BACKGROUND: Polycystic ovary syndrome (PCOS) is a common endocrine and metabolic disorder that affects female fertility. However, with the lack of a corresponding research model, the pathology mechanism of PCOS is poorly understood. Induced pluripotent stem cell (iPSC) technology has been recognized as means to generate patient-specific stem cells for disease modeling. METHODS: The mRNA abundance of iPSCs was analyzed by RNA microarray and real-time polymerase chain reaction (RT-PCR)...

Polycystic ovary syndrome (PCOS) usually arises during puberty and is marked by insulin resistance, hyperinsulinemia, and hyperandrogenism. The principle is that the diagnosis of PCOS must be based on the presence of at least two of the following three criteria: chronic anovulation, hyperandrogenism (clinical or biological), and polycystic ovaries. The diagnosis of PCOS in adolescents is particularly difficult due to developmental problems in this group. Many symptoms of PCOS, including acne, menstrual irregularities, and hyperinsulinemia, are common in normal puberty...

BACKGROUND: Women with polycystic ovary syndrome (PCOS) are almost three times more likely to be obese than those without PCOS. However, we have no specific interventions to induce weight loss so far and rely on drugs used to treat other symptoms of the syndrome or obesity in the general population. OBJECTIVE: The objective of this study is to compare the effectiveness of metformin, inositol, liraglutide and orlistat to induce weight loss in women with PCOS and overweight/obesity...

OBJECTIVES: To investigate the effect of metformin on endometrial receptivity in women with polycystic ovary syndrome (PCOS). METHODS: Twenty volunteer women with polycystic ovaries and oligomenorrhea were prospectively investigated. All women were treated with exogenous estradiol and progesterone to simulate a normal menstrual cycle (28-day duration) after GnRH-induced pituitary desensitization. Ten of the women received no other medication (group A, control), while the remaining 10 received metformin (group B, metformin)...

The aim of the current work was to investigate the value of the long term effects of combined use of simvastatin and metformin treatment for a year versus the effects of their individual treatment on the clinical, biochemical abnormalities, and ovulation dysfunction in young single women with polycystic ovary syndrome (PCOS). It was a randomized, double-blind controlled study. Where two hundreds (n = 200) single young women with PCOS were randomized into seventy (n = 70) women using simvastatin 20 mg daily combined with metformin 500 mg three times daily considered as group A (study group), and another 2 sixty five (n = 65) women groups using simvastatin and metformin individually as a single treatment use, and considered as groups (B & C), respectively...

BACKGROUND: There has been considerable interest in providing antenatal dietary and lifestyle advice for women with obesity or who are overweight during pregnancy, as a strategy to limit gestational weight gain and improve maternal and infant health. However, such antenatal interventions appear to have a modest effect on gestational weight gain and other clinical pregnancy and birth outcomes and additional strategies are required.Metformin is an oral insulin-sensitising medication that acts to decrease blood glucose concentrations...

The aim of this study was to evaluate the risk of major birth defects and spontaneous abortion after metformin use during the first trimester of pregnancy. We conducted an observational cohort study comparing pregnancies with metformin treatment during the first trimester with non-exposed women matched for BMI and year of enrolment. Pregnancies were prospectively ascertained in the German Embryotox pharmacovigilance database between 2004 and 2014. The study sample included 336 pregnancies with metformin exposure for PCOS and fertility disorders (56...

Metformin use in pregnancy is increasing worldwide as randomised controlled trial (RCT) evidence is emerging demonstrating its safety and efficacy. The Metformin in Gestational Diabetes (MiG) RCT changed practice in many countries demonstrating that metformin had similar pregnancy outcomes to insulin therapy with less maternal weight gain and a high degree of patient acceptability. A multicentre RCT is currently assessing the addition of metformin to insulin in pregnant women with type 2 diabetes. RCT evidence is also available for the use of metformin in pregnancy for women with Polycystic Ovarian Syndrome and for nondiabetic women with obesity...

Use of oral agents to treat gestational diabetes mellitus (GDM) remains controversial. Recent recommendations from the Society for Maternal Fetal Medicine (SMFM) assert that metformin may be a safe first line alternative to insulin for GDM treatment and preferable to glyburide. However, several issues should give pause to the widespread adoption of metformin use during pregnancy. Fetal concentrations of metformin are equal to maternal, and metformin can inhibit growth, suppress mitochondrial respiration, have epigenetic modifications on gene expression, mimic fetal nutrient restriction, and alter postnatal gluconeogenic responses...

BACKGROUND: PCOS is a reproductive hormonal abnormality and a metabolic disorder. It is frequently associated with insulin resistance, hyperandrogenism, chronic inflammation, and oxidative stress. We aim to investigate the potential therapeutic effects of combined therapy of resveratrol and metformin on polycystic ovaries via SIRT1 and AMPK activation. METHODS: Wistar albino rats were divided into control and experimental (PCOS) groups. DHEA-induced PCOS rats were given resveratrol (20 mg/kg/day), metformin (300 mg/kg/day) and combined therapy...

Background: Polycystic ovary syndrome (PCOS) is a common form of the endocrine disease which is associated with metabolic dysfunction. PCOS and type 2 diabetes mellitus are related in multiple aspects and are similar in many pathological features. Anti-diabetic effects of Nigella sativa and protective effects of it on reproductive system have been suggested in some reports.

The objective of this narrative review was to suggest a rational order of treatment choices in anovulatory women with polycystic ovary syndrome (PCOS), for whom a multitude of treatment options exist. In obese/overweight women with PCOS the importance of weight reduction should be stressed. Inositol, a dietary supplement with a documented effect on ovulation and without adverse effects in the doses recommended, may be suggested. Additional first-line medical alternatives include insulin sensitizers, selective estrogen receptor modulators, and aromatase inhibitors...

Gallstone disease (GD) is highly correlated with metabolic syndrome and its related illnesses including type II diabetes (DMII) and polycystic ovary syndrome (PCOS). While previous studies claimed that metformin decreases the chance of developing GD in PCOS patients, this phenomenon has not been investigated in animal models to date. Here we fed a high fat diet (HFD) containing 2% of cholesterol and 1% of cholic acid to ten-week-old male C57Bl/6 mice for 105 days. The groups were as follows: Low fat diet; HFD; HFD + Ursodeoxycholic acid (UDCA) (day 1-105); HFD + Metformin (day 1-105); HFD + Metformin (Met) (day 64-105)...

OBJECTIVE: Glucagon-like peptide-1 (GLP-1) has been investigated in regulation of reproductive system in animal models. The potential impact of short-term preconception intervention with liraglutide on fertility potential in polycystic ovary syndrome (PCOS) has not been evaluated yet. DESIGN: A prospective randomized open-label study was conducted in 28 infertile obese PCOS patients (age: 31.07 ± 4.75, BMI: 36.7 ± 3.5 kg/m2 , mean ± s.d.).

Polycystic ovary syndrome (PCOS) is an endocrine disorder, afflicting females of reproductive age. This syndrome leads to infertility, insulin resistance, obesity, and cardiovascular problems, including a litany of other health issues. PCOS is a polygenic, polyfactorial, systemic, inflammatory, dysregulated steroid state, autoimmune disease, manifesting largely due to lifestyle errors. The advent of biochemical tests and ultrasound scanning has enabled the detection of PCOS in the affected females. Subsequently, a huge amount of insight on PCOS has been garnered in recent times...
