies in addition to close monitoring may significantly reduce the ovarian hyperstimulation syndrome risk. Future developments may improve pregnancy outcomes and decrease complications in PCOS women undergoing fertility treatment.

Abstract
BACKGROUND The use of insulin-sensitising agents, such as metformin, in women with polycystic ovary syndrome (PCOS) who are undergoing ovulation induction or in vitro fertilisation (IVF) cycles has been widely studied. Metformin reduces hyperinsulinaemia and suppresses the excessive ovarian production of androgens. It is suggested that as a consequence metformin could improve assisted reproductive techniques (ART) outcomes, such as ovarian hyperstimulation syndrome (OHSS), pregnancy, and live birth rates. OBJECTIVES To determine the effectiveness and safety of metformin as a co-treatment during IVF or intracytoplasmic sperm injection (ICSI) in achieving pregnancy or live birth in women with PCOS. SEARCH METHODS We searched the Cochrane Gynaecology and Fertility Group Specialised Register, CENTRAL via the Cochrane Register of Studies Online (CRSO), MEDLINE, Embase, PsycINFO, LILACS, the trial registries for ongoing trials, and reference lists of articles (from inception to 13 February 2020). SELECTION CRITERIA Types of studies: randomised controlled trials (RCTs) comparing metformin treatment with placebo or no treatment in women with PCOS who underwent IVF or ICSI treatment. TYPES OF PARTICIPANTS women of reproductive age with anovulation due to PCOS with or without co-existing infertility factors. Types of interventions: metformin administered before and during IVF or ICSI treatment. PRIMARY OUTCOME MEASURES live birth rate, incidence of ovarian hyperstimulation syndrome. DATA COLLECTION AND ANALYSIS Two review authors independently selected the studies, extracted the data according to the protocol, and assessed study quality. We assessed the overall quality of the evidence using the GRADE approach. MAIN RESULTS This updated review includes 13 RCTs involving a total of 1132 women with PCOS undergoing IVF/ICSI treatments. We stratified the analysis by type of ovarian stimulation protocol used (long gonadotrophin-releasing hormone agonist (GnRH-agonist) or short gonadotrophin-releasing hormone antagonist (GnRH-antagonist)) to determine whether the type of stimulation used influenced the outcomes. We did not perform meta-analysis on the overall (both ovarian stimulation protocols combined) data for the outcomes of live birth and clinical pregnancy rates per woman because of substantial heterogeneity. In the long protocol GnRH-agonist subgroup, the pooled evidence showed that we are uncertain of the effect of metformin on live birth rate per woman when compared with placebo/no treatment (risk ratio (RR) 1.30, 95% confidence interval (CI) 0.94 to 1.79; 6 RCTs; 651 women; I2 = 47%; low-quality evidence). This suggests that if the chance for live birth following placebo/no treatment is 28%, the chance following metformin would be between 27% and 51%. Only one study used short protocol GnRH-antagonist and reported live birth rate. Metformin may reduce live birth rate compared with placebo/no treatment (RR 0.48, 95% CI 0.29 to 0.79; 1 RCT; 153 women; low-quality evidence). This suggests that if the chance for live birth following placebo/no treatment is 43%, the chance following metformin would be between 13% and 34% (short GnRH-antagonist protocol). We found that metformin may reduce the incidence of OHSS (RR 0.46, 95% CI 0.29 to 0.72; 11 RCTs; 1091 women; I2 = 38%; low-quality evidence). This suggests that for a woman with a 20% risk of OHSS without metformin, the corresponding risk using metformin would be between 6% and 14%. Using long protocol GnRH-agonist stimulation, metformin may increase clinical pregnancy rate per woman compared with placebo/no treatment (RR 1.32, 95% CI 1.08 to 1.63; 10 RCTs; 915 women; I2 = 13%; low-quality evidence). Using short protocol GnRH-antagonist, we are uncertain of the effect of metformin on clinical pregnancy rate per woman compared with placebo/no treatment (RR 1.38, 95% CI 0.21 to 9.14; 2 RCTs; 177 women; I2 = 87%; very low-quality evidence). We are uncertain of the effect of metformin on miscarriage rate per woman when compared with placebo/no treatment (RR 0.86, 95% CI 0.56 to 1.32; 8 RCTs; 821 women; I2 = 0%; low-quality evidence). Metformin may result in an increase in side effects compared with placebo/no treatment (RR 3.35, 95% CI 2.34 to 4.79; 8 RCTs; 748 women; I2 = 0%; low-quality evidence). The overall quality of evidence ranged from very low to low. The main limitations were inconsistency, risk of bias, and imprecision. AUTHORS' CONCLUSIONS This updated review on metformin versus placebo/no treatment before or during IVF/ICSI treatment in women with PCOS found no conclusive evidence that metformin improves live birth rates. In a long GnRH-agonist protocol, we are uncertain whether metformin improves live birth rates, but metformin may increase the clinical pregnancy rate. In a short GnRH-antagonist protocol, metformin may reduce live birth rates, although we are uncertain about the effect of metformin on clinical pregnancy rate. Metformin may reduce the incidence of OHSS but may result in a higher incidence of side effects. We are uncertain of the effect of metformin on miscarriage rate per woman.

Abstract
Nuclear pollution intertwined accidental irradiation not only triggers acute and chronic radiation syndromes, but also endangers embryonic development in sight of uncontrollable gene mutation. Metformin (MET), a classic hypoglycemic drug, has been identified to possess multiple properties. In this study, we explored the radioprotective effects of MET on the developmental abnormalities and deformities induced by irradiation among three "star drugs". Specifically, zebrafish (Danio rerio) embryos exposed to 5.2 Gy gamma irradiation at 4 h post fertilization (hpf) showed overt developmental toxicity, including hatching delay, hatching rate decrease, developmental indexes reduction, morphological abnormalities occurrence and motor ability decline. However, MET treatment erased the radiation-induced phenotypes. In addition, MET degraded inflammatory reaction, hinders apoptosis response, and reprograms the development-related genes expression, such as sox2, sox3, sox19a and p53, in zebrafish embryos following radiation challenge. Together, our findings provide novel insights into metformin, and underpin that metformin might be employed as a promising radioprotector for radiation-induced early developmental toxicity in pre-clinical settings.

Abstract
IMPORTANCE Metformin is widely used among women with polycystic ovary syndrome (PCOS). However, its associations with outcomes of in vitro fertilization or intracytoplasmic sperm injection and embryo transfer (IVF/ICSI-ET) in women with PCOS remain controversial. OBJECTIVE To assess whether metformin is associated with improved outcomes of IVF/ICSI-ET in women with PCOS. DATA SOURCES PubMed, Embase, and Cochrane were searched from database inception to January 31, 2020. STUDY SELECTION Only randomized clinical trials (RCTs) were included. Eligible studies enrolled women with PCOS undergoing infertility treatment with IVF/ICSI-ET and reported at least 1 outcome of IVF/ICSI-ET. DATA EXTRACTION AND SYNTHESIS This study followed the Preferred Reporting Items for Systematic Reviews and Meta analyses guidelines. Two authors independently extracted the data. Study quality was evaluated using the GRADE system. Treatment effect was quantified using odds ratios (ORs) with 95% CIs using random-effect models with the Mantel-Haenszel method. MAIN OUTCOMES AND MEASURES Ovarian hyperstimulation syndrome (OHSS), clinical pregnancy rate, and live birth rate. RESULTS A total of 12 RCTs, which collectively included 1123 women with PCOS undergoing infertility treatment with IVF/ICSI-ET, were identified. The risk of OHSS in women randomized to metformin was lower than in women not randomized to metformin (OR, 0.43; 95% CI, 0.24-0.78), although this difference was not significant for women with PCOS with a body mass index of less than 26 (OR, 0.67; 95% CI, 0.30-1.51). There was no significant difference in clinical pregnancy rate (OR, 1.24; 95% CI, 0.82-1.86) or live birth rate (OR, 1.23; 95% CI, 0.74-2.04) in the total population studied. However, in a post hoc analysis among women with a body mass index of 26 or greater, metformin treatment was associated with increased clinical pregnancy rates (OR, 1.71; 95% CI, 1.12-2.60). CONCLUSIONS AND RELEVANCE In this study, metformin treatment was associated with a decreased risk of OHSS but had no association with the overall clinical pregnancy rate or live birth rate among women with PCOS undergoing IVF/ICSI-ET. Metformin treatment should be carefully considered for women with PCOS undergoing IVF/ICSI-ET and may be more preferred for women with a body mass index greater than 26.

Abstract
BACKGROUND Insulin resistance plays a major role in the pathogenesis of polycystic ovary syndrome (PCOS). Therefore, there is a growing interest in the use of insulin sensitizer drugs in the treatment of PCOS. Research in recent years has shown that sitagliptin has been reported to improve ovarian cycles and ovulation in PCOS patients. AIMS We aimed to compare the effects of metformin and sitagliptin on PCOS individuals undergoing ICSI. METHODS Sixty PCOS patients were divided into 3 groups: metformin, sitagliptin, and placebo group. Treatment was carried out 2 months before the start of the ovulation cycle and continued until the day of oocyte aspiration. The serum levels of total testosterone, estradiol, and fasting insulin along with the total number of retrieved, normal and abnormal MII, and fertilized oocytes, the number of transferred embryos (grades I, II and III), and biochemical and clinical pregnancy rates as well as the ovarian hyperstimulation syndrome (OHSS) were evaluated. RESULTS There was a significant reduction in the serum levels of Insulin and total testosterone in the treated groups compared with the placebo. The number of mature and normal MII oocytes increased significantly in the treated groups compared with the placebo. Moreover, the number of immature oocytes decreased significantly and the number of grade I embryos increases significantly in the sitagliptin group compared with the placebo group. CONCLUSION We conclude that sitagliptin can improve the maturation of oocytes and embryos' quality more effectively than metformin, in PCOS patients undergoing ICSI. TRIAL REGISTRATION Trial registration is NCT04268563 ( https://clinicaltrials.gov ).

Abstract
Ovarian hyperstimulation syndrome (OHSS) is a serious, almost exclusively, iatrogenic complication of ovarian stimulation. Many techniques have been developed over the past 25 years to decrease OHSS risks, and most have been in common use for 15-20 years. In view of these techniques, it could be hypothesized that severe OHSS rates would decrease or almost disappear. According to the US National ART Surveillance System, rates did not change significantly between 2000 and 2009, at 106 OHSS cases per 10,000 IVF cycles annually. In the present study, OHSS-related hospital admissions were evaluated to establish whether a decline has occurred in OHSS admissions since the development of preventative strategies. A retrospective-population-based study was conducted using data from the Health-Care Cost and Utilization Project-Nationwide-Inpatient-Sample database between 2004 and 2014 inclusively. Between 2004 and 2008, admissions of OHSS decreased in absolute numbers and rates; however, these statistics plateaued, remaining stable between 2008 and 2014. Despite this, OHSS remains a concern and is clearly not a disease of the past. The financial burden of OHSS hospitalizations likely persists. Although techniques have resulted in a decrease in OHSS admissions since 2004, this change has plateaued, and therefore efforts to further reduce OHSS must continue.

Abstract
Polycystic ovary syndrome (PCOS), characterized by polycystic ovarian morphology, ovarian follicular maturation arrest, and hormonal disorders, affects numerous women in the reproductive age worldwide. A recent study has found that mitochondria are likely to play an essential role in oocyte quality. However, it is still unclear whether oocyte development failure is associated with mitochondria in patients with PCOS. We analyzed the single-cell RNA sequencing data from the previous study, including data from 14 oocytes from 7 healthy fertile women and 20 oocytes from 9 patients with PCOS at the germinal vesicle (GV) stage, metaphase I (MI) stage, and metaphase II (MII) stage. We revealed the transcriptomic dynamics by weighted gene co-expression network analysis (WGCNA) and investigated the differences between stages using PCA and Deseq2 analyses to identify the differential expression genes (DEGs). Gene ontology (GO) was performed using clusterProfiler R package and Metascape. Our results indicated that specific gene modules were related to different stages of oocyte development using WGCNA. Functional enrichment analysis and gene co-expression network analysis found significant enrichment of the mitochondrial regulation genes at the GV stage. PCA (principal component analysis) and differential gene expression analysis suggested that GV was significantly different from the MI and MII stages between the two groups. Further analysis demonstrated that the upregulated differentially expressed genes at the GV stage of patients with PCOS mainly related to mitochondrial function, such as COX6B1, COX8A, COX4l1, and NDUFB9. Meanwhile, these genes tended to be activated at the MII stage in healthy cells, suggesting that some mitochondrial functions may be prematurely activated at the GV stage of PCOS oocytes, whereas this process occurs at the MII stage in healthy oocytes. Collectively, our study showed that aberrant mitochondrial function at the GV stage may contribute to a decline in oocyte quality of PCOS patients.

Abstract
This meta-analysis aimed to study whether pregnancy-related outcomes and complications differed between patients with polycystic ovary syndrome (PCOS) and those with other causes of infertility who had undergone IVF. A systematic search of PubMed, Embase, the Cochrane Library and Chinese databases was carried out to identify relevant studies published before July 2018. Outcomes were expressed as odds ratios (OR) and 95% confidence intervals (CI). Subgroup analyses and sensitivity analyses were also conducted. Twenty-nine studies were identified for inclusion. Women with PCOS had higher risks of miscarriage (OR 1.41, 95% CI 1.04-1.91), ovarian hyperstimulation syndrome (OR 4.96, 95% CI 3.73-6.60), gestational diabetes mellitus (OR 2.67, 95% CI 1.43-4.98), pregnancy-induced hypertension (OR 2.06, 95% CI 1.45-2.91), preterm birth (OR 1.60, 95% CI 1.25-2.04) and large-for-gestational-age babies (OR 2.10, 95% CI 1.01-4.37). Women with PCOS showed similar rates of clinical pregnancy, multiple pregnancy, ectopic pregnancy, small for gestational age and congenital malformations, and a higher live birth rate, compared with women without PCOS. This study provides an update on and comprehensive evidence to support the observation that despite the fact that PCOS patients achieve a better live birth rate, physicians should continue to consider them to be at high risk of adverse pregnancy-related outcomes.

Abstract
STUDY QUESTION What is the recommended assessment and management of infertile women with polycystic ovary syndrome (PCOS), based on the best available evidence, clinical expertize and consumer preference? SUMMARY ANSWER International evidence-based guidelines, including 44 recommendations and practice points, addressed prioritized questions to promote consistent, evidence-based care and improve the experience and health outcomes of infertile women with PCOS. WHAT IS KNOWN ALREADY Previous guidelines on PCOS lacked rigorous evidence-based processes, failed to engage consumer and multidisciplinary perspectives or were outdated. The assessment and management of infertile women with PCOS are inconsistent. The needs of women with PCOS are not being adequately met and evidence practice gaps persist. PARTICIPANTS/MATERIALS, SETTING, METHODS Governance included a six continent international advisory and a project board, a multidisciplinary international guideline development group (GDG), consumer and translation committees. Extensive health professional and consumer engagement informed the guideline scope and priorities. The engaged international society-nominated panel included endocrinology, gynaecology, reproductive endocrinology, obstetrics, public health and other experts, alongside consumers, project management, evidence synthesis and translation experts. Thirty-seven societies and organizations covering 71 countries engaged in the process. Extensive online communication and two face-to-face meetings over 15 months addressed 19 prioritized clinical questions involving nine evidence-based reviews and 10 narrative reviews. Evidence-based recommendations (EBRs) were formulated prior to consensus voting within the guideline panel. STUDY DESIGN, SIZE, DURATION International evidence-based guideline development engaged professional societies and consumer organizations with multidisciplinary experts and women with PCOS directly involved at all stages. A (AGREE) II-compliant processes were followed, with extensive evidence synthesis. The Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) framework was applied across evidence quality, desirable and undesirable consequences, feasibility, acceptability, cost, implementation and ultimately recommendation strength. The guideline was peer-reviewed by special interest groups across our partner and collaborating societies and consumer organizations, was independently assessed against AGREE II criteria and underwent methodological review. This guideline was approved by all members of the GDG and has been approved by the NHMRC. MAIN RESULTS AND THE ROLE OF CHANCE The quality of evidence (QOE) for the EBRs in the assessment and management of infertility in PCOS included very low (n = 1), low (n = 9) and moderate (n = 4) quality with no EBRs based on high-quality evidence. The guideline provides 14 EBRs, 10 clinical consensus recommendations (CCRs) and 20 clinical practice points on the assessment and management of infertility in PCOS. Key changes in this guideline include emphasizing evidence-based fertility therapy, including cheaper and safer fertility management. LIMITATIONS, REASONS FOR CAUTION Overall evidence is generally of low to moderate quality, requiring significantly greater research in this neglected, yet common condition. Regional health systems vary and a process for adaptation of this guideline is provided. WIDER IMPLICATIONS OF THE FINDINGS The international guideline for the assessment and management of infertility in PCOS provides clinicians with clear advice on best practice based on the best available evidence, expert multidisciplinary input and consumer preferences. Research recommendations have been generated and a comprehensive multifaceted dissemination and translation program supports the guideline with an integrated evaluation program. STUDY FUNDING/COMPETING INTEREST(S) The guideline was primarily funded by the Australian National Health and Medical Research Council of Australia (NHMRC) supported by a partnership with ESHRE and the American Society for Reproductive Medicine (ASRM). GDG members did not receive payment. Travel expenses were covered by the sponsoring organizations. Disclosures of conflicts of interest were declared at the outset and updated throughout the guideline process, aligned with NHMRC guideline processes. Dr Costello has declared shares in Virtus Health and past sponsorship from Merck Serono for conference presentations. Prof. Norman has declared a minor shareholder interest in the IVF unit Fertility SA, travel support from Merck and grants from Ferring. Prof. Norman also has scientific advisory board duties for Ferring. The remaining authors have no conflicts of interest to declare.

Improvement of oocyte in vitro maturation from mice with polycystic ovary syndrome by human mesenchymal stromal cell-conditioned media. J Cell Biochem 2018; 119:10365-10375. [PMID: 30171726 DOI: 10.1002/jcb.27380] [Citation(s) in RCA: 21] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2018] [Accepted: 07/03/2018] [Indexed: 12/15/2022]
Abstract
The outcome of in vitro maturation (IVM) in the patients with polycystic ovary syndrome (PCOS) is poor. Abnormal intraovarian paracrine interplay alters microenvironment for oocyte development through folliculogenesis and decreases developmental competence of oocytes in patients with PCOS. Mesenchymal stromal cells (MSCs) secrete a variety of cytokines and growth factors that could promote oocyte maturation in vitro. Thus, in the current study we aimed to evaluate the effect of human bone marrow MSC-conditioned media (hBM-MSC-CM), as a supplement, to enrich IVM medium for PCOS germinal vesicles (GVs). For this purpose, oocytes at GV and metaphase II (MII) stages were harvested from PCOS mice. The GVs were randomly divided into four groups and incubated for 24 hours in an IVM medium (TCM199, as the control group) or TCM199 supplemented by 25%, 50%, and 75% of hBM-MSC-CM (PCOS-CM25, PCOS-CM50, and PCOS-CM75 groups, respectively) so as to evaluate which dose(s) could enhance maturation rate of the GVs and their subsequent in vitro fertilization (IVF) outcome. Furthermore, MII oocytes and their subsequent IVF outcome were considered as the in vivo matured (PCOS-IVO) group. The data showed that supplementation of IVM medium with 50% hBM-MSC-CM significantly increased cytoplasmic and nuclear maturation of the GVs (P < 0.001), and also fertilization and two-cell rate (P < 0.001) and blastocyst formation (P < 0.01) of in vitro matured oocytes from mice with PCOS. Overall, higher oocyte maturation and fertilization outcome in PCOS-CM50 group proposed that enrichment of IVM medium with hBM-MSC-CM could be considered as a promising approach to improve IVM of PCOS oocytes.

Abstract
STUDY QUESTION What is the impact of adenosine monophosphate-activated protein kinase (AMPK) activation on blastocyst formation, gene expression, and tight junction formation and function? SUMMARY ANSWER AMPK activity must be tightly controlled for normal preimplantation development and blastocyst formation to occur. WHAT IS KNOWN ALREADY AMPK isoforms are detectable in oocytes, cumulus cells and preimplantation embryos. Cultured embryos are subject to many stresses that can activate AMPK. STUDY DESIGN, SIZE, DURATION Two primary experiments were carried out to determine the effect of AICAR treatment on embryo development and maintenance of the blastocoel cavity. Embryos were recovered from superovulated mice. First, 2-cell embryos were treated with a concentration series (0-2000 μM) of AICAR for 48 h until blastocyst formation would normally occur. In the second experiment, expanded mouse blastocysts were treated for 9 h with 1000 μM AICAR. PARTICIPANTS/MATERIALS, SETTING, METHODS Outcomes measured included development to the blastocyst stage, cell number, blastocyst volume, AMPK phosphorylation, Cdx2 and blastocyst formation gene family expression (mRNAs and protein measured using quantitative RT-PCR, immunoblotting, immunofluorescence), tight junction function (FITC dextran dye uptake assay), and blastocyst ATP levels. The reversibility of AICAR treatment was assessed using Compound C (CC), a well-known inhibitor of AMPK, alone or in combination with AICAR. MAIN RESULTS AND THE ROLE OF CHANCE Prolonged treatment with AICAR from the 2-cell stage onward decreases blastocyst formation, reduces total cell number, embryo diameter, leads to loss of trophectoderm cell contacts and membrane zona occludens-1 staining, and increased nuclear condensation. Treatment with CC alone inhibited blastocyst development only at concentrations that are higher than normally used. AICAR treated embryos displayed altered mRNA and protein levels of blastocyst formation genes. Treatment of blastocysts with AICAR for 9 h induced blastocyst collapse, altered blastocyst formation gene expression, increased tight junction permeability and decreased CDX2. Treated blastocysts displayed three phenotypes: those that were unaffected by treatment, those in which treatment was reversible, and those in which effects were irreversible. LARGE SCALE DATA Not applicable. LIMITATIONS, REASONS FOR CAUTION Our study investigates the effects of AICAR treatment on early development. While AICAR does increase AMPK activity and this is demonstrated in our study, AICAR is not a natural regulator of AMPK activity and some outcomes may result from off target non-AMPK AICAR regulated events. To support our results, blastocyst developmental outcomes were confirmed with two other well-known small molecule activators of AMPK, metformin and phenformin. WIDER IMPLICATIONS OF THE FINDINGS Metformin, an AMPK activator, is widely used to treat type II diabetes and polycystic ovarian disorder (PCOS). Our results indicate that early embryonic AMPK levels must be tightly regulated to ensure normal preimplantation development. Thus, use of metformin should be carefully considered during preimplantation and early post-embryo transfer phases of fertility treatment cycles.

Abstract
OBJECTIVES To evaluate the impact of metformin on in vitro fertilization (IVF) outcomes in overweight and obese women with polycystic ovary syndrome (PCOS). METHODS This was a randomized double-blind placebo-controlled study ( ClinicalTrials.gov : NCT02910817) carried out in a University IVF Center. The study included 102 overweight and obese women (body mass index [BMI] >24 kg/m2) with PCOS who underwent their first fresh autologous IVF-embryo transfer cycle and agreed to participate in the study. The study participants were randomized into 2 groups: metformin group received metformin (1000 mg per day) at the start of controlled ovarian stimulation (COH) until the day of the pregnancy check, and placebo group received placebo tablets in the same duration. The primary outcome measure was the total number of retrieved oocytes. RESULTS Both groups were homogenous in baseline demographic characteristics. Metformin group versus the placebo group demonstrated decrease in the mean number of the retrieved oocytes (9.06 ± 4.23 vs 16.86 ± 8.3, P < .01) and similar live birth rate (LBR; 25.5% vs 17.6%, P = .34). The number of fertilized oocytes was lower in the metformin group (5.65 ± 2.66 vs 9 ± 4.55, P < .01). However, the fertilization rate was similar in both groups (62.3% vs 53.4%, P = .10). There was no difference in the implantation rate (15.7% vs 11.8%, P = .32), multiple pregnancy rate (13.4% vs 3.9%, P = .08), or miscarriage rate (23.5% vs 35.7%, P = .46). No cases of ovarian hyperstimulation syndrome (OHSS) were observed in both groups. CONCLUSION Short-term administration of metformin to overweight or obese women with PCOS undergoing IVF decreased number of the retrieved oocytes but did not improve the LBR. SYNOPSIS Metformin use could decrease the number of retrieved oocytes in overweight and obese women with polycystic ovary syndrome undergoing IVF.

Abstract
Ovarian hyperstimulation syndrome (OHSS) is a well-recognised iatrogenic complication following controlled ovarian stimulation (COS). Mild to moderate cases are mostly managed conservatively. Severe cases of OHSS can be potentially fatal. For this reason, UK clinics providing licensed fertility treatment are obliged to follow Human Fertilisation and Embryology Authority guidelines for reporting severe incidents. We present an unusually severe complication of OHSS resulting in significant morbidity. A nulligravida woman aged 25, with a 4-year history of subfertility and multiple risk factors for the development of OHSS, underwent COS. Immediately following oocyte retrieval, the patient developed symptoms of early-onset severe OHSS. The subsequent clinical deterioration of the patient precipitated multiple organ failure, including renal and hepatic dysfunction. Despite supportive management in an intensive care unit, the patient required transfer to a tertiary liver centre for specialist treatment. OHSS is a preventable complication; therefore, such an uncommon presentation of the syndrome provides important clinical lessons to be discussed.

Abstract
INTRODUCTION Polycystic ovary syndrome (PCOS) is a common cause of female infertility affecting multiple aspects of a women's health. AREAS COVERED The aim of this review is to summarize the existing evidence on the treatment of PCOS patients and to examine the actual available therapies to overcome the problem of infertility and improve the outcome of pregnancy. We analyse different treatment strategies such as lifestyle modification, bariatric surgery, insulin sensitizing agents, inositol, clomiphene citrate (CC), aromatase inhibitors, gonadotrophins, laparoscopic ovarian drilling, and assisted reproductive techniques (ART). EXPERT COMMENTARY Lifestyle modification is the best initial management for obese PCOS patients seeking pregnancy and insulin sensitizing agents seem to have an important role in treating insulin resistance. Up to now, CC maintains a central role in the induction of ovulation and it has been confirmed as the first-line treatment; the use of gonadotrophins is considered the second-line in CC resistant patients; laparoscopic ovarian drilling is an alternative to gonadotrophins in patients who need laparoscopy for another reason. However, in anovulatory patients, ART represents the only possible alternative to obtain pregnancy. Larger and well-designed studies are needed to clarify the best way to improve the outcome of pregnancy in PCOS women.

Abstract
PURPOSE OF REVIEW Severe ovarian hyperstimulation syndrome (OHSS) is an iatrogenic condition that affects 1% of women that undergo treatment with assisted reproductive technology. The review aims to summarize recent evidence on pathophysiology, treatment, and prevention of OHSS. RECENT FINDINGS The pathophysiology is still not completely understood; however, vascular endothelial growth factor is likely to be an important mediator. Human chorionic gonadotropin was previously thought to be necessary for OHSS to occur; however, recent case reports have proven otherwise. The contribution of an attenuated anti-Mullerian hormone signalling pathway and CD11c + HLA-DR + dendritic cells and associated interleukins has been explored recently as contributors to pathogenesis.Treatment is largely supportive and is based mainly on consensus statements rather than evidence. Therefore, it is important to prevent this condition by identifying women at risk, allowing the clinician to implement preventive strategies, including the use of GnRH antagonist cycles with agonist triggers. SUMMARY More research is required to elucidate the pathophysiology behind the condition. Clinicians should employ strategies to prevent OHSS.

Abstract
Background Paracrine disruption of growth factors in women with polycystic ovarian syndrome (PCOS) results in production of low quality oocyte, especially following ovulation induction. The aim of this study was to investigate the effects of metformin (MET), N-acetylcysteine (NAC) and their combination on the hormonal levels and expression profile of GDF-9, BMP-15 and c-kit, as hallmarks of oocyte quality, in PCOS patients. MATERIALS AND METHODS This prospective randomized, double-blind, placebo controlled trial aims to study the effects of MET, NAC and their combination (MET+NAC) on expression of GDF-9, BMP-15 and c-kit mRNA in oocytes [10 at the germinal vesicle (GV) stage, 10 at the MI stage, and 10 at the MII stage from per group] derived following ovulation induction in PCOS. Treatment was carried out for six weeks, starting on the third day of previous cycle until oocyte aspiration. The expression of GDF9, BMP15 and c-kit were determined by quantitative real time polymerase chain reaction (RT-qPCR) and western blot analysis. Data were analyzed with one-way ANOVA. RESULTS The follicular fluid (FF) level of c-kit protein significantly decreased in the NAC group compared to the other groups. Significant correlations were observed between the FF soluble c-kit protein with FF volume, androstenedione and estradiol. The GDF-9 expression in unfertilized mature oocytes were significantly higher in the NAC group compared to the other groups (P<0.001). Similar difference was not observed between the MET, NAC+MET and control groups. The c-kit expression in unfertilized mature oocytes were significantly lower in the NAC group compared to the other groups (P<0.001). Similar difference was not observed between the MET, NAC+MET and control groups (Registration number: IRCT201204159476N1). CONCLUSION We concluded that NAC can improve the quality of oocytes in PCOS.

Abstract
AIM The aim of this study is to investigate the effect of metformin and/or OC added to the treatment of PCOS patients at our clinic on IVF outcome. MATERIALS AND METHODS This study is a retrospective study that assesses the data of PCOS patients who received IVF between 2005 and 2015 at a private IVF center. The study included 496 PCOS cases aged between 24 and 40. Participants diagnosed with PCOS were divided into 4 groups according to the use of metformin and OC prior to the IVF cycle: 11.1% were in the metformin group, 31.3% in the OC group, 14.9% in the Metformin + OC group, and 42.7% in the control group. RESULTS No difference was found in the total gonadotropin dose and duration of stimulation between the groups. Clinical pregnancy rates and implantation rates were similar in all groups, although the numbers of oocytes, mature oocytes, fertilized oocytes, and transferred embryos were lower in the treatment groups received metformin compared to the OC group and control group. There was no significant difference in the presence of OHSS and the singleton and multiple pregnancies between the four groups. CONCLUSION The present study established no positive role of metformin and OC use in increasing the treatment success in IVF/ICSI cycles in PCOS patients. It would be appropriate to limit the use of these agents with special indications such as decreasing insulin resistance or synchronizing follicular cohort.

Abstract
OBJECTIVES To identify, appraise and summarize the current evidence regarding the efficacy of strategies aimed at improving assisted reproductive techniques in women with polycystic ovary syndrome (PCOS). METHODS A comprehensive literature search of the standard medical databases was performed. The last electronic search was run in July 2015. The primary outcome measures were live birth/ongoing pregnancy and ovarian hyperstimulation syndrome (OHSS). The secondary outcome measures were clinical pregnancy and miscarriage. RESULTS We screened 1021 records and completely assessed 173, finally including 66 studies in the quantitative analysis. Many different interventions were assessed, however the overall quality of the studies was low. We observed moderate-quality evidence that there is no clinically relevant difference in live birth/ongoing pregnancy rates (relative risk (RR), 0.95 (95% CI, 0.84-1.08)), or clinical pregnancy (RR, 1.02 (95% CI, 0.91-1.15)) when comparing antagonist and agonist protocols for ovarian stimulation. Additionally, we found low-quality evidence that metformin improves live birth/ongoing pregnancy (RR, 1.28 (95% CI, 1.01-1.63)) and clinical pregnancy rates (RR, 1.26 (95% CI, 1.04-1.53)) when compared with placebo or no intervention. We further found low-quality evidence that there is no clinically relevant difference in live birth/ongoing pregnancy rates (RR, 1.03 (95% CI, 0.80-1.34)) and clinical pregnancy rates (RR, 0.99 (95% CI, 0.81-1.22)) when comparing human menopausal gonadotropin for inducing ovulation and artificial preparation with estradiol valerate for endometrial preparation for frozen embryo transfer (FET). Low-quality evidence suggests that mannitol compared with no intervention (RR, 0.54 (95% CI, 0.39-0.77)) and antagonist protocols compared with agonist protocols (RR, 0.63 (95% CI, 0.49-0.80)) reduce rates of OHSS. CONCLUSION There is low- to moderate-quality evidence suggesting that antagonist protocols are preferable to agonist ones, because they reduce the incidence of OHSS without interfering with clinical pregnancy and live birth for women with PCOS. Additionally there is low-quality evidence pointing to a benefit of metformin supplementation on clinical pregnancy and live birth; and that ovulation induction and administration of estradiol seem to be equally effective for endometrial preparation before FET for women with PCOS. For all other interventions, the evidence is of very low quality, not allowing any meaningful conclusions to be drawn. Estrategias para mejorar el resultado de la reproducción asistida en mujeres con síndrome de ovario poliquístico: revisión sistemática y metaanálisis RESUMEN OBJETIVOS: Identificar, evaluar y resumir la evidencia actual sobre la eficacia de las estrategias para mejorar las técnicas de reproducción asistida en mujeres con síndrome de ovario poliquístico (SOP). MÉTODOS: Se realizó una búsqueda exhaustiva de literatura en las bases de datos médicas estándar. La última búsqueda electrónica se realizó en julio de 2015. Las medidas de resultado primarias fueron los nacimientos vivos/embarazos en curso y el síndrome de hiperestimulación ovárica (SHO). Las medidas de resultado secundarias fueron el embarazo confirmado ecográficamente y el aborto. RESULTADOS Se cribaron 1021 registros, de los que se evaluaron por completo 173, para finalmente incluir 66 estudios en el análisis cuantitativo. Aunque se evaluaron muchas intervenciones diferentes, en general la calidad de los estudios fue baja. Se observó evidencia de calidad moderada de que no hay diferencias relevantes clínicamente en las tasas de nacimientos vivos/embarazos en curso (riesgo relativo (RR): 0,95 (IC 95%, 0,84-1,08)), o de embarazos confirmados ecográficamente (RR: 1,02 (IC 95%, 0,91-1,15)), cuando se comparan los protocolos de antagonistas y agonistas para la estimulación ovárica. Además, se encontró evidencia de baja calidad en que la metformina mejora las tasas de nacimientos vivos/embarazos en curso (RR: 1,28 (IC 95%, 1,01-1,63)) y de embarazos confirmados ecográficamente (RR: 1,26 (IC 95%, 1,04-1,53)) en comparación con un placebo o la no intervención. Se encontró también evidencia de baja calidad en que no hay diferencias relevantes clínicamente en las tasas de nacimientos vivos/embarazos en curso (RR: 1,03 (IC 95%, 0,80-1,34)) y las tasas de embarazos confirmados ecográficamente (RR: 0,99 (IC 95%, 0.81-1,22)) al comparar la gonadotropina menopáusica humana para la inducción de la ovulación y la preparación artificial con el valerato de estradiol para preparar el endometrio para la transferencia de embriones congelados (TEC). La baja calidad de la evidencia sugiere que el manitol, en comparación con la no intervención (RR: 0,54 (IC 95%, 0,39-0,77)), y los protocolos de antagonistas, en comparación con los protocolos de agonistas (RR: 0,63 (IC 95%, 0,49-0,80)), reducen las tasas de SHO. CONCLUSIÓN: Hay evidencia de calidad baja a moderada que sugiere que los protocolos de antagonistas son preferibles a los de agonistas, ya que reducen la tasa de SHO sin interferir con el embarazo confirmado ecográficamente y los nacimientos vivos en las mujeres con SOP. Además, existe evidencia de baja calidad que indica un beneficio del uso de metformina como aporte suplementario en embarazos confirmados ecográficamente y en nacimientos vivos; y que la inducción de la ovulación y la administración de estradiol parecen ser igualmente eficaces para la preparación del endometrio antes de la TEC en mujeres con SOP. Para el resto de procedimientos, la evidencia es de muy baja calidad, y por ello no permite extraer conclusiones importantes.

A short course of metformin does not reduce OHSS in a GnRH antagonist cycle for women with PCOS undergoing IVF: a randomised placebo-controlled trial. Hum Reprod 2016; 31:2756-2764. [PMID: 27816925 DOI: 10.1093/humrep/dew268] [Citation(s) in RCA: 26] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2016] [Revised: 08/23/2016] [Accepted: 09/17/2016] [Indexed: 11/12/2022] Open
Abstract
STUDY QUESTION Does 'metformin' reduce the incidence of ovarian hyperstimulation syndrome (OHSS) for women with polycystic ovary syndrome (PCOS) undergoing a GnRH antagonist assisted conception treatment cycle? SUMMARY ANSWER A short course of metformin does not reduce the incidence of OHSS for women with PCOS undergoing a GnRH antagonist treatment cycle. WHAT IS KNOWN ALREADY Metformin does reduce the incidence of OHSS in a GnRH-agonist treatment cycle. STUDY DESIGN, SIZE, DURATION A randomised placebo-controlled trial (RCT) using metformin or placebo. Randomisation was blinded to both patient and investigator, using a random permuted blocks method with a 50:50 allocation ratio. The study was completed over 5 years (2009-2014) with 153 randomised patients. A sample size calculation based on the incidence of OHSS was completed prospectively suggesting a minimum of 146 recruits was required for the trial with a power of 80% and a type 1 error of 0.05. PARTICIPANTS/MATERIALS, SETTING, METHODS All patients met the Rotterdam criteria for PCOS and were treated with a standard GnRH antagonist IVF/ICSI treatment cycle in a tertiary infertility clinic. The study medication was started prior to stimulation and continued to oocyte retrieval. Of the 153 patients, 77 received metformin and 76 placebo. MAIN RESULTS AND THE ROLE OF CHANCE There was no reduction in the incidence of moderate-severe OHSS (Placebo (PLA) 12.2%, metformin (MET) = 16%, 95% CI -0.08-0.16, P = 0.66). There was no difference in total gonadotrophin dose (PLA = 1200, MET = 1200, 95% CI -118.67-118.67, P = 0.75), oocytes retrieved (PLA = 15, MET = 14, 95% CI -2.37-4.37, P = 0.66) or fertilisation rate (PLA = 60.7%, MET = 53.3%, 95% CI -0.96-14.94, P = 0.07). However, using metformin resulted in a reduced clinical pregnancy rate (CPR) per cycle started (PLA = 48.7%, MET = 28.6%, 95% CI 0.04-0.35, P = 0.02) and live birth rate (PLA = 51.6%, MET = 27.6%, 95% CI 0.05-0.40, P = 0.02). Furthermore, when ethnicity was taken into account there was a significant reduction in pregnancy outcome for the South Asian population irrespective of metformin or placebo use (CPR per cycle started, White Caucasian = 44.4%, South Asian = 19.4%; 95% CI 0.06-0.39, P = 0.01). LIMITATIONS, REASONS FOR CAUTION This study was only undertaken on an infertility population with PCOS with a limited duration of study medication use. WIDER IMPLICATIONS OF THE FINDINGS This is the first adequately powered RCT to assess the impact of metformin on OHSS in a high-risk group (women with PCOS) undergoing a GnRH antagonist cycle. It does not support the empirical prescribing of metformin as an adjunct to a GnRH antagonist treatment cycle. STUDY FUNDING/COMPETING INTERESTS None. TRIAL REGISTRATION NUMBER EudraCT number 2009-010952-81. TRIAL REGISTRATION DATE 21 September 2009. DATE OF FIRST PATIENT'S ENROLMENT 30 October 2009.

The management of anovulatory infertility in women with polycystic ovary syndrome: an analysis of the evidence to support the development of global WHO guidance. Hum Reprod Update 2016; 22:687-708. [PMID: 27511809 DOI: 10.1093/humupd/dmw025] [Citation(s) in RCA: 349] [Impact Index Per Article: 43.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/07/2016] [Accepted: 06/01/2016] [Indexed: 12/23/2022] Open
Abstract
BACKGROUND Here we describe the consensus guideline methodology, summarise the evidence-based recommendations we provided to the World Health Organisation (WHO) for their consideration in the development of global guidance and present a narrative review on the management of anovulatory infertility in women with polycystic ovary syndrome (PCOS). OBJECTIVE AND RATIONALE The aim of this paper was to present an evidence base for the management of anovulatory PCOS. SEARCH METHODS The evidence to support providing recommendations involved a collaborative process for: (i) identification of priority questions and critical outcomes, (ii) retrieval of up-to-date evidence and exiting guidelines, (iii) assessment and synthesis of the evidence and (iv) the formulation of draft recommendations to be used for reaching consensus with a wide range of global stakeholders. For each draft recommendation, the methodologist evaluated the quality of the supporting evidence that was then graded as very low, low, moderate or high for consideration during consensus. OUTCOMES Evidence was synthesized and we made recommendations across the definition of PCOS including hyperandrogenism, menstrual cycle regulation and ovarian assessment. Metabolic features and the impact of ethnicity were covered. Management includes lifestyle changes, bariatric surgery, pharmacotherapy (including clomiphene citrate (CC), aromatase inhibitors, metformin and gonadotropins), as well as laparoscopic surgery. In-vitro fertilization (IVF) was considered as were the risks of ovulation induction and of pregnancy in PCOS. Approximately 80% of women who suffer from anovulatory infertility have PCOS. Lifestyle intervention is recommended first in women who are obese largely on the basis of general health benefits. Bariatric surgery can be considered where the body mass index (BMI) is ≥35 kg/m2 and lifestyle therapy has failed. Carefully conducted and monitored pharmacological ovulation induction can achieve good cumulative pregnancy rates and multiple pregnancy rates can be minimized with adherence to recommended protocols. CC should be first-line pharmacotherapy for ovulation induction and letrozole can also be used as first-line therapy. Metformin alone has limited benefits in improving live birth rates. Gonadotropins and laparoscopic surgery can be used as second-line treatment. There is no clear evidence for efficacy of acupuncture or herbal mixtures in women with PCOS. For women with PCOS who fail lifestyle and ovulation induction therapy or have additional infertility factors, IVF can be used with the safer gonadotropin releasing hormone (GnRH) antagonist protocol. If a GnRH-agonist protocol is used, metformin as an adjunct may reduce the risk of ovarian hyperstimulation syndrome. Patients should be informed of the potential side effects of ovulation induction agents and of IVF on the foetus, and of the risks of multiple pregnancy. Increased risks for the mother during pregnancy and for the child, including the exacerbating impact of obesity on adverse outcomes, should also be discussed. WIDER IMPLICATIONS This guidance generation and evidence-synthesis analysis has been conducted in a manner to be considered for global applicability for the safe administration of ovulation induction for anovulatory women with PCOS.

Abstract
Polycystic ovary syndrome is a common endocrinological problem in women of reproductive age. Polycystic ovary syndrome is a heterogenous disorder and patients may attend different clinics depending on the main complaint. The exact pathophysiology of polycystic ovary syndrome remains obscure, although there have been insights that have thrown light on this condition. Consensus on the definition of the syndrome has only been recently achieved. The management of polycystic ovary syndrome poses a challenge to the physician as responses to the different treatment regimes have proved to be inconsistent. Diet and lifestyle advice, restoration of menstrual cycle regularity, treatment of hyperandrogenism, treatment of infertility and prevention of long-term consequences form the basis of polycystic ovary syndrome management. This review aims to provide the reader with the latest evidence in the treatment of polycystic ovary syndrome, as well as focus on some of the controversies surrounding its management.

Abstract
Polycystic ovary syndrome (PCOS) affects 5-20% of women of reproductive age worldwide. The condition is characterized by hyperandrogenism, ovulatory dysfunction and polycystic ovarian morphology (PCOM) - with excessive androgen production by the ovaries being a key feature of PCOS. Metabolic dysfunction characterized by insulin resistance and compensatory hyperinsulinaemia is evident in the vast majority of affected individuals. PCOS increases the risk for type 2 diabetes mellitus, gestational diabetes and other pregnancy-related complications, venous thromboembolism, cerebrovascular and cardiovascular events and endometrial cancer. PCOS is a diagnosis of exclusion, based primarily on the presence of hyperandrogenism, ovulatory dysfunction and PCOM. Treatment should be tailored to the complaints and needs of the patient and involves targeting metabolic abnormalities through lifestyle changes, medication and potentially surgery for the prevention and management of excess weight, androgen suppression and/or blockade, endometrial protection, reproductive therapy and the detection and treatment of psychological features. This Primer summarizes the current state of knowledge regarding the epidemiology, mechanisms and pathophysiology, diagnosis, screening and prevention, management and future investigational directions of the disorder.

Abstract
Ovarian hyperstimulation syndrome (OHSS) is a severe iatrogenic complication of controlled ovarian stimulation. Randomised controlled trials (RCTs) have proven several pharmacologic interventions to be effective in OHSS prevention, but these trials have seldom compared multiple drugs. We identified randomised controlled trials (RCTs) through June 2015 by searching databases and compared 11 intervention strategies in preventing OHSS (primary outcome) and their influence on pregnancy rate (secondary outcome). A network meta-analysis was used to evaluate the relative effectiveness among treatments and to create a rank probability table. Thirty-one RCTs were identified, including 7181 participants. Five pharmacologic interventions were superior to placebo in decreasing OHSS incidence: aspirin [relative risk (RR) 0.07, 95% credible interval (CrI) 0.01-0.30, p < 0.05], intravenous (IV) calcium [RR 0.11, 95% CrI 0.02-0.54, p < 0.05], cabergoline [RR 0.17, 95% CrI 0.06-0.43, p < 0.05], metformin [RR 0.20, 95% CrI 0.07-0.59, p < 0.05] and IV hydroxyethyl starch (HES) [RR 0.26, 95% CrI 0.05-0.99, p < 0.05]. The rank probability demonstrated aspirin (Rank 1: 36%) and IV calcium (Rank 1: 35%) to be the most efficacious. Additionally, albumin might decrease the pregnancy rate when compared with placebo [RR 0.85, 95% CI 0.74-0.97, p < 0.05]. This conclusion provides a relative standard and objective reference for choosing an OHSS prophylactic agent.

Abstract
Polycystic ovary syndrome (PCOS) is associated with low-quality oocytes. The aim of the present study was to investigate the effects of metformin (MET), N-acetylcysteine (NAC) and their combination on follicular fluid parameters, oocytes and embryo quality in PCOS patients. A prospective randomised placebo-controlled pilot study on 60 Iranian women with PCOS (aged 25–35 years) undergoing intracytoplasmic sperm injection (ICSI) was designed. Women were divided into four groups (n = 15 in each): (1) an MET, administered 1500 mg day–1 MET; (2) an NAC group, administered 1800 mg day–1 NAC; (3) an NAC + MET group; and (4) a placebo group. Drugs were administered from the 3rd day of previous cycle until the day of oocyte aspiration (6 weeks treatment in total). Data were analysed by one-way ANOVA, with significance set at P < 0.05. The number of immature and abnormal oocytes decreased significantly in the NAC compared with placebo group, with a concomitant increase in the number of good-quality embryos in the NAC group (P < 0.05). Malondialdehyde levels decreased significantly in the NAC and NAC + MET groups compared with the placebo-treated group (P < 0.02). In addition, there were significant decreases in leptin levels in the NAC, MET and NAC + MET groups compared with the placebo group (P < 0.001). Insulin and LH levels were significantly lower in the MET and NAC groups compared with the placebo-treated group (P < 0.02). We concluded that NAC improves oocyte and embryo quality and could be administered as an alternative to MET.

Abstract
BACKGROUND Metformin is used among patients with polycystic ovary syndrome (PCOS), but findings for its effects on outcomes of assisted reproductive technology (ART) have been conflicting. OBJECTIVES To compare ART outcomes among women with PCOS who were and were not given metformin. SEARCH STRATEGY Databases were searched for reports published in English between 2002 and 2013, using combinations of the terms "polycystic ovary syndrome," "PCOS," "insulin-sensitizing," and "metformin." SELECTION CRITERIA Randomized controlled trials of metformin versus placebo among women with PCOS undergoing ART were included if they assessed rates of pregnancy, live birth, spontaneous abortion, multiple pregnancy, and/or ovarian hyperstimulation syndrome (OHSS). DATA COLLECTION AND ANALYSIS Data were extracted from included studies. The Mantel-Haenzel random-effects model was used for meta-analyses. MAIN RESULTS Twelve studies (1516 participants) were included. No significant differences were recorded between metformin and placebo groups for rates of pregnancy (risk ratio [RR] 1.11, 95% CI 0.92-1.33), live birth (RR 1.12, 0.92-1.36), spontaneous abortion (RR 1.00, 0.60-1.67), or multiple pregnancy (RR 0.96, 0.47-1.96). However, OHSS rate was significantly lower among patients who received metformin than among those who received placebo (RR 0.44, 0.26-0.77). CONCLUSIONS Metformin does not improve ART outcomes among patients with PCOS, but does significantly reduce their risk of OHSS.
