Active clinical trials for "Polycystic Ovary Syndrome"

The aim of this work is to study the effect of metformin use for reducing early pregnancy loss in pregnant patients with Polycystic ovary syndrome (PCOS).

To investigate whether women with polycystic ovary syndrome who are post-partum excrete higher levels of sebum in comparison to healthy controls due to high levels of androgens.

Hormonal evaluation of women who are suspected of having Polycystic ovary syndrome (PCOS) involves the measurement of basal levels of androgens and 17-hydroxyprogesterone (17-OHP), which are generally used to establish the presence of hyperandrogenemia. In general, these levels are obtained during the follicular phase to maintain sampling uniformity and avoid spurious increases due to corpus luteum function. However, because most hyperandrogenic patients are oligo/amenorrheic, it is frequently necessary to administer a progestogen to induce withdrawal bleeding and properly time the blood sampling. Several medications have been described to properly induce withdrawal bleeding , with medroxyprogesterone acetate (MPA) being the most widely use. However, synthetic compounds as MPA do not replicate precisely the constellation of biologic activities of the parent hormone and results in a temporary, albeit clinically relevant, suppression in ovarian function and circulating androgen levels , in addition of several adverse side effects . In this study, it is hypothesized that the administration of natural progesterone vaginally, which will avoid hepatic first pass, may result in significantly less hormonal suppression. The authors test this hypothesis by prospectively determining the effect of vaginal micronized progesterone (OMP), administered for the induction of withdrawal bleeding, on the circulating androgen and 17-OHP levels in women with PCOS.

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.

The effects of a 16-week exercise training program on insulin resistance and adiposity in overweight/obese women with Polycystic ovary syndrome (PCOS).

FlowMet study is a "sub-study" of the PregMet study (registered in 2005). The aim of the FlowMet study is to register the possible effect of metformin on the blood flow of the uterine artery in pregnant PCOS women. The participants will be examined with ultrasound Doppler in gestational week 10-13: before and 3h after the first tablet intake of metformin/placebo and 10-14 days after inclusion in the trial blood flow in the umbilical artery and fetal cerebral artery in gestational week 24.

Several data demonstrated that both clomiphene citrate (CC) and metformin are two safe and valid first-step options to induce ovulation in infertile anovulatory PCOS patients. Notwithstanding a high percentage of patients ovulate under treatment, only ~40% and 60% of subjects obtain a pregnancy after CC and metformin, respectively. For these patients, controlled ovarian stimulation (COS) followed by intrauterine insemination (IUI) could be the next therapeutic step before assisted reproductive techniques since IUI improves significantly the fertility in couples with unexplained infertility. Furthermore, to date it is not defined if COS should be obtained using the same ovulatory agent (CC or metformin) or switching the treatment to gonadotropins. In this view, the aim of the present study will be to evaluate the best management of infertile PCOS patients ovulating after CC or metformin.

To investigate the effect of metformin on pregnancy complications and pregnancy outcome in the II. and III. trimester of pregnancy in women with polycystic ovary syndrome.

Polycystic ovary syndrome (PCOS) is the most common female endocrine disorder, affecting 7%-18% of reproductive-age women. Women with PCOS are at increased risk for a number of adverse physical and mental health outcomes. Often diagnosed during the challenging developmental period of adolescence (ages 14-18), current clinical practice guidelines fail to consider the life-long nature of effective PCOS self-management through sustained healthy lifestyle habits and may, in fact, contribute to maladaptive patterns of unsustainable strategies for weight loss in adolescents. The investigators are testing an integrated mindfulness-based healthy lifestyle intervention for adolescents with PCOS (Working to Optimize Wellness in Teens with PCOS [WOW]). The purpose of this study is to obtain data supporting preliminary efficacy of WOW on biological and mental health outcomes with adolescents diagnosed with PCOS.

the effect of ketofol, a combination of propofol and ketamine, on hemodynamics and airway response during induction of general anesthesia has been studied before. Its effect on the smoothness of extubation has not been studied before. In the present study; we aimed to assess the effect of ketofol on the smoothness of extubation as regards, airway response, sedation score during suction and extubation and hemodynamic changes comparing it with propofol for induction of general anesthesia.
