Effect of High Testosterone on Sleep-associated Slowing of Follicular Luteinizing Hormone (LH) Frequency in Polycystic Ovary Syndrome

During the follicular phase of the normal menstrual cycle, luteinizing hormone (LH) pulse frequency decreases during sleep. These decreases may be important to support follicle stimulating hormone (FSH) synthesis and secretion. Polycystic ovary syndrome (PCOS) is associated with a persistently rapid gonadotropin hormone-releasing hormone (GnRH) pulse frequency, an abnormality that ...

Effect of Metformin on Adrenal or Ovarian Androgen Production in Overweight Pubertal Girls With Androgen Excess

This study will test whether metformin administration can ameliorate androgen (male hormone) overproduction in overweight pubertal girls with androgen excess. The investigators hypothesize that improvement in insulin sensitivity by 12 weeks of metformin administration will improve androgen levels after adrenal stimulation testing with adrenocorticotropic hormone (ACTH) or ovarian stimulation testing ...

Phase N/A

Suppression of Daytime and Nighttime Luteinizing Hormone Frequency by Progesterone

Studies will be performed in early pubertal (late Tanner 1 [estradiol level > 20 pg/ml] to Tanner 3, premenarcheal) girls with and without hyperandrogenemia (HA). After a potential subject is identified by the Pediatric, Teen, or Endocrine clinics, she will come to the CRU or alternate UVA clinical unit for ...

Urinary DENND1A.V2 as a Predictor of Pubertal Hyperandrogenemia

To date, the mechanisms underlying excess androgen production from steroid producing tissues have been unclear, but recent Genome Wide Association Studies (GWAS) have provided additional data in this regard. Initial GWAS data in a Han Chinese population identified some 12 loci as potential PCOS susceptibility gene candidates. One of these ...

Phase N/A

Ovarian Contribution to Androgen Production in Adolescent Girls

Adolescent hyperandrogenemia can represent a forerunner to adult PCOS. Because adrenarche leads to an increase in adrenal androgen production during early puberty and since early puberty is associated with an overnight rise in testosterone that follows a similar time course to cortisol, we hypothesize that the adrenal gland is a ...

Phase N/A

OCP vs Metformin for Improvement in Clinical Symptoms and Metabolic Markers in Indian PCOS Women

Objective: To assess effectiveness of ISD (Insulin sensitizing drugs) Vs OCP (Combined E&P cyproterone acetate) in improving clinical, hormonal and metabolic features of PCOS( polycystic ovary syndrome)women from India. Intervention Randomized to receive Metformin 1500 mg / day OR OCP (EE+CA) Life style advice to women with BMI ( body ...

Phase N/A

Etiological Factors of Obesity-Associated Hyperandrogenemia in Peripubertal Girls

A number of pathophysiological mechanisms underlie the polycystic ovary syndrome (PCOS). Neuroendocrine abnormalities play a significant role in most women with PCOS, and PCOS is associated with relative resistance of the gonadotropin releasing hormone (GnRH) pulse generator to negative feedback by progesterone and estradiol. This hypothalamic resistance to negative feedback ...

Phase N/A

Evaluation of Adrenal Androgens in Normal and Obese Girls After Suppression and Stimulation

We propose that the adrenal gland is the predominant source of the early morning rise in progesterone and testosterone which is more marked in early puberty. Specifically, we hypothesize that dexamethasone administration at 22:00 will be associated with a dampened progesterone and testosterone rise the subsequent morning in normal girls. ...

Phase N/A

Effect of Metformin Therapy on Serum Under-carboxylated Osteocalcin Levels in Hyperandrogenic Lean Polycystic Ovarian Syndrome Women

Under-carboxylated osteocalcin (ucOC), the precursor substrate of bone biomarker OC is a potent regulator of energy metabolism by promoting insulin production and adiponectin synthesis and decreasing fat stores.UcOC has a potential role in the physiopathology of polycystic ovary syndrome (PCOS), a common disorder defined by the constellation of anovulation, insulinresistance, ...

Phase

The Mechanism of Modified Utral-long Protocol in Improving Endometrial Receptivity in Patients With PCOS and IR

The endometrial biopsy was performed in the previous cycle of the protocol. According to the expression of NF-B in the endometrium random group. The difference of NF - B expression in patients with different protocol were compared.
