Active clinical trials for "Infertility"

The purpose of the study is to determine whether administration of dietary supplement of astaxanthin with vitamin E improves the quality of sperm, fertilization and embryo development in Assisted Reproduction Techniques (ART) procedures.

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.

In combination with the existing literature, previous work indicates that 1) women with poor ovarian response fulfilling the "Bologna criteria" have very low pregnancy rates, irrespective of age 2) current treatment protocols demonstrate ongoing pregnancy rates that do not exceed 8.5% and 3) corifollitropin alfa followed by hpHMG might increase ongoing pregnancy rates in young patients (<40years old) fulfilling the criteria. These findings provide a strong rationale for a definitive large RCT. The COMPORT study will provide conclusive evidence regarding the superiority or not of this novel protocol with corifollitropin alfa followed by hpHMG for the treatment of young poor ovarian responders fulfilling the Bologna criteria.

This trial investigates the immunogenicity of FE 999049 in repeated cycles.

Implantation failure remains one of the major factors limiting success in IVF treatment. It was postulated that the local injury to endometrium induces secretions of cytokines and growth factors such as leukemia inhibitory factor, interleukin-11, and heparin-binding EGF-like growth factor which enhance decidualisation and facilitate implantation. It may also up-regulate the gene expressions related to endometrial receptivity and optimize the endometrial development. In stimulated cycles, local injury to the proliferative endometrium has been postulated to delay endometrial development thereby inducing synchronicity between endometrium and embryo stage and facilitate implantation (Zhou et al, 2008; Almog et al, 2010; Gnainsky et al, 2010) The aim of the study is to determine whether endometrial injury by endometrial biopsy in mid-secretory phase of the preceding cycle would improve the on-going pregnancy rate in subfertile women undergoing IVF treatment.

There are different controlled ovarian hyperstimulation protocols utilized in infertility patients. In this study, our aim is to specifically compare three protocols in poor responding infertility patients.

To salvage the luteal phase and improve pregnancy rate in antagonist IVF/ICSI cycles triggered with GnRH agonist. Two strategies are compared supplementing the luteal phase with three small doses (500 IU) of HCG and giving a booster dose of HCG (1500 IU) on the day of ovum pickup.

The aim of this project is to activate recruitment and growth of resting primordial follicles in the ovaries of women with diminished ovarian reserve, in attempt to increase the chance to become pregnant, either naturally or after assisted reproduction.

The principle objective is to improve embryo quality through autologous micro-injection of mitochondria isolated from Ovarian stem cells into the oocytes themselves, as a complementary ICSI technique in patients with low embryo quality in previous IVF cycles and in those who did not bear children. This improvement in embryo quality will be determined through on-going pregnancy rate after treatment and/or improvement in embryo quality according to morphological (ASEBIR-"Association for the study of Biology in Reproductive Science), morphokinetic criteria and in Preimplantation Genetic Screening. Using an adaptive design, retrieved oocytes of approximately 60 patients will be randomized in the first part of the study to two treatment groups; standard ICSI procedure without mitochondrial supplementation and ICSI with autologous mitochondrial supplementation. Following an interim analysis of outcomes, an additional 130 patients may be added, for a total of 190 patients.
