The microsurgical fragment removal procedure is one of the newest assisted reproduction techniques designed to eliminate cellular fragments that could adversely affect embryo development. A hole is made in the zona pellucidae and most of the fragments are aspirated and eliminated.
What exactly are the cellular fragments?
Human embryos may have celullar fragments in between the blastomeres which fragments of cytoplasm sourrounded by a membrane that have been lost during embryo division. These fragments are originated during the embryo cleavage process and interfere considerably with their further development.
Why is considered microsurgery?
Because it is performed with the microscope under high magnification and it can change embryo’s appearance and return them to their original pregnancy potencial.
