Patients undergoing in vitro fertilization (IVF) have the option to have the embryo assessed through Comprehensive Chromosome Screening (CCS). The primary purpose of CCS is to transfer embryos that possess the appropriate number of chromosomes after thorough analysis and selection.
Due to tremendous improvements in CCS, genetic screening of embryos can help those patients who had undergone multiple IVF cycles, patients who have a history of miscarriage, and women 35 years of age or older whose eggs are at a higher risk of chromosome errors. CSS helps patients achieve higher implantation rates and less pregnancy terminations.
When the embryo created by the IVF process reaches the blastocyst stage (day 5-6), the doctor removes a few cells from the embryo. The chromosomes present in an embryo’s cell are then counted.

Normally, each cell contains 23 pairs of chromosomes. Aneuploidy is the condition in which there is a presence of abnormality in the number of chromosomes. Studies show that aneuploidy causes over 60 percent of miscarriages and reduces the success rate of IVF. The risk of producing an embryo with aneuploidy increases as a woman ages. Thus, the risk of miscarriage also increases as a woman ages. Implanting embryos with the correct number of chromosomes then improves the success rate of pregnancy and IVF.
Patients who will be freezing all of their embryos and those who wish to have only one transplant can also benefit from CCS. This preimplantation genetic screening can truly make a positive impact on IVF.
