Filter by:Rationale: Due to accelerated germ cell loss, infertility is a major problem in girls with Turner syndrome (TS). Therefore, cryopreservation of ovarian tissue or oocytes before exhaustion of the ovarian reserve may preserve fertility in patients with TS. However, in the majority of females with TS , the ovarian reserve is exhausted before the age of menarche. Early markers indicating and predicting the ovarian reserve are necessary. During mid-childhood the hypothalamic-pituitary-gonadal (HPG) axis is quiescent and gonadotropins are usually unmeasurable. Nonetheless, this axis is active during infancy. Therefore, gonadotropins are measurable with peak values at 3 months of age and with lower (but still measurable) values at 9 months of age, in a period called the minipuberty. The aim of this study is to find markers of ovarian capacity, during the minipuberty, in order to predict ovarian reserve in the future. Objective: The hormonal range of LH, FSH, AMH, inhibin B, testosterone and estradiol in girls with TS during the minipuberty and the relation of the hormone serum levels with the karyotype. Study design: A prospective, cohort study with a duration of 3 years. Study population: Girls with a pre- or perinatal diagnosis TS who are born in a medical centre in the Netherlands during the duration of the study Main study parameters/endpoints: Serum levels of FSH, LH, AMH, inhibin B, testosterone and estradiol at the age of 3 and 9 months.
Autologous PRP intra ovarian infusion may restore ovarian function, may promote folliculogenesis and may improve patients' hormonal profile in patients presenting with POI.
A randomized prospective study in the evaluation of the long acting GnRH antagonist Degarelix against the classical multidose regime with Ganirelix for LH suppression during the follicular phase of an ovarian stimulation cycle in oocyte donors.
Reduced ovarian reserve and the consequent poor ovarian response are very recurent in infertile patients, indeed a percentage of 10%-24% of couples addressed to infertility program may be classified as Poor Ovarian Responder (POR). Objective: To evaluate whether the repeated luteal phase stimulation (Second Step) permits a significantly higher number of oocytes retrieved in POR when compared to conventional follicular stimulation. Interventions: The follicular phase stimulation is conduced according to a standardized Antagonist protocol or Short protocol (with GnRH agonist) using recombinant or urinary gonadotropins (starting dose 300 or 450 UI) or a long lasting recombinant gonadotropin (Corifollitropin alfa 150 mcg). Two - six days after the first oocyte retrieval a second gonadotropin stimulation will be started with a GnRH antagonist protocol (the stimulation will be started with 250 UI of human menopausal gonadotropin (hMG) and a GnRH antagonist (GnRH-an) 0,25 mg\die will be administered when the leading follicle is ≥ 14 mm until hCG (human chorionic gonadotropin) criteria are met. When at least two follicles had reached 17-18 mm in diameter, ovulation will be triggered with a single subcutaneous bolus of urinary human chorionic gonadotropin (10.000 UI ) and oocyte retrieval will be performed after 35 hours. Two or Three months after the second oocyte retrieval the Embryo transfer (ET) will be performed after endometrial preparation with Estradiol Valerate and intramuscular Progesterone.
genetic screening and etiological analysis was conducted on patients with ovarian insufficiency and decline in ovarian reserve. All patients were enrolled in the IVF-treated and non-IVF-treated groups, followed up for long-term treatment outcomes and genomic screening.
The goal of this study is to determine safety and tolerability and of intra-ovarian injection of adipose derived stromal cell in women with premature ovarian failure and to study the preliminary efficacy ADSCs intra ovarian injection on ovarian function improvement.
Stem cells (SC) are the foundation cells for every organ, tissue and cell in the body. They are undifferentiated "blank" cells that do not yet have a specific function. Under proper conditions, they begin to develop into specialized tissue and organs. They are self-sustaining and can replicate themselves for long periods of time. They have the remarkable potential to develop into many different cell types in the body. They serves as a sort of repair system for the body, they can theoretically divide without limit to replenish other cells as long as the person is still alive. Premature ovarian failure (POF) is the loss of ovarian function in women less than 40 years. It is associated with sex steroid deficiency, amenorrhea, infertility and elevated serum gonadotropins. POF occurs in 1 % of women. In majority of cases the underlying cause is not identified. Management essentially involves hormone replacement and infertility treatment. This work aimed to evaluate the therapeutic potential of Autologous MSC transplantation in women suffering from Premature Ovarian Failure.
Premature ovarian failure (POF), also known as premature ovarian insufficiency, primary ovarian insufficiency (this is the most accurate term as some women may still conceive), premature menopause, hypergonadotropic hypogonadism is defined as failure of the ovary to function adequately in a woman younger than 40 years, in its role either as an endocrine organ or as a reproductive organ, a condition characterized by amenorrhea, hypoestrogenism, and elevated serum gonadotropin levels (which demonstrate that the ovaries are no longer responding to circulating FSH by producing estrogen and developing fertile eggs) in women younger than 40 years. This condition occurs in approximately 1% of women and it has important physical and psychological consequences/impact in those patients. The purpose of this study is to investigate the role of the transplantation of bone marrow derived stem cells into ovarian tissue for treatment of premature ovarian failure and to assess their ability to differentiate into germ cells.
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.
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.
