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.

[Bushen Culuan Formula in treatment of infertility caused by polycystic ovary syndrome].

This study aims to observe the efficacy and safety of Bushen Culuan Formula in the treatment of infertility caused by polycystic ovary syndrome(PCOS) and to explore the mechanism using metabolomics. Ninety-four patients with infertility caused by PCOS with the syndrome of kidney deficiency and blood stasis were selected and assigned into treatment and control groups(n=47). The basal body temperature(BBT) was measured, and B-ultrasonography was employed to monitor follicles, ovarian volume, endometrium, ovulation, and pregnancy. The serum levels of sex hormones including follicle-stimulating hormone(FSH), luteinizing hormone(LH), prolactin(PRL), estradiol(E_2), progestin(P), testosterone(T), free testosterone(FT), androstenedione(A2), inhibin B(INHB), and anti-Müllerian hormone(AMH) were measured. The coagulation function, traditional Chinese medicine(TCM) symptom scores, blood and urine routine, liver and kidney functions and other safety indicators were determined. Metabolomics was employed to comparatively analyze the serum metabolites of 26 patients(13 patients in each group) in the clinical study. The results showed that the total response rate and pregnancy rate of the treatment group were higher than those of the control group(P<0.001), suggesting that Bushen Culuan Formula regulated the sex hormones and ovarian function. Specifically, it reduced the levels of LH, T, FT, A2, and INHB(P<0.05 or P<0.01) and the LH/FSH ratio(P<0.05), elevated the level of P(P<0.05), promoted ovulation, increased endothelial thickness, and lowered TCM symptom scores without causing adverse reactions. A total of 24 differential metabolites were screened by metabolomics, and there were correlations between sex hormones and differential metabolites in the PCOS-induced infertility patients with kidney deficiency and blood stasis. In conclusion, Bushen Culuan Formula may regulate hormone levels through lipid and amino acid metabolism.

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.

Association Between Insulin Resistance Indices and Liver Function Parameters Among Women With Polycystic Ovary Syndrome.

OBJECTIVE: This study aimed to investigate whether polycystic ovary syndrome (PCOS) status changes the association between insulin resistance (IR) indices and liver function parameters among women. METHODS: This is a cross-sectional, population-based study. We selected 1101 subjects aged ≥20 years from participants of Tehran Lipid and Glucose Study (TLGS). All of them had known the status of PCOS, and all variables were related to the IR indices and liver function parameters. The main outcome measures were TG/HDL-C and triglyceride-glucose (TyG) and liver function parameters (hepatic steatosis index [HSI], alanine transaminase [ALT] and aspartate transaminase [AST]). RESULT: In the present study, there was no significant difference between the PCOS and the non-PCOS regarding the presence of liver function abnormalities. A model adjusted by age and BMI showed that the upper tertile of TyG index was positively associated with high AST (OR = 3.04 [95% CI: 1.20-7.68], p < 0.05), high ALT (4.76 [3.07-7.36], p < 0.05) and high HSI (8.44 [1.82-39.17], p < 0.05). Although the history of diabetes had a positive impact on elevated AST (1.66 [1.15, 2.40], p < 0.05), the third tertile of TG/HDL-C was associated with increased odds of elevated ALT (3.35 [2.21-5.06]) and HSI (6.55 [1.17-36.46]), whereas the second tertile of TG/HDL-C (OR = 2.65, CI 95%: 1.74-4.03) was also positively associated with elevated ALT. PCOS had no significant association with elevated liver function tests. CONCLUSION: The highest tertile of TyG index and the TG/HDL-C ratio as a surrogate of IR might play a role in detecting abnormalities of liver function parameters among women. However, PCOS status cannot change the association between IR and liver dysfunction.

Menstrual pattern in polycystic ovary syndrome and hypothalamic-pituitary-ovarian axis immaturity in adolescents: a systematic review and meta-analysis.

OBJECTIVE: To analyze differences in the menstrual pattern, age at menarche, and body mass index (BMI) in adolescents with Hypothalamic-Pituitary-Ovarian (HPO) axis immaturity and Polycystic Ovary Syndrome (PCOS) through a systematic review and meta-analysis. METHODS: The PubMed, EMBASE, Web of Science, Virtual Health Library, Scopus databases were searched using combinations of descriptors. Study quality was assessed using the Newcastle-Ottawa Scale. For data analysis, the results were grouped into PCOS group and NPCOS group (HPO axis immaturity). We performed a meta-analysis of raw data and the inverse variance method, employing the standardized mean difference, of the age at menarche and BMI of adolescents. RESULTS: Participants totaled 1,718 from nine selected studies. The meta-analysis showed that the PCOS group had a higher BMI than the NPCOS group (SMD 0.334; CI95% 0.073 - 0.595; p = .012). The degree of heterogeneity of the studies was approximately 40%. No significant difference in age at menarche (SMD - 0.027; CI95% -0.227 - 0.172; p = 0.790) and menstrual patterns was found, but amenorrhea was described only in adolescents with PCOS. CONCLUSIONS: The main characteristic in menstrual pattern that differentiated PCOS patients from girls with HPO axis immaturity was amenorrhea. Also, the BMI of PCOS patients was nearly one third higher than that of adolescents with HPO axis immaturity.

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.

Evaluation of muscle and bone composition and function in aging women with polycystic ovary syndrome.

OBJECTIVE: The potential effects of polycystic ovary syndrome (PCOS) on the musculoskeletal system are not well established. We examined the musculoskeletal system in women with PCOS in their late reproductive years. STUDY-DESIGN: This cross-sectional study included 34 women with PCOS and 32 control women matched for age and body mass index (BMI). MAIN OUTCOME MEASURES: Dual-energy x-ray absorptiometry (DXA) was used for body composition analysis and cross-sectional areas and fat fraction of muscles were assessed by magnetic resonance imaging-proton density fat fraction (MRI-PDFF) of the abdomen and thigh. Muscle strength was measured using an isokinetic dynamometer. RESULTS: The mean age of the PCOS group was 43 ± 3.7 years and of the control group 42.2 ± 3.5 years. Testosterone, free androgen index, and fasting insulin were higher in PCOS patients than controls (p < 0.001, p = 0.001 and p = 0.032, respectively). Patients and controls had similar values for total abdominal muscle area (TAMA), paraspinal muscle area, thigh muscle area, vertebral MRI-PDFF, thigh and paraspinal muscle MRI-PDFF. There was no difference in DXA-derived muscle and bone composition between the two groups. Body composition parameters measured by MRI and DXA were correlated with BMI and fasting insulin levels, but not with androgen levels in both groups. Subgroup analyses showed that PCOS women with obesity had higher TAMA than controls with obesity (p = 0.012). Apart than higher 60°/sec knee extensor average power in nonobese PCOS (p = 0.049), no difference in muscle mechanical function was detected between PCOS patients and controls. CONCLUSION: Musculoskeletal composition and function are similar in PCOS patients and healthy women in late reproductive years. Body composition is linked with obesity and insulin resistance rather than hyperandrogenemia.

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.

The details matter: personalized prediction of live birth after in vitro fertilization in women with polycystic ovary syndrome.

OBJECTIVE: To derive and internally validate a clinical prediction model for live birth (LB) in women with polycystic ovary syndrome (PCOS) undergoing in vitro fertilization (IVF). DESIGN: Retrospective cohort study. SETTING: Four academic reproductive endocrinology clinics. PATIENTS: A total of 207 women with PCOS confirmed using Rotterdam criteria undergoing their first fresh IVF cycle. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE: The primary outcome was cumulative LB per IVF cycle start. This included any LB that resulted from either fresh embryo transfer or any subsequent frozen embryo transfer from embryos obtained at the index oocyte retrieval. A prediction model was derived using multivariable logistic regression. Covariates considered for inclusion in the prediction model included demographic characteristics, medical history, and prior fertility treatment. Predicted probabilities for LB were calculated using the prediction model which included the 90% shrinkage factor for each adjusted odds ratio. RESULTS: The final model, on the basis of maximization of the area under the receiver operating characteristic curve, included age < 35 years, White race, presence of polycystic ovaries on ultrasound (polycystic ovary morphology), normal body mass index (<25 kg/m2), being metabolically healthy (no metabolic risk factors), and being a nonresponder to ovulation induction agents including letrozole and clomiphene citrate. The area under the receiver operating characteristic curve score for the model was 0.68 (95% confidence interval [CI]: 0.60, 0.77). Predicted probabilities of LB ranged from 8.1% (95% CI: 2.8, 21.5) for a woman who had no favorable predictors to 74.2% (95% CI: 59.5, 84.9) for a woman who had all favorable predictors. CONCLUSION: Our study demonstrated that, in addition to anovulation, the underlying pathophysiology and associated comorbidities alter the likelihood of a successful pregnancy in women with PCOS undergoing IVF. Further validation of this model is needed before it can serve as a tool to personalize prediction estimates for the probability of LB in women with PCOS.

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)
