1. Ovarian Stimulation and Egg Retrieval: The woman undergoes ovarian stimulation to produce multiple eggs, which are then retrieved.
2. Fertilization: The retrieved eggs are fertilized with sperm in the lab to create embryos.
3. Embryo Biopsy: On day 5 or 6 of embryo development, a few cells are carefully removed from the embryo. This process does not harm the embryo's development.
4. Genetic Analysis: The biopsied cells are analyzed in a genetic lab to screen for specific genetic abnormalities or chromosomal irregularities.
5. Embryo Transfer: Healthy embryos without genetic abnormalities are selected and transferred to the uterus for implantation.
