PIMS vs PGT-A in Infertile PCOS Patients

This experiment has become a serious issue for two reasons: DNA methylation plays an important role during embryogenesis, global abnormal methylome reprogramming often occurs in human embryos, and DNA methylome pattern is associated with live birth rate. The endocrine metabolic disorders of polycystic ovarian syndrome (PCOS) patients may affect the epigenetic status of embryos and lead to the increase of early pregnancy loss rate in PCOS patients. However, there is still no technology using DNA methylome as an indicator in preimplantation embryo screening in PCOS patients. Our recent study showed that using Pre-implantation Methylation Screening (PIMS) can select embryos with better methylation state and euploid chromosomes. The efficiency of PIMS in PCOS patients needs further validation through randomized controlled clinical trial. The purpose of the study is to compare whether the two groups of PCOS patients who selected embryos using PIMS and selected embryos using "PGT-A + morphology"had any difference in early pregnancy loss rate. This study aims to explore whether PIMS can be used as another embryo evaluation method besides "PGT-A+morphology" to screen good developmental potential embryos in patients with PCOS. Investigators need to clarify whether a better embryo evaluation system can be established through PIMS technology during assisted reproductive treatment for infertile PCOS couples and provide credible and effective evidence-based medical evidence for the application of PMIS technology in the field of reproductive medicine.

Adipokines in Polycystic Ovary Syndrome

The aim of the study is to compare the concentrations of leptin, resistin, and omentin-1 in women across three research groups: those with polycystic ovary syndrome without insulin resistance, those with polycystic ovary syndrome with insulin resistance, and women without polycystic ovary syndrome.

Does combined Cabergoline and letrozole increase ovulation rate What medical problems do participants have when taking drug Cabergoline and Letrozole ? Researchers will compare drug combination of Cabergoline and letrozole to letrozole alone to see combined cabergoline and letrozole works better as ovulation induction. Participants will: experimental group will receive Cabergoline and Letrozole comparator group will receive letrozole alone TVS Monitoring will be done for 3 cycle for ovarian response

Fish Oil, Metformin and Heart Health in PCOS

Women with Polycystic Ovary Syndrome (PCOS) have high testosterone levels which is associated with altered insulin-glucose metabolism and an adverse blood lipid profile, predisposing them to the development of Type II Diabetes and Cardiovascular Disease (CVD). This study will investigate the use of dietary fish oil supplementation as a safe and effective intervention, and as an adjunct therapy to standard of care treatment with metformin to improve heart health, blood lipids and insulin-glucose metabolism in women with PCOS, and those with PCOS and Type 2 Diabetes.

Cardiovascular and Endothelial Markers During OGTT Before and at Six and Twelve Months Post-treatment in Women With PCOS

The aim of the present study is to investigate a) the presence of subclinical markers of vascular, myocardial and endothelial function in women with PCOS b) the acute alterations in these markers during the oral glucose tolerance test (OGTT) c) the impact of potential treatment interventions in these markers.

Liraglutide Treatment in Obese Infertile PCOS Women

Liraglutide, a hypoglycemic drug, can reduce weight and improve insulin resistance while stabilizing blood glucose metabolism without increasing the risk of hypoglycemia, and has been approved by the State Food and Drug Administration of China and the US Food and Drug Administration for the treatment of obesity. Polycystic ovary syndrome (PCOS) is the main cause of female anovulatory infertility, and it is also a high-risk group of obesity. Previous studies have suggested that liraglutide improves glucose metabolism, body weight, and inflammation levels in obese women with PCOS, and improves sex hormone profiles and menstrual cycles, possibly contributing to increased fertility. Therefore, this project intends to test the following hypothesis through a large sample randomized controlled trial in obese and infertile PCOS women who are assisted by in vitro fertilization-frozen embryo transfer (IVF-FET), using liraglutide before transplantation to reduce weight can improve the live birth rate of assisted reproduction.

Bicalutamide Therapy in Young Women With NAFLD and PCOS

Nonalcoholic steatohepatitis (NASH), or fat-related liver inflammation and scarring is projected to be the leading cause of cirrhosis in the United States (U.S.) within the next few years. Women are at disproportionate risk for NASH, with approximately 15 million U.S. women affected. There is an urgent need to understand risk factors for NASH and its progression in women, and sex hormones may provide a missing link. This study will study the contribution of androgens to liver injury and progression in PCOS and mechanistic role of dysregulated lipid metabolism and visceral adiposity in this process. Such findings will provide the rationale for future efficacy studies evaluating selective androgen receptor (AR) antagonism for NASH in PCOS, or alternatively, the need to directly target visceral adiposity or lipid-specific pathways as part of a precision medicine approach to halt fibrosis progression in the nearly 5 million young women with PCOS and NAFLD in the U.S., who remain at increased risk for early onset and progressive liver disease.

Randomized Controlled Trial of Combined Letrozole and Clomid (CLC II) Versus Letrozole Alone for Women With Anovulation

This study evaluates the addition of clomiphene citrate (CC) to letrozole for the treatment of infertility in women with polycystic ovary syndrome across a course of two treatment cycles with stair step dosing of letrozole similar to standard of care. Half of the participants will receive letrozole and CC in combination, while the other half will receive letrozole alone.

Safety of Cultured Allogeneic Adult Umbilical Cord Derived Mesenchymal Stem Cells for PCOS

This trial will study the safety and efficacy of cultured allogeneic adult umbilical cord derived mesenchymal stem cells delivered intravenously for the treatment of Polycystic Ovary Syndrome.

Androgens and NAFLD Longitudinal Cohort Study

The researchers want to learn how androgens, a type of sex hormone, might affect nonalcoholic fatty liver (NAFLD) in young women over time. NAFLD happens when fat builds up in the liver which can cause damage to the liver such as inflammation or scarring. Young women with a condition called polycystic ovary syndrome (PCOS) have a high risk for NAFLD, and they often have high androgen levels too. So the researchers are recruiting young women with PCOS as well as those without PCOS, and will compare changes in NAFLD over time between young women with and without PCOS. This study is funded by the National Institutes of Health

Transcriptional and Epigenetic Program of PCOS Women

The main goal is to reveal differences in global gene expression in two different adipose tissue (AT) depots of females with and without polycystic ovary syndrome (PCOS) and how these are influenced by upstream epigenetic markers

Exogenous Ketone Supplementation in Females with Polycystic Ovary Syndrome

Polycystic ovary syndrome (PCOS) affects 1 in 5 females of reproductive age. Commonly characterized as a disorder of infertility, PCOS is often accompanied by 3 potent cardiovascular disease (CVD) risk factors: insulin resistance, endothelial dysfunction, and elevated blood pressure. Accordingly, PCOS is associated with the development of CVD, the second leading cause of death in females in Canada. However, effective treatments to improve cardiovascular health in PCOS are lacking. Exogenous ketone monoester (KME) ingestion has been shown to improves outcomes associated with insulin resistance, endothelial function, and blood pressure regulation in healthy individuals and individuals predisposed to CVD. Therefore, oral ketone supplements offer a practical and effective strategy for improving cardiovascular health; however, this treatment has yet to be evaluated in PCOS. Therefore, the overall goal of this project is to employ KME ingestion to improve markers of cardiovascular health in females with PCOS. On two different days, participants will consume either a beverage containing a ketone supplement or a beverage containing a placebo supplement. The objectives are to compare responses between KME and placebo ingestion, and examine all outcomes related to cardiovascular health in females with PCOS in comparison with female controls of similar age and body mass index. The effects of KME ingestion will be quantified on: 1) glycemic control during an oral glucose tolerance test; 2) endothelial function using the flow-mediated dilation test; 3) blood pressure and acute blood pressure regulation; and 4) hemodynamic responses to acute exercise.

In Vitro Maturation of Human Eggs

CCRM Fertility, a global pioneer in fertility treatment, research and science, is seeking participants for a new study on in vitro maturation (IVM). IVM requires less hormones to stimulate the ovaries than IVF, making it more affordable than IVF with fewer side effects. Participants that qualify for the study will receive a free cycle of IVM treatment at CCRM Fertility and including a new patient consultation, fertility testing, preimplantation genetic testing for aneuploidies (PGT-A), anesthesia and some medication

Lifestyle Changes in PCOS with OSA and NAFLD

Complain of obstructive sleeping apnea and fatty liver is common in PCOS women so lifestyle changes are recommended

Effects of Sprint Interval Training Versus Arabic Exercises BMI

Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in women of reproductive age and is the leading cause of infertility and anovulation. According to the Rotterdam criteria, the prevalence of PCOS is estimated to affect up to 20% of the female population. PCOS is characterized by increased androgen production and decreased ovulation leading to clinical manifestations including acne, hirsutism, male pattern baldness, irregular menstrual cycles, and infertility. In addition to concerns about fertility and hyperandrogenism, PCOS is considered a metabolic disorder, with an increased risk of developing insulin resistance (IR), hyperinsulinemia, dyslipidemia, and low-grade inflammation. In addition to genetic involvement, environmental aspects such as obesity conditions. affect the progression of PCOS or even make patients' clinical conditions worse. Exercise is an important component of PCOS management, and exercises have been shown to improve metabolic and reproductive outcomes in women with PCOS. The study will be a randomized clinical trial. This study will be completed in a time duration of 7 months after the approval of the synopsis. Sample size 32 is calculated by the Epi tool.variable for the sample size is BMI. By the non-probability convenience sampling technique, participants will be divided into 2 groups. Group A the Interventional group will receive SIT and Group B will receive the aerobic exercise. Group A will perform SIT 3 times a week for 30-second sprints on a cycle ergometer with 4 minutes of rest between each sprint, complete session will be for 30 -40 minutes while Group B will perform the aerobic exercise for 30-40 minutes of moderate-intensity continuous exercise on a treadmill and stationary cycle. The outcome measure will be evaluated by using the BMI Calculator, PCOSQOL, measuring tape Borg scale. After Collecting data from the before and after treatment sessions. The data will be analyzed by using SPSS version 25.
