Abstract
(Abstracted from Nat Cell Biol 2021;23:314–321) Despite it being current practice in vitro fertilization (IVF) protocols to exclude aneuploid embryos diagnosed through preimplantation genetic testing (PGT-A), it remains controversial whether or not this improves IVF outcomes. Both IVF pregnancies and spontaneous pregnancies demonstrate similar levels of mosaicism (12% vs 6.3%).
