This procedure includes testing embryos produced via IVF, selecting and transferring the ones with the correct amount of chromosomal material.
• A biopsy of the embryo is taken after it is grown in culture for about five days and reaches the blastocyst developmental stage made up of hundreds of cells.
• The biopsy involves the removal of 5 to 7 cells of the external layer of the embryo, called trophectoderm, without touching the inner cell mass that gives rise to the fetus.
• Analysis of the embryo’s genetic material is carried out.
• Embryos are cryopreserved following biopsy. The suitable embryos, based on the PGT-M results, are thawed and transferred to the patient's uterus in a subsequent cycle.
