As a highly dynamic tissue, the endometrium is periodically shed in response to the secretion of estrogen and progesterone. After menarche, the endometrium of healthy women proliferates and differentiates under the action of steroid hormones (e.g., 17β-estradiol and progesterone) that are secreted by the ovaries to provide appropriate conditions for embryo implantation. Polycystic ovary syndrome (PCOS), a prevalent endocrine and metabolic disorder in reproductive-aged women, is usually associated with multiple cysts within the ovaries and excess levels of androgen and is characterized by hirsutism, acne, menstrual irregularity, infertility, and increased risk of insulin resistance. Multiple factors, such as anovulation, endocrine-metabolic abnormalities, and inflammation, can disrupt the endometrium in PCOS patients and can lead to endometrial hyperplasia, pregnancy complications, or even cancer. Despite many recent studies, the relationship between PCOS and abnormal endometrial function is still not fully understood. In this review, we investigate the correlation of PCOS patient endometrium with anovulation, hyperandrogenemia, insulin resistance, progesterone resistance, and inflammatory cytokines, aiming to provide a theoretical basis for the treatment of disorders caused by endometrial dysfunction in PCOS patients.

: Polycystic ovary syndrome (PCOS) is a frequent endocrine disease in women during reproductive period. It is considered a complex metabolic disorder with long-term metabolic, as well as reproductive consequences. Main pathophysiological pathways are related to the increased androgen levels and insulin resistance. Nowadays, genetic origins of PCOS are acknowledged, with numerous genes involved in the pathogenesis of hyperandrogenemia, insulin resistance, inflammation and disturbed folliculogenesis. Rotterdam diagnostic criteria are most widely accepted and four PCOS phenotypes have been recognized. Metabolic abnormalities are more common in phenotypes 1 and 2. Women with classic PCOS are more obese and typically have central type of obesity, more prevalently displaying dyslipidemia, insulin resistance and metabolic syndrome that could be associated with an increased risk of cardiovascular complications during life. Heterogeneity of phenotypes demands an individualized approach in the treatment of women with PCOS. Metabolic therapies involve a lifestyle intervention followed by the introduction of insulin sensitizers including metformin and inositols, glucagon-like peptide 1 receptor agonists (GLP-1 RA), as recently sodium glucose contransporter-2 (SGLT2) inhibitors. Addition of an insulin sensitizer to the standard infertility therapy such as CC improves ovulation and pregnancy rates. Our current review analyzes the contemporary knowledge of PCOS etiology and etiopathogenesis, its cardiometabolic risks and their outcomes, as well as therapeutic advances for women with PCOS.

Polycystic ovary syndrome (PCOS) is a common but complex endocrine disorder and is a major cause of anovulation and consequent subfertility. It is also associated with a metabolic disturbance, characterized by hyperinsulinaemia and insulin resistance that carries an increased risk of type 2 diabetes in later life. Despite its prevalence little is known about its aetiology, but there is increasing evidence for an important genetic involvement. On the basis of experimental observations in the prenatally androgenized sheep and rhesus monkey, and supported by data from human studies, we propose that the clinical and biochemical features of PCOS can arise as a consequence of genetically determined hypersecretion of androgens by the ovary during, or very likely long before, puberty. The resulting hyperandrogenism results in 'programming' of the hypothalamic-pituitary unit to favour excess LH secretion, and encourages preferential abdominal adiposity that predisposes to insulin resistance. The severity of hyperinsulinaemia and insulin resistance (which has a profound influence on the phenotype of PCOS) is further influenced by both genetic factors (such as polymorphism in the insulin gene regulatory region) and environmental factors, notably obesity. This hypothesis therefore suggests a unifying, 'linear' model to explain the aetiology of the heterogeneous phenotype.

Abstract Polycystic ovary syndrome (PCOS) is one of the most common hormonal disorders that affects between 5- 10% of women of reproductive age. It is currently considered a complex and multifactorial disease with metabolic, cardiovascular implications and represents per se an increased cancer risk. PATIENTS with PCOS routinely have menstrual disorders, hyperandrogenism, infertility and reproductive complications such as recurrent abortions, gestational diabetes, intrauterine growth restriction, pregnancy induced hypertension that give rise to underweight newborns and condition metabolic diseases to adult life and increased risk of cancer, especially breast and endometrial cancer. Insulin resistance and hyperandrogenism are the most important etiopathogenic factors in PCOS. On the other hand, subjects exposed to an adverse microenvironment in the intrauterine stage develop compensating responses to survive, a process called fetal programming. Prenatal exposure to androgens and/or insulin resistance may act as fetal programming factors and cause restriction of intrauterine growth, obesity and insulin resistance in offspring. Newborn may have an increased risk of metabolic syndrome, increased incidence of hypertensive, type 2 diabetes, heart disease and cerebrovascular disease. Prevention of these complications will be achieved if women with Polycystic Ovary Syndrome are treated appropriately throughout their lives, but especially before and during their pregnancy. Only in this way can the risk of them be reduced, representing a better quality and greater life expectancy.

Background: Polycystic ovary syndrome is a common endocrinopathy in women of reproductive age with prevalence of 6-10% which is characterized by hyper androgenic features and chronic oligo – anovulation and polycystic ovary morphology. Most women with polycystic ovary syndrome are also characterized by metabolic abnormalities like insulin resistance, hyperinsulinemia, dyslipidemia and abdominal obesity, these forming risk factors for metabolic syndrome. The objective of the study was to compare the clinical, biochemical and hormonal profile of polycystic ovary syndrome patients with and without metabolic syndrome.Methods: A comparative cross- sectional study was undertaken on 79 PCOS women diagnosed with PCOS according to Rotterdam criteria, in which the clinical data and hormonal profile of two groups of polycystic ovary syndrome women with and without metabolic syndrome was compared.Results: The mean age of 79 patients in this study group with and without metabolic syndrome was 26.17±3.18 and 25.57±3.41 years respectively. There were more patients from urban areas as compared to rural areas and maximum patients. Significantly higher number of PCOS women with metabolic syndrome had hirsutism and acanthosis nigricans than those without metabolic syndrome. Mean value of Waist circumference, systolic BP pressure, diastolic BP, S. Triglyceride and fasting glucose were higher and HDL levels were lower in women with metabolic syndrome than those without metabolic syndrome. Fasting insulin and HOMA-IR values were significantly higher in PCOS women with metabolic syndrome in comparison to those without metabolic syndrome.Conclusion: PCOS is not only is the most frequent cause of anovulation, but it is also associated with characteristic metabolic disturbances that may have important implications for the long term health. Metabolic syndrome is a cluster of endocrine disturbances, including insulin resistance, dyslipidemia, obesity, and hypertension. It is associated with a two-fold increased risk of cardiovascular disease and a five-fold increased risk of type 2 diabetes. This illustrates the importance of early detection of insulin resistance and metabolic syndrome with subsequent application of preventive measures in women with polycystic ovary syndrome.

Adverse Pregnancy

Abstract Context Polycystic ovary syndrome (PCOS) is the most common endocrinopathy of reproductive-aged women. In pregnancy, women with PCOS experience increased risk of miscarriage, gestational diabetes, preeclampsia, and extremes of fetal birth weight, and their offspring are predisposed to reproductive and cardiometabolic dysfunction in adulthood. Pregnancy complications, adverse fetal outcomes, and developmental programming of long-term health risks are known to have placental origins. These findings highlight the plausibility of placental compromise in pregnancies of women with PCOS. Evidence Synthesis A comprehensive PubMed search was performed using terms “polycystic ovary syndrome,” “placenta,” “developmental programming,” “hyperandrogenism,” “androgen excess,” “insulin resistance,” “hyperinsulinemia,” “pregnancy,” and “pregnancy complications” in both human and animal experimental models. Conclusions There is limited human placental research specific to pregnancy of women with PCOS. Gestational androgen excess and insulin resistance are two clinical hallmarks of PCOS that may contribute to placental dysfunction and underlie the higher rates of maternal–fetal complications observed in pregnancies of women with PCOS. Additional research is needed to prevent adverse maternal and developmental outcomes in women with PCOS and their offspring.

Abstract Context: Polycystic ovary syndrome (PCOS), the most common reproductive endocrine disorder of premenopausal women, is also associated with metabolic abnormalities including insulin resistance and an increased risk for diabetes mellitus. We previously mapped a PCOS susceptibility locus to chromosome 19p13.2 near the dinucleotide repeat marker D19S884. Objective: Our objective is to localize the chromosome 19p13.2 PCOS susceptibility locus and determine its impact on metabolic features of PCOS. Design: Resequencing and family-based association testing were used to examine the effect of sequence variation within 100 kb of D19S884 on the reproductive and metabolic phenotypes of PCOS. Setting: The study was conducted in an academic medical center. Subjects: Genetic analyses were performed on DNA obtained from1723 individuals in 412 families with 412 index cases and 43 affected sisters of predominantly European origin (>94%). Genotype-phenotype associations were assessed in 601 women with PCOS and 168 brothers of affected women. Results: D19S884 allele 8 (A8) within intron 55 of the fibrillin-3 (FBN3) gene showed the strongest evidence for association with PCOS of 53 variants tested (Pcorrected = 0.0037). A8 was also associated with higher levels of fasting insulin and homeostasis model assessment for insulin resistance in women with PCOS and higher fasting levels of proinsulin and proinsulin/insulin ratio in brothers. Conclusions: These findings strongly suggest that A8 of D19S884 is the chromosome 19p13.2 PCOS susceptibility locus. The association of D19S884 with markers of insulin resistance and pancreatic β-cell dysfunction suggests that the same variant contributes to the reproductive and metabolic abnormalities of PCOS in affected women and their brothers.

Polycystic ovary syndrome (PCOS) is a disease with reproductive dysfunction and abnormal endocrine metabolism. It is characterized by hyperandrogenism, insulin resistance (IR) and persistent anovulation. At present, the pathogenesis and pathological mechanism of PCOS are still unclear, and there is no unified standard for the diagnosis and treatment of PCOS locally nor abroad. It is still a famous and difficult problem to explore the pathogenesis of PCOS and seek effective prevention and treatment methods.
