Overview
Modern vitrification allows embryos to be frozen and later thawed with high survival rates. Cryopreservation supports frozen embryo transfer cycles, planned genetic testing, and long-term fertility preservation.
Common Indications
- Deferring transfer for medical or genetic-testing reasons
- Preserving surplus embryos from an IVF cycle
- Fertility preservation before medical treatment
How It Works
- Embryos are cultured to the appropriate stage.
- Vitrified using rapid-cooling protocols.
- Stored in a controlled cryogenic facility.
- Thawed and transferred in a prepared cycle.
Considerations
- Ask about laboratory survival rates and storage protocols.
- Clarify annual storage fees and disposition options.
