JOURNAL OF PHARMACY AND BIOALLIED SCIENCES 2024; 16:S83-S86. [PMID: 38595559 PMCID: PMC11000949 DOI: 10.4103/jpbs.jpbs_553_23] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2023] [Revised: 08/29/2023] [Accepted: 09/21/2023] [Indexed: 04/11/2024] Open
Abstract
Objective The purpose of this systematic review and meta-analysis was to determine whether there is a connection between polycystic ovarian syndrome (PCOS)-affected women's levels of the anti-Mullerian hormone (AMH) and certain cardiometabolic indicators. Materials and Methods To find pertinent recent research published between 2017 and 2023, a thorough search was done in PubMed. Studies were included if they looked into the relationship between PCOS-related women's AMH levels and cardiometabolic markers. To determine pooled effect estimates, data from the included studies were examined using random-effects models. Results Five papers were included in the meta-analysis since they satisfied the inclusion requirements. The meta-analysis found substantial positive relationships between AMH levels and markers of insulin resistance, fasting blood sugar levels, and dyslipidemia measures such as total cholesterol (SMD: 0.68, 95% confidence interval: 0.34-1.00, P < 0.001). Conclusion This systematic review and meta-analysis show that AMH levels in PCOS-affected women significantly positively correlate with markers of insulin resistance, fasting glucose levels, and dyslipidemia parameters. These findings imply that the pathogenesis of the cardiometabolic abnormalities seen in PCOS may include AMH. AMH may be used as a biomarker to estimate the cardiometabolic risk in PCOS-affected women, but more studies are required to determine its clinical applicability.

Abstract
OBJECTIVE In this narrative review, we discuss the current evidence as well as the knowledge gaps concerning assisted reproductive technology (ART) indications, protocols, and results in the presence of polycystic ovary syndrome (PCOS). METHODS An electronic literature search was performed for English-language publications in the last decade in databases such as PubMed, Medline, the Web of Sciences, Embase, and Scopus. RESULTS We found evidence that ovarian steroidogenesis and folliculogenesis are deeply altered by PCOS; however, the oocyte quality and pregnancy rates after ART are not affected. Patients with PCOS are more sensitive to the action of exogenous gonadotropins and more likely to develop ovarian hyperstimulation syndrome. This risk can be mitigated by the adoption of the gonadotropin-releasing hormone antagonist protocols for pituitary blockade and ovarian stimulation, along with frozen embryo transfer, without compromising the odds of achieving a live birth. Pregnancy complications, such as miscarriage, gestational diabetes, preeclampsia, and very preterm birth, are more frequent in the presence of PCOS, requiring more intense prenatal care. It remains uncertain whether weight reduction or insulin sensitizers used before ART are beneficial for the treatment outcomes. CONCLUSION Although PCOS is not a drawback for ART treatments, the patients need special care to avoid complications. More in-depth studies are needed to uncover the mechanisms of follicular growth, gamete maturation, and endometrial differentiation during ART procedures in the presence of PCOS.

Serum antimüllerian hormone concentrations in female cats. Relation with ovarian remnant syndrome, ovarian cysts and gonadectomy status. Theriogenology 2023; 200:106-113. [PMID: 36805247 DOI: 10.1016/j.theriogenology.2023.02.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2022] [Revised: 01/30/2023] [Accepted: 02/10/2023] [Indexed: 02/12/2023]
Abstract
The aim of this study was to reveal (1) the determination of the serum antimüllerian hormone concentrations in cats with ovarian remnant syndrome and ovarian cyst, (2) the effectiveness of the serum antimüllerian hormone concentrations in detecting gonadectomy status, and (3) ovarian expression of the antimüllerian hormone in the ovarian cysts and ovarian remnant tissue. For this purpose, a total of 31 domestic cats older than 1 year, including ORS (n = 9), OC (n = 3), spayed (n = 8), and intact (n = 11), were used in the study. Serum and intrafollicular AMH concentrations were determined by the electrochemiluminescence immunoassay, and expression of the AMH was determined by the immunohistochemical method. The serum AMH concentration in the ORS group was 1.49 ± 1.24 ng/ml (0.10-3.63 ng/ml) whereas it was 1.78 ± 0.92 ng/ml (0.8-2.63 ng/ml) in the OC group. AMH concentration in the intrafollicular fluid was determined as 0.023 ng/ml in a cat with an ovarian cyst. While the serum AMH concentration was below 0.01 ng/ml in spayed cats, it was 5.80 ± 3.30 ng/ml (1.88-11.86 ng/ml) in the intact cats. There was a significant difference between the spayed and intact groups in terms of serum AMH concentration (p < 0.05). Moreover, in cats with ovarian cyst and ovarian remnant syndrome, no difference was found between the groups in terms of serum AMH concentration (p > 0.05). No difference was found between the ovarian remnant syndrome and intact cats in terms of serum AMH concentration (p > 0.05). In immunohistochemical staining, ovarian cysts were found to be negative for AMH while a moderate (+2) AMH positivity was observed in other follicles. Furthermore, in cats with ovarian remnant syndrome, severe (+3) AMH positivity was observed. As a result, it was determined that gonadectomy status can be accurately diagnosed by the AMH measurement. Ovarian remnant syndrome cannot be diagnosed accurately by AMH measurement. In addition, it was found that AMH did not seem to play a role in the pathogenesis of ovarian cysts in cats.

Abstract
PURPOSE OF REVIEW The aim of this review is to understand how anti-Müllerian hormone (AMH) contributes to ovulatory dysfunction in polycystic ovarian syndrome (PCOS). RECENT FINDINGS In the last few years, new findings have emerged on AMH and its role on the central nervous system causing ovulatory dysfunction. SUMMARY Anovulation is a prominent feature of PCOS. Women with anovulatory PCOS have higher AMH levels than in ovulatory PCOS. Higher levels of AMH may contribute to the pathophysiology of PCOS through central and peripheral actions. Once universal standardization is achieved to measure serum AMH, the benefits would be significant in diagnosing women with PCOS.

Abstract
AbstractPolycystic ovary syndrome (PCOS) is the most common gynecological endocrine disorders affecting up to 10% of all females in their reproductive age, and its cause of onset is still elusive. A spectrum of recent research reflected diverse associations between increased plasma level of anti-Mullerian hormone (AMH) and different clinical features of PCOS. Since AMH levels reflect the pool of growing follicles that potentially can ovulate, it can be stated that serum AMH levels can be used to assess the “functional ovarian reserve,” rather mentioning it as the “ovarian reserve.” AMH also appears to be a premier endocrine parameter for the assessment of atrophied ovarian follicular pool in response to age of individuals. AMH hinders the follicular development as well as the follicular recruitment and ultimately resulting in follicular arrest which is the key pathophysiologic condition for the onset of PCOS. Furthermore, FSH-induced aromatase activity remains inhibited by AMH that aids emergence of other associated clinical signs of PCOS, such as excess androgen, followed by insulin resistance among the PCOS individuals. Given the versatile association of AMH with PCOS and scarcity in literature explaining the underling mechanisms how AMH relates with PCOS, this review article will discuss the roles of AMH in the pathogenesis of PCOS which may introduce a new era in treatment approach of PCOS.

Abstract
STUDY QUESTION What biological processes are linked to the signaling of the energy sensor 5'-AMP-activated protein kinase (AMPK) in mouse and human granulosa cells (GCs)? SUMMARY ANSWER The lack of α1AMPK in GCs impacted cell cycle, adhesion, lipid metabolism and induced a hyperandrogenic response. WHAT IS KNOWN ALREADY AMPK is expressed in the ovarian follicle, and its activation by pharmacological medications, such as metformin, inhibits the production of steroids. Polycystic ovary syndrome (PCOS) is responsible for infertility in approximately 5-20% of women of childbearing age and possible treatments include reducing body weight, improving lifestyle and the administration of a combination of drugs to improve insulin resistance, such as metformin. STUDY DESIGN, SIZE, DURATION AMPK signaling was evaluated by analyzing differential gene expression in immortalized human granulosa cells (KGNs) with and without silencing α1AMPK using CRISPR/Cas9. In vivo studies included the use of a α1AMPK knock-out mouse model to evaluate the role of α1AMPK in folliculogenesis and fertility. Expression of α1AMPK was evaluated in primary human granulosa-luteal cells retrieved from women undergoing IVF with and without a lean PCOS phenotype (i.e. BMI: 18-25 kg/m2). PARTICIPANTS/MATERIALS, SETTING, METHODS α1AMPK was disrupted in KGN cells and a transgenic mouse model. Cell viability, proliferation and metabolism were evaluated. Androgen production was evaluated by analyzing protein levels of relevant enzymes in the steroid pathway by western blots, and steroid levels obtained from in vitro and in vivo models by mass spectrometry. Differential gene expression in human GC was obtained by RNA sequencing. Analysis of in vivo murine folliculogenesis was performed by histology and immunochemistry, including evaluation of the anti-Müllerian hormone (AMH) marker. The α1AMPK gene expression was evaluated by quantitative RT-PCR in primary GCs obtained from women with the lean PCOS phenotype (n = 8) and without PCOS (n = 9). MAIN RESULTS AND THE ROLE OF CHANCE Silencing of α1AMPK in KGN increased cell proliferation (P < 0.05 versus control, n = 4), promoted the use of fatty acids over glucose, and induced a hyperandrogenic response resulting from upregulation of two of the enzymes involved in steroid production, namely 3β-hydroxysteroid dehydrogenase (3βHSD) and P450 side-chain cleavage enzyme (P450scc) (P < 0.05, n = 3). Female mice deficient in α1AMPK had a 30% decrease in their ovulation rate (P < 0.05, n = 7) and litter size, a hyperandrogenic response (P < 0.05, n = 7) with higher levels of 3βHSD and p450scc levels in the ovaries, and an increase in the population of antral follicles (P < 0.01, n = 10) compared to controls. Primary GCs from lean women with PCOS had lower α1AMPK mRNA expression levels than the control group (P < 0.05, n = 8-9). LARGE SCALE DATA The FastQ files and metadata were submitted to the European Nucleotide Archive (ENA) at EMBL-EBI under accession number PRJEB46048. LIMITATIONS, REASONS FOR CAUTION The human KGN is a not fully differentiated, transformed cell line. As such, to confirm the role of AMPK in GC and the PCOS phenotype, this model was compared to two others: an α1AMPK transgenic mouse model and primary differentiated granulosa-lutein cells from non-obese women undergoing IVF (with and without PCOS). A clear limitation is the small number of patients with PCOS utilized in this study and that the collection of human GCs was performed after hormonal stimulation. WIDER IMPLICATIONS OF THE FINDINGS Our results reveal that AMPK is directly involved in steroid production in human GCs. In addition, AMPK signaling was associated with other processes frequently reported as dysfunctional in PCOS models, such as cell adhesion, lipid metabolism and inflammation. Silencing of α1AMPK in KGN promoted folliculogenesis, with increases in AMH. Evaluating the expression of the α1AMPK subunit could be considered as a marker of interest in infertility cases related to hormonal imbalances and metabolic disorders, including PCOS.

Abstract
In this study, the stereo-pathological effect of metformin and N-acetyl cysteine is evaluated on the uterus and ovary of polycystic ovary syndrome (PCOS) mice. 96 mature females (8-weekold, weight of 20–30 gr) BALB/c mice were classified into 6 groups including the control group (n= 16), letrozole-induced PCOS group (n=16), PCOS + metformin (n=16), PCOS+NAC (n=16) and a separate control group for NAC (n=16). Another PCOS group was maintained for a month to make sure that features remain till the end of the study. Testosterone level, vaginal cytology and stereological evaluations were assessed. Vaginal cytology in letrozole-receiving mice showed a diestrus phase continuity. Testosterone level, body weight, uterine weight, endometrial volume, myometrial volume, gland volume, stromal volume, epithelial volume, vessel volume, daughter and conglomerate glands, endometrial thickness, and myometrial thickness exhibited an increasing trend in the uterus of PCOS mice. While normal gland and vessel length decreased in the PCOS group. Ovarian volume, corticomedullary volume, primary follicles, secondary follicles, and ovarian cysts were increased in PCOS ovaries. While corpus luteum, primordial, graafian, and atretic follicles showed a decline in the PCOS group. NAC and metformin, however, managed to restore the condition to normal. Given the prevalence of PCOS and its impact on fertility, the use of noninvasive methods is of crucial significance. NAC can control and treat pathological parameters and help as a harmless drug in the treatment of women with PCOS.

Abstract
Background Polycystic ovary syndrome (PCOS) is one of the most common causes of anovulatory infertility. Chinese herbal medicine (CHM) has many advantages in treating PCOS. We conducted a retrospective cohort study to investigate the effects of CHM (Bu-Shen-Tian-Jing Formula, BSTJF) on the outcomes of IVF in Chinese patients with PCOS and the potential underlying mechanism. Methods A total of 111 patients with PCOS who undergone IVF between November 2009 and July 2018 were included. Fifty-four patients received a three-month BSTJF therapy before controlled ovarian hyperstimulation, while the other 57 patients didn't. The data of the PCOS patients was collected. Anti-Müllerian hormone (AMH), growth differentiation factor-8 (GDF-8) levels in the follicular fluid were evaluated. Results BSTJF helped patients with PCOS to get more retrieved oocytes (P<0.05) and fertilized oocytes (P<0.05). The clinical cumulative pregnancy rate, live birth rate, and term delivery rate were significantly higher in the same stimulated cycle of the PCOS patients with BSTJF treatment (P<0.05). No significant differences existed between the two groups in the rate of fertilization, hospitalization rate of ovarian hyper stimulation syndrome and obstetrical or neonatal complications. BSTJF significantly decreased the AMH levels in the follicular fluids (P<0.05). Conclusion BSTJF significantly may improve the outcomes of IVF in Chinese patients with PCOS through decreasing AMH levels in follicular fluids. However, the evidence is limited due to the small sample size and the several potential bias.

Abstract
Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders leading to infertility in women affecting reproductive, endocrine and metabolic systems. Recent genomewide association studies on PCOS cohorts revealed a single nucleotide polymorphism (SNP) in the ERBB4 receptor tyrosine kinase 4 gene, but its role in ovary development or during folliculogenesis remains poorly understood. Since no genetic animal models mimicking all PCOS reproductive features are available, we conditionally deleted Erbb4 in murine granulosa cells (GCs) under the control of Amh promoter. While we have demonstrated that Erbb4 deletion displayed aberrant ovarian function by affecting the reproductive function (asynchronous oestrous cycle leading to few ovulations and subfertility) and metabolic function (obesity), their ovaries also present severe structural and functional abnormalities (impaired oocyte development). Hormone analysis revealed an up-regulation of serum luteinizing hormone, hyperandrogenism, increased production of ovarian and circulating anti-Müllerian hormone. Our data implicate that Erbb4 deletion in GCs leads to defective intercellular junctions between the GCs and oocytes, causing changes in the expression of genes regulating the local microenvironment of the follicles. In vitro culture assays reducing the level of Erbb4 via shRNAs confirm that Erbb4 is essential for regulating Amh level. In conclusion, our results indicate a functional role for Erbb4 in the ovary, especially during folliculogenesis and its reduced expression plays an important role in reproductive pathophysiology, such as PCOS development.

Abstract
STUDY QUESTION Do alterations in pro- and anti-angiogenic estrogen metabolites in follicular fluid (FF) contribute to the follicular growth arrest and anovulation associated with polycystic ovary syndrome (PCOS)? SUMMARY ANSWER FF of PCOS women with anovulation have reduced levels of pro-angiogenic estrogen metabolites (EMs) and vascular endothelial growth factor (VEGF) compared to that of fertile women with regular menstrual cycles, but exogenous gonadotropins increase the pro-angiogenic EMs and VEGF levels in PCOS women. WHAT IS KNOWN ALREADY PCOS is characterized by the arrest of follicular development that leads to chronic anovulation. Follicular arrest is generally associated with elevated plasma levels of luteinizing hormone (LH), androgens and anti-Mullerian hormone (AMH). There is also reduced angiogenesis in the follicles of PCOS women compared to those of normal cycling women. It is known that angiogenesis is a critical factor during follicular development. We and other investigators have explored the role of EMs in ovarian angiogenesis, particularly in human corpus luteum function, showing that 4-hydroxyestrone (4-OHE1) and 16-ketoestradiol (16-kE2) have pro-angiogenic effects while 2-methoxyestradiol (2-ME2) and 2-methoxyestrone (2-ME1) have anti-angiogenic effects. Additionally, 2-hydroxyestradiol (2-OHE2), which is produced in the ovary, has proliferative and pro-angiogenic properties. We hypothesized that EMs could be involved in angiogenesis necessary for ovarian follicular development in fertile women, and that dysregulation of these factors may contribute to follicular arrest in PCOS. The relationship between EMs, VEGF and AMH in the pathophysiology of follicular arrest in PCOS has not been previously studied at a follicular level in anovulatory women without ovulation induction. STUDY DESIGN, SIZE, DURATION This is a comparative experimental study of serum and FF collected from different sized follicles (antral ˂10 mm and dominant ˃16 mm) of women with and without ovarian stimulation. The study included women with regular menstrual cycles who were proven to be fertile (n = 20) and PCOS women with follicular arrest who were candidates for ovarian drilling (n = 17), as well as other patients requiring ovarian stimulation, i.e. control women undergoing IVF for male factor infertility (n = 12) and PCOS women undergoing IVF (n = 17). In vitro studies were carried out on granulosa-lutein cells (GCs) obtained from subsets of women undergoing IVF for male factor infertility (n = 6) and PCOS women undergoing IVF (n = 6). GCs were maintained in culture for up to 6 days. PARTICIPANTS/MATERIALS, SETTING, METHODS Intrafollicular estradiol, estrone and EMs concentrations were determined by high performance liquid chromatography-mass spectrometry. Testosterone in serum was measured by RIA, and LH, FSH and sex hormone-binding globulin in serum were measured with IRMA kits. AMH was determined in serum and FF by enzyme linked immunosorbant assay (ELISA). VEGF levels were measured in FF and conditioned medium by ELISA. Conditioned medium were obtained from cultured GCs. The angiogenic potential was assessed by in vitro angiogenic assays. MAIN RESULTS AND THE ROLE OF CHANCE Pro-angiogenic EMs (4-OHE1, 16-kE2 and 2-OHE2) and VEGF were lower in FF of antral follicles of PCOS women with follicular arrest compared those of fertile women with ovulatory cycles (P < 0.05). In contrast, higher concentrations of AMH were found in FF of antral follicles from PCOS women with follicular arrest compared to those of fertile women with ovulatory cycles (P < 0.05). Exogenous gonadotropins used in IVF increased pro-angiogenic EMs and VEGF production in PCOS women, reaching similar profiles compared to control women receiving gonadotropins in their IVF treatment for male factor infertility. The pro-angiogenic EM 2-OHE2 increased the angiogenic potential and VEGF levels of GCs from PCOS women compared to the basal condition (P < 0.05). These findings suggest that there is a role for pro-angiogenic EMs in the control of follicular VEGF production. LIMITATIONS, REASONS FOR CAUTION The limitations include the possibility that in vitro analysis of GCs might not reflect the in vivo mechanisms involved in the pro-angiogenic action of 2-OHE2 since GCs obtained at the time of oocyte retrieval belong to a very early stage of the luteal phase and might not be representative of GCs during follicular growth. Therefore, our findings do not conclusively rule out the possibility that other in vivo mechanisms also account for defective angiogenesis observed in PCOS. WIDER IMPLICATIONS OF THE FINDINGS The present study highlights the significance of EMs, angiogenic factors and AMH and their interaction in the pathophysiology of follicular development in PCOS. This study provides new insights into the role of pro-angiogenic factors in follicular arrest in PCOS.

Abstract
BACKGROUND The aim of this study was to define the performance characteristics of the Mindray chemiluminescence assay for anti-Müllerian hormone (AMH) detection. DESIGNS AND METHODS Intra-assay and total imprecision, analytical sensitivity, linearity, and interference were compared between the Mindray and Roche assays using pools of human serum according to Clinical and Laboratory Standards Institute protocols. Additionally, male and female reference intervals were established using serum specimens collected from otherwise healthy groups and patients with polycystic ovary syndrome (PCOS). RESULTS The intra-assay and total imprecision percent coefficients of variation for low and high AMH serum levels were 2.74%/ 3.01% and 5.41%/5.35% respectively. The limits of blank, detection, and quantitation were 0.007, 0.01, and 0.03 ng/ml, respectively. The assay displayed good linearity over the range of 0.01-23 ng/ml. The coefficient of determination (R2 ) of the Mindray versus Roche assays was 0.9713 with 411 samples with AMH concentrations ranging from 0.014 to 22.1 ng/ml. The slope and intercept of the regression equation were 0.9687 and 0.3419, respectively. There was no significant interference from triglycerides (up to 3000 mg/dl), bilirubin (up to 50 mg/dl), hemoglobin (up to 500 mg/dl), or total protein (up to 10 g/dl). Reference intervals showed the expected decrease in serum AMH levels with age in healthy women and increased levels in women with PCOS. CONCLUSION The Mindray AMH assay demonstrated acceptable analytical performance under routine conditions and is suitable for determining AMH levels in serum samples.

Abstract
RESEARCH QUESTION Is the endocrine milieu different in women with low serum anti-Müllerian hormone (AMH) concentration compared with women with high concentration? DESIGN Cohort study of 84 women (four groups) classified according to AMH concentration and age undergoing natural cycle IVF treatment. Concentrations of LH, oestradiol, testosterone, androstenedione and AMH were determined in follicular fluid (FF), associations analysed and clinical outcome parameters evaluated. RESULTS A positive correlation between serum and FF AMH concentrations was confirmed. Follicular fluid androstenedione concentration was positively correlated with serum AMH concentration (P < 0.0001, r2 = 0.197). The correlation between FF LH and FF testosterone concentration in all women was not significant (P = 0.050, r2 = 0.046); however, the correlation between FF androstenedione in women with high serum AMH concentration was significant (P = 0.032, r2 = 0.220). Follicular fluid testosterone and androstenedione were positively correlated with FF oestradiol overall and in some individual groups. The high serum AMH concentration group showed the highest FF AMH and androstenedione concentrations and lowest oestradiol-testosterone and oestradiol-androstenedione ratios. High FF AMH concentration was associated with a higher clinical pregnancy rate and high FF oestradiol concentration with a slightly better embryo quality. CONCLUSIONS Differences in the endocrine milieu in women with high serum AMH concentration seem to be caused by increased follicular LH concentration. In women with high serum AMH concentration, FF androstenedione is increased and ratios of oestradiol-testosterone and oestradiol-androstenedione are decreased, suggesting a disturbed endocrine milieu caused by reduced metabolization of FF androgens into oestrogens. In natural cycles, FF AMH concentrations are positively associated with higher clinical pregnancy rates and oestradiol concentrations with a higher embryo score.

Abstract
PURPOSE Elevated oxidative stress has been proposed as an important factor in the pathogenesis of polycystic ovary syndrome (PCOS)-related infertility. Our study was aimed at simultaneously exploring local and systemic oxidative stress in PCOS individuals and its relationship with embryo quality. METHODS We recruited 86 PCOS cases and 60 controls. Five representative oxidative stress markers, namely, total oxidant capacity (TOC), total antioxidant capacity (TAC), malonaldehyde (MDA), glutathione (GSH), and superoxide dismutase (SOD), were measured in both follicular fluid (FF) and serum. RESULTS Women with PCOS compared to normal controls had higher levels of TOC in both FF (10.13 ± 2.68 vs.7.03 ± 2.45, P < 0.001) and serum (11.76 ± 2.92 vs. 8.82 ± 2.57, P < 0.001). The oxidative stress index (OSI, the ratio of TOC to TAC) was also higher in PCOS cases. They were still significant after BMI adjustment (Padj<0.01). In addition, the serum OSI level was much higher than the FF OSI level in both groups. Correlation analysis showed that the FF and serum TOC were negatively correlated with the high-quality embryo rate on day 3 and the later blastocyst formation rate in the PCOS group (P < 0.05). The correlation coefficient was higher in FF. Moreover, as the regression analysis data showed, the FF MDA level was significantly associated with embryo quality indicators (P < 0.05). CONCLUSIONS PCOS was accompanied by elevated oxidative stress in both serum and FF. Even though serum oxidative stress was severe, the study suggested that FF oxidative stress contributed more to embryo quality, to which we should give more attention in the future.

Abstract
In recent years, the discovery of ovarian germ stem cells (OGSCs) has provided a new research direction for the treatment of female infertility. The ovarian microenvironment affects the proliferation and differentiation of OGSCs, and immune cells and related cytokines are important components of the microenvironment. However, whether improving the ovarian microenvironment can regulate the proliferation of OGSCs and remodel ovarian function has not been reported. In this study, we chelated chito-oligosaccharide (COS) with fluorescein isothiocyanate (FITC) to track the distribution of COS in the body. COS was given to mice through the best route of administration, and the changes in ovarian and immune function were detected using assays of organ index, follicle counting, serum estrogen (E2) and anti-Mullerian hormone (AMH) levels, and the expression of IL-2 and TNF-α in the ovaries. We found that COS significantly increased the organ index of the ovary and immune organs, reduced the rate of follicular atresia, increased the levels of E2 and AMH hormones, and increased the protein expression of IL-2 and TNF-α in the ovary. Then, COS and OGSCs were co-cultured to observe the combination of COS and OGSCs, and measure the survival rate of OGSCs. With increasing time, the fluorescence intensity of cells gradually increased, and the cytokines IL-2 and TNF-α significantly promoted the proliferation of OGSCs. In conclusion, COS could significantly improve the ovarian and immune function of chemotherapy model mice, and improve the survival rate of OGSCs, which provided a preliminary blueprint for further exploring the mechanism of COS in protecting ovarian function.

Abstract
Both classical androgens and 11-oxygenated androgens play important roles in polycystic ovarian syndrome (PCOS). Therefore, high-quality measurements of androgens are very important. In the present study, a highly sensitive and specific method was developed and validated for the simultaneous determination of three classical androgens and five 11-oxygenated androgens in human serum, using a high- performance liquid chromatography-differential mobility spectrometry tandem mass spectrometry (HPLC-DMS/MS/MS). Serum samples were extracted with the mixture of ethyl acetate/tert-butyl methyl ether (1/1, v/v) prior to analysis with the HPLC-DMS/MS/MS system. Stable isotopes were used as the internal standards. Separation was performed on a Poroshell SB C18 column (150 × 2.1 mm, 2.7 μm), with a differential mobility spectrometry (DMS) component, which was used to enhance the resolution. The gradient mobile phase consisted of acetonitrile and ammonium formate buffer with 0.1 % formic acid in both solvents. The sensitivity of the majority of the androgens was improved following addition of the DMS component. Under the optimal conditions, the trace amount of the target androgens in the serum was quantified accurately. The lower limit of quantification of the different analytes ranged from 0.05 to 0.2 ng/mL. The method was validated prior to its application to the assay of the clinical samples.

Abstract
CONTEXT Polycystic ovary syndrome (PCOS) is a prevalent disorder in reproductive aged women associated with a number of endocrine and metabolic complications, including increased risk of endometrial cancer. OBJECTIVE To study the effect of the characteristic increased androgen levels in PCOS on the endometrium, a novel scaffold-free multicellular endometrial organoid was established. DESIGN Human endometrial organoids were constructed using primary endometrial epithelial and stromal cells from endometrial tissues. Organoids were treated for 14 days with physiologic levels of estradiol and testosterone to mimic a normal follicular phase or PCOS hormone profiles. Organoids were harvested for immunostaining and ribonucleic acid sequencing. SETTING Academic institution. PATIENTS Endometrial tissues from 10 premenopausal women undergoing hysterectomy for benign pathologies were obtained following written consent. MAIN OUTCOME MEASURES Organoid architecture, cell specific markers, functional markers, proliferation, and gene expression were measured. RESULTS A method to generate scaffold-free endometrial organoids containing epithelial and stromal cells was established. These organoids exhibited distinct organization with epithelial cells lining the outer surface and stromal cells in the center of the organoids. Epithelial cells were polarized, organoids expressed cell type specific and functional markers, as well as androgen, estrogen, and progesterone receptors. Treatment with PCOS hormones increased cell proliferation and dysregulated genes in endometrial organoids. CONCLUSIONS A new multicellular, scaffold-free endometrial organoid system was established that resembled physiology of the native endometrium. Excess androgens in PCOS promoted cell proliferation in endometrial organoids, revealing new mechanisms of PCOS-associated with risk of endometrial neoplasia.

Abstract
The Maillard reaction is a simple but ubiquitous reaction that occurs both in vivo and ex vivo during the cooking or processing of foods under high-temperature conditions, such as baking, frying, or grilling. Glycation of proteins is a post-translational modification that forms temporary adducts, which, on further crosslinking and rearrangement, form permanent residues known as advanced glycation end products (AGEs). Cooking at high temperature results in various food products having high levels of AGEs. This review underlines the basis of AGE formation and their corresponding deleterious effects on the body. Glycated Maillard products have a direct association with the pathophysiology of some metabolic diseases, such as diabetes mellitus type 2 (DM2), acute renal failure (ARF), Alzheimer’s disease, dental health, allergies, and polycystic ovary syndrome (PCOS). The most glycated and structurally abundant protein is collagen, which acts as a marker for diabetes and aging, where decreased levels indicate reduced skin elasticity. In diabetes, high levels of AGEs are associated with carotid thickening, ischemic heart disease, uremic cardiomyopathy, and kidney failure. AGEs also mimic hormones or regulate/modify their receptor mechanisms at the DNA level. In women, a high AGE diet directly correlates with high levels of androgens, anti-Müllerian hormone, insulin, and androstenedione, promoting ovarian dysfunction and/or infertility. Vitamin D3 is well-associated with the pathogenesis of PCOS and modulates steroidogenesis. It also exhibits a protective mechanism against the harmful effects of AGEs. This review elucidates and summarizes the processing of infant formula milk and the associated health hazards. Formulated according to the nutritional requirements of the newborn as a substitute for mother’s milk, formula milk is a rich source of primary adducts, such as carboxy-methyl lysine, which render an infant prone to inflammation, dementia, food allergies, and other diseases. We therefore recommend that understanding this post-translational modification is the key to unlocking the mechanisms and physiology of various metabolic syndromes.

Anti-Müllerian hormone inhibits luteinizing hormone-induced androstenedione synthesis in porcine theca cells. Theriogenology 2019; 142:421-432. [PMID: 31711705 DOI: 10.1016/j.theriogenology.2019.10.037] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2019] [Revised: 10/30/2019] [Accepted: 10/30/2019] [Indexed: 11/28/2022]
Abstract
AMH (Anti-Müllerian Hormone) is involved in the regulation of follicle growth initiation and inhibits FSH-induced aromatase expression and estrogen production in granulosa cells. However, the function of AMH in steroidogenesis by theca cells remains unclear. The aim of this study is to investigate the role of AMH as a regulator of the basal and stimulated steroid production by pig granulosa cells (pGCs) and theca cells (pTCs). PGCs and pTCs were incubated with hormones AMH, LH (luteinizing hormone), FSH (follicle stimulating hormone), individually or in combination. The expression of CYP19A1, HSD3B1, CYP11A1, LHCGR, and CYP17A1 mRNA were evaluated by quantitative reverse transcriptase PCR. In pGCs, 10 ng/mL AMH significantly decreased the FSH-stimulated effect on FSHR and CYP19A1 expression and estradiol production. In pTCs, LH treatment significantly increased the expression of HSD3B1, CYP11A1, LHCGR, and androstenedione or progesterone production (P < 0.05). Additionally, 10 ng/mL AMH also significantly decreased the LH-stimulated effects on the expression of HSD3B1, CYP11A1, CYP17A1, LHCGR and androstenedione production. Transfection with siAMHR2-I abolished the suppressive effects of AMH on LH-induced HSD3B1 expression and androstenedione production. Taken together, these results demonstrate that AMH is involved in FSH induced estradiol production in pGCs and LH induced androstenedione production in pTCs by regulating the steroidogenesis pathway.

Abstract
Objective This study was performed to assess the predictive value of the anti-Müllerian hormone (AMH) serum level for spontaneous pregnancy in women after endometriosis surgery. Methods In total, 124 patients with suspected ovarian endometrioma planning to undergo laparoscopic ovarian cystectomy were divided into a high AMH group (AMH > 2 ng/mL) and low AMH group (AMH ≤ 2 ng/mL) according to their preoperative AMH levels. The postoperative AMH levels were also measured, and pregnancy outcomes were followed up. Results Twenty-one patients were excluded, and 52 pregnancies were registered in the remaining 103 patients diagnosed with endometriosis. The pregnancy rate was significantly greater in the high than low AMH group. Receiver operator characteristics analysis of preoperative AMH, postoperative AMH, and the AMH decline rate showed that preoperative AMH was associated with the greatest area under the curve. Kaplan–Meier curves showed that women in the high AMH group had a significantly higher cumulative pregnancy rate than those in the low AMH group. Conclusion The preoperative AMH level might be a useful marker to predict the occurrence of natural pregnancy and could be offered as part of the fertility strategy to women who desire pregnancy after endometriosis surgery.

Abstract
PURPOSE Anti-Müllerian hormone (AMH) is a useful marker of ovarian reserve. Obesity/overweight are increasing and may affect the reproductive health. Previous studies regarding the effect of body mass index (BMI) on AMH levels are discordant. Our main goal was to evaluate the influence of BMI on AMH levels in women without polycystic ovarian syndrome. METHODS Revision of medical records of 951 women who performed AMH determinations as part of their fertility workup, between 2011 and 2016. RESULTS Median AMH concentration was 1.75 [interquartile range (IQR) 2] ng/mL (12.9 pmol/mL) and median age at AMH determination was 35 (IQR 6) years. These women evidenced a median BMI of 23 (IQR 5) kg/m2. Caucasian women were more represented [889(89.3%)]. Smoking habits (present/past) were present in 359(36.1%), and 147(14.8%) harboured a history of ovarian surgery. On univariable analysis AMH was not correlated with BMI (r = 0.048/p = 0.135); the only factors influencing AMH were age (p < 0.001), ethnicity (p = 0.004), and previous ovarian surgery (p < 0.001). On multivariable analysis, age was the only variable significantly associated with AMH, evidencing a reduction of 6.2% for each additional year (p < 0.0001). Furthermore, we verified a trend suggesting an AMH reduction of 22% (p = 0.08) in black patients comparing with the caucasian ones, when controlling for the other variables. CONCLUSION We report one of the largest series evaluating the influence of BMI on AMH levels and, consequently, on ovarian reserve. BMI does not seem to affect AMH levels. The reported concerns on infertility in overweight and obese women may be related to follicular development/oocyte maturation or endometrial disorders, rather than decreased ovarian reserve.

Abstract
Women with high-AMH levels have an increased risk of ovarian hyperstimulation syndrome (OHSS). Studies have suggested that highly purified menotropin (HP-hMG) Menopur® reduces the risk. We, therefore, studied use of low-dose (112.5 IU/day) HP-hMG in ovulatory and anovulatory patients with high AMH (>32 pmol/L). The primary endpoint was the distribution of patients with appropriate, excessive, and inadequate response (5-14, ≥15, and ≤4 oocytes). Another endpoint was frequency of OHSS. Totally 115 women were included and 78 (67.8%) had an appropriate, 8 (7.0%) an excessive, and 29 (25.2%) an inadequate response. The number of oocytes was independent on AMH levels and ovulatory status but declined significantly with increasing bodyweight (R2 = 0.07, p < .01). The ongoing pregnancy rate per started cycle was 47.0%. Three (2.6%) developed OHSS, two had cancelation of the cycle and seven patients had GnRH agonist triggering to prevent OHSS. Selective use of a low dose of HP-hMG in patients with high levels of AMH provides 5-14 oocytes in more than two-thirds of the patients and is safe with low risk of OHSS. The number of aspirated oocytes was independent of AMH levels and ovulatory status, but inversely related to body weight.

Abstract
Background PCOS is a reproductive hormonal abnormality and a metabolic disorder. It is frequently associated with insulin resistance, hyperandrogenism, chronic inflammation, and oxidative stress. We aim to investigate the potential therapeutic effects of combined therapy of resveratrol and metformin on polycystic ovaries via SIRT1 and AMPK activation. Methods Wistar albino rats were divided into control and experimental (PCOS) groups. DHEA-induced PCOS rats were given resveratrol (20 mg/kg/day), metformin (300 mg/kg/day) and combined therapy. At the end of the experiment, the body and ovarian weight of rats were measured and blood samples were analyzed for FSH, LH, testosterone, AMH, TNF-α and MDA levels. Histopathological evaluation of ovaries were carried out by light and electron microscopy. SIRT1 and AMPK immunreactivity and TUNEL assay were scored. Data were statistically analyzed by SPSS programme. Results Metformin and combined treatment groups reduced the body and ovary weights compared to the PCOS group. Serum testosterone levels were significantly higher in the PCOS group than in the control group and this was reduced when PCOS was treated with all but especially resveratrol. All the treatment groups decreased LH, LH/FSH, TNF-α and tissue AMH levels which were induced in the PCOS group, whereas metformin was unable to improve the increased MDA and plasma AMH levels. Treatment with resveratrol and/or metformin ameliorated the elevated number of secondary and atretic follicles and the decreased number of Graafian follicles in the PCOS group, which indicates the effect of the treatments on the maintenance of folliculogenesis. Light and electron microscopic findings supported the analysis of follicular count. Increased number of TUNEL (+) granulosa cells in the PCOS group were reduced significantly in the treatment groups. Resveratrol and metformin increased SIRT1 and AMPK immunreactivity, respectively, compared to the PCOS group. Conclusions The results suggest that combined therapy of metformin and resveratrol may improve the weight gain, hormone profile and ovarian follicular cell architecture by inducing antioxidant and antiinflammatory systems via SIRT1 and AMPK activation in PCOS.

Abstract
BACKGROUND Overweight/obese women with polycystic ovary syndrome (PCOS) are at increased risk of subfertility and complications of pregnancy, compared with normal-weight women. To implement controlled ovarian hyperstimulation (COH), the improved efficacy of the gonadotrophin-releasing hormone antagonist (GnRH-ant) protocol has been demonstrated, as well as frozen embryo transfer (FET). OBJECTIVE This retrospective study evaluated the pregnancy outcomes after combined GnRH-ant protocol and FET in overweight/obese women with PCOS, with reference to that of normal-weight women with PCOS. METHODS Women with PCOS (n = 398) who underwent the GnRH-ant protocol for COH followed by FET, were stratified as normal-weight (BMI < 24 kg/m2) or overweight/obese (BMI ≥24 kg/m2). The outcomes of pregnancy were compared. RESULTS The overweight/obese patients had significantly lower rates of embryo implantation (47.7%), live birth (47.8%), and live births of twins (10.9%) compared with the normal-weight group (58.4%, 60.8%, and 30.0%, respectively; P = 0.006, 0.015, and 0.000), while the rate of late abortion was significantly higher (11.0% cf. 3.8%, P = 0.030). BMI was the only significant factor affecting the probability of live birth. CONCLUSION The pregnancy outcomes of overweight/obese women with PCOS after COH via the GnRH-ant protocol and FET remained at a significant deficit compared with that of normal-weight women with PCOS.
