The human oocyte is surrounded by the zona pellucida—an elastic, transparent extracellular matrix consisting of specific glycoproteins. The zona pellucida is preserved after fertilization and surrounds the developing human embryo for a few days. The embryo needs to get out of the zona pellucida before implantation to establish cell contacts between the

To date preimplantation diagnosis has been made in the two-eight cells embryos because these are available in IVF programs. However, most patients referred for IVF are infertile, very few undergoing IVF with the thought of preimplantation diagnosis.

Cryopreservation of Blastocysts
2001Based on observations collected from IVM-IVF bovine blastocysts, we developed and modified cryopreservation programs for human co-cultured blastocysts. We have used glycerol as cryoprotectant, and sucrose. We were surprised to observe that the in vitro grown blastocysts are rather more sensitive to high concentrations of cryoprotectants.
