IVF Procedure: Eggs are retrieved from the ovaries and fertilized with sperm in a laboratory setting. Embryo Development: The fertilized eggs are cultured for about 3-5 days until they reach the blastocyst stage. Biopsy: A few cells are carefully removed from each embryo. Genetic Analysis: The biopsied cells undergo genetic testing to check for specific genetic conditions. Embryo Selection: Only embryos that are free from identified genetic defects are selected for implantation.
