The objective of the study is to provide preliminary evidence for the safety and effectiveness of the AblaCare System in transvaginal ablation of ovarian tissue under ultrasound visualization in women with infertility due to polycystic ovary syndrome (PCOS) who have not responded to first-line ovulation induction treatment or are contraindicated for or decline such treatment.
Polycystic Ovary Syndrome, Infertility, Female
The investigators would like to determine how aspects of adiposity and age influence ultrasound features of the ovaries which are used to diagnose polycystic ovarian syndrome (PCOS). The study will also compare anti-Müllerian hormone (AMH) levels against ultrasound features of the ovary to predict PCOS.
Polycystic Ovary Syndrome (PCOS), Menstrual Irregularity, Overweight and Obesity
Polycystic Ovary Syndrome (PCOS) is characterized by hyperandrogenism, ovulatory dysfunction and polycystic ovaries. Insulin resistance (IR) is a common feature of PCOS, and the resultant hyperinsulinemia is theorized to promote hyperandrogenism in the disorder. However, 30-50% of women with PCOS who are lean do not have insulin resistance. Women with PCOS also exhibit chronic low-grade inflammation. In PCOS, glucose ingestion activates nuclear factor ĸB (NFĸB), the cardinal signal of inflammation culminating in upregulation of the inflammation pathway within mononuclear cells (MNC). This phenomenon is independent of excess adiposity and is highly correlated with circulating androgens. In addition, in vitro exposure to proinflammatory stimuli is capable of directly stimulating ovarian theca cell androgen production. Nonacetylated salicylates suppress NFĸB activation and are well tolerated in humans. The proposed research is a randomized double-blind placebo-controlled study of 90 women with PCOS. Forty-five subjects with PCOS (15 lean without IR), 15 lean with IR and 15 obese) receiving salsalate, a nonacetylated salicylate, at an oral dose of 3-4 gm daily for 12 weeks will be compared with 45 age- and body-composition-matched control women with PCOS receiving placebo. The overarching hypothesis is that inflammation contributes to ovarian dysfunction, independent of excess adiposity or IR. The specific aims are, I: To examine the effect of salsalate administration on the ovarian capacity to secrete androgen and on insulin sensitivity in PCOS. II: To examine the effect of salsalate administration on the inflammatory response of mononuclear cells induced by lipid ingestion and glucose infusion in PCOS. The approach involves evaluation of ovarian androgen secretion in response to human chorionic gonadotropin (HCG) administration and insulin sensitivity during the euglycemic phase of a two-step pancreatic clamp along with ovulation monitoring before and after salsalate administration. The inflammatory response of MNC to lipid ingestion and the hyperglycemic phase of the two-step clamp will also be evaluated during treatment by measuring reactive oxygen species, the mRNA and protein content of inflammation markers, NFĸB activation and cytokine release in culture. The investigators expect that women with PCOS receiving salsalate will exhibit decreased ovarian androgen secretion and reduced inflammation regardless of adiposity or IR status. These results will be significant if they show a causal contribution of inflammation to ovarian dysfunction in PCOS, thus improving our understanding of the pathogenesis of PCOS, opening previously unexplored therapeutic avenues that are not necessarily dependent on improving IR, and guiding the design of future studies aimed at determining what interventions will optimally attenuate inflammation in PCOS to reduce medical disease and enhance fertility.

The purpose of this study is to determine if treatment of obstructive sleep apnea (OSA) with continuous positive airway pressure in women with both OSA and polycystic ovarian syndrome will improve the regularity of the women's menstrual cycles.
Sleep Apnea, Obstructive, Anovulation, Polycystic Ovarian Syndrome
The investigators have documented a genetic predisposition for some astronauts to develop ophthalmologic issues (e.g., choroidal folds, cotton wool spots, optic disc edema). Women with polycystic ovary syndrome (PCOS) have several characteristics similar to those described in astronauts, including: higher homocysteine concentrations, increased incidence of intracranial hypertension, increased retinal nerve fiber layer thickness, increased incidence of white matter hyperintensities on MRI, increased androgen concentrations (or androgen responses to space flight), and indices of altered carbohydrate metabolism. Women with PCOS have not been evaluated in detail regarding the occurrence of other anomalies observed in astronauts including choroidal folds, optic disc edema and cotton wool spots as well as changes in cycloplegic refraction, and optic nerve sheath diameter. While researchers have evaluated one-carbon metabolism pathway polymorphisms re: PCOS, and initial studies show an association with certain one-carbon polymorphisms, none have looked at the complete set of SNPs proposed here. This study will evaluate women with PCOS and/or idiopathic intracranial hypertension (IIH) to assess one-carbon biochemistry and genetics and their possible correlation with ophthalmologic findings. The investigators aim to clarify the relationship of one carbon metabolism and ophthalmic findings in astronauts and patients with PCOS and/or IIH.
Polycystic Ovarian Syndrome, Idiopathic Intracranial Hypertension
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.
Polycystic Ovarian Syndrome
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.
Polycystic Ovary Syndrome
Adults with abdominal obesity are at high risk for cardiovascular disease and also exhibit diminished growth hormone (GH) secretion; the latter further contributes to the development of visceral adiposity, impaired fibrinolysis and inflammation.Growth hormone releasing hormone (GHRH), the primary stimulus for endogenous GH secretion, is a substrate of dipeptidyl peptidase 4 (DPP4); inhibition of DPP4 with the currently available anti-diabetic therapy, sitagliptin, may therefore increase GH secretion by decreasing the degradation of GHRH. The proposed research will test the hypothesis that chronic sitagliptin therapy will enhance GH secretion and vascular function while improving glucose tolerance in patients with impaired GH secretion who are at risk for the development of diabetes mellitus and cardiovascular disease, specifically obese women with polycystic ovary syndrome.
Polycystic Ovary Syndrome
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.

The investigators would like to determine how aspects of metabolism and age influence ovarian function. The purpose of the study is to understand how nutrition and metabolism relate to follicle development in women with regular cycles, irregular cycles, or polycystic ovary syndrome (PCOS). We also plan to identify lifestyle factors associated with PCOS and understand how diet and activity levels impact features of PCOS.

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.
Polycystic Ovary Syndrome
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.

Polycystic Ovary Syndrome
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.

The investigators conducted a prospective un-blinded pilot study of Vitamin D plus Calcium (Ca) supplementation in overweight (BMI \> 27) premenopausal women diagnosed with Polycystic Ovarian Syndrome (PCOS), as defined by the Rotterdam Criteria, 2003, and who were deficient in vitamin D as reflected by serum 25-hydroxy (25-OH) vitamin D (serum levels \< 20 ng/mL).
Polycystic Ovarian Syndrome, Vitamin D Deficiency
The overall aim of this study is to explore the effects of flaxseed supplementation and determine whether it is a feasible and potentially effective dietary intervention among women with polycystic ovarian syndrome (PCOS). Women, ages 18-45, with clinically confirmed PCOS (N=20) will be scheduled for baseline measures and then instructed and given supplies necessary to follow a flaxseed supplemented (30 g/day) diet for a period of three months, whereupon follow-up measures will be taken. Subjects will be asked to resume their typical (unsupplemented) diet for another three months and a second set of follow-up measures will be taken. Baseline levels of bioavailable and total testosterone, fasting insulin, glucose, and triglycerides (TG), total/LDL/HDL cholesterol, body weight, degree of hirsutism and acne, and menstrual cyclicity will be compared to levels at 3 and 6 month follow-up. The overall hypothesis (based upon our work in men at risk for prostate cancer and data from one case-study conducted in a woman with confirmed PCOS) is that during the time women receive flaxseed supplementation they will experience reduced serum levels of testosterone, and total and LDL cholesterol, as well as clinical evidence of hirsutism. Given the pilot nature of this study, statistical analyses will be limited to simple descriptive statistics. We have observed no negative side effects, other than minor gastro-intestinal occurrences (i.e., temporary increased flatulence, borborygmi, increased number of stools, etc.) associated with flaxseed supplementation in our previous studies either with short or long-term use. Flaxseed supplementation will be discontinued if indicated and the events reported to the institutional review board.

This is a randomized control trial of acupuncture for women with polycystic ovary syndrome. The study is triple-blinded.
Polycystic Ovary Syndrome
The study will recruit 40 subjects with Polycystic Ovary Syndrome (PCOS) as defined by the NIH criteria. The subjects will be pre-screened for insulin sensitivity using fasting insulin and glucose levels and oral glucose tolerance test. The 20 most insulin resistant subjects will undergo measurements of in vivo insulin action by hyperinsulinemic, euglycemic clamp. Body composition will be measured by dual-energy X-ray absorptiometry (DEXA). Plasma lipids and markers of oxidative stress will be measured. They will then receive open label controlled release alpha lipoic acid (CRLA) at 800 mg twice daily for 16 weeks. After treatment hyperinsulinemic euglycemic clamps, DEXA, plasma lipids and markers of oxidative stress will be repeated. Hypotheses: LA will improve insulin sensitivity in PCOS subjects; LA will reduce oxidative stress, testosterone levels and improve cardiovascular risk factors.
Insulin Resistance, Oxidative Stress
The goal of this study is to determine the genetic basis of polycystic ovary syndrome (PCOS). We will first look for genes in the Icelandic population, where large family trees are known and it is easier to search for genes. We will then determine whether these same genes are important in U.S. PCOS patients.
