DOES TROPHECTODERM BIOPSY FOR PREIMPLANTATION GENETIC TESTING AFFECT FETAL BIRTH WEIGHT OR RATE OF PRETERM DELIVERY? A SART CORS STUDY

Abstract

Preimplantation genetic testing for aneuploidy (PGT-A) is used as part of IVF treatment to select euploid embryos, and involves trophectoderm biopsy of blastocysts. The effects of possible trauma caused by biopsy of the blastocyst and implications on placental development are unknown. Therefore, the goal of our study was to evaluate if PGT-A is associated with adverse neonatal birth outcomes, including birthweight, small for gestational age (SGA), and preterm birth (PTB).
