Consider Comprehensive Chromosomal Screening
Comprehensive chromosomal screening (CCS) is a type of preimplantation genetic screening (PGS) that allows embryologists to evaluate ALL 23 pairs of human chromosomes to find out if an embryo has aneuploidy (abnormal numbers of chromosomes).
CCS is thought to help with IVF success by finding the best embryos, with no aneuploidy, to transfer to the woman's uterus. In fact, a new study found that in IVF with single embryo transfer, when embryos were screened with a technique called array comparative genomic hybridization (aCGH) along with studying the morphology, there were improved pregnancy rates over those embryos who were screened by morphology alone. The aCGH group had significantly higher clinical pregnancy rates and a lower miscarriage rate.
