View clinical trials related to Menstrual Irregularity.
Filter by:The Covid-19 pandemic has impacted healthcare workers physically and psychologically. The aim of this study is to examine whether there is a change in menstrual cycle characteristics during pandemia. The aim of this study is to investigate whether there is an association between covid infection and menstrual cycle changes.
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.
The investigators would like to determine how aspects of adiposity and age influence ultrasound features of the ovaries which are used to diagnose polycystic ovarian syndrome (PCOS). The study will also compare anti-Müllerian hormone (AMH) levels against ultrasound features of the ovary to predict PCOS.
The investigators would like to determine how aspects of metabolism and age influence ovarian function. The purpose of the study is to understand how nutrition and metabolism relate to follicle development in women with regular cycles, irregular cycles, or polycystic ovary syndrome (PCOS). We also plan to identify lifestyle factors associated with PCOS and understand how diet and activity levels impact features of PCOS.
Previous studies have demonstrated that Myo-inositol is capable of restoring spontaneous ovarian activity, and consequently fertility, in most patients with PCOS. The aim of our study is to investigate the role of folic acid conteined in the inositol preparation. The study group included 50 patients, randomly allocated to subgroup A (myo-inositol 1500 gr) and subgroup B (myo-inositol 2000 gr + folic acid 200 mcg). The investigation include menstrual pattern and hirsutism score evaluation, hormonal assays, oral glucose tolerance test, euglycemic hyperinsulinaemic clamp and lipide profile at baseline and after six months of treatment.
The purpose of this study is to examine the effects of increased food intake on the menstrual cycle and bone health in physically active women who have irregular or absent menstrual cycles. This study will examine whether a 12 month period of increased food intake will cause menstrual cycles to resume and help bones get stronger.
