Previous studies have indicated that the poor-quality embryo transferred with a good-quality embryo does not negatively affect the clinical pregnancy rate or live birth rate. Those 2 cells come together and must do some DNA dividing to make a baby (in the early stages we call that baby an “embryo”). IVF. Fertility researchers found that these embryos often developed into healthy babies regardless of whether they were put onto a blacklist or not. For patients whose embryos have PGT-A, we recommend the transfer of a single chromosomally normal embryo which reduces the chance of multiples (e. Embryo Quality – Choosing Life.
