Filter by: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.
Polycystic Ovary Syndrome (PCOS) is very common, affecting approximately 5% of women of reproductive age, and impacts not only on quality of life, but also has long-term health consequences for many sufferers, such as increased risks of developing Type II diabetes, cardiovascular disease and cancer of the womb. The symptoms that may occur such as irregular periods; lots of body hair; thinning hair on scalp, obesity and infertility, can also lead to poor self-esteem. Whilst treatments can help fertility, other treatments to correct the other symptoms are less successful. Alternative methods to regulate periods would be helpful, especially ones which avoid the long-term use of steroids in patients who may already be overweight. Reflexology is poorly represented in scientific papers, with nothing published regarding reflexology and its effect upon PCOS. However patients who use reflexology report more regular periods, thicker hair on scalp and greater wellbeing. Therefore we aim to investigate the effect of reflexology on: 1. The menstruation cycle (normal being every 21-35 days). 2. Imbalances in hormone, insulin and blood sugar levels associated with PCOS. 3. Other problems associated with PCOS such as thinning hair on scalp, excessive body hair, and obesity. 4. Quality of life. Government and NHS agendas agree that if there's evidence of an effective complimentary therapy the NHS should provide it. Therefore the results may have an influence on the care pathways of patients with PCOS towards a more holistic, patient centred and empowered approach. It is also non invasive and liable to result in higher patient satisfaction regarding their treatment. This research may also inform policy makers so that complementary medicine provision is provided on a wider basis within the NHS, which at the moment is dictated by the individual Trust's budget allocation. However this research could save money overall as in America, the yearly cost of treating PCOS is $4.36 billion.

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 Ovary Syndrome (PCOS) is the major cause of infertility in the United States. Many women with PCOS demonstrate insulin resistance and a compensatory hyperinsulinemia.This is due to both an intrinsic form of insulin resistance unique to PCOS and, in many cases, acquired insulin resistance due to obesity. The importance of this observation lies in the fact that hyperinsulinemia appears to play an important pathogenetic role in the hyperandrogenism and anovulation of both obese and lean women with PCOS.
The primary research hypothesis is that ovulation induction with an aromatase inhibitor (letrozole) is more likely to result in live birth than ovulation induction with a selective estrogen receptor modulator (clomiphene citrate) in infertile women with PCOS. A safety hypothesis will also be incorporated into the primary research hypothesis in which we hypothesize both treatments are equally safe for mother and child. Secondary research hypotheses include: 1. Treatment with letrozole is more likely to result in singleton pregnancy compared to treatment with clomiphene citrate. Singleton pregnancy is defined as presence of a single intrauterine gestational sac with a single fetal pole and observable heart motion. 2. Treatment with letrozole will less likely result in a first trimester intrauterine fetal demise than treatment with clomiphene citrate. A first trimester IUFD is defined as a pregnancy that ends before 13 weeks gestation. 3. Treatment with letrozole is more likely to result in ovulation (increased ovulation rate) compared to treatment with clomiphene citrate. Ovulation is defined as a midluteal progesterone level ≥ 3 ng/mL. 4. The shortest time to pregnancy will be with letrozole. 5. Age, body mass index, SHBG, testosterone, LH, Anti-Mullerian Hormone (AMH), and degree of hirsutism and acne will be significant predictors of ovulation and conception regardless of treatment. 6. Improvement in SHBG, testosterone, AMH, and LH levels will be significant predictors of ovulation and conception regardless of treatment. 7. DNA polymorphisms in estrogen action genes will predict response to study drug. 8. Quality of Life will be better on letrozole than clomiphene. 9. Letrozole will be more cost effective at achieving singleton pregnancies than clomiphene.
A 24 week study to compare the use of Metformin, birth control pills and a carefully planned intensive lifestyle program that includes weight loss and exercise. These approaches will be compared to placebo (a pill that contains no active substances. Metformin, birth control pills and the lifestyle management program will be used on this research study to compare their ability to: 1. reduce fasting glucose levels 2. reduce androgen hormone levels 3. improve sex steroid binding, and 4. improve lipids (fatty substances in the blood)
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.
1. The polycystic ovary syndrome is the major cause of infertility in the United States. Metformin has been shown to increase frequency of ovulations in PCOS, and is used in clinical practice to treat infertility, but some women with PCOS do not respond to metformin treatment. 2. Knowing that a specific gene predicts the effect of metformin on ovulation would facilitate more efficient and effective treatment of infertility in PCOS.
The purpose of this study is to look at the metabolic (use of energy) and hormonal features of sleep problems in women with polycystic ovary syndrome (PCOS).
