Filter by:The purpose of this study is to determine if changes in blood vessel health lead to the menstrual irregularities that women with PCOS experience. This research study will help determine if women with PCOS have early changes in their blood vessels called "endothelial dysfunction," and if the number of progenitor cells (cells that in a healthy person repair blood vessel damage) are related to these blood vessel changes. To do so, we will compare ultrasound (soundwave) pictures of a large blood vessel in the arm and the results of blood tests between women with PCOS and other healthy women with normal menstrual periods.
This study examines Raloxifene versus Clomiphene to induce ovulation in women with polycystic ovarian syndrome (PCOS).
Polycystic ovary syndrome (PCOS) is often associated with pathological conditions, such as insulin resistance (IR), type 2 diabetes (DM2), obesity and it has potentially increased risk for cardiovascular disease (CVD). Of note, risk factors for CVD including dyslipidaemia, hypertension, oxidative stress and inflammation are associated with PCOS. The investigators want to evaluate the effects of two different types of E/P therapy on cardiovascular risk in PCOS.
The purpose of this study is to explore the genetic basis of reproductive disorders and cleft lip and/or palate.
Both oxidative stress and Bisphenol A (BPA) had been associated with polycystic ovary syndrome (PCOS). BPA, one of endocrine-disrupting chemicals (EDCs), is an environmental estrogen used in the synthesis of plastics, is a "high-volume production" chemical with widespread human exposure. BPA was been reported in several female reproductive disturbance. However, the pathological pathway of BPA impact on female reproductive system had not been well-understood. Reactive oxygen species (ROS) have a role in the modulation of gamete quality and gamete interaction. Persistent and elevated generation of ROS leads to a disturbance of redox potential that in turn causes oxidative stress (OS). The first part of The investigators study is aim to evaluate the oxidative stress impact on the biochemical parameters in women with PCOS; the secondary part of the investigators study is to investigate the BPA on the clinical and biochemical of women with PCOS; finally, the investigators plan to test the hypothesis that BPA might increase oxidative stress and then elevated ROS in women with menstrual disturbance, furthermore, the role of oxidative stress and BPA impact on insulin resistance and metabolic disturbance will be also investigated. Study and control cases will be included. Serum total oxidant status (TOS), total antioxidant status (TAS), Bisphenol A (BPA), and clinical/biochemical parameters will be obtained for all cases. Oxidative stress and BPA will be evaluated with all clinical/biochemical parameters for all subjects.
The purpose of this study is to study the association of serum ferritin and homocysteine levels with insulin resistance and metabolic syndrome in women with polycystic ovary syndrome The polycystic ovary syndrome (PCOS) is a common endocrine disease, affecting 5-10% of women with reproductive age. Insulin resistance and metabolic disturbance are well-known long-term consequence of women with PCOS. Recent evidence suggests that increased body iron might be involved in the pathogenesis of insulin-resistance disorders, furthermore, hyperhomocysteinemia is associated with an increased risk of atherosclerotic and thromboembolic disorder. The investigators plan to retrospectively review the medical records of female patients who visited the Reproductive Endocrinology Clinic at the Wan Fang Medical Center at Taipei Medical University from Jan 1, 2008, to November 30, 2011.
The study provide a detailed longitudinal evaluation of the gluco-insulinemic assessment of pregnant PCOS women under metformin treatment. 47 non diabetic Polycystic Ovary Syndrome (PCOS) women became pregnant during metformin treatment and continued taking the drug during gestation. An oral glucose tolerance test and euglycaemic hyperinsulinaemic clamp were performed at each trimester of gestation.
The main aims of this study are: - to investigate and compare the effects of long lasting use (59 weeks) of vaginal and oral contraceptives on androgen secretion, insulin and glucose metabolism, lipid profile, and serum levels of SHBG and hs-CRP in women with PCOS. - to compare the metabolic effects of oral and vaginal combined contraceptives and to find out whether oral or transvaginal contraceptive can be recommended to a particular group of women, for example in women with increased metabolic risks. - to clarify whether the unfavourable effects of combined contraceptives diminish with time (after use of one year).
The overall aim of the PregMet 2 Study is to investigate whether metformin prevents late miscarriages and preterm deliveries in PCOS women treated with metformin from first trimester of pregnancy to delivery in a large, randomized, controlled, multi-centre trial setting. The investigators hypothesis is that metformin compared to placebo treatment from the first trimester to term, reduces the prevalence of late miscarriage (gestational week 13-22) and preterm birth (gestational week < 37) in PCOS women diagnosed according to Rotterdam 2003 consensus criteria, with singleton pregnancy.
To evaluate long-term effects of drospirenone (DRSP)/ethinylestradiol (EE) alone, metformin alone and DRSP/EE plus metformin on some cardiovascular risk factors in hyperinsulinemic PCOS patients
