CCS at CCRM Northern Virginia
In 2007, CCRM changed the in vitro fertilization (IVF) landscape by developing a technique that involves testing embryos at the blastocyst stage to determine whether an embryo has a normal or abnormal number of chromosomes. Comprehensive chromosomal screening (CCS) is done by safe the removal of several embryonic cells. Then, genetic testing is performed to screen the embryos for the correct number of chromosomes (23 pairs).
The rationale is that as a woman ages, there is an increased risk for chromosomal abnormalities. An estimated 70% of early miscarriages are associated with a chromosomal abnormality in the fetus. The goal of CCS is to avoid transferring abnormal or “aneuploid” embryos which would either fail to implant, result in miscarriage, or lead to a fetal aneuploidy such as Down Syndrome.
This technique has been successfully adopted by fertility clinics across the globe resulting in the birth of tens of thousands of healthy babies. CCRM Northern Virginia is happy to offer CCS in conjunction with IVF to our patients.
Who are candidates for CCS?
Women over the age of 35 years.
Patients with recurrent pregnancy loss.
Patients with recurrent implantation failure.
Patients with prior unsuccessful fertility treatments.
Patients who require single embryo transfer for medical reasons, or who strongly desire single embryo transfer.
What are the advantages of CCS?
Increased probability of live-birth with elective single embryo transfer.
Reduced rates of multiple pregnancy.
Lower pregnancy loss rates.
Reduction in unsuccessful embryo transfers and thus fewer fertility treatment procedures per live birth.
Shorter time interval from treatment start to ongoing pregnancy and live birth.
Enhanced information about the potential for pregnancy in cryopreserved embryos.
