Evaluation of Donated Human Embryos for Study of Normal and Abnormal Differentiation and Development Following in Vitro Fertilization.

Undergoing IVF treatment often results in the production of more embryos than can safely be transferred at one time. These extra embryos are often cryopreserved for future use. In the event that a couple decides that they do not want to proceed with using cryopreserved embryos, these embryos can be discarded, donated to another couple, or donated to research.

Embryos that are donated to research are used to identify a group of parameters that have significant predictive value for assisted reproductive technology outcomes. We hope to develop future laboratory techniques as we gain a better knowledge of gamete development, fertilization and implantation. We will test, standardize and implement better methods for freezing embryos prior to employing these techniques in a clinical setting. We hope to develop new methods to optimize the determination of genes and chromosomes in embryos. We will test the proficiency of laboratory staff on techniques and/or procedures done in the IVF laboratory. This study WILL NOT:create embryos for research, transfer embryos to an individual, develop cell lines or clones.
