The true incidence of chromosomal mosaicism after preimplantation genetic testing is much lower than that indicated by trophectoderm biopsy

3 Mar 2021

Abstract excerpt

STUDY QUESTION: What is the true incidence of chromosomal mosaicism in embryos analyzed by preimplantation genetic testing (PGT). SUMMARY ANSWER: The true incidence of chromosomal mosaicism is much lower than we usually surmise. WHAT IS KNOWN ALREADY: In recent years, contemporary methods for chromosome analysis, along with the biopsy of more than one cell, have given rise to an increased rate of chromosomal...
