1. 01
   IVF cycle

   Eggs are retrieved, fertilized with sperm, and grown to blastocyst stage.
2. 02
   Optional genetic testing

   Embryos can be biopsied for chromosomal screening (PGT-A) or specific gene testing.
3. 03
   Vitrification

   Healthy blastocysts are flash-frozen and stored in liquid nitrogen.
4. 04
   Future transfer

   When ready, embryos are thawed and transferred in a prepared cycle.

Frozen embryo transfers tend to have excellent outcomes because the uterus can be prepared without the hormonal noise of stimulation. Most patients describe transfer day as calm and quick.

Not all embryos survive thaw, though vitrification has dramatically improved survival. Genetic testing has limits — Dr. Ghadir explains exactly what the results can and cannot tell you.
