Polycystic ovary syndrome (PCOS) is a common condition characterised by both reproductive and metabolic features (obesity, insulin resistance, diabetes risk). Some evidence suggests that women with PCOS have lower vitamin D levels compared to healthy controls. Vitamin D binding protein (DBP) is the main carrier of vitamin D in circulation and plays an important role in regulating vitamin D concentration and bioavailability for target tissues. To our knowledge, no previous studies have examined DBP, bioavailable and free 25-hydroxyvitamin D (25(OH)D) in women with PCOS...

Carbon monoxide poisoning (COP) causes hypoxic injury and inflammatory and immunological reactions in the brain and local organs including the pancreas. Therefore, it is plausible that COP may increase the risk for developing diabetes mellitus (DM), but studies on this possible association are limited. We conducted a nationwide study in Taiwan to fill the data gap. We used the Nationwide Poisoning Database and the Longitudinal Health Insurance Database 2000 to identify all COP patients diagnosed between 1999 and 2012 (the study cohort) and then construct a comparison cohort of patients without COP through matching at 1:3 by the index date and age...

The Androgen Excess and Polycystic Ovary Syndrome Society (AEPCOS) has recommended an updated threshold for polycystic ovarian morphology (PCOM) of 25 follicles or more, 10 ml or more of ovarian volume, or both. We describe the effect of these guidelines on reproductive and metabolic characteristics in 404 women. These women were separated into four groups: group A: hyperandrogenism and oligo-amenorrhoea (n = 157); group B: hyperandrogenism or oligo-amenorrhoea and PCOM meeting AEPCOS 2014 criteria (n = 125); group C: hyperandrogenism or oligo-amenorrhoea and PCOM meeting Rotterdam 2003 but not AEPCOS 2014 criteria (n = 72); and group D: non-PCOS not meeting either criteria (n = 50)...

The prevalence of PCOS was investigated in many studies in different continents. However, there is no established prevalence of PCOS for distinct ethnic groups. In the current analysis, we conducted searches in PubMed, The Cochrane Library, EMBASE, CINAHL up to Jan. 2017 to identify studies reporting prevalence of PCOS in the general female population. Forty-two studies were identified, with 13 eligible for evidence synthesis. The prevalence among different ethnicity was estimated using random effect modelling...

OBJECTIVE: Polycystic ovary syndrome (PCOS) is commonly affected by obesity. PCOS phenotypes are prone to increased waist/hip ratio, insulin resistance and dyslipidaemia. This substudy was undertaken to evaluate the effects of lifestyle interventions on metabolic biomarkers in overweight/obese PCOS women, and the interventional effects of dietary components related to metabolic outcomes. DESIGN: Randomized three-arm parallel study. PATIENTS: Fifty-seven PCOS women (BMI >27kg/m(2) , age 18-40) were randomly assigned to diet (D, n=19), exercise (E, n=19) or diet plus exercise (DE, n=19) in three-arm fashion over 16 weeks...

OBJECTIVES: There is some evidence that the efficacy of metformin as an ovulation stimulation agent depends on the body mass index (BMI) of the treated anovulatory women with polycystic ovary syndrome (PCOS). The aim of this study was to examine the likelihood of successful ovulation among obese (BMI ⩾30 kg/m(2)) versus non-obese (BMI <30 kg/m(2)) women with PCOS. METHODS: A total of 243 medical charts of women with PCOS who visited King Khaled University Hospital (KKUH) in Riyadh, Saudi Arabia, between 2006 and 2012 were reviewed...

OBJECTIVE: Polycystic ovary syndrome (PCOS) is the most common endocrinopathy of women of reproductive age and a complex endocrine condition, due to its heterogeneity and uncertainty about its etiology. However, PCOS is also associated with other metabolic abnormalities such as insulin resistance, impaired glucose tolerance, and diabetes. There are few medications that are approved for the most common symptoms of PCOS, leading to the off-label use of medications that were approved for other indications...

Polycystic ovary syndrome (PCOS) is a common complex and heterogeneous disorder, affecting up to 10% women at reproductive age. It causes three fourth of the ovulatory infertility and PCOS patients often give poor IVF quality. Although some metabolic profiles have been investigated in PCOS patient sera and urine, the follicular fluid, providing fruitful biochemical information about oocyte environment during development has been ignored. In this work, based on NMR metabolomics approach, metabolic profile of follicular fluid of PCOS patients has been explored and compared with healthy controls...

Aleksandra Kruszyńska, Jadwiga Słowińska-Srzednicka
Anti-Müllerian hormone (AMH) in women is secreted by granulosa cells in late preantral and small antral follicles. AMH seems to be a very stable marker having some advantages over other biochemical and biophysical markers and is very useful in the assessment of ovarian reserve. AMH measurement may be used in cases of premature ovarian failure, including iatrogenic, due to treatment for cancer, hypogonadotropic hypogonadism, and lastly, in polycystic ovary syndrome (PCOS). It is also a very specific marker of ovarian tumors - folliculomas...

Study 1 Development of the questionnaire Most questionnaires on attitudes toward motherhood presume that the subject is fertile and positive and negative attitudes are represented on a one-dimensional scale. Moreover, the questionnaires often do not provide German versions and German norms. The aim of this study is to examine whether the German Questionnaire on Attitudes toward Motherhood ("FEMu") can be used to describe attitudes toward motherhood multi-dimensionally and whether it is applicable independent of a person's fertility status...

PURPOSE: Polycystic ovary syndrome (PCOS) is an increasingly prevalent disorder in adolescent girls, commonly presenting with hirsutism/oligomenorrhea, commonly treated with an oral contraceptive (OC), and commonly followed by oligoanovulatory subfertility. We tested whether an intervention targeting the reduction of hepato-visceral adiposity is followed by a higher ovulation rate than OC treatment. METHODS: This randomized, open-label, single-center, pilot proof-of-concept study (12 months on treatment, then 12 months off) was performed in adolescent girls with hirsutism and oligomenorrhea (PCOS by National Institutes of Health; no sexual activity; N = 36; mean age 16 years, body mass index 23...

Polycystic ovary syndrome (PCOS) is recognized as one of the most common endocrinopathies in women of reproductive age, associated with metabolic sequelae which includes increased risk factors for impaired glucose tolerance (IGT), type 2 diabetes mellitus (DM2) and cardiovascular disease (CVD). The adverse effects of DM2 affects a woman throughout her lifespan. Health care expenditure of DM2 highlights the need for prevention through appropriate screening, diagnosis and intervention. Lifestyle modification (LSM) programs that include diet and/or physical activity are suggested for patients characterized as prediabetic to delay the onset of adult DM2...

Mechanistic insight into estrogen deficiency by polycystic ovary syndrome (PCOS) remains a longstanding challenge in reproductive medicine. Recent advance suggest that Wingless-type MMTV integration site family members (WNTs), in concert with its Frizzled (FZD) receptors, regulate normal folliculogenesis, luteogenesis and ovarian steroidogenesis. However, no studies have so far investigated any causality between WNT-FZDs interactions and disrupted estrogen synthesis under certain pathological conditions. Here, we show that (i) FZD3 expression was significantly up-regulated in the cumulus cells (CCs) from PCOS patients...

Polycystic ovary syndrome (PCOS) is a common problem among Arab women and is the main cause of infertility due to anovulation. This study investigates insulin resistance (IR) and obesity in different PCOS phenotypes among infertile women (n = 213), of whom 159 had PCOS and 54 women without PCOS, recruited as a control group. Biometric, hormonal and clinical parameters were studied. IR was observed in 133 (83.6%) women with PCOS and in 25 (46.3%) women without PCOS (p < 0.001). IR was significantly associated with PCOS only among women with central obesity (χ(2) = 35...

OBJECTIVE: Prenatal androgen exposure has been suggested to play a role in polycystic ovary syndrome. Given the limited information on what maternal characteristics influence maternal testosterone levels, and the even less explored routes by which female fetus androgen exposure would occur, the aim of this study was to investigate the impact of maternal age, BMI, weight gain, depressed mood, and aromatase SNPs on testosterone levels in maternal serum and amniotic fluid of female fetuses...
