119 Clinical Trials for Various Conditions
Polycystic ovary syndrome (PCOS) is a syndrome which includes elevated androgen levels, irregular menstrual cycles and insulin resistance. Standard treatments, which include weight loss and medications to improve insulin secretion are only partly successful, and may require that young women take medications for decades. The study investigators have been evaluating the effects of specific diets on insulin resistance in healthy volunteers and subjects with type 2 diabetes, and have found that subjects with insulin resistance seem to respond particularly well to these diet regimens. Volunteers with PCOS are being asked to participate to see if following these diets can help regularize your menstrual cycles. The results of this study may help improve fertility treatments for women with PCOS.
The investigators aim is to conduct a prospective un-blinded pilot study of premenopausal women diagnosed with Polycystic Ovarian Syndrome (PCOS), defined using criteria developed at the 1990 NICHD conference on PCOS, undergoing treatment for ovulation induction with Metformin. We propose that improving insulin sensitivity with use of Metformin in women diagnosed with PCOS has facilitatory influences on the uterine endometrium.
This multicenter, randomized, open-label exploratory study will be performed in approximately 200 polycystic ovary syndrome (PCOS) but otherwise healthy females undergoing in vitro fertilization (IVF). Each study center will follow its standard practice for in vitro fertilization (IVF) within the study parameters as noted in this protocol. The study centers will use marketed products purchased from Schraft's Pharmacy for all phases of the study (down-regulation, stimulation, ovulation induction, and luteal support). Subjects will be randomly assigned to highly purified menotropin (Menopur®) or follitropin beta (Follistim Pen®) for stimulation and progesterone vaginal insert (Endometrin®) or progesterone in oil for luteal support. Subjects will return to the study center for regular scheduled clinic visits as required per in vitro fertilization (IVF) protocol at the site and at specified times during the cycle (Stimulation Day 6, Day of human chorionic gonadotropin (hCG), and first serum pregnancy test) for estradiol (E2), progesterone (P4) and human chorionic gonadotropin (hCG) labs. All subjects will be required to complete a final study visit at completion of luteal support or negative serum pregnancy test following embryo transfer.
A goal of this study is to use a novel methodology to determine whether insulin resistance in women with polycystic ovary syndrome (PCOS) is related to the accumulation of proteins with modifications. This could lead to future research to determine if these modifications interfere with their proper function. Additionally, the investigators will determine how protein quality is affected by exercise training. Aerobic exercise enhances the endogenous oxidant buffering systems which may minimize oxidative damage to proteins. The investigators propose that aerobic exercise minimizes the accrual of modified proteins by increasing the synthesis of new proteins, but also by increasing the degradation and removal of old and damaged proteins. Based on our previous studies the investigators observed that insulin affects plasma protein synthesis and aerobic exercise improves insulin sensitivity not only in muscle but also in liver. The investigators therefore propose that aerobic exercise and related increase in insulin sensitivity (and decline in insulin levels) will reduce accumulation of old and modified skeletal muscle and plasma proteins leading to improved function.
We hypothesize that the combination of natural cycle IVF or low dose gonadotropin injection combined with In Vitro Maturation (IVM) (Natural IVF/IVM) is a viable option for a selected population of infertility patients who cannot tolerate exogenous gonadotropins or are at risk of ovarian hyperstimulation syndrome.
The purpose of this study is to study the effect of a commonly used antibiotic, doxycycline, on the production of ovarian hormones and menstrual cycles in women with Polycystic Ovarian Syndrome (PCOS).
Women with PCOS suffer from excess male hormone (androgen) production by the ovary. Androgen is made by cells that surround follicles that contain eggs. As the follicles (and eggs) grow and mature, there are more androgen producing cells. Women with PCOS have more follicles than normal women and therefore more androgen producing cells. While androgen production has been associated with the number of follicles, the relationship to the individual size of follicles in PCOS or normal women. This study intends to determine whether the size and number of ovarian follicles are correlated to androgen production in PCOS and normal women.
The purpose of this study is to determine the relationship between lipid-induced inflammation and ovarian androgen secretion in women with polycystic ovary syndrome (PCOS); and to examine the effect of salsalate and polygonum cuspidatum extract (PCE) containing resveratrol on lipid-induced inflammation, ovarian androgen secretion, body composition and ovulation in a subset of normal weight women with PCOS.
The primary purpose of this follow-up study is to determine if cinnamon can restore menstrual cyclicity in Polycystic Ovary Syndrome (PCOS) subjects with oligomenorrhea. As a secondary purpose, the investigators intend to confirm the salutatory effect of cinnamon on insulin resistance in larger group of study subjects. Polycystic ovary syndrome (PCOS) is a very common condition found in women of childbearing age. PCOS patients often have irregular periods, extra hair growth, or difficulty becoming pregnant. The syndrome can also be associated with more serious conditions such as heart disease, diabetes, or cancer of the uterus. Although no one knows the cause of the syndrome, scientific studies showed that having too much insulin can be one of the reasons. In fact, almost every overweight woman with PCOS has been found to have high insulin levels. Recently studies using rats and mice have shown that a commonly used spice, cinnamon, may also reduce the body's insulin level. Another study showed that daily use of cinnamon for forty days lowered the blood sugar level in patients with diabetes. Our own study also showed that using cinnamon everyday for 8 weeks decreased insulin resistance in women with PCOS. The purpose of this study is to see if cinnamon can help women with PCOS have more regular periods.
This pilot study will be a prospective investigation to study the efficacy and safety of In-Vitro Maturation (IVM) for women with Polycystic Ovarian Syndrome (PCOS). There will be 10 subjects total in this Study. There will be no blinding to treatment. In-Vitro Maturation will provide a viable, safe option for women with PCOS attempting pregnancy through the use of Assisted Reproductive Technology (ART).
Women with Polycystic Ovary Syndrome (PCOS) between the age of 18 and 55 are being recruited to participate in an online survey to determine the impact of PCOS on quality of life and interaction with the healthcare system. This online survey will take 15-20 minutes to complete. Participants will receive no direct benefit, but the information provided will contribute to the knowledge of this condition and the development of improved healthcare for women with PCOS.

The purpose of this research study is to explore the relationship between the gut microbiome and hormone levels in women diagnosed with PCOS and determine whether there are differences in the gut microbiome between women with PCOS and women without PCOS. Consented, enrolled participants will complete a health questionnaire, complete a fasted blood draw at a local laboratory, and provide a stool, saliva, and vaginal swab sample for comprehensive biomarkers, hormones, metagenomics, and metabolomics analysis.
The purpose of this study is to see if substances contained in ginger or aloe plants, called exosomes, will treat and improve the condition polycystic ovary syndrome
Open-label randomized clinical trial assessing the efficacy of Metformin versus Vitamin D in improving symptoms of depressed mood in polycystic ovary syndrome.
This project, "A double-blind placebo-controlled randomized clinical trial assessing the efficacy of metformin for hepatic fat in adolescents and young adults with polycystic ovary syndrome", proposes exploring the use of novel and noninvasive methodologies in an at-risk adolescent and young adult population with polycystic ovary syndrome (PCOS) who may gain long-term health benefits from early detection and treatment of non-alcoholic fatty liver disease (NAFLD). PCOS is a common condition that frequently presents in adolescence and young adulthood and is defined by elevated androgens (male hormones) in the blood leading to 1. hirsutism and acne and 2. menstrual abnormalities or amenorrhea. Affected individuals are at increased risk of developing insulin resistance (a precursor of diabetes), NAFLD and lipid (cholesterol) abnormalities.These features are all associated with the metabolic syndrome, a rising major public health concern. Recently, an association between PCOS and NAFLD has been noted but has only been superficially studied in the adolescent and young adult population. The susceptibility of certain PCOS patients to developing NAFLD is theorized to be due to having underlying insulin resistance, elevated androgen levels, and a genetic predisposition. Metformin is an insulin sensitizing medication widely used to treat type 2 diabetes mellitus that may have beneficial effects on insulin resistance-related conditions including PCOS and NAFLD. Although widely used in PCOS, its effect on NAFLD in this group has not been previously studied. The primary aims of this proposal are: 1) To determine whether PCOS with liver fat \>/=4.8% treated with metformin for six months will have a decline in percentage liver fat compared to a placebo group. 2) To measure the association of the PNPLA3 I148M allele with NAFLD in PCOS at baseline (n=40). 2b) To measure the association of percentage liver fat with biomarkers of NAFLD, dyslipidemia, insulin resistance and body composition at baseline (n=40) and after a placebo-controlled intervention with metformin in PCOS with liver fat \>4.8% (n=20). The goal of this research proposal is to explore the use of novel and noninvasive technologies in a young and at risk population. Dr. Sopher hopes to use the results of this research to lay the groundwork for the prevention and treatment of NAFLD and other metabolic disorders in adolescents and young adults with PCOS and to prevent lifelong morbidity associated with PCOS.
The investigator's global hypothesis is that women with Polycystic Ovary Syndrome (PCOS) can be separated into subtypes based on their response to metformin. The investigators propose here to use both targeted and non-targeted metabolomic approach to identify pathways associated with metformin's effect on insulin sensitivity and endothelial function. This pilot project will be the foundation for developing tailored therapeutic approaches to Polycystic Ovary Syndrome and identifying novel drug targets.
The purpose of this research study is to see if there are differences between African-American and Caucasian girls with Polycystic Ovary Syndrome (PCOS) in how their bodies respond to a type of sugar, called glucose, the body's main source of energy. PCOS is one of the most common endocrine disorders among females. Features can include anovulation (eggs are not released from the ovaries) resulting in irregular menstrual periods, excessive amounts of androgenic (male) hormones resulting in acne and hirsutism (excessive hair growth on the face and body), and polycystic ovaries (small sac-like structures \[cysts\] on your ovaries) seen on ultrasound. Girls with PCOS also have higher levels of insulin in their bodies (called hyperinsulinism) but are not able to use insulin very well (called insulin resistance) resulting in an increased risk of diabetes. Diabetes is when you have high levels of glucose (sugar) in your blood. Many studies have looked at how bodies respond to glucose and have shown that compared to Caucasians, healthy African-Americans produce much more insulin (hyperinsulinism) but are not able to use it as well (insulin resistance) in childhood, adolescence, and adulthood. Insulin is a hormone that helps glucose move from the blood into the muscles for the body to use as energy. PCOS is associated with increased levels of insulin (hyperinsulinism) and not being able to use it as well (insulin resistance). So we want to see if there is a difference in insulin production (secretion) and insulin resistance between African-Americans and Caucasians girls with PCOS. To do this, we will look at blood glucose and insulin levels in response to giving glucose in African-American and Caucasian girls who have PCOS. The results of this study may ultimately help to more effectively target treatment therapy in individuals with PCOS that have increased insulin secretion and/or increased insulin resistance.
The purpose of this study is to collect data to help understand why some women develop Polycystic Ovary Syndrome (PCOS) associated with decreased lower-body fat.
The purpose of this study is to determine the effects of stress reduction on glucose, blood pressure, quality of life and overall health and well-being in overweight or obese women, either with Polycystic Ovary Syndrome (PCOS) or without PCOS (non-PCOS). Stress reduction treatment sessions will include one or more of the following activities: breathing exercises, meditation, stretching exercises or health education activities.
The classic description of polycystic ovary syndrome (PCOS) is that it is a disorder characterized by menstrual irregularity, chronic anovulation, androgen excess, and abnormal gonadotropin secretion. Use of combined oral contraceptives (OCs) in women with PCOS effectively reduces circulating androgens. Although OCs are the most common and one of the oldest symptomatic treatment modalities for androgenic skin symptoms and for irregular menstrual cycles caused by hyperandrogenism, the data concerning the effect of treatment of PCOS women with different body mass index (BMI) are limited. This study is being done to compare the hormone and metabolic changes after treatment with low-dose oral birth control regimen of DRSP 3 mg/EE 0.02mg/levomefolate calcium 0.451 mg (Beyaz™) in women with PCOS with different body weights.
In women with polycystic ovary syndrome (PCOS), the cardinal physiological abnormality is excessive ovarian androgen production marked by increased serum testosterone (T) and androstenedione (A) levels. Studies to determine the alteration in ovarian steroidogenesis that lead to abnormal production of ovarian androgens have revealed increased CYP17 gene expression with accentuated 17-hydroxylase activity leading to exaggerated 17-hydroxyprogesterone (17P) responses to luteinizing hormone (LH) stimulation. In contrast, T and A responses did not distinguish between PCOS and normal women, although these androgens were clearly greater in the former compared to the latter group. As a result, 17P responsiveness has been employed to determine the functional capacity of the ovary to produce androgens. The stimulatory agents that have been used included GnRH agonist, Lupron, at a dose of 10 microgram per kilogram, or hCG at a dose of 10,000 IU. The investigators propose to conduct a study that will determine the pattern of androgen responsiveness to 25ucg of hCG after 24 hours in adolescents with PCOS, those with oligomenorrhea, and in normal controls. This will allow for a comparison of these adolescents' ovarian functional capacity to produce androgens.
Polycystic ovary syndrome (PCOS) affects 5-10% of women of reproductive age, and is associated with infertility, risk for obesity and type 2 diabetes, and impaired quality of life. The elevated insulin characteristic of PCOS is likely to play a major role in its symptoms. Manipulation of dietary carbohydrate quantity and quality (glycemic load; GL) may lower insulin and improve both reproductive and metabolic outcomes. The purpose of this study is to determine if a lower GL diet intervention is more effective than a standard (STD) diet in improving reproductive and metabolic outcomes of women with PCOS in the absence of weight loss.
The purpose of this study is to determine if vitamin D will improve insulin resistance, inflammation, and overall well-being in women with PCOS.
Our hypothesis is that hyperinsulinemia increases the renal clearance of D-chiro-inositol (DCI) in women with polycystic ovary syndrome (PCOS) and that this leads to a reduction in circulating insulin-stimulated D-chiro-inositol-containing inositol phosphoglycan (DCI-IPG) release. To assess the effects of a chronic reduction in circulating insulin on DCI metabolism, we propose to reduce circulating insulin in obese women with PCOS by improving insulin sensitivity with the drug pioglitazone. Pioglitazone is a thiazolidinedione that improves peripheral insulin sensitivity, presumably by activation of the peroxisome proliferator-activated receptor gamma (PPARγ) receptor. Administration of pioglitazone to women with PCOS has been shown to improve insulin sensitivity, reduce insulin secretion, and decrease both fasting and post-prandial serum insulin concentrations.
The mechanism for increased androgen production in women with polycystic ovary syndrome (PCOS) is not well understood. Excess androgen production by the ovary is stimulated by increased pituitary luteinizing hormone (LH) secretion in this disorder. The investigators hypothesize that in PCOS women ovarian theca cells, which are responsible for androgen synthesis, are more sensitive to LH stimulation compared to that of theca cells from normal women. To test this hypothesis, the investigators propose to conduct a dose-response study in which androgen responses to multiple doses of human chorionic gonadotgropin (hCG), an LH surrogate, will be assessed in PCOS and normal women.
The goal of this three-armed randomized controlled trial is to establish the relative roles of treatment of hyperandrogenism versus obesity (as the largest modifiable factor contributing to insulin resistance) in treating infertility and improving pregnancy outcomes among obese PCOS women. The investigators hypothesize that the key to restoring ovulation leading to live birth is to correct hyperandrogenism with oral contraceptive pills, but the key to avoiding later pregnancy complications is to improve insulin sensitivity with weight loss.
The purpose of this study is to determine if insulin resistance (how well the body uses insulin and clears sugar) can affect cortisol levels in normal healthy women and women with polycystic ovary syndrome of all body weights.
The purpose of this research study is to determine if adding Metformin, a drug that reduces insulin resistance, to birth control pills will reduce the risk of developing type 2 diabetes, high blood pressure. high lipid levels and heart disease in women with PCOS
The purpose of this study is to determine the efficacy of Lipitor (Atorvastatin) for the treatment of PCOS with elevated LDL cholesterol.
Polycystic ovary syndrome (PCOS) is among the most common endocrine disorders in premenopausal women, affecting 7-10% of this population. This syndrome is characterized by elevated levels of testosterone and chronic anovulation, and frequently of obesity. This study is designed to test the hypothesis that there is in utero testosterone excess, altered insulin secretion, and/or intrauterine growth retardation in the female offspring of women with PCOS. The allele 8 can be used to identify the reproductive and metabolic abnormalities associated with PCOS. This study will determine whether allele 8 positive \[A8(+)\] female offspring have more profound changes in these parameters compared to A8(-) female offspring. Androgen and insulin levels in amniotic fluid from pregnant women with PCOS will be compared to levels in pregnant control women. Androgen and insulin levels in cord blood will also be measured. Further, gestational age and anthropomorphic measurements in offspring of women with PCOS will be assessed and compared to that in offspring of matched control women. We will test the hypothesis that androgens are elevated in infancy in the female offspring of women with PCOS. We will assess sex steroids, insulin, and c-peptide levels in infants of PCOS women and compare them to the levels in infants of control women up to 1 year of age during the minipuberty of infancy. We will determine whether any of these parameters differ in A8(+) compared to A8(-) PCOS offspring.
