Impact of Ovarian Factor Mediums on the Apoptotic Gene Expression and Embryo Quality Derived From Vitrified Immature Human Oocytes.

Our findings indicate that the O.F. medium had more potent effects on oocyte growth and cytoplasmic maturation up to the blastocyst stage with the highest expression level of the BCL2 gene and the lowest relative amount of the BAX gene in this medium. The results of the present study have been verified only for parthenogenetically activated embryos, and any positive effect of the environment on the egg/embryo fertilized with sperm requires more extensive studies.
