View clinical trials related to Premature Ovarian Failure.
Filter by:Reproductive age women diagnosed with poor ovarian response (POR) based on Poseidon criteria and premature ovarian insufficiency (POI) based on ESHRE criteria and with a history of at least one prior failed IVF cycle will be recruited for the study. Antral follicle count (AFC), serum anti-mullerian hormone (AMH), and early follicular phase serum follicle stimulating hormone (FSH) levels will determined at baseline. Autologous blood obtained from peripheral vein will be used to prepare PRP following standard protocols and will be injected to at least one ovary. Ovarian reserve parameters and IVF outcomes will be determined.
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.
All encountered cases with POI will be assessed and examined then investigated. Eligible cases will be included in the study
The study will describe the effectiveness of ovarian stimulation in correlation with female infertility causes in a Lebanese population: a comparative study using 5 protocols of ovulation induction (treatment with "A" gonadotropins alone, "B" short GnRH agonist, "C" multiple-dose GnRH antagonist, "D" long GnRH agonist and "E" combined protocol of GnRH antagonist and agonist) and the outcomes of ICSI. This comparative study will help clinicians to select the relevant protocol of ovarian stimulation related to the female infertility disorders.
Autologous PRP intra ovarian infusion may restore ovarian function, may promote folliculogenesis and may improve patients' hormonal profile in patients presenting with POI.
SEGOVA procedure includes - Stem cell therapy, G - Growth factor Platelet Plasma Rich therapy and in Vitro Activation of the ovaries.
The aim of this study is the safety and efficacy of autologous very small embryonic-like stem cells(VSELs) to premature ovarian failure.
Objective: To evaluate serum endocan levels in women with premature ovarian insufficiency (POI) and to compare the results with those of healthy subjects. Methods: This prospective study included 38 women with idiopathic POI and 39 controls. The blood for analysis was obtained at the early follicular phase of the menstrual cycle and serum endocan levels were measured using a commercially available ELISA kit. Follicle-stimulating hormone (FSH), estradiol, and anti-mullerian hormone (AMH) were measured at the same time. The continuous values were evaluated using Student's t-test, and categorical values were evaluated using the Chi-square test. P values < .05 were accepted as significant.
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.
The current study will compare hormone levels of AMH, FSH and inhibin B in blood specimens collected by venipuncture and fingerstick in a sample of pre-menopausal women ages 18-45 years with normal menstrual cycles.
