Evaluation of day 5 versus day 6 blastocyst biopsy in preimplantation genetic testing: clinical and neonatal outcomes

16 Jun 2025

Abstract excerpt

Background: Preimplantation genetic testing (PGT) has emerged as a pivotal technique in assisted reproductive technology for enhancing success rates by identifying euploid embryos prior to transfer. The optimal timing for blastocyst biopsy during PGT remains controversial, with conflicting evidence regarding the clinical outcomes of day 5 (D5) versus day 6 (D6) biopsies, as well as neonatal and perinatal...
