Preimplantation Embryo Genetic Screening (PGS) CapitalBio

Chromosome abnormality exists in around one-third of the embryos created through assisted reproductive technologies (such as IVF) and is a primary cause of pregnancy failure and miscarriage. Pre-implantation Genetic Screening (PGS) refers to the selection of one or more cells for chromosome number and structure abnormality testing during assisted reproductive technology and prior to embryo implantation in order to achieve a normal pregnancy, improve the patient’s clinical pregnancy rate, and reduce the risk of early miscarriage. According to study, PGS can greatly boost IVF indices.
