Detailed Description
Chromosomal abnormalities commonly exist in early human embryos, and often cause embryo implantation failure and pregnancy loss in in-vitro fertilization (IVF) treatments. Preimplantation genetic testing for aneuploidies (PGT-A) by comprehensive chromosome screening (CCS) has been widely applied in IVF practices to select embryos with normal ploidy. Although multiple clinical trials have demonstrated improved clinical outcomes with PGT-A, it's in controversial for whether PGT-A is truly worthwhile to be offered to all IVF patients. One of the main concerns is that it involves an embryo biopsy procedure, which is invasive and the long-term safety issue of the embryo biopsy remains to be fully investigated.
In recent years, researchers have found that the spent medium of embryo culture contains trace amount of cell-free DNA, which may reflect the ploidy of the embryo. The non-invasive chromosome screening (NICS) approach utilizing spent culture medium samples has been evaluated in studies. However, the clinical value of NICS as a new effective indicator to evaluate embryo competence so far has not been justified by randomized clinical trials.
The main purpose of this project is to verify whether NICS can be used as a new effective indicator for evaluating embryo developmental potential through multi-center, randomized clinical trials
