Adding L-Carnitine to Clomiphene Citrate for Induction of Ovulation in Women With Polycystic Ovary...
Polycystic Ovary SyndromePolycystic ovary syndrome is one of the most common endocrine disorders, affecting about 6-10% of women in their reproductive age. Anovulation and hyperandrogenism are often present together with hyperinsulinaemia and insulin resistance
Optimisation of Follicular Recruitment in IVM Cycles
InfertilityFemale1 moreThe study will focus on important aspects related to follicle recruitment using exogenous gonadotropins in patients with polycystic ovaries: Early follicle recruitment in patients with polycystic ovaries using corifollitropin alfa: does administration of this drug result in earlier and higher FSH (follicle stimulating hormone) concentrations above the threshold for follicle recruitment in an IVM (in vitro maturation) cycle preceded by oral contraceptive suppression, in comparison to normal daily administration of rFSH (recombinant follicle stimulating hormone, Puregon)?; The maturation rate of the obtained oocyte-cumulus complexes in standard IVM media registered for clinical use: does stimulation with corifollitropin alfa versus recombinant FSH have an impact on the maturation rate and developmental capacity of the oocytes ?
Ovarian Stimulation and Intrauterine Insemination in Women With Polycystic Ovarian Syndrome
InfertilityPolycystic Ovarian Syndrome1 moreThe study null hypothethesis is: intrauterine insemination (IUI) does not improve pregnancy rates in women with polycystic ovary syndrome. Infertile women with pcos will receive gonadotropins for ovarian stimulation and then randomize to either IUI or timed intercourse (TI)
Oral Administration of DCI to Women With PCOS
Polycystic Ovary SyndromeTo determine if oral DCI administration to women with PCOS increases the total DCI content in urine and blood, and, if so, if that change is accompanied by i) an increase in DCI-IPG release in blood (as determined by bioactivity) during an oral glucose challenge and ii) an increase in whole-body insulin sensitivity.
Single Ascending Dose, First-in-Human Study on Safety, Tolerability and Pharmacokinetics of BAY1161116...
Polycystic Ovary SyndromeThis study will be conducted in a single center, double-blind with 6 dose escalation groups to evaluate the safety, tolerability, and pharmacokinetics of single ascending doses of BAY1161116.
Evaluation of Oral Lipid Ingestion in Relation to Ovarian Androgen Secretion in Polycystic Ovary...
Polycystic Ovary SyndromeThe 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.
Effects of Androgen Blockade on Sensitivity of the GnRH Pulse Generator to Suppression by Estradiol...
Polycystic Ovary SyndromeHyperandrogenismThe purpose of this study is to understand the effects of elevated male hormones in adolescent girls and how they effect the development of polycystic ovary syndrome (PCOS). If the investigators understand the effects of elevated male hormones levels in girls, the investigators may be able to better treat girls with elevated male hormone levels and perhaps even learn how to prevent the development of PCOS. Females with elevated levels of male hormones respond differently to estrace (estradiol) and progesterone than females with normal male hormone levels. The investigators will be giving you estrogen and progesterone to see how you respond after the male hormone has been blocked by a medication called flutamide.
Assessment of Sensitivity of the Hypothalamic GnRH Pulse Generator to Estradiol and Progesterone...
HyperandrogenemiaPolycystic Ovary SyndromeGonadotropin-releasing hormone (GnRH) is a hormone that regulates the ability of the pituitary to secrete two hormones, luteinizing hormone (LH) and follicle-stimulating hormone (FSH). LH and FSH control the production of female hormones (such as estrogen and progesterone) and the development of eggs by the ovary. Progesterone and estrogen then decrease the number of GnRH pulses produced by the brain (and therefore the number of LH pulses from the pituitary). The ability to decrease GnRH pulses seems to be very important for normal menstrual function in adult women. The purpose of this study is to learn more about how GnRH and LH pulses are controlled during puberty. The information gathered in this study will hopefully allow us to learn more about how menstrual cycles are normally established in girls during puberty.
Effects of Flutamide on Insulin and Glucose Metabolism in Women With Polycystic Ovary Syndrome
Polycystic Ovary SyndromePolycystic 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.
Incretin Secretion in Women With Polycystic Ovary Syndrome (PCOS)
Polycystic Ovary SyndromeThe incretin hormones are secreted from the gastrointestinal tract in response to nutrient ingestion, and are responsible for 70 % of insulin secretion in response to glucose. The incretin response is attenuated in subjects with type 2 diabetes and other conditions associated with insulin resistance. Polycystic ovary syndrome (PCOS) is characterised by irregular periods and increased androgen levels. It is the most common endocrine disorder amongst young women at fertile age, and the most common cause of female infertility. Insulin resistance plays an important role in the development of the disease, and women with PCOS are at increased risk of developing tyoe 2 diabetes. the incretin hormones have not previously been investigated in women with PCOS, and the purpose of the present study was to investigate the secretion of the two most important incretin hormones Glucose-like peptide-1 (GLP-1) and Glucose dependent insulinotropic peptide (GIP) during a three hour oral glucose tolerance test.
