Filter by:Many, but not all, girls with high levels of the male hormone testosterone go on to develop polycystic ovary syndrome (PCOS) as adults. Women with PCOS often have irregular menstrual periods, excess facial and body hair, and weight gain. PCOS is also a leading cause of difficulty becoming pregnant. The investigators do not understand why some girls with high hormones develop PCOS and others do not. In a previous study by our group, some girls with high levels of male hormones had abnormalities in the secretion of another hormone, called luteinizing hormone (LH), that are often seen in women with PCOS. However, another group had normal LH secretion. The girls with the abnormal LH secretion had higher levels of another hormone, called insulin, than the girls with normal LH secretion. The investigators will test whether metformin, an insulin-sensitizing agent, changes the effects of high male hormone levels in adolescent girls, specifically by looking at their LH secretion response following metformin treatment.
GnRH (Gonadotropin-releasing hormone) antagonists in IVF (in vitro fertilization) has been accomplished by several randomized controlled trials compared with conventional GnRH agonist long protocol in polycystic ovary syndrome (PCOS) patients. Moreover, there are debating issues that refer to the timing of GnRH antagonist initiation. The purpose of this study is to investigate the laboratory and clinical priority during ovarian stimulation for IVF in patients with PCOS treated with three different protocols.
PCOS is a disorder which is characterized by hyperandrogenism (high serum male hormone levels), ovulatory dysfunction, and polycystic ovaries (multiple follicles-over 12- in the ovary). There is no universally accepted definition for PCOS. The Rotterdam criteria require 2 of 3 criteria for diagnosis, including hyperandrogenism (clinical hirsutism or serum hormone measurement), oligomenorrhea/amenorrhea, and ultrasound findings of polycystic ovaries. This study is a prospective randomized pilot study designed to evaluate the effects of flaxseed supplementation (with Brevail) on hormonal and lipid metabolism balance in polycystic ovarian syndrome (PCOS) patients.
In the present study, serum chitotriosidase activity and its relationship with insulin resistance were determined in patients with Polycystic Ovary Syndrome (PCOS).
An association of the single nucleotide polymorphism (SNP) in the promoter gene that codify for 17b-HSD5 enzyme (71A>G) with polycystic ovary syndrome (PCOS) and hyperandrogenemia has been suggested in previous studies. Given the role of 17b-HSD5 in androgenic metabolism producing testosterone from precursors, the investigators hypothesis is that women with PCOS and with the variant allele G have a poor response on hirsutism and on hormonal and metabolic variables after oral contraceptive pill (OCP) treatment for 6 months.
There have been some controversies regarding the use of preparations with LH activity in patients with polycystic ovary syndrome (PCOS) who have high endogenous LH activity. In this research we aimed to compare urinary menotrophin versus recombinant FSH (rFSH) with respect to the prevention of OHSS
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.
The prevalence of preterm birth is rising in most western countries. The causes of preterm birth is not fully understood and seem to be multifactorial. The endocrine and metabolic aspects are scarcely investigated.The main purpose of this study is to test the hypothesis that endocrine and metabolic factors associate to preterm births.
To study the clinical and biochemical characteristics women with polycystic ovary syndrome (PCOS) in different aged groups.
Between 40% and 85% of women with Polycystic Ovary Syndrome (PCOS) are overweight or obese and obesity is closely linked to the development of PCOS. Although it is well established that obesity increases the severity of the clinical features of PCOS, data regarding the prevalence of PCOS in obese women and the change in body weight in women with PCOS over time are scares. In a prevalence study it was investigated whether obesity increases the risk of PCOS in the general population and they demonstrated that the prevalence rate of PCOS in underweight, normal-weight, overweight, and obese women were 8.2, 9.8, 9.9, and 9.0%, respectively, similar to that observed in the general population. These results suggest that the risk of PCOS is only minimally increased with obesity. On the other hand, in a Spanish prevalence study among overweight and obese subjects, they demonstrated a 28.3% prevalence of PCOS, which is markedly higher compared with the 5.5% prevalence of PCOS in lean women in Spain. First the investigators aim to estimate the prevalence/probability of PCOS among obese, premenopausal women (between 18 and 50 years) with no symptoms of classic menopausal symptoms in Sweden. Secondly, to elucidate whether women diagnosed with PCOS respond to standard weight reduction regime to the same extent as women without PCOS.
