Urinary DENND1A.V2 as a Predictor of Pubertal Hyperandrogenemia
Polycystic Ovary SyndromeHyperandrogenism1 morePolycystic ovary syndrome (PCOS) is a common disorder marked by hyperandrogenism, oligo-/anovulation, and subfertility. The precise causes of PCOS are unclear, but the pathophysiology involves complex genetic and environmental influences. Importantly, not all girls with obesity have HA, and free testosterone (T) concentrations are highly variable in this group. Luteinizing hormone (LH) and insulin concentrations are significant but only partial predictors of free T in girls with obesity; significant unexplained variability in free T suggests that additional factors contribute to HA in this population. Abnormalities of ovarian and adrenal steroidogenesis are likely contributors in this regard, but such abnormalities are difficult to quantify. Recent Genome Wide Association Studies have identified DENND1A as a PCOS susceptibility gene candidate. Preliminary in vitro data strongly implicate a DENND1A splice variant called DENND1A Variant 2 (DENND1A.V2) as a contributor to excessive theca cell androgen production in PCOS. The investigators' primary goal with the proposed pilot study is to determine the relationship between urinary exosomal DENND1A.V2 mRNA and free T concentrations in peripubertal girls. The investigators hypothesize that urinary exosomal DENND1A.V2 mRNA quantity is a significant and independent predictor of peripubertal hyperandrogenemia. In this study, the investigators will carefully phenotype peripubertal girls with and without hyperandrogenemia (primarily in the form of hormonal, maturational, and anthropometric measurements) in addition to measuring urinary exosomal DENND1A.V2 mRNA. As a primary analysis, the investigators will examine the relationship between morning free testosterone and urinary exosomal DENND1A.V2, controlling for previously-described partial predictors of free testosterone (LH, insulin) in addition to potential confounders (BMI z-score, bone age). These studies will provide important information regarding the etiology of HA in peripubertal girls. Ultimately, these data may lead to a non-invasive test of ovarian/adrenal steroidogenic activity and support the development of a diagnostic test for PCOS in high-risk peripubertal girls (e.g., those with obesity).
Clomifene Citrate Versus Metformin in First-line Treatment of Infertility in Patients With Polycystic...
Polycystic Ovary SyndromeInsulin ResistanceThe results of studies conducted until now does not determine what the best way to treat infertility in the first line with patients with Polycystic ovary syndrome (PCOS). This study objective is to determine the best treatment for such patients. The long-term consequence health of women with PCOS are multiple. The woman with PCOS has a risk of developing metabolic diseases, heart diseases, diabetes Type II or anovulatory infertility. The insulin resistance plays an important role in all this medical condition. Clomiphene Citrate (CC) remains the first line treatment to induce ovulation in women with PCOS and anovulatory infertility.
Clinical Sciences Research Proposal- The Effect of Physical Exercise on PCOS Overweight Female Adolescents...
Polycystic Ovary SyndromeOverweightThe Poly Cystic Ovary Syndrome (PCOS), is one of the most common reasons for subfertility, oligomenorrhea and amenorrhea. With the occurrence of 6-20% of the general adult women population. One of the main criteria of this syndrome is a hyper androgenic state. More than 50% of women who have PCOS are overweight. In the teenage population, PCOS is common in 5-10% of teenage girls. A recent research has shown that elite athlete teenage girls have higher serum androgen levels, especially in anaerobic types of sport. The purpose of this experiment is to examine the reaction of teenage PCOS overweight girls towards anaerobic exercise. To determine if their hyperandrogenic state is more adapted to excel in anaerobic exercise compared to teenage overweight girls without PCOS.
Letrozole for Frozen Embryo Transfer (FET) in Patients With Polycystic Ovary Syndrome (PCOS)
InfertilityFemale3 moreTo offer patients with oligomenorrhoea or amenorrhoea an alternative to frozen embryo transfer in an artificial cycle, endometrial preparation using letrozole may be a valuable option. Letrozole, a potent, reversible nonsteroidal aromatase inhibitor with relatively short half-life, can successfully induce ovulation without any adverse anti-estrogenic effects and thus without affecting the endometrium. The use of letrozole typically results in monofollicular growth and this reduces the effect of supraphysiological levels of estrogen on the endometrium and embryo. The purpose of this study is to compare a frozen-thawed embryo transfer in an artificial cycle with a letrozole-induced ovulatory cycle, specifically in PCOS patients. The primary outcome is early pregnancy loss.
Vitamin D Levels in Women With Polycystic Ovary Syndrome
Polycystic Ovary SyndromePolycystic ovary syndrome is the commonest endocrinopathy among women of reproductive age. Its worldwide prevalence has been estimated between5-10%. Vitamin D, a fat-soluble vitamin, can be produced in two ways: by intestinal absorption and endogenous synthesis from a precursor of 17-hydroxyl cholesterol on the skin with sufficient exposure to ultraviolet sunlight.

Endocrine System DiseasesGonadal DisordersThe purpose of this study is to compare the effectiveness of low dose human chorionic gonadotropin (HCG) in combination with clomiphen citrate to induce ovulation and its endocrine response in patients who had previously failed to ovulate on clomiphen citrate alone. The investigators will also compare the effectiveness and endocrine response of this approach with the regimen of adding HMG to clomiphen citrate.
Clomiphene Citrate in Infertile PCOS Patients
Polycystic Ovary SyndromeInfertilityAnovulatory infertility is a common feature of the polycystic ovary syndrome (PCOS). Clomiphene citrate (CC) represents the first therapeutic option for treating the anovulatory infertility in PCOS patients because it is characterized by low costs, limited dose-dependent side effects, and simplicity of administration and management due to no need for ongoing monitoring. Excellent results in terms of ovulations have been obtained using CC. However, only 50% of patients who ovulates under CC will conceive. The exact explanation for the discrepancy between the ovulation and pregnancy rates is unknown, but several hypotheses on the anti-estrogenic effects that CC exerts on the ovary and uterus have been suggested. To date, few data are available on the optimal schedule for CC administration, and it is unknown how long patients who ovulate under CC should continue treatment before switching to second-line ovulation induction therapy. The aim of the study was to define the clinical benefits of CC administration according to its duration of administration.

EvaluationsDiagnostic Self1 morePolycystic ovary syndrome (PCOS) is a heterogeneous disorder of reproductive, endocrine and metabolic functions. Vitamin D has an influence on metabolic and reproductive functions. This study was designed to explore the levels of free 25 hydroxy cholecalciferol [25(OH) D] in PCOS patients. We also aimed to clarify the impact of vitamin D supplementation on cardiometabolic status, androgen profile and clinical features of PCOS.
The Effect of Fasting on ICSI Outcomes in Patients With Polycystic Ovary Syndrome
InfertilityPolycystic Ovary SyndromeDesign and protocol of PCO fasting research: This study is a pilot prospective, single-blinded (to the health assessor), randomized controlled trial conducted at the In Vitro Fertilization ( IVF) center of the Department of Obstetrics & Gynecology, Kasr El-Ainy Hospital, Cairo University, Egypt, from October 2018 to September 2019, to determine the clinical effect of fasting on ICSI outcomes in PCOS patients. Ethical committee approval was obtained. The study will include 100 infertile patients with PCOS diagnosed according to Rotterdam criteria of PCOS and who are candidates for ICSI cycle. Women with diabetes, thyroid disorder or other endocrine dysfunctions, uterine abnormalities were excluded. All patients are informed about the study and consent is given by those who accept to participate. Careful history taking include infertility type, duration , cause, obstetric history, medical and surgical history and demographic distribution is taken. Full physical examination and 2 dimensional (2D) transvaginal sonography (TVS) are done on day 2 to 5 of menses to assess antral follicle count, uterus and adnexa . Body mass index (BMI) and waist/hip ratio (WHR) are calculated, Blood samples are taken for Fasting insulin , fasting plasma glucose, Homeostatic model assessment (HOMA index), lipid profile and hormonal profile are done. All 100 participants will be randomized withdrawing closed envelopes for each patient into group A and group B . Group (A): patients will have periodic fasting for 4 weeks prior to the treatment cycle. The fasting method involves daily fasts of 14-16hours and restrict eating to an 8-10 hour "eating window" as 2-3 or more meals of balanced diet. Group (B): no fasting, patients will have usual balanced diet as 3 meals and 2 snacks all over the day. Both groups should take adequate water and non calorie beverages intake daily (2-3 liters) Subjects are instructed to wait for spontaneous menses, or to be prescribed progestins orally (as Norethisterone 5mg) twice daily for 21 days starting from the fifth day of menses. Patients should continue taking oral metformin 500-1000 mg daily, until confirmation of pregnancy. The next visit is scheduled on day 2 of next cycle when transvaginal ultrasound is done to confirm that endometrial thickness <5mm, no ovarian cyst by ultrasound. Body mass index (BMI) and waist/hip ratio (WHR) are calculated. Blood samples are taken for Fasting insulin , fasting plasma glucose, Homeostatic model assessment (HOMA) index, lipid profile ( Triglycerides (TGs), total cholesterol, High density Lipoprotein (HDL), Low density Lipoprotein (LDL), free and total testosterone , Sex Hormone Binding Globulin (SHBG), Free Androgen index (FAI), AntiMullerian Hormone (AMH), Basal Follicle Stimulating Hormone (FSH), Luteinizing Hormone (LH), Estradiol (E2),and then antagonist protocol is followed. Gonadotropins as Intramuscular (I.M.) injections of 150-300 (International units) I.U. of highly purified Human Menopausal Gonadotropins daily (Merional, 75 I.U. /vial, IBSA). and Urofollitropin or highly purified human follicle stimulating hormone(Fostimon®, 75 I.U. /vial, IBSA) are give in a ratio of 1:1.The dose is adjusted according to the age, BMI, Antral follicle count (AFC), serum levels of AMH, FSH and ovarian response. Fixed antagonist protocol is given and follow up until embryo transfer(ET). Quantitative ß- HCG in serum after is done after 14 days of embryo transfer.TVS is performed to detect clinical pregnancy at 6-7 weeks of gestation. Primary outcome is clinical pregnancy rate per cycle. Secondary outcomes include Body mass index (BMI) and waist/hip ratio (WHR), fasting insulin , fasting plasma glucose, Homeostatic model assessment (HOMA) index, lipid profile and other ICSI outcomes.
Progesterone Action on Endometrium of PCOS
Polycystic OvaryProgesterone ResistanceObjective: To study the influence of metabolic factors on the action of progesterone on the endometrium of women with PCOS. Design: A prospective open-label clinical trial. Setting: Participants were recruited from an outpatient reproductive endocrinology clinic at an academic tertiary medical care center from 2014 to 2019. Subjects: To assess the sole effect of progesterone (P4) on the endometrium we studied amenorrheic (cycles> 90 days) women with PCOS (n=23), comparing them to healthy eumenorrheic control women ( n=13). Intervention(s): All subjects underwent an endometrial biopsy (EB) in the follicular phase of the first study cycle. They were then treated with micronized P4 (400 mg/day x 10 days intravaginally) from days 14-28 of the cycle, and a second EB was performed between days 20-24 of the cycle (second phase). Main Outcome Measure(s): EB samples were analyzed under light microscopy for histomorphometric analysis.
