The practice continues to maintain some of the highest IVF success rates when compared to the national average and is dedicated to maintaining an embryology lab which offers cutting-edge technology such as intracytoplasmic sperm injection (ICSI), laser assisted zona hatching, embryo biopsy for pre-implantation genetic diagnosis, and cryopreservation.
Alternatively, the poor results of PDG and PGS on day three embryos lead to performing the embryo biopsy on blastocyst on day five after fertilization.

Because we can grow embryos in the lab we now have the ability to remove a single cell from an embryo, basically we do an embryo biopsy and analyze the DNA of that cell.
This new ability to do a day-5 embryo biopsy and get the results back so fast that there's no need to undertake a frozen embryo transfer is a significant advance, Dr.
Considering the beneficial effect of temporary period of culture between embryo biopsy and cryopreservation on post warming survival rate of embryos and considering the cryotolerance of In Vitro Produced (IVP) embryos as a criteria to evaluate the quality of IVP embryos, this study was conducted to evaluate the effect of age and cell number of embryos at the time of biopsy on the quality of biopsy derived blastocysts.
