"Our study involved biopsy of the embryo at the blastocyst stage on the 5th or 6th day of development, when the embryo consists of up to 200 cells," said Dr. Scott. "We believe this is much safer for the embryo, and provides much more reliable sampling. Cells are taken only from the portion of the embryo destined to form the placenta, called the trophectoderm. These cells reveal the same genetic information contained within the cells that will eventually form the fetus. By sampling only trophectoderm, we leave the fetal cells untouched and safe from potential compromise."
"We have previously shown our 24 chromosome analysis technology to be significantly more reliable than other existing methods," said Dr. Scott. "However, in the past, it had taken many days to extract this information, requiring us to freeze every embryo for weeks before thaw and use. Our breakthrough has allowed for this same comprehensive screening to be conducted within hours instead of days, eliminating the need for freezing, potential compromise and needless delay. This, indeed, is the first technology of its kind that allows for assessment of blastocysts and still enables a fresh embryo transfer."
Patients seeking In Vitro Fertilization who were less than 43 years old and had no more than one prior failed IVF cycle were invited to participate in the research study. The control group underwent routine care and typical screening methods, whereas the study group underwent biopsy of the blastocyst and Comprehensive Chromosomal Screening on day 5. "Clinical pregnancy rates in the study group were significantly higher, 92%, than those in the control group, 60%," said Dr. Scott. "Also, sustained implantation rates were much higher at 75% in the study group compared to 56% in the control group."
