Nowadays, blastocyst biopsy is widely Christmas Tree used in preimplantation genetic tests (PGTs), especially in preimplantation genetic testing for aneuploidy (PGT-A).Compared to polar body biopsy and cleavage stage biopsy, blastocyst biopsy has a higher consistency in the genetic analysis of human embryos and has a less impact on embryo implantation potentials.However, the consistency of genetic tests and the clinical outcome of post blastocyst biopsy can vary depending on biopsy practitioners.This workshop will discuss the handling of blastocyst biopsy Guardian Angel procedure with the purpose of helping participants further advance their blastocyst biopsy techniques.We will review the procedure step by step including post biopsy cryopreservation through formal lectures, salon talks, panel discussions and hands-on training.
We will also discuss trouble shootings from the perspective of an embryology lab and that of a genetic testing lab.
