Filter by:Recently, it has been suggested that culture of embryos in EmbryoGen medium can increase the live birth rate in IVF patients with a previous history of pregnancy loss. Couples requiring IVF treatment and with a past experience of miscarriage and/or biochemical pregnancy will be included in the study. Controlled ovarian stimulation protocol will consist of an agonist down regulation and follicular stimulation by recombinant FSH. Fertilization will be achieved by standard IVF or intracytoplasmic sperm injection. Fertilized eggs will be cultured in 6% CO2, 5% O2, 89% N2 atmosphere in microdrops. In the treatment group EmbryoGen culture medium (EG, Origio, Måløv, Denmark) will be adopted throughout the culture period. In the control group, inseminated oocytes will be cultured in standard culture conditions, i.e. IMS1 medium (ISM1, Origio, Måløv, Denmark), maintaining unchanged all other culture conditions. Procedures of embryo transfer, will be carried out on day 2 using EmbryoGen or ISM1 respectively. The endometrial support will be the same in the two groups. The investigators will consider ongoing clinical pregnancy as the primary outcome assuming a 25% of increment in ongoing clinical pregnancy rate in the group with EmbryoGen medium. As secondary outcome the investigators will assume a 5% of increment in ongoing implantation rate after 12 weeks in the group with EmbryoGen medium.
The purpose of this this study is to use DNA screening strategies to identify genes and localize genomic regions that are differentially expressed in patients with infertility to further understand the genetic basis for reproductive competence.
This is a research study in which your cells will be used for somatic cell nuclear transfer (SCNT), and/or genetic reprogramming research which may result in the production of stem cell lines. This study does not provide treatment.
