Effect of polycystic ovary syndrome on the life quality of young women.

OBJECTIVE: The study evaluated the opinions of polycystic ovary syndrome on the life quality of women. METHODS: A total of 249 women with polycystic ovary syndrome participated in this descriptive study between October 2022 and July 2023 in Istanbul, Turkey. FINDINGS: Polycystic Ovary Syndrome and Quality of Life was significantly correlated with age (p=0.000) and frequent weight loss diets (p=0.000) (p<0.01). Among the Polycystic Ovary Syndrome and Quality of Life total score and polycystic ovary syndrome symptoms, those with hormone imbalance and insulin resistance had the highest mean scores, while those with menstrual irregularity and fatigue had the lowest. CONCLUSION: Advancing age changes the quality of life of women with polycystic ovary syndrome. To prevent the negative impact of polycystic ovary syndrome on women's quality of life, it is recommended that health professionals develop effective care plans utilizing available evidence.

Diagnostic value of ultrasound elastography in polycystic ovary syndrome: a systematic review and meta-analysis.

OBJECTIVE: The main purpose of this systematic review and meta-analysis was to investigate the diagnostic value of ultrasound elastography in the evaluation of polycystic ovary syndrome (PCOS). METHODS: A comprehensive and methodical investigation was carried out in the databases of PubMed, EMBASE, Cochrane, Scopus, Web of Science, and China National Knowledge Infrastructure, covering the entire duration of these databases until October 18, 2023. The primary purpose of this research was to evaluate and contrast ovarian tissue elasticity in people with and without PCOS. The elasticity of ovarian tissue was quantified using standardized mean difference (SMD). RESULTS: A total of eight studies were ultimately selected for systematic evaluation and meta-analysis. Five studies used shear wave elastography (SWE) as a diagnostic tool, and it was discovered that women with PCOS had higher levels of ovarian shear wave elasticity than their healthy counterparts. The SMD was determined to be 1.86 kilopascal (95% CI: 1.27 to 2.44). Three studies were conducted using strain elastography (SE) to compare the ovarian strain ratio of patients with PCOS to that of a healthy control group. The SMD for the PCOS group was 2.07 (95% CI: 1.79 to 2.34), which indicated that the ovarian strain ratio was significantly higher in that group. CONCLUSION: This systematic review and meta-analysis found that women with PCOS had stiffer ovarian tissue than women without the disorder. Ultrasound elastography may provide clinicians with value beyond 2D ultrasound in the diagnosis of PCOS.

Status of visfatin in female reproductive function under normal and pathological conditions: a mini review.

Adipokines are now well-known to regulate reproduction. Visfatin is an adipokine expressed in the hypothalamus, pituitary, ovary, uterus, and placenta of different species, and since it has been found to modulate the endocrine secretion of the hypothalamus, pituitary gland and ovary, it may be considered a novel regulator of female reproduction. Although the majority of the literature explored its role in ovarian regulation, visfatin has also been shown to regulate uterine remodeling, endometrial receptivity and embryo development, and its expression in the uterus is steroid dependent. Like other adipokines, visfatin expression and levels are deregulated in pathological conditions including polycystic ovary syndrome. Thus, the present mini-review focuses on the role of visfatin in female reproduction under both physiological and pathological conditions.

A Cross-Sectional Study of Glomerular Hyperfiltration in Polycystic Ovary Syndrome.

Glomerular hyperfiltration (GH) has been reported to be higher in women with polycystic ovary syndrome (PCOS) and is an independent risk factor for renal function deterioration, metabolic, and cardiovascular disease. The aim of this study was to determine GH in type A PCOS subjects and to identify whether inflammatory markers, markers of CKD, renal tubule injury markers, and complement system proteins were associated. In addition, a secondary cohort study was performed to determine if the eGFR had altered over time. In this comparative cross-sectional analysis, demographic, metabolic, and proteomic data from Caucasian women aged 18-40 years from a PCOS Biobank (137 with PCOS, 97 controls) was analyzed. Slow Off-rate Modified Aptamer (SOMA)-scan plasma protein measurement was undertaken for inflammatory proteins, serum markers of chronic kidney disease (CKD), tubular renal injury markers, and complement system proteins. A total of 44.5% of the PCOS cohort had GH (eGFR ≥ 126 mL/min/1.73 m2 (n = 55)), and 12% (n = 17) eGFR ≥ 142 mL/min/1.73 m2 (super-GH(SGH)). PCOS-GH women were younger and had lower creatinine and urea versus PCOS-nonGH. C-reactive protein (CRP), white cell count (WCC), and systolic blood pressure (SBP) were higher in PCOS versus controls, but CRP correlated only with PCOS-SGH alone. Complement protein changes were seen between controls and PCOS-nonGH, and decay-accelerator factor (DAF) was decreased between PCOS-nonGH and PCOS-GSGH (p < 0.05). CRP correlated with eGFR in the PCOS-SGH group, but not with other inflammatory or complement parameters. Cystatin-c (a marker of CKD) was reduced between PCOS-nonGH and PCOS-GSGH (p < 0.05). No differences in tubular renal injury markers were found. A secondary cohort notes review of the biobank subjects 8.2-9.6 years later showed a reduction in eGFR: controls -6.4 ± 12.6 mL/min/1.73 m2 (-5.3 ± 11.5%; decrease 0.65%/year); PCOS-nonGH -11.3 ± 13.7 mL/min/1.73 m2 (-9.7 ± 12.2%; p < 0.05, decrease 1%/year); PCOS-GH (eGFR 126-140 mL/min/17.3 m2) -27.1 ± 12.8 mL/min/1.73 m2 (-19.1 ± 8.7%; p < 0.0001, decrease 2%/year); PCOS-SGH (eGFR ≥ 142 mL/min/17.3 m2) -33.7 ± 8.9 mL/min/17.3 m2 (-22.8 ± 6.0%; p < 0.0001, decrease 3.5%/year); PCOS-nonGH eGFR versus PCOS-GH and PCOS-SGH, p < 0.001; no difference PCOS-GH versus PCOS-SGH. GH was associated with PCOS and did not appear mediated through tubular renal injury; however, cystatin-c and DAF were decreased, and CRP correlated positively with PCOS-SGH, suggesting inflammation may be involved at higher GH. There were progressive eGFR decrements for PCOS-nonGH, PCOS-GH, and PCOS-SGH in the follow-up period which, in the presence of additional factors affecting renal function, may be clinically important in the development of CKD in PCOS.

A comprehensive review of the new FIGO classification of ovulatory disorders.

BACKGROUND: The World Health Organization (WHO) system for the classification of disorders of ovulation was produced 50 years ago and, by international consensus, has been updated by the International Federation of Gynecology and Obstetrics (FIGO). OBJECTIVE AND RATIONALE: This review outlines in detail each component of the FIGO HyPO-P (hypothalamic, pituitary, ovarian, PCOS) classification with a concise description of each cause, and thereby provides a systematic method for diagnosis and management. SEARCH METHODS: We searched the published articles in the PubMed database in the English-language literature until October 2022, containing the keywords ovulatory disorders; ovulatory dysfunction; anovulation, and each subheading in the FIGO HyPO-P classification. We did not include abstracts or conference proceedings because the data are usually difficult to assess. OUTCOMES: We present the most comprehensive review of all disorders of ovulation, published systematically according to the logical FIGO classification. WIDER IMPLICATIONS: Improving the diagnosis of an individual's ovulatory dysfunction will significantly impact clinical practice by enabling healthcare practitioners to make a precise diagnosis and plan appropriate management.

Cellular senescence in the pathogenesis of ovarian dysfunction.

The follicular microenvironment is crucial for normal ovarian function, and intra-ovarian factors, in coordination with gonadotropins, contribute to its regulation. Recent research has revealed that the accumulation of senescent cells worsens the adverse environment of various tissues and plays critical roles in chronological aging and various pathological conditions. Cellular senescence involves cell-cycle arrest, a senescence-associated secretory phenotype (SASP), macromolecular damage, and dysmetabolism. In this review, I summarize the latest knowledge regarding the role of cellular senescence in pathological conditions in the ovary, in the context of reproduction. Specifically, cellular senescence is known to impair follicular and oocyte health in cisplatin- and cyclophosphamide-induced primary ovarian insufficiency and to contribute to the pathogenesis of polycystic ovary syndrome (PCOS). In addition, cellular senescence is induced during the decline in ovarian reserve that is associated with chronological aging, endometriosis, psychological stress, and obesity, but it remains unclear whether it plays a causative role in these conditions. Finally, I discuss the potential for use of cellular senescence as a novel therapeutic target. The modification of SASP using a senomorphic and/or the elimination of senescent cells using a senolytic represent promising therapeutic strategies. Further elucidation of the role of cellular senescence in the effects of various insults on ovarian reserve, including chronological aging, as well as in pathogenesis of ovarian pathologies, including PCOS, may facilitate a new era of reproductive medicine.

Sexual function in women with polycystic ovary syndrome: a systematic review and meta-analysis.

BACKGROUND: Polycystic ovary syndrome (PCOS) is a common and distressing endocrine disorder associated with lower quality of life, subfertility, diabetes, cardiovascular disease, depression, anxiety, and eating disorders. PCOS characteristics, its comorbidities, and its treatment can potentially influence sexual function. However, studies on sexual function in women with PCOS are limited and contradictory. OBJECTIVE AND RATIONALE: The aim was to perform a systematic review of the published literature on sexual function in women with PCOS and assess the quality of the research and certainty of outcomes, to inform the 2023 International Guidelines for the Assessment and Management of PCOS. SEARCH METHODS: Eight electronic databases were searched until 1 June 2023. Studies reporting on sexual function using validated sexuality questionnaires or visual analogue scales (VAS) in PCOS populations were included. Random-effects models were used for meta-analysis comparing PCOS and non-PCOS groups with Hedges' g as the standardized mean difference. Study quality and certainty of outcomes were assessed by risk of bias assessments and the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) method according to Cochrane. Funnel plots were visually inspected for publication bias. OUTCOMES: There were 32 articles included, of which 28 used validated questionnaires and four used VAS. Pooled Female Sexual Function Index (FSFI) scores in random-effects models showed worse sexual function across most subdomains in women with PCOS, including arousal (Hedges's g [Hg] [95% CI] = -0.35 [-0.53, -0.17], I2 = 82%, P < 0.001), lubrication (Hg [95% CI] = -0.54 [-0.79, -0.30], I2 = 90%, P < 0.001), orgasm (Hg [95% CI] = -0.37 [-0.56, -0.19], I2 = 83%, P < 0.001), and pain (Hg [95% CI] = -0.36 [-0.59, -0.13] I2 = 90%, P < 0.001), as well as total sexual function (Hg [95% CI] = -0.75 [-1.37, -0.12], I2 = 98%, P = 0.02) and sexual satisfaction (Hg [95% CI] = -0.31 [-0.45, -0.18], I2 = 68%, P < 0.001). Sensitivity and subgroup analyses based on fertility status and body mass index (BMI) did not alter the direction or significance of the results. Meta-analysis on the VAS studies demonstrated the negative impact of excess body hair on sexuality, lower sexual attractiveness, and lower sexual satisfaction in women with PCOS compared to controls, with no differences in the perceived importance of a satisfying sex life. No studies assessed sexual distress. GRADE assessments showed low certainty across all outcomes. WIDER IMPLICATIONS: Psychosexual function appears to be impaired in those with PCOS, but there is a lack of evidence on the related distress scores, which are required to meet the criteria for psychosexual dysfunction. Health care professionals should discuss sexual function and distress and be aware of the multifactorial influences on sexual function in PCOS. Future research needs to assess both psychosexual function and distress to aid in understanding the degree of psychosexual dysfunction in PCOS. Finally, more diverse populations (e.g. non-heterosexual and more ethnically diverse groups) should be included in future studies and the efficacy of treatments for sexual dysfunction should also be assessed (e.g. lifestyle and pharmacological interventions).

Increased body mass index is negatively associated with ovarian reserve as measured by anti-Müllerian hormone in patients with polycystic ovarian syndrome.

Anti-Müllerian hormone (AMH) is commonly used as a marker of ovarian reserve. Although obesity is associated with decreased fertility, the relationship between body mass index (BMI) and AMH remains uncertain, hindering the accurate interpretation of AMH. We sought to assess the relationship between serum AMH and BMI in patients with and without polycystic ovarian syndrome (PCOS). This study analysed 500 patients at a single centre between 2020 and 2021. Patients were divided into cohorts: those with BMI <40 kg/m2 and those with BMI >40 kg/m2. Patients with and without PCOS were included. Chi-square tests, Fisher's exact tests, multiple linear regression analysis and independent t-tests were performed as appropriate. In the general study population, serum AMH was not significantly different in the BMI >40 kg/m2 group compared to the BMI <40 kg/m2 group (4.3 ± 5.6 vs. 4.3 ± 5.6, p = .35). Patient ages between these two groups differed, with an average age of 35.4 ± 5.4 years in the BMI <40 kg/m2 group and 33.7 ± 5.4 years in the BMI <40 kg/m2 group (p = .031). Our multivariate regression analysis, which adjusted for age, demonstrated a significant interaction effect between BMI and PCOS diagnosis, indicating that the relationship between BMI and AMH is dependent on PCOS status (ß = -.03, 95% confidence interval [CI]: -0.05, 0.00, p = .044). In patients without PCOS, we found a non-significant relationship between AMH and BMI (ß = .00, 95% CI -0.01, 0.01, p = .7); however, in patients with PCOS, AMH significantly decreased as BMI increased (ß = -.03, 95% CI -0.06, 0.00, p = .034). BMI has an inverse association with AMH levels in patients with PCOS, indicating a need for future research to determine if that interaction represents a clinically significant negative effect on reproductive function.

Effect of High Fat Diet on Disease Development of Polycystic Ovary Syndrome and Lifestyle Intervention Strategies.

Polycystic ovary syndrome (PCOS) is a prevalent endocrine and metabolic disorder that affects premenopausal women. The etiology of PCOS is multifaceted, involving various genetic and epigenetic factors, hypothalamic-pituitary-ovarian dysfunction, androgen excess, insulin resistance, and adipose-related mechanisms. High-fat diets (HFDs) has been linked to the development of metabolic disorders and weight gain, exacerbating obesity and impairing the function of the hypothalamic-pituitary-ovarian axis. This results in increased insulin resistance, hyperinsulinemia, and the release of inflammatory adipokines, leading to heightened fat synthesis and reduced fat breakdown, thereby worsening the metabolic and reproductive consequences of PCOS. Effective management of PCOS requires lifestyle interventions such as dietary modifications, weight loss, physical activity, and psychological well-being, as well as medical or surgical interventions in some cases. This article systematically examines the pathological basis of PCOS and the influence of HFDs on its development, with the aim of raising awareness of the connection between diet and reproductive health, providing a robust approach to lifestyle interventions, and serving as a reference for the development of targeted drug treatments.

Effects of gut microbiota on omega-3-mediated ovary and metabolic benefits in polycystic ovary syndrome mice.

BACKGROUND: Polycystic ovary syndrome (PCOS) is a common reproductive endocrine disorder that frequently exhibits low-grade inflammation, pro-oxidant activity, and gut dysbiosis. PCOS has become one of the leading causes of female infertility worldwide. Recently, omega-3 polyunsaturated fatty acids (PUFAs) have been proven to benefit metabolic disorders in PCOS patients. However, its roles in the regulation of metabolic and endocrinal balances in PCOS pathophysiology are not clear. In the present study, we aimed to explore how omega-3 PUFAs alleviate ovarian dysfunction and insulin resistance in mice with dehydroepiandrosterone (DHEA)-induced PCOS by modulating the gut microbiota. METHODS: We induced PCOS in female mice by injecting them with DHEA and then treated them with omega-3 PUFAs. 16S ribosomal DNA (rDNA) amplicon sequencing, fecal microbiota transplantation (FMT) and antibiotic treatment were used to evaluate the role of microbiota in the regulation of ovarian functions and insulin resistance (IR) by omega-3 PUFAs. To further investigate the mechanism of gut microbiota on omega-3-mediated ovarian and metabolic protective effects, inflammatory and oxidative stress markers in ovaries and thermogenic markers in subcutaneous and brown adipose tissues were investigated. RESULTS: We found that oral supplementation with omega-3 PUFAs ameliorates the PCOS phenotype. 16S rDNA analysis revealed that omega-3 PUFA treatment increased the abundance of beneficial bacteria in the gut, thereby alleviating DHEA-induced gut dysbiosis. Antibiotic treatment and FMT experiments further demonstrated that the mechanisms underlying omega-3 benefits likely involve direct effects on the ovary to inhibit inflammatory cytokines such as IL-1ß, TNF-α and IL-18. In addition, the gut microbiota played a key role in the improvement of adipose tissue morphology and function by decreasing multilocular cells and thermogenic markers such as Ucp1, Pgc1a, Cited and Cox8b within the subcutaneous adipose tissues. CONCLUSION: These findings indicate that omega-3 PUFAs ameliorate androgen-induced gut microbiota dysbiosis. The gut microbiota plays a key role in the regulation of omega-3-mediated IR protective effects in polycystic ovary syndrome mice. Moreover, omega-3 PUFA-regulated improvements in the ovarian dysfunction associated with PCOS likely involve direct effects on the ovary to inhibit inflammation. Our findings suggest that omega-3 supplementation may be a promising therapeutic approach for the treatment of PCOS by modulating gut microbiota and alleviating ovarian dysfunction and insulin resistance.

Introduction: Polycystic ovary syndrome is the most common endocrinopathy affecting women in the reproductive stage. Much research has been done regarding its pathophysiology and diagnostic criteria. However, there is evidence that women who suffer from the syndrome have greater negative effects in their quality of life. The subject has not been amply approached in general and there are no studies on the subject in Cuba. Objective: To identify the scientific evidence that broadens knowledge about the effect of polycystic ovary syndrome on quality of life. Methods: A bibliographic review was carried out on the quality of life in women diagnosed with polycystic ovary syndrome. The search was performed in the electronic databases Google Scholar, Pubmed central and SCIELO Regional, which were accessed through the Google web search engine. Full articles related to observational studies, prospective studies, review articles, systematic reviews and meta-analyses, published mainly between 2000 and 2020, were reviewed. Conclusions: The present review highlights that PCOS is a condition that, due to the variety of clinical manifestations that characterize it, leads to a deterioration in the quality of life of women who suffer from it. A therapeutic intervention in each of them is beneficial to improve physical and psychological well-being and as a result, quality of life(AU)

La función sexual y su relación con los factores psicológicos en las mujeres con el síndrome de ovario poliquístico / Sexual function and its relationship to psychological factors in women with polycystic ovary syndrome

Introducción: El síndrome de ovario poliquístico tiene un notable impacto en la vida de las personas que lo padecen, siendo las áreas psicológica y sexual frecuentemente afectadas. Objetivos: Realizar una revisión bibliográfica sobre la función sexual y su relación con factores psicológicos en mujeres con síndrome de ovario poliquístico. Métodos: Se revisaron las bases de datos Google Scholar, Pubmed Central y SciELO Regional por intermedio del buscador web de Google. Algunos de los aspectos tratados en el artículo fueron los factores psicológicos, las hormonas sexuales y la función sexual, la imagen corporal y el síndrome de ovario poliquístico, y la función sexual y el síndrome de ovario poliquístico. Conclusiones: Los aspectos más estudiados del síndrome de ovario poliquístico han estado relacionados con la conceptualización y fisiopatología de la enfermedad, y las manifestaciones reproductivas y metabólicas. Otros aspectos igualmente importantes como los psicosociales y sexuales han sido muy escasamente abordados y los datos disponibles son contradictorios. Se requieren investigaciones de corte psicosocial para profundizar en las particularidades de la vida psicoemocional y sexual de esta población. Aún existe un campo novedoso poco explorado y permanecen vacíos de información en torno a la sexualidad que por su impacto influyen en el bienestar psicológico y la calidad de vida(AU)

Introduction: Polycystic ovary syndrome has a notable impact on the lives of those who suffer from it, with the psychological and sexual areas frequently affected. Objective: To carry out a literature review on sexual function and its relationship with psychological factors in women with polycystic ovary syndrome. Methods: Google Scholar, Pubmed Central and SciELO Regional databases were reviewed through the Google web search engine. Some of the aspects covered in the article were psychological factors, sex hormones and sexual function, body image and polycystic ovary syndrome, and sexual function and polycystic ovary syndrome. Conclusions: The reviewed literature allows affirming that in the Cuban and international context the most studied aspects of polycystic ovary syndrome have been related to the conceptualization and physiopathology of the disease, and its reproductive and metabolic manifestations. Other equally important aspects such as psychosocial and sexual aspects have been very scarcely broached and the available information is contradictory. Psychosocial research is needed to delve deeper into the particularities of the psychoemotional and sexual life of this population. There is still a novel field that has not been sufficiently explored and there are still gaps in the information on sexuality that, due to their impact, influence the psychological well-being and the patients' quality of life(AU)

Fisiopatología del síndrome de ovario poliquístico / Pathophysiology of polycystic ovary syndrome

Introducción: En la génesis del síndrome de ovario poliquístico intervienen múltiples factores sistémicos y locales que tienen una relación multidireccional sobre los que persisten muchas cuestiones aún sin dilucidar y cierta confusión e incertidumbre. Objetivo: Describir el enfoque actual sobre las causas y los mecanismos involucrados en el origen y desarrollo del síndrome de ovario poliquístico. Métodos: Se realizó una revisión bibliográfica tipo estado del arte. Se revisaron alrededor de 250 artículos, que se obtuvieron de las bases PubMed, Medline, SciELO y Google Académico. Se describen los factores y las vías que se proponen para explicar la etiopatogenia y fisiopatología de alteraciones genéticas, ambientales, endocrinas y metabólicas asociadas al síndrome y su expresión clínica. Conclusiones: La fisiopatología del síndrome de ovario poliquístico es compleja. Muchos aspectos permanecen sin esclarecerse, pero se tiene cada vez más conocimiento que aporta luz a los enigmas que aún persisten y a la comprensión de fenómenos previamente desconocidos. Existe el convencimiento creciente de que la alteración central es a nivel ovárico, que el síndrome es heterogéneo en todos sus elementos y que conocer la gran diversidad de factores y mecanismos que intervienen en su etiología y patogenia es fundamental no sólo desde lo científico, sino también por su utilidad práctica(AU)

Introduction: Multiple systemic and local factors are involved in the genesis of polycystic ovary syndrome that have a multidirectional relationship about which many there are questions yet to be clarified and some confusion and uncertainty persist. Objective: To describe the current approach to the causes and mechanisms involved in the origin and development of polycystic ovary syndrome. Methods: A state-of-the-art literature review was performed. The factors and pathways proposed to explain the etiopathogenesis and pathophysiology of genetic, environmental, endocrine and metabolic alterations associated with the syndrome and its clinical expression are described. Conclusions: The pathophysiology of polycystic ovary syndrome is complex. Many aspects remain unclear, but there is increasing knowledge that sheds light on the enigmas that still persist and on the understanding of previously unknown phenomena. There is a growing conviction that the central alteration is at the ovarian level, that the syndrome is heterogeneous in all its elements and that knowledge of the great diversity of factors and mechanisms involved is fundamental, not only from the scientific point of view but also for its practical utility(AU)

Female sexual behavior is disrupted in a preclinical mouse model of PCOS via an attenuated hypothalamic nitric oxide pathway.

Women with polycystic ovary syndrome (PCOS) frequently experience decreased sexual arousal, desire, and sexual satisfaction. While the hypothalamus is known to regulate sexual behavior, the specific neuronal pathways affected in patients with PCOS are not known. To dissect the underlying neural circuitry, we capitalized on a robust preclinical animal model that reliably recapitulates all cardinal PCOS features. We discovered that female mice prenatally treated with anti-Müllerian hormone (PAMH) display impaired sexual behavior and sexual partner preference over the reproductive age. Blunted female sexual behavior was associated with increased sexual rejection and independent of sex steroid hormone status. Structurally, sexual dysfunction was associated with a substantial loss of neuronal nitric oxide synthase (nNOS)-expressing neurons in the ventromedial nucleus of the hypothalamus (VMH) and other areas of hypothalamic nuclei involved in social behaviors. Using in vivo chemogenetic manipulation, we show that nNOSVMH neurons are required for the display of normal sexual behavior in female mice and that pharmacological replenishment of nitric oxide restores normal sexual performance in PAMH mice. Our data provide a framework to investigate facets of hypothalamic nNOS neuron biology with implications for sexual disturbances in PCOS.

Effects of Different Ovulation Induction Regimens on Sex Hormone Levels and Serum CTRP3 and CTRP15 Levels in Patients with Polycystic Ovary Syndrome (PCOS).

Objective: A retrospective cohort study aimed to explore the effects of different ovulation induction regimens on the levels of sex hormones and serum C1q/TNF-related protein-3 (CTRP3) and C1q/TNF-related protein-15 (CTRP15) in patients with PCOS. Methods: A total of 100 patients with PCOS treated in the department of gynecology and obstetrics from February 2019 to April 2021 in our hospital were enrolled. The patients were arbitrarily assigned into control group and study group. The treatment effect, pregnancy rate, ovulation rate, follicle size, thickness of endometrium, number of mature follicles and ovulation, serum levels of follicle stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2), testosterone (T), serum CTRP3, CTRP15 and menstrual score were compared. Results: There exhibited no statistical difference in baseline clinical data between the two kinds of patients. The therapeutic effects were compared, the effective rate was 98.00% in the study group, 13 cases in the control group, 20 cases in the effective group and 7 cases in the control group, and the effective rate was 86.00%. The effective rate in the study group was higher (P <0.05). The size of follicles and the thickness of endometrium in the two groups were compared before and after intervention. There exhibited no significant difference in the size of follicles and the thickness of endometrium before and after intervention (P >0.05). The size of follicles and the thickness of endometrium in the study group were significantly higher (P <0.05). The size of follicles and the thickness of endometrium in the study group were significantly higher (P <0.05). There exhibited no significant difference in the number of mature follicles and ovulation before and after intervention (P >0.05). After intervention, the number of mature follicles and ovulation in the two groups increased. The number of mature follicles and ovulation in the study group were (4.76 ± 0.90) and (4.48 ± 0.73), respectively, which were higher compared to the control group (2.45 ± 0.86) and (2.82 ± 0.84), respectively (P <0.05). The levels of serum LH, FSH, E2 and T were not significantly different before and after intervention. After the intervention of different ways of ovulation induction, the levels of serum LH, FSH, E2 and T in the two groups continued to decrease, and the levels of the above sex hormones in the study group were significantly lower (P <0.05). The menstrual score and the levels of serum CTRP3 and CTRP15 were compared before and after intervention. After intervention, the menstrual score of patients in both groups decreased, and the menstrual score of the study group was lower. In addition, the levels of serum CTRP3 and CTRP15 in the two groups decreased after intervention. Compared with the control group, the levels of CTRP3 and CTRP15 in the study group were lower after intervention (P <0.05). The ovulation rate and pregnancy rate of the two groups were compared. In the study group, there were 45 ovulation cases, the ovulation rate was 90.00% (45/50), the pregnancy rate was 33 cases, the pregnancy rate was 66.00% (33/50), and the ovulation rate in the control group was 31 cases, the ovulation rate was 62.00% (31/50), the pregnancy rate was 20 cases, and the pregnancy rate was 40.00% (20/50). The ovulation rate and pregnancy rate in the study group were higher (P <0.05). Conclusion: Different ovulation induction regimens have different effects on the levels of sex hormones and serum CTRP3 and CTRP15 in patients with PCOS. Long-acting follicular phase regimens can effectively promote the therapeutic effect of patients and increase the ovulation rate and pregnancy rate. In addition, it can also reduce the levels of serum LH, follicle stimulating FSH, E2 and testosterone T, and help to promote the levels of serum CTRP3 and CTRP15, which is worth popularizing and applying in clinic.

A personalized medicine approach to ovulation induction/ovarian stimulation: development of a predictive model and online calculator from level-I evidence.

OBJECTIVE: To estimate the probability of clinical or multiple pregnancy during ovulation induction (OI)/ovarian stimulation (OS). DESIGN: Secondary analysis of two multicenter randomized clinical trials (combined). SETTING: Multicenter. PATIENTS: A total of 750 women with polycystic ovary syndrome and 900 women with unexplained infertility. INTERVENTIONS: Ovulation induction/OS with either timed intercourse (polycystic ovary syndrome) or intrauterine insemination. MAIN OUTCOME MEASURES: Clinical and multiple pregnancy rates/cycle, cumulative pregnancy rates. Age, body mass index, parity, diagnosis, medication, markers of ovarian reserve, and ovarian response were considered in multivariable regression models for clinical, multiple, and cumulative pregnancy rates. Receiver operating characteristic curves were created for clinical and multiple pregnancy rates. RESULTS: Younger patient and partner age, treatment type, lower body mass index, and medication dose were all associated with clinical pregnancy. Variables associated with multiple pregnancy included the abovementioned variables (except age), in addition to diagnosis, parity, higher antral follicle count, antimüllerian hormone levels, and ovarian response. Gonadotropin use was associated with multiple pregnancy, with progressively increasing odds ratios (cycles 1-4). Receiver operating characteristic curves indicated the model's predictive power to be fair for clinical pregnancy (areas under the curve [95% confidence interval {CI}]: 0.78 [0.75-0.81] for cycle 1 and 0.70 [0.64-0.75] for cycle 4) and good-to-excellent for multiple pregnancy (areas under the curve [95% CI]: 0.78 [0.72-0.84] for cycle 1 and 0.86 [0.78-0.93] for cycle 4). Partner age, lower medication dose, parity, antimüllerian hormone levels, and diagnosis were associated with cumulative pregnancy rates. CONCLUSIONS: Using the majority of the factors known to predict the outcome of OI/OS cycles, we constructed an easy-to-use formula that may predict individualized chances of clinical and multiple pregnancy for commonly used fertility treatments (https://pregnancyprediction.medicine.yale.edu/CalDirect.html).

Basic aspects of endometrial receptivity in PCOS patients.

Polycystic Ovarian Syndrome (PCOS) is an endocrine disorder commonly affecting the reproductive capacity of women leading to infertility. PCOS-related infertility is majorly due to anovulation; however, it is not the only cause. The defective endometrium causing recurrent miscarriage and implantation failure can also be accountable for infertility in PCOS women. The unusual levels of hormones and their receptors in the PCOS endometrium have a hostile effect during WOI, making the microenvironment unfavorable for embryo implantation. To date, many studies have been performed to determine the role of candidate genes in endometrial receptivity but very limited data is available using whole genome approach. This review aims at summarizing the existing studies on the basic aspects of endometrial receptivity in PCOS. The review focuses on aberrant levels of hormones and their receptors in the endometrium, affecting the receptivity. Additionally, it explores the novel approach reviewing the effect on treatment options administered for ovulation induction in PCOS on their endometrial receptivity. Overall, this review will help us to understand the molecular milieu in PCOS endometrium and its effect on the receptivity potential. However, to have a thorough understanding of the mechanistic approach of hormonal imbalance in PCOS on endometrial receptivity, there is a need to give more weightage to genome-wide studies in the future. The current review will further guide us to formulate future studies using whole genome technologies for the assessment of endometrial receptivity in different cohorts of PCOS women, which may have future diagnostic implementations.

The effect of Myo-Inositol supplement on molecular regulation of folliculogenesis, steroidogenesis, and assisted reproductive technique outcomes in patients with polycystic ovarian syndrome.

RESEARCH QUESTION: The mechanism of Myo-Inositol, as an adjuvant, on key signaling pathways related to oocyte maturation, fertilization rate, and embryo quality as well as ovarian steroidogenesis in cumulus cells of PCOS patients, is still unclear. DESIGN: Infertile patients who were candidates for ART cycles were divided into three groups (n = 30 in each group), including group 1: PCOS patients only receiving folic acid, group 2: PCOS patients receiving daily Myo-Inositol combined with folic acid, and a control group (group 3): normal ovulatory women without PCOS receiving only folic acid from 1 month prior to IVF cycle until the day of ovum pick up. During the ART procedure, oocytes maturation, fertilization rate, and embryo quality were assessed. The gene expressions of FSHR, LHR, CYP11A1, CYP19A1, 3ß-HSD2, and StAR were also analyzed using qRT-PCR. Western blot analysis was performed for the evaluation of AKT, ERK, CREB, and AMPK phosphorylation. RESULT: Despite equal number of retrieved oocytes, the percentages of MII oocytes, fertilization rate, and embryo quality were found to be significantly higher in group 2 due to the administration of inofolic. The expressions of all the studied genes were significantly higher in the cumulus cells of group 1 compared to the group 2. Higher phosphorylation of ERK1/2 was found in the groups 2 and 3 compared to the group 1. On the other hand, p-Akt has significantly decreased in the group 2 compared to the group 1. CONCLUSION: Our study provides new insight into the molecular mechanism underlying the positive effect of Myo-Inositol on intrinsic ovarian defects in PCOS, steroidogenesis, oocyte maturation, fertilization rate, and embryo quality.

High-Intensity Interval Training in Polycystic Ovary Syndrome: A Two-Center, Three-Armed Randomized Controlled Trial.

PURPOSE: Exercise training is recommended to improve cardiometabolic health and fertility in women with polycystic ovary syndrome (PCOS), yet there are few randomized controlled trials on the effects of different exercise protocols on clinical reproductive outcomes. Our aim was to determine the effect of high-intensity interval training (HIT) on menstrual frequency, as a proxy of reproductive function, in women with PCOS. METHODS: The IMPROV-IT study was a two-center randomized controlled trial undertaken in Norway and Australia. Women with PCOS were eligible for inclusion. After stratification for body mass index <27 or ≥27 kg·m-2 and study center, participants were randomly allocated (1:1:1) to high-volume HIT (HV-HIT), low-volume HIT (LV-HIT), or a control group. Measurements were assessed at baseline, after the 16-wk exercise intervention, and at 12-month follow-up. The primary outcome was menstrual frequency after 12 months. Secondary outcomes included markers of cardiometabolic and reproductive health, quality of life, and adherence to and enjoyment of HIT. RESULTS: We randomly allocated 64 participants to the HV-HIT (n = 20), LV-HIT (n = 21), or control group (n = 23). There were no differences in menstrual frequency at 12 months between the LV-HIT and control groups (frequency ratio, 1.02; 95% confidence interval [CI], 0.73-1.42), the HV-HIT and control groups (frequency ratio, 0.93; 95% CI, 0.67-1.29), or the LV-HIT and HV-HIT groups (frequency ratio, 1.09; 95% CI, 0.77-1.56). Menstrual frequency increased in all groups from baseline to 12 months. More participants became pregnant in the LV-HIT group (n = 5) than in the control group (n = 0, P = 0.02). CONCLUSIONS: A semisupervised HIT intervention did not increase menstrual frequency in women with PCOS.Clinical Trial Registration Number:ClinicalTrials.gov (NCT02419482).

Diacerein ameliorates induced polycystic ovary in female rats via modulation of inflammasome/caspase1/IL1ß and Bax/Bcl2 pathways.

Polycystic ovary syndrome (PCOS) is a very common gynecological disease during childbearing period and markedly affects female fertility. Until now, there are no studies evaluating the possible curative effect of diacerein (DIA) in induced PCOS. For the first time, we aimed in current model to study the effect of DIA (50 mg/kg/day) orally for 3 weeks on experimentally induced PCOS by letrozole (1 mg/kg/day) for 3 weeks. We measured rats' body weight changes, levels of serum insulin, anti-Müllerian hormone (AMH), testosterone, inflammasome, caspase1, and total anti-oxidant capacity (TAC). Moreover, we measured ovarian tissue parameters as malondialdehyde (MDA), interleukin 1ß (IL1ß), real-time polymerase chain reaction (rt-PCR) of Bcl2-associated X protein (Bax), and interleukin 10 (IL10) gene expression changes. Furthermore, histopathological features and anti-apoptotic marker B cell lymphoma 2 (Bcl2) immunoexpression changes were evaluated. Our results showed that letrozole markedly induced PCOS as manifested by significant increase in serum testosterone, insulin, AMH, rats' body weights, ovarian tissue MDA, IL1ß, inflammasome, and caspase1 but decrease of serum TAC. In addition, gene expression of Bax increased but IL10 gene expression decreased. Ovaries showed the typical histopathological changes of PCOS with no immunoexpression of Bcl2. DIA was greatly able to ameliorate letrozole-induced PCOS changes in rats mainly via prevention of IL1ß, and improving metabolic disturbances, and its anti-apoptotic, anti-oxidant, and anti-inflammatory effects with further regulation of inflammasome/caspase1/IL1ß and Bax/Bcl2 pathways.
