BACKGROUND: Polycystic ovary syndrome (PCOS) is the most prevalent endocrinopathy in women of reproductive age. The study was commenced to assess the favorable effects of Rutin against metabolic, biochemical, histological, and androgenic aspects of polycystic ovary syndrome in rats. METHODS: Female Sprague-Dawley rats were administered letrozole (1 mg/kg) per orally (p.o) for a period of 21 days for the induction of PCOS, followed by dose of rutin (100 mg/kg and 150 mg/kg, p...

Polycystic ovary syndrome (PCOS) is the most common ovarian disorder associated with androgen excess in women, which justifies the growing interest of endocrinologists. This syndrome leads to clinical hyperandrogenism and/or a biological dysovulation and infertility. Its diagnosis is based on consensual diagnostic criteria, but which are likely to change in the near future with the rise of the interest of new markers such as AMH. Diagnostic tools of PCOS are also discussed, with emphasis on the laboratory evaluation of androgens and other potential biomarkers of ovarian and metabolic dysfunctions...

Insulin resistance (IR) plays a pivotal role in PCOS. Insulin-sensitizer agents such as metformin and inositols have been shown to improve the endocrine and metabolic aspects of PCOS. The purpose of this study is to compare their effects on the clinical and metabolic features of the women with PCOS. Fifty PCOS women with IR and/or hyperinsulinemia were randomized to treatment with metformin (1500 mg/day) or myo-inositol (4 g/day). IR was defined as HOMA-IR >2.5, while hyperinsulinemia was defined as a value of AUC for insulin after a glucose load over the cutoff of our laboratory obtained in normal women...

BACKGROUND: It is assumed that obesity adversely affects the health related quality of life (HRQOL) of women with polycystic ovary syndrome (PCOS), not only due to the excess weight, but also due to several other obesity induced metabolic and reproductive consequences. We aimed to compare the effects of excess body weight on the HRQOL between women with PCOS and controls. METHODS: This is a case control study of 142 women with PCOS and 140 age- and BMI- matched controls...

BACKGROUND: d-chiroinositol (DCI) is a inositolphosphoglycan (IPG) involved in several cellular functions that control the glucose metabolism. DCI functions as second messenger in the insulin signaling pathway and it is considered an insulin sensitizer since deficiency in tissue availability of DCI were shown to cause insulin resistance (IR). Polycystic ovary syndrome (PCOS) is a pathological condition that is often accompanied with insulin resistance. DCI can positively affects several aspect of PCOS etiology decreasing the total and free testosterone, lowering blood pressure, improving the glucose metabolism and increasing the ovulation frequency...

Polycystic ovary syndrome (PCOS) is a highly prevalent endocrine metabolic disorder and is presently considered a family pathology. It is associated with obesity, insulin resistance and metabolic syndrome. Racial, ethnic and environmental factors may be important in determining the clinical manifestations of this syndrome. Polycystic ovary syndrome is an exclusion diagnosis and, therefore, should be distinguished from the physiological changes typical for the age and from other hyperandrogenic disorders. Early diagnosis is important since this syndrome is associated with reproductive, oncologic and metabolic risks...

Cardiovascular (CV) disease is the most common cause of morbidity and mortality worldwide, particularly in the presence of the metabolic syndrome (MetS). Classifications and treatment of the MetS have recently been redefined. While the majority of the cardiac components such as hypertension, diabetes mellitus (DM) and dyslipidemia are objectively measurable elements, a few disparities among the definitions have to be considered that can variably modify diagnosis, treatment and prevention. Noncardiac factors such as liver disease (including, but not limited to, alcoholic and non-alcoholic steatosis/hepatitis), renal disease, severe obesity, polycystic ovarian syndrome and obstructive sleep apnea, may have independent or synergistic relationship with complementary cardiac MetS elements, and these additional risk factors may have an incremental adverse impact on CV outcome...

Polycystic ovary syndrome (PCOS) is a complex endocrine disorder affecting 5-10 % of women of reproductive age. It generally manifests with oligo/anovulatory cycles, hirsutism and polycystic ovaries, together with a considerable prevalence of insulin resistance. Although the aetiology of the syndrome is not completely understood yet, PCOS is considered a multifactorial disorder with various genetic, endocrine and environmental abnormalities. Moreover, PCOS patients have a higher risk of metabolic and cardiovascular diseases and their related morbidity, if compared to the general population...

Polycystic ovary syndrome (PCOS) is a prehistoric complex genetic trait, perhaps dating back at least 50,000 years. The disorder also represents an evolutionary paradox, demonstrating clear reproductive disadvantages (i.e., lack of evolutionary fitness), albeit persisting tens of thousands of years. Here we examine possible explanations for this paradox. We evaluate a variety of possible benefits accruing to women in ancestral populations who possessed this trait, including considerations of whether dramatic changes in environment and lifestyle from the ancestral past to the contemporary present have altered the selection dynamics operating on the trait...

Poly Cystic Ovarian Syndrome (PCOS) is one of the most common metabolic and reproductive disorders among women of reproductive age. Women suffering from PCOS present with a constellation of symptoms associated with menstrual dysfunction and androgen excess, which significantly impacts their quality of life. They may be at increased risk of multiple morbidities, including obesity, insulin resistance, type II diabetes mellitus, cardiovascular disease (CVD), infertility, cancer, and psychological disorders. This review summarizes what the literature has so far provided from guidelines to diagnosis of PCOS...

Metabolic diseases dramatically affect life of men and women from infancy up to old age and are a major challenge for clinicians. Health professionals are confronted with different needs of women and men. This article aims at an increase of gender awareness and the implementation of current knowledge of gender medicine in daily clinical practice with regard to pre-diabetes and diabetes. Sex and gender affect screening and diagnosis of metabolic diseases as well as treatment strategies and outcome. Impaired glucose and lipid metabolism, regulation of energy balance and body fat distribution are related to steroid hormones and therefore impose their influence on cardiovascular health in both men and women...

Polycystic ovarian syndrome represents the most common endocrine disease of women of reproductive age. Symptoms include metabolic, gynecologic and cosmetic features. Genetic factors seem to contribute to the disease, affecting not only women but also male relatives of patients with similar symptoms. Besides, lifestyle factors play a central role impacting clinical PCOS appearance. Following we present an overview of the syndrome, its epidemiology, metabolic and gynecological aspects, gender and genetic factors and its therapy...

Follicle stimulating hormone (FSH) plays a central role in growth and differentiation of ovarian follicles. A plethora of information exists on molecular aspects of FSH responses but little is known about the mechanisms involved in its cross-talk with insulin/IGF-1 pathways implicated in the coordination of energy homeostasis in preovulatory granulosa cells (GCs). In this study, we hypothesized that FSH may regulate IRS-2 expression and thereby maintain the energy balance in GCs. We demonstrate here that FSH specifically increases IRS-2 expression in human and rat GCs...

A strong link between obesity, insulin resistance, and metabolic syndrome has been reported with development of a new paradigm to type 2 diabetes mellitus (T2DM), with some evidence suggesting that beta-cell dysfunction is present before the onset of impaired glucose tolerance. Differentiating type 1 diabetes mellitus (T1DM) from T2DM is actually not very easy and there exists a number of overlapping characteristics. The autoantibody frequencies of seven antigens in T1DM patients may turn out to be actually having T2DM patients (pre-T2DM)...

Polycystic ovary syndrome (PCOS) is the most common hormonal disorder among reproductive-age women and is associated with a high risk for metabolic disorders. Adiposity and insulin resistance are two prevalent conditions in PCOS and the likely culprits for the heightened metabolic risk. Up to 60% of women with PCOS are considered to be overweight or obese, and even among non-obese women with PCOS there is an increased accumulation of adipose tissue in abdominal depots. Insulin resistance in PCOS is unique and independent of obesity, as even non-obese women with this condition are frequently insulin resistant...

Polycystic ovary syndrome (PCOS) is a common endocrinopathy affecting reproductive-aged women. PCOS has been recognized as a syndrome combining reproductive and metabolic abnormalities with lifelong health implications. Cardiometabolic alterations require regular screening and effective and targeted lifestyle advice to lose weight as well as to prevent weight gain. Pharmacological therapy includes insulin-sensitizer drugs and agents that act directly on metabolic comorbidities, such as statins and antiobesity drugs...

CONTEXT: Polycystic ovary syndrome (PCOS), a complex and heterogeneous endocrine condition, is characterized by polycystic ovaries, hyperandrogenism, insulin resistance and chronic anovulation. Cumulus granulosa cells surrounding the oocyte are involved in different aspects of PCOS pathology. Several studies suggested that miRNAs play an important regulatory role at the post-transcriptional level in cumulus granulosa cells. OBJECTIVE: Our objective was to describe the altered miRNA expression profiles and miRNA targeted signaling pathways in PCOS...
