Brief Summary:

Infertility affects an increasing number of couples. For many, the choice of treatment is in vitro fertilization (IVF) . Currently, there are no markers fully predictive of developmental competence of IVF embryos. Present embryo selection is based on morphology assessment, which produces implantation rates in the range of 20%-30 %. The overall purpose of the present study is to investigate methods for selection of the best embryo. We aim to examine the relationship between pregnancy outcome and the transcriptional profile of selected genes, cleavage kinetics (time-lapse), and metabolic profile. We hypothesise that the quality of the embryo is reflected by the transcription of selected genes, the cleavage kinetics, and the metabolic profile. If so, these parameters can predict the success or failure of a pregnancy. Furthermore, the interrelationship - if any - between these parameters will be evaluated.

A secondary aim is to evaluate the effect of blastomere biopsy using time-lapse and metabolic analysis

Primary Outcome Measures :
  1. implantation/clinical pregnancy confirmed with pregnancy test and ultrasound [ Time Frame: 8 weeks after embryo transfer ]
    measurement of urine-hCG and vaginal ultrasound scan to evaluate pregnant/not pregnant

Secondary Outcome Measures :
  1. gene expression quantified with Q-PCR [ Time Frame: within 6 months after biopsy and embryo transfer ]
    RT-Q-PCR analysis of selected genes

  2. Metabolic profile using NIR analysis [ Time Frame: within 6 months after collection ]
    Near Infrared Spectroscopy (NIR) of the spent culture media. The spectral profile is used to calculate a viability index

  3. cleavage kinetics [ Time Frame: before embryo transfer, during culturing ]
    imaging of the developing embryos during culturing. Data analysis concerning morphological parametres within 6 months after embryo transfer

Biospecimen Retention:   Samples With DNA
biopsies from human embryos
