View clinical trials related to Premature Ovarian Failure.
Filter by:Premature ovarian failure (POF) refers the occurrence of amenorrhoea, elevated serum gonadotrophins and hypoestrogenism levels in female before the age of 40. It has important physical and psychological consequences/impact in those patients. Premature ovarian failure (POF) is currently managed by non-physiological sex steroid regimens which are inadequate at optimizing uterine characteristics. Human umbilical cord mesenchymal stem cells (hUCMSCs) and human cord blood mononuclear cells (hCBMNCs) have been shown to have the ability to modulate the immune response and enhance angiogenesis, suggesting the novel and promising therapeutic strategy for POF. In this study, the safety and efficacy of hUCMSCs and hCBMNCs transplantation combined with Hormone Replacement Therapy will be evaluated in patients with Premature Ovarian Failure. Participants will be followed for an expected average of 48 weeks.
Background: - In human DNA, the Fragile X (FMR1) gene helps to regulate the nervous and reproductive systems. If the gene is abnormal, it can cause different kinds of problems, such as abnormal menstrual periods, decreased fertility, muscle tremors, and mental retardation. An abnormal FMR1 gene can also make a person more susceptible to other medical conditions, such as thyroid problems, high blood pressure, seizures, and depression. More research is needed on how abnormalities in the FMR1 gene can lead to these problems, and how often these problems appear in individuals with an abnormal FMR1 gene. - Researchers are interested in developing a patient registry of women who have an abnormality in the FMR1 gene. This registry will allow researchers to follow participants over time and study possible effects of this abnormality on their general and reproductive health. Objectives: - To develop a patient registry of women with an abnormal FMR1 gene and monitor their general and reproductive health. Eligibility: - Women at least 18 years of age who have an abnormal FMR1 gene on the X chromosome. Design: - The following groups of women will be eligible for screening for this study: - Those who have a family member with Fragile X Syndrome or mental retardation - Those who have (or have a family member who has) primary ovarian insufficiency, also known as premature menopause - Those who have (or have a family member who has) certain neurological problems such as tremors or Parkinson's disease. - Eligible participants will be scheduled for an initial study visit at the National Institutes of Health Clinical Center. Participants who have regular menstrual periods should schedule the visit between days 3 and 8 of the menstrual cycle; those who do not have regular periods may have the visit at any time of the month. In addition, all estrogen-based treatments (such as birth control pills) must be stopped for 2 weeks prior to the study visit. - Participants will have a full physical examination, provide a medical history, and provide blood samples for immediate and future testing. Participants will return for yearly visits for the same tests for as long as the study continues. - Participants who have or develop primary ovarian insufficiency related to the FMR1 gene will also have tests to measure bone thickness and will have a vaginal ultrasound to examine the ovaries. These tests will be scheduled for a separate visit, and will be repeated every 5 years for the duration of the study.
DHEA supplementation has been used in women with infertility and diminished ovarian reserve. There is a small report in 5 women with POF that benefited from the use of DHEA over several months. The investigators aim to evaluate further the use of DHEA in women with Premature ovarian failure (POF).
The experimental focus of this project is on the interaction of DHEA treatment on pregnancy in women with open tubes, fertile male partners and evidence of premature ovarian failure.
Estrogen is necessary for feminization during puberty and to decrease bone resorption, the latter critical for the achievement of peak bone mass and normal bone health in the female. The practicing pediatric endocrinologist often faces the dilemma of how to best feminize girls with hypogonadism (lack of estrogen), manifested as delayed or arrested puberty, due to disorders of the brain or the ovaries. We propose a series of studies to address which type, dose, and route of delivery of estrogen are suitable choices in feminizing and sustaining estrogen concentrations in adolescent girls with Turner syndrome. To accomplish this we will study girls/young woman between the ages of 13 to 20 with Turner Syndrome in 2 protocols. In Protocol # 1 we will study 24 girls with TS, they will receive 3 different estrogen preparations, either by mouth or via a patch for a total of 6 weeks. They will come to the clinical research center for blood draws after 2 wks of taking the estrogen. With this study, we hope to learn how the body responds to estrogen differently, depending on the form estrogen is given and how high, estrogen levels gets in the blood in these girls with Turner Syndrome. We will be comparing these patients estrogen levels to girls that menstruate normally and do not have Turner Syndrome. In Protocol #2, 40 patients with TS will be recruited; these patients will take estrogen for 1 year, either by mouth or via a patch. Patients will come to the lab for blood drawn in 7 occasions and we will measure estrogen levels as well as other hormones and lipid levels. We will also perform a Dual-energy X-ray absorptiometry (DXA) study (like an X ray) to assess body composition and bone mineralization. We will adjust doses based on the estrogen levels we find. With this study we hope to learn how estrogen affects body composition, i.e., the amount of fat vs. muscle, and how different forms of estrogen affect blood cholesterol and other hormones. This study will allow us to understand better how to best replace young woman with Turner Syndrome with estrogen.
Premature Ovarian Failure (POF), syndrome observed in young woman, present consequences on hormonal and leads at definitive infertility. It's a rare and complex syndrome and for this reason, we propose to initiate a collaborative team network to understand better his genetic and physiopathology. We are going to realize a global study of this syndrome with clinical and fundamentals approaches. We wish that this project allows us to understand better the physiopathology of this rare disease. Finally, POF responsible genes identification is the base for future development of therapeutics approaches.
The aim of the study is to determine whether physiological sex steroid replacement improves parameters of skeletal, cardiovascular and reproductive health of women treated with current sex steroid replacement regimens.
The aim of the study is to investigate whether inactive FSH plays a role in the development of Premature Ovarian Failure in women with Classic Galactosemia
Primary Objectives: - To determine the effectiveness of the 3-month depot leuprolide in inducing and maintaining secondary amenorrhea in patients undergo hematopoietic stem cell transplantation. - To determine the incidence of regained ovarian function manifested as spontaneous restoration of menstruation and normalization of hormonal level in patients after transplantation and discontinuation of long-acting leuprolide.
The purpose of this study is to evaluate the effectiveness of a modified natural cycle in patients with previous poor response to infertility drugs and high basal FSH, prior to proceeding to oocyte donation or abandoning fertility treatment.
