View clinical trials related to Premature Ovarian Failure.
Filter by:Premature ovarian failure (POF) is a clinical syndrome defined by loss of ovarian activity before the age of 40 years. POF is characterized by menstrual disturbance (amenorrhea or oligomenorrhea) with raised gonadotrophins and low estradiol. The prevalence of POF is 1-2%. Extracellular vesicles (EVs) are membrane-packed vesicles that are secreted by a variety of cell types, including T cells, B cells, dendritic cells, platelets, mast cells, epithelial cells, endothelial cells, neuronal cells, cancerous cells, oligodendrocytes, Schwann cells, embryonic cells, and mesenchymal stromal cells-derived (MSCs). MSCs-EV more stable and induce stronger signaling and are produced in higher concentrations than stem cells. They demonstrate no inherent toxicity, are not associated with any long-term maldifferentiation of engrafted cells or tumor generation, and carry no apparent risk of aneuploidy or immune rejection following in vivo allogenic administration.Several studies have evaluated the safety and possible efficacy of injection MSCs-EV for the treatment of premature ovarian failure in animal models. Based on the available evidence, the study was designed with the aim of investigating the safety and effectiveness of intraovarian injection of MSCs-EV in patients with POF diagnosis.
The purpose of this study is to investigate the brain MRI imaging changes and associated factors on cognition function in patients with premature ovarian failure.
The goal of this pilot study is to improve ovarian reserve markers in patients with premature ovarian insufficiency. The main question it aims to answer is: - Will treatment with G-CSF allow improvement in markers of ovarian reserve?
The aim of this study is to evaluate the evolution of quality of sex life of women with POI after introduction hormone replacement therapy through the FSFI scale
Cervical cancer is one of the most common cancer in women, making it the fourth largest cause of female cancer mortality worldwide. High-risk HPV types (hrHPV) continuous infection is the main cause of the premalignant and malignant lesions of the cervix. The most effective primary prevention of cervical cancer is administration HPV vaccines. There are three prophylactic HPV vaccines including bivalent HPV (2vHPV)， quadrivalent HPV vaccine (4vHPV)，9-valent HPV vaccine (9vHPV) currently. With the widespread of HPV vaccination， the cases related to abnormal menstrual cycle or menstrual irregularities has gradually increased in the Vaccine Adverse Event Reporting System, also the number of reports and studies were increasing. We designed this study to evaluate the statistical association of HPV vaccine and changes in menstrual cycle or menstrual irregularities、amenorrhea. And detect the signal of premature ovarian insufficiency (POI) and related events of three HPV vaccines, and to provide evidence for the safety of HPV vaccines based on the data mining and signal detection method. The research data was obtained from prospective self- developed questionnaire. Before-after study was applied in this study, investigators collect the menstrual cycle data of subjects by the questionnaire and qualitatively interview were taken. The control group is before vaccination, HPV vaccination is Intervention group.
The goal of this clinical trial is to investigate if cryopreservation of ovarian tissue in girls with Turner syndrome can improve their fertility and lead to increased number of liveborn babies of Turner syndrome mothers. Women with Turner syndrome suffer from premature ovarian insufficiency which leads to infertility and lack of estrogen. The main questions it aims to answer are: - Does the number of pregnancies and liveborn children increase after cryopreservation of ovarian tissue in turner syndrome? - Is the possible to predict when a girl with Turner syndrome reach menopause using monitoring of sex hormones? - Is it possible to identify any genes causing ovarian failure in Turner syndrome females? Participants between 2-18 years old will be asked to participate in a laparoscopic surgery and removal of one ovary in order to cryopreserve the tissue until adulthood. The the cortical tissue will be autotransplanted in order to preserve fertility. The participant will during the study period be monitored using sex hormones. Furthermore, the investigators wish to investigate the ovarian tissue using RNA sequencing and DNA methylation analysis. No comparison group is present.
Pelvic chemoradiotherapy (CRT) is an effective treatment for Locally Advanced Cervical Cancer (LACC). However, CRT induces premature ovarian failure ceasing the production of ovarian hormones. This may lead to severe consequences to the patient's life quality, sexuality and overall healthy. An acceptable treatment to minimize the adverse effects caused by the lack of ovarian hormones is hormonal replacement but less than 40% of the patients younger than 50 years have access to this treatment. A second alternative treatment is ovarian transposing which is a surgical technique with variable success rate depending on how far the ovaries are from the radiotherapy field. A third, more promising, alternative is involves using autologous ovarian tissue as a graft in tissues far from the radiotherapy field. This treatment has the potential of maintaining the natural ovarian hormones production at a lower-cost and requiring a simpler procedure. The primary objective of this randomized phase 1-2 clinical trial is to validate the feasibility of ovarian tissue engraft into fatty tissue and its endocrine functionality.
Autologous bone marrow-derived mesenchymal cells will be injected into patients diagnosed with premature ovarian failure
Aim: To evaluate plasma zinc (Zn), copper (Cu), calcium (Ca), iron (Fe), manganese (Mn), selenium (Se), strontium (Sr), aluminum (Al), antimonium (Sb), phosphorus (P), magnesium (Mg), sodium (Na), potassium (K), barium (Ba) and thallium (Tl) levels in women with premature ovarian insufficiency (POI) and to compare the results with those of healthy subjects. Methods: This prospective study will be included 70 women with idiopathic premature ovarian insufficiency and 70 controls. The blood/urine/hair for analyses will be obtained at the early follicular phase of the menstrual cycle and plasma zinc (Zn), copper (Cu), calcium (Ca), iron (Fe), manganese (Mn), selenium (Se), strontium (Sr), aluminum (Al), antimonium (Sb), phosphorus (P), magnesium (Mg), sodium (Na), potassium (K), barium (Ba) and thallium (Tl) levels will be measured using inductively coupled plasma-mass spectrometry.
Aim: To evaluate plasma/urine/hair Lead (Pb), Cadmium (Cd), Gadolinium (Gd), Arsenic (As), Mercury (Hg), Cobalt (Co), Vanadium (V), Titanium (Ti), Sulfur (S), Chromium (Cr), Silver (Ag), Molybdenum (Mo), Boron (B), Lithium (Li), and Nickel (Ni) levels in women with premature ovarian insufficiency (POI) and to compare the results with those of healthy subjects. Methods: This prospective study will be included 50 women with idiopathic premature ovarian insufficiency and 50 controls. The blood/urine/hair for analyses will be obtained at the early follicular phase of the menstrual cycle and plasma Lead (Pb), Cadmium (Cd), Gadolinium (Gd), Arsenic (As), Mercury (Hg), Cobalt (Co), Vanadium (V), Titanium (Ti), Sulfur (S), Chromium (Cr), Silver (Ag), Molybdenum (Mo), Boron (B), Lithium (Li), and Nickel (Ni) levels will be measured using inductively coupled plasma-mass spectrometry.
