Filter by:The purpose of this study is to determine whether the administration of an analogue of gonadotropin-releasing hormone (GnRH) during the three months prior to the performing of an IVF may improve the response to ovarian stimulation, implantation rate and clinical pregnancy rate in patients with endometriosis/ endometriomas.
The aim of this study is to assess the oocyte yield of infertile women with suspected or known poor ovarian reserve (POR) undergoing a GnRH antagonist protocol for IVF with Merional® starting either with a low (150 IU) or a high dose (450 IU) and adding 100mg of CC (Serophene®) in the early follicular phase of the stimulation (day 3 to 7). To date no RCT has been conducted to compare the reproductive outcome of patients with POR as defined by the ESHRE Bologna criteria after controlled ovarian hyperstimulation with HMG in an GnRH antagonist protocol using low doses versus high doses of HMG and adding CC versus placebo. We hypothesize that adding 100 mg of CC on day 3-7 to a HMG antagonist protocol will lead to an additional increment of endogenous GT thus increasing the oocytes yield after controlled ovarian stimulation due to higher endogenous gonadotropin secretion.
The objectives of the present trial are to test the following three hypotheses in anovulatory women with PCOS: 1. Acupuncture protocol 1 plus CC (Arm A) is more likely to result in live birth than acupuncture protocol 2 combined with CC (Arm B), 2. Acupuncture protocol 2 plus CC (Arm B) is more likely to result in live birth than acupuncture protocol 1 plus placebo (Arm C), 3. Acupuncture protocol 1 plus placebo (Arm C) is more likely to result in live birth than acupuncture protocol 2 plus placebo (Arm D).
- To test the hypothesis that supplementation of DHEA for at least twelve weeks prior to and during ovarian stimulation increases oocyte quantity (number of oocytes retrieved) and oocyte quality (clinical pregnancy rates and molecular markers) following IVF and IVF/ICSI treatment. - To evaluate the feasibility of conducting a large multicentre trial
Preimplantation Genetic Screening (PGS) is used for the selection of chromosomally normal embryos before the transfer in IVF treatments in many cases. There is great debate in the scientific community as to whether this is an efficient practice in patients of different prognosis. This prospective and randomized study seeks to study the results of chromosomal diagnosis using the new Comparative Genomic hybridization (CGH) arrays technique by practicing Preimplantation Genetic Screening (PGS) in day three biopsy on one arm of the study and not on the other arm in order to compare the results. The investigators will study the ongoing pregnancy rate of each oocyte retrieval and the ongoing implantation rate with Day 5 embryos (blastocysts) in IVF/ intracytoplasmic sperm injection (ICSI) treatments of embryos from two different groups of patients: Advanced Age Female Patients (38 - 41 years of age) and Male severe factor (≥2 million spermatozoids/ml.).
The primary aim of the study is to evaluate if weight management intervention for obese women (BMI≥30<35 kg/m2) prior to IVF improves the outcome assessed as live birth per participating woman, as compared to women where no intervention was made.
The purpose of this study is to assess the non-inferiority of a multidose GnRH antagonist (cetrorelix) regimen to a GnRH agonist (triptorelin) long protocol in young infertile women undergoing ovarian stimulation with Pergoveris 150 I.U./75 I.U. (r-hFSH/ r-hLH) for ICSI treatment because of male infertility. To assess the efficacy of ovarian stimulation using either a GnRH antagonist (cetrorelix) or a GnRH agonist (triptorelin) long protocol in infertile women with good prognosis and to determine the safety of ovarian stimulation. Subsample analysis: in 10 patients of each of both arms, serum samples will be collected daily during the stimulation period and be stored frozen at -70 °C. The following hormone concentrations will be measured later in single assay batches: LH, FSH, oestradiol, progesterone, androstenedione, testosterone, inhibin A, inhibin B, AMH. Multinational, multicentre, open label, randomized, 2-arm parallel-group phase IV study. Eligible patients will be randomly allocated to one of the two groups: the agonist group will receive Decapeptyl® 0.1 mg (triptorelin) starting in the mid-luteal phase of the natural cycle until downregulation until the day of ovulation induction. The antagonist group will receive cetrorelix 0.25 mg from stimulation day 6 to ovulation induction. In both groups, Pergoveris® 150 I.U./75 I.U. (r-hFSH/r-hLH) will be used for ovarian stimulation from cycle day 2 to ovulation induction.
Basing the investigators study on the evidence that basal serum androgens decrease with age, the investigators hypothesize that women with serum androgens below a certain level could be the population obtaining a benefit of Luteinizing Hormone (LH) supplementation. The objective of the present study is to explore the relationship between basal serum androgen levels and the need of LH for Controlled Ovarian Stimulation (COS) in IVF.
Endometrial injury had been studied before prior to intracytoplasmic sperm injection (ICSI) cycles , in cases of repeated implantation failure. It is found that it will improve the implantation rate.
Intralipid infusion can improve outcome in women with recurrent Intracytoplasmic sperm injection ( ICSI) failure due to elevated TH1 cytokine response.
