Preserving Your Future with Confidence
Embryo freezing (embryo cryopreservation) allows you to preserve healthy, viable embryos for future use. Whether you have surplus embryos after a successful IVF cycle, are not yet ready to start a family, or want to safeguard your fertility before medical treatment, embryo freezing offers a reliable and scientifically proven solution.
How Embryo Freezing Works
After fertilisation and embryo development, any embryos not used in the fresh transfer cycle are assessed for quality. Those meeting the required standard are frozen using a rapid-freeze technique called vitrification, which prevents ice crystal formation and preserves cellular integrity. Embryos are stored in liquid nitrogen at -196°C and can remain viable for many years.
Key Benefits of Embryo Freezing
- Preserves additional embryos from a single stimulation cycle
- Vitrification survival rates of over 95%
- Reduces the need for repeated ovarian stimulation
- Offers flexibility to plan your family on your own timeline
- Suitable for fertility preservation before chemotherapy or surgery
Who Is a Good Candidate for Embryo Freezing?
- Patients with surplus embryos after IVF
- Women or couples not yet ready for pregnancy
- Those undergoing cancer treatment or other medical procedures
- Women wishing to preserve fertility at a younger age
- Couples planning staged transfers for medical or personal reasons
Embryo Freezing Timeline
Day 1-12
Ovarian stimulation and egg retrieval as part of a standard IVF cycle.
Day 1-5
Eggs fertilised via ICSI. Embryo development monitored in the lab.
Day 5-6
Quality embryos assessed. Those not transferred are vitrified and stored.
Storage
Embryos stored safely in liquid nitrogen at -196°C. Annual storage fees apply.
When Ready
Frozen embryo transfer (FET) cycle begins with endometrial preparation.
2 Weeks Post-Transfer
Pregnancy test. Remaining embryos stay frozen for future attempts.
Frequently Asked Questions About Embryo Freezing
Embryos can be stored for many years — in some countries up to 10 years or longer. Clinical evidence shows no deterioration in viability with extended storage when vitrification is used.
With modern vitrification techniques, more than 95% of frozen embryos survive the thaw process. Pregnancy rates from frozen transfers are comparable — and sometimes better — than fresh transfers.
Yes. Your frozen embryos can be transported to a partner clinic in another country if needed. We assist with all logistics including specialised medical transport and legal requirements.
