View clinical trials related to Anovulation.
Filter by:Group II causes of anovulation according to the World Health Organization include polycystic ovary syndrome (PCOS) and the less common dysfunction of the hypothalamic-pituitary-ovarian axis (HPOD). Assessment of ovarian volume, number and morphology of ovarian follicles is essential in the diagnosis of menstrual disorders, including PCOS and HPOD. However, the uterus is a target organ for steroid hormones, and the assessment of uterine size and endometrial morphology may also be of clinical importance. While ultrasonographic features of the ovaries in PCOS have been described and constitute one of the diagnostic criteria for the syndrome (Rotterdam criteria), there is little data on uterine volume in women with PCOS and HPOD. The aim is to compare ultrasound i) uterine volume and ii) endometrial volume among women with PCOS and women with HPOD.
Among the causes of ovulation disorders (group II of anovulation according to the World Health Organization classification), the dominant one is polycystic ovary syndrome (PCOS), and the remaining cases are classified as Hypothalamic-Pituitary-Ovarian Axis Dysfunction (HPOD). The exact etiology of both entities is unknown. To diagnose PCOS, the Rotterdam criteria must be met and other conditions that may cause hyperandrogenism or ovulation disorders must be excluded. PCOS is more often accompanied by other endocrine and metabolic disorders, such as obesity, dyslipidemia, hyperandrogenism, insulin resistance, diabetes, hyperprolactinemia and thyroid diseases, as well as infertility due to ovulation defect. These conditions not only significantly reduce quality of life (QoL), but also lead to an increased risk of cardiovascular disease, metabolic syndrome, adverse obstetric outcomes and an increased risk of endometrial cancer, further impairing QoL.
This is a randomized controlled trial comparing density gradient centrifugation and microfluidic sperm sorting in patients undergoing intrauterine insemination to evaluate cumulative pregnancy outcomes.
This is a randomized double-blind controlled trial on the effect of vitamin D supplementation to assess the ovulation rate of women with polycystic ovary syndrome (PCOS) and other reproductive, endocrine and metabolic outcomes after one year of treatment.
To determine if Inositol, a dietary supplement, will improve ovarian and adrenal androgen excess in women with Polycystic Ovarian Syndrome(PCOS).
Through the COLA Study and Biobank the investigators hope to enable further identification of phenotype, endocrine, ethnic, and metabolic characteristics associated with menstrual cycle disturbances; and: the identification of genetic or other etiologic factors associated with cycle disturbances.
The purpose of this study is to evaluate the effect of concomitant administration of estradiol during use of clomiphene citrate (CC) for induction of ovulation in infertile women.
