Filter by:Recent studies have shown that C natriuretic peptide is produced from granulosa cells, increasing cumulative guanosine monophosphate (cGMP) production by affecting cumulus cells through natriuretic peptide receptors. It is suggested that produced cGMP maintains the transport of oocytes via the gap junctions and leads to a continuous increase in cyclic adenosine monophosphate (cAMP) levels in the oocyte. An important role of increased internal cAMP levels in the oocyte is shown to suppress meiotic progression. Deoxyribonucleic acid studies in animals have shown that expression of the natriuretic peptide precursor increases during the periovulatory period and shows that this increase decreases rapidly after luteinizing hormone / human chorionic gonadotropin (hCG) stimulation.Human studies have shown that after ovulation induction, the CNP level in follicular fluid decreases following ovulatory dose of hCG.Polycystic ovary syndrome (PCOS) is the most common endocrine disease in the reproductive period, characterized by hyperandrogenism, oligo-anovulation, and polycystic ovarian morphology on ultrasonography, and in an animal study investigating the relationship between CNP and PCOS, serum CNP levels were increased in polycystic ovary syndrome.CNP serum level is thought to show differences between healthy women and women with polycystic ovary syndrome.
Polycystic ovary syndrome (PCOS) is the most common endocrinopathy affecting women of reproductive age It is hypothesized that ∼20 fold increase in reactive oxygen species (ROS) generation in Follicular fluid (FF) and granulosa cells of PCOS women plays an adverse role in affecting the IVF success rate. Astaxanthin (3,3'-dihydroxy-β,β'-carotene-4,4'-dione) is a nonprovitamin A carotenoid classified as a xanthophyll and is found in high amounts in the red pigment of crustacean shells (e.g., crabs, shrimp), salmon, trout, and asteroides. It has been demonstrated that astaxanthin displays a wide variety of biological activities, including anti-oxidative, anticancer, and anti-inflammatory effects. investigators aim to investigate the effect on Astaxanthin administrating on reducing of ROS in FF and induction of antioxidant response elements in PCOS women.
The goal of this proposal is to pilot test our existing very-low carbohydrate diet intervention, adapted for women with PCOS.
This study will assess the potential impact of elagolix on disordered pituitary and ovarian hormones in women with polycystic ovary syndrome (PCOS).
The effect of Lactobacillus rhamnosus supplementation on body weight, hyperandrogenism and insulin resistance in overweight and obesity women with Polycystic Ovary Syndrome will be analysed.
Purpose: This study aimed to compare the ocular surface disease test results, anterior segment parameters, and ocular response analyzer (ORA) findings of polycystic ovary syndrome (PCOS) patients with those of healthy reproductive age female controls.
The purpose of this study is to understand the experience of living with polycystic ovary syndrome (PCOS) as an active duty Service Woman. As part of a budding research program, this proposed study will lay the groundwork for future intervention studies targeting the management of PCOS in a military population.
This study is a randomized controlled clinical trial to compare the pregnancy outcomes of mild and minimal stimulation in infertile women with polycystic ovarian syndrome. The study population consisted of all infertile women with polycystic ovary syndrome based on Rotterdam criteria who have not succeed to achieve fertility despite multiple treatments such as drug therapy, laparoscopic surgery, and the frequent failure of induction therapy using gonadotropins and are now candidate for in vitro fertilization (IVF) or intra cytoplasmic sperm injection (ICSI) in Reproductive Biomedicine Research Center, Royan institute, Tehran Iran.
Women with at least one uterine leiomyoma and polycystic ovary syndrome over 10 mm and women with normal ultrasonographic findings were included in the study. Blood samples were taken for biochemical analysis such as vitamin D, calcium, magnesium, phosphorus, thyroid stimulating hormone (TSH), hemoglobin (hb), hematocrit (htc), platelet (plt), and albumin. The study groups were compared in terms of these biochemical markers and family history of patients, daily sunshine hours, clothing preferences and education level.
Ninety women with PCOS candidate for ICSI were randomized to 2 groups:Group A: fresh samples of PCOS patients undergoing IVF (no= 45) and Group B: frozen samples of PCOS patients undergoing IVF (no= 45). Morphologically good embryos will be cultured in a culture dish and the supernatants will be collected freshly from culture system at day 3 and stored at -20 ̊ c until being tested. Morphologically good embryos scheduled for freezing will be cryopreserved for less than one year and thawed, the supernatant will be collected and stored at -20 ̊ c until being tested. Quantification of mtDNA in fresh and frozen culture media using qPCR technique.The template DNA prepared and the dilution standards prepared will be used for qPCR to determine the amount of MtDNA and nuclear DNA in the sample using QuantiTect SYBR Green PCR Kit
