Anti-Müllerian hormone beyond an ovarian reserve marker: the relationship with the physiology and pathology in the life-long follicle development. Front Endocrinol (Lausanne) 2023; 14:1273966. [PMID: 38027144 PMCID: PMC10657644 DOI: 10.3389/fendo.2023.1273966] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/07/2023] [Accepted: 10/16/2023] [Indexed: 12/01/2023] Open
Abstract
Anti-Müllerian hormone (AMH), an indirect indicator of the number of remaining follicles, is clinically used as a test for ovarian reserve. Typically, a decline suggests a decrease in the number of remaining follicles in relation to ovarian toxicity caused by interventions, which may implicate fertility. In contrast, serum AMH levels are elevated in patients with polycystic ovary syndrome. AMH is produced primarily in the granulosa cells of the preantral and small antral follicles. Thus it varies in association with folliculogenesis and the establishment and shrinking of the follicle cohort. Ovarian activity during the female half-life, from the embryonic period to menopause, is based on folliculogenesis and maintenance of the follicle cohort, which is influenced by developmental processes, life events, and interventions. AMH trends over a woman's lifetime are associated with in vivo follicular cohort transitions that cannot be observed directly.

The Role of Serum Anti-Mullerian Hormone Measurement in the Diagnosis of Polycystic Ovary Syndrome. Diagnostics (Basel) 2023; 13:diagnostics13050907. [PMID: 36900051 PMCID: PMC10000702 DOI: 10.3390/diagnostics13050907] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2023] [Revised: 02/18/2023] [Accepted: 02/20/2023] [Indexed: 03/06/2023] Open
Abstract
Polycystic ovary syndrome (PCOS) is a common endocrinological disorder in women with significant reproductive, metabolic, and psychological health implications. The lack of a specific diagnostic test poses challenges in making the diagnosis of PCOS, resulting in underdiagnosis and undertreatment. Anti-Mullerian hormone (AMH) synthesized by the pre-antral and small antral ovarian follicles appears to play an important role in the pathophysiology of PCOS, and serum AMH levels are often elevated in women with PCOS. The aim of this review is to inform the possibility of utilizing anti-Mullerian hormone either as a diagnostic test for PCOS or as an alternative diagnostic criterion in place of polycystic ovarian morphology, hyperandrogenism, and oligo-anovulation. Increased levels of serum AMH correlate highly with PCOS, polycystic ovarian morphology, hyperandrogenism, and oligo/amenorrhea. Additionally, serum AMH has high diagnostic accuracy as an isolated marker for PCOS or as a replacement for polycystic ovarian morphology.

Abstract
AIM The abnormal secretion of luteinizing hormone (LH) is one of the typical features of polycystic ovary syndrome (PCOS) and adopted in the diagnostic criteria of the Japan Society of Obstetrics and Gynecology (JSOG). We investigated cut-off values for LH and the LH/follicle-stimulating hormone (FSH) ratio in resent two measurement systems for the diagnosis of PCOS. METHODS Ninety-nine controls and 106 patients with PCOS were enrolled. Serum LH and FSH levels were measured using an electrochemiluminescence immunoassay (ARCHITECT) and chemiluminescence immunoassay (ECLusys). We examined the distribution of the measured levels, selected the conversion closest to the standard normal distribution in the control group, and calculated mean + 1 SD values for LH and the LH/FSH ratio as candidates. Cut-off values coincided with the medians of the candidates in the two assay systems using a regression equation. We calculated the endocrinological abnormality rate in PCOS according to the JSOG criteria by abnormal LH secretion and elevated T. RESULTS Cut-off values for LH (mIU/mL) and the LH/FSH ratio were 7.1 and 1.21, respectively, in ARCHITECT, and 9.9 and 1.51, respectively, in ECLusys. The detection rates of endocrinological abnormalities in PCOS were 72.2% and 70.6% in the nonoverweight/obese PCOS group and overweight/obese PCOS group, respectively, in ARCHITECT, and 69.4% and 73.5%, respectively, in ECLusys. CONCLUSION We obtained cut-off values of LH and the LH/FSH ratio for diagnostic criteria of JSOG criteria for PCOS, that were highly compatible between two major assay systems. These cut-off values will contribute to the diagnosis of PCOS in Japan and presumably in women of Asian ethnicities.

Abstract
Polycystic ovary syndrome (PCOS) is an endocrine disorder that causes menstrual cycle irregularities and infertility. PCOS is diagnosed based on hyperandrogenism, polycystic ovarian morphology (PCOM), and an-/oligo-ovulation. Upregulation of anti-Müllerian hormone (AMH) in the serum of women with PCOS may be another suitable alternative diagnostic criterion for PCOM. However, previous meta-analyses have reported conflicting results due to the age-dependent decline in serum AMH levels. Therefore, we performed a meta-analysis to evaluate the threshold of AMH for the diagnosis of PCOS in adolescents and women in their early twenties. Fifteen trials were included in this meta-analysis. PCOS is diagnosed with either Rotterdam criteria, NIH, or AE-PCOS. AMH levels were significantly higher in adolescents with PCOS (weighted mean difference, 3.05; 95% confidence interval: 2.09-4.01) than in the control group. The cutoff values of AMH for the diagnosis of adolescent PCOS were 6.1, 6.26, 7.03, 7.11, 7.2, and 7.25 ng/mL in the studies that reported the usefulness of AMH levels. The summary receiver operating characteristic analysis of the diagnostic accuracy demonstrated that the specificity and sensitivity were 81% and 66.3%, respectively. Our meta-analysis demonstrates that AMH may be a useful diagnostic test for adolescent PCOS and, based on the previous studies included in the meta-analysis, its cutoff value was estimated to be 6-7 ng/mL.

Abstract
AIM To determine the diagnostic accuracy of anti-Mullerian hormone (AMH) in the diagnosis of polycystic ovary syndrome (PCOS). METHODS Two independent reviewers searched the electronic databases and search engines using PubMed, Cochrane library, and Google Scholar systematically to retrieve relevant articles published from inception to September 2021. The diagnostic efficacy of AMH was computed using the random-effects model in terms of pooled sensitivity, specificity, and diagnostic odds ratio (DOR) with 95% confidence interval (CI). A meta-regression and subgroup analysis were performed to check for any source which could explain possible heterogeneity. Risk of bias assessment was conducted using the QUADAS-2 tool recommended by Cochrane Library. RESULTS This meta-analysis included a total of 41 studies involving 13 509 subjects. We observed promising pooled sensitivity 0.78 (95% CI 0.74 to 0.81), specificity 0.87 (95% CI 0.84 to 0.90), and diagnostic odds ratio (DOR) 24 (95% CI 15 to 37), for AMH in detecting PCOS and discriminatory power (summary receiver operating characteristic [SROC] curves, 0.89 [95% CI 0.86-0.92]). The most prominent bias was noted in the patient selection and index test assessment. CONCLUSIONS With the findings of this current meta-analysis, we conclude serum AMH to be a promising biomarker for the diagnosis of PCOS, however, substantial heterogeneity among studies needs individual patient data analysis in order to identify an optimal cut-off value and homogenous findings. REGISTRATION NUMBER AND GUIDELINES This meta-analysis was performed according to constructed protocol registered in the PROSPERO database with registration number CRD42021246910.

Abstract
Evolutionary and comparative approaches can yield novel insights into human adaptation and disease. Endometriosis and polycystic ovary syndrome (PCOS) each affect up to 10% of women and significantly reduce the health, fertility, and quality of life of those affected. PCOS and endometriosis have yet to be considered as related to one another, although both conditions involve alterations to prenatal testosterone levels and atypical functioning of the hypothalamic-pituitary-gonadal (HPG) axis. Here, we propose and evaluate the novel hypothesis that endometriosis and PCOS represent extreme and diametric (opposite) outcomes of variation in HPG axis development and activity, with endometriosis mediated in notable part by low prenatal and postnatal testosterone, while PCOS is mediated by high prenatal testosterone. This diametric disorder hypothesis predicts that, for characteristics shaped by the HPG axis, including hormonal profiles, reproductive physiology, life-history traits, and body morphology, women with PCOS and women with endometriosis will manifest opposite phenotypes. To evaluate these predictions, we review and synthesize existing evidence from developmental biology, endocrinology, physiology, life history, and epidemiology. The hypothesis of diametric phenotypes between endometriosis and PCOS is strongly supported across these diverse fields of research. Furthermore, the contrasts between endometriosis and PCOS in humans parallel differences among nonhuman animals in effects of low versus high prenatal testosterone on female reproductive traits. These findings suggest that PCOS and endometriosis represent maladaptive extremes of both female life-history variation and expression of sexually dimorphic female reproductive traits. The diametric disorder hypothesis for endometriosis and PCOS provides novel, unifying, proximate, and evolutionary explanations for endometriosis risk, synthesizes diverse lines of research concerning the two most common female reproductive disorders, and generates future avenues of research for improving the quality of life and health of women.

Abstract
The knowledge of polycystic ovary syndrome (PCOS) natural history is limited. Our objective was to assess the effect of aging on clinical, hormonal and sonographic ovarian PCOS features and additionally to identify parameters that impact the course of PCOS. A secondary aim was to supply additional information on the reproductive outcome in women with previously diagnosed PCOS. A longitudinal cohort study with a median follow-up of 120.9 months was conducted, and 31 Caucasian women previously diagnosed with PCOS according to the Rotterdam criteria were re-examined at a median age of 35. Clinical examinations; transvaginal ultrasound scans; and lipid, E-selectin and sex hormone assessments were performed at the beginning and at the end of the follow-up. It was observed that menstrual cycles became regular and sonographic morphology of ovaries was normalized in 55% and 49% of the participants, respectively (all p < 0.05). At the final assessment, 55% of the women no longer met the criteria for PCOS (p < 0.05). The age, follicle-stimulating hormone (FSH) and E-selectin assessed at the baseline were the most important predictors of the PCOS persistence into later years (respectively, OR = 0.84, OR = 0.39, OR = 1.08, all p < 0.05). Ninety-five percent of the patients who had ever been trying to conceive became pregnant a minimum of once. The women with persistent PCOS had worse metabolic and reproductive parameters compared to the women with resolved PCOS. Positive correlations were found between the number of miscarriages and ovarian volume, LH, androstenedione, 17-hydroxyprogesterone and an increase in E-selectin during the follow-up (R = 0.46, R = 0.59, R = 0.54, R = 0.49, R = 0.47, all p < 0.05). In conclusion, progressing from the third to the fourth decade is connected with a reduction in PCOS features, which seems to have a great impact on fertility of women with a previous diagnosis of PCOS. FSH and E-selectin, as determined at the initial PCOS diagnosis, had an impact on the disappearance of the syndrome years after.

Abstract
OBJECTIVE This systematic review and meta-analysis aimed to summarize the available evidence regarding circulating kisspeptin and anti-müllerian hormone (AMH) and the homeostasis model assessment of insulin resistance (HOMA-IR) index in adolescents and women with and without polycystic ovary syndrome (PCOS). METHOD We performed a comprehensive literature search in Medline, Embase, Cochrane, Scopus, and Web of Science for studies evaluating circulating kisspeptin levels in women with and without PCOS published until September 24th, 2020. Co-primary outcomes were the HOMA-IR index and AMH. The quality of included studies was assessed using the Newcastle-Ottawa Scale. Random-effects models were used to estimate outcomes, and effects reported as mean difference (MD) or standardized MD (SMD) and their 95 % confidence interval (CI). The systematic review and meta-analysis was registered in the International Prospective Register of Systematic Reviews (PROSPERO) as number CRD42020205030. RESULTS We evaluated 18 studies including, 1282 PCOS cases and 977 controls. Participants with PCOS were younger (MD = -2.38 years, 95 %CI -4.32 to -0.44), with higher BMI (MD = 1.16, 95 % CI 0.54-1.78), waist-to-hip ratio (MD = 0.04, 95 %CI 0.02 to 0.05), circulating kisspeptin (SMD = 1.15, 95 %CI 0.68-1.62), luteinizing hormone (SMD = 1.29, 95 %CI 0.76-1.83), AMH (SMD = 0.97, 95 %CI 0.60-1,34), total testosterone (SMD = 2.48, 95 %CI 1.73-3.23), free testosterone (SMD = 1.37, 95 %CI 0.56-2.17), and dehydroepiandrosterone sulphate (SMD = 0.72, 95 %CI 0.32-1.13) levels, and Ferriman-Gallwey score (SMD = 5.08, 95 %CI 2.76-7.39), and lower sex hormone-binding globulin level (SMD = -1.34, 95 %CI -2.15 to -0.52). Besides, participants with PCOS had higher HOMA-IR index (SMD = 0.76, 95 %CI 0.35-1.17), and circulating insulin (SMD = 0.75, 95 %CI 0.30-1.19), leptin (SMD = 2.82, 95 %CI 1.35-4.29), and triglycerides (SMD = 2.15, 95 %CI 1.08-3.23) levels than participants without the syndrome. The meta-regression did not identify significant factors influencing circulating kisspeptin. CONCLUSION Patients with PCOS showed higher kisspeptin, LH, insulin, AMH, and androgen levels and HOMA-IR index, and lower sex hormone-binding globulin levels than those without the syndrome.

Abstract
Polycystic ovary syndrome (PCOS) is the main cause of anovulatory infertility and affects women throughout their lives. The specific diagnostic method is still under investigation. In the present study, we aimed to identify the metabolic tracks of the follicular fluid and plasma samples from women with PCOS by performing Raman spectroscopy with principal component analysis and spectral classification models. Follicular fluid and plasma samples obtained from 50 healthy (non-PCOS) and 50 PCOS women were collected and measured by Raman spectroscopy. Multivariate statistical methods and different machine-learning algorithms based on the Raman spectra were established to analyze the results. The principal component analysis of the Raman spectra showed differences in the follicular fluid between the non-PCOS and PCOS groups. The stacking classification models based on the k-nearest-neighbor, random forests and extreme gradient boosting algorithms yielded a higher accuracy of 89.32% by using follicular fluid than the accuracy of 74.78% obtained with plasma samples in classifying the spectra from the two groups. In this regard, PCOS may lead to the changes of metabolic profiles that can be detected by Raman spectroscopy. As a novel, rapid and affordable method, Raman spectroscopy combined with advanced machine-learning algorithms have potential to analyze and characterize patients with PCOS.
