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.
Thyroid hormones (TH) can modify the functioning of the hypothalamic-pituitary-ovarian axis, affecting the functions of granulosa cells and the development and apoptosis of preantral follicles. TH receptors are present within the oocytes, and TH and anti-thyroid antibodies (ATA) are present in the follicular fluid. Improper thyroid function can cause ovulation disorders, luteal phase failure, impaired endometrial receptivity and result in implantation failures and recurrent miscarriages. While overt hypothyroidism is treated to improve fertility, the effect of subclinical hypothyroidism (SCH) and the presence of circulating ATAs on fertility and obstetric outcomes is uncertain and data on ovarian reserve rates are conflicting. Among the causes of ovulation disorders (group II according to the WHO classification), polycystic ovary syndrome (PCOS) dominates, found in 3-15% of women of reproductive age, and the remaining group of causes is the so-called Hypothalamic-Pituitary-Ovarian Axis Dysfunction (HPOD). The exact etiology of both entities is unknown.
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 study evaluates the addition of clomiphene citrate (CC) to letrozole for the treatment of infertility in women with polycystic ovary syndrome across a course of two treatment cycles with stair step dosing of letrozole similar to standard of care. Half of the participants will receive letrozole and CC in combination, while the other half will receive letrozole alone.
This exploratory study investigates fasting as a potential supportive therapy in infertility treatment for women suffering from infertility
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.
PCOS is a complex disease that is diagnosed by the presence of two of the following three: oligo/anovulation, clinical and/or biochemical hyperandrogenism, or polycystic ovaries by ultrasound . PCOS affects 4% to 21% of females in reproductive age . Although subfertility is abundant in women with PCOS, a majority of these women will achieve pregnancy naturally or by treatment. Different treatment modalities are present for ovulation induction. Life style modifications including weight loss are encouraged for those who are overweight or obese. Pharmacological induction of ovulation represent the first line therapy for induction of ovulation. Options include aromatase inhibitors (Letrozole), Clomiphene Citrate (CC) or Metformin, alone or in combinations. For second line treatment either Gonadotropins (Gn) or laparoscopic ovarian surgery (LOS) are the recommended options . the objective of the trial is to study the effectiveness and safetey of surgical induction of ovulation strategy and compare it to medical induction strategy with Gonadotropins
The purpose of this study is twofold: First, to see if elagolix can suppress gonadotropin and ovarian hormones in the short-term period, when only administered for a 72-hour period. If elagolix effectively suppresses gonadotropin and ovarian hormones in a timely manner, it could be used to alter aspects of the menstrual cycle, depending on when administered. Second, is there a window for when elagolix functions best? While other studies initiate elagolix at the start of a woman's menstrual cycle, investigators of this study want to determine if administering elagolix at various points in a woman's menstrual cycle alters its ability to suppress gonadal and ovarian hormones.
To determine if Inositol, a dietary supplement, will improve ovarian and adrenal androgen excess in women with Polycystic Ovarian Syndrome(PCOS).
