Embryo Freezing
A safe, effective option for preserving your fertility or storing extra embryos after IVF.
Embryo freezing is a fertility preservation technique that allows embryos to be safely stored for future use. It is commonly used by individuals and couples undergoing in vitro fertilization (IVF) who wish to delay pregnancy, preserve extra embryos, or safeguard fertility before medical treatments like chemotherapy. By freezing embryos at an early stage of development, patients maintain the opportunity to attempt pregnancy later without undergoing another full IVF cycle.
This method uses a rapid freezing process called vitrification, which protects the cells from damage during storage. Frozen embryos can remain viable for many years and offer similar success rates to fresh embryo transfers when thawed. Whether you’re preserving embryos for personal, medical, or family-building reasons, embryo freezing provides long-term flexibility and reassurance.
How It Works: Step-by-Step
1. Ovarian Stimulation. You take hormone injections for 8–12 days to stimulate the development of multiple eggs in your ovaries.
2. Egg Retrieval. Mature eggs are collected through a short outpatient procedure under light sedation, typically guided by ultrasound.
3. Fertilization. The retrieved eggs are fertilized in the lab using sperm from a partner or donor. This is done via traditional IVF or ICSI (a single sperm injected into each egg).
4. Embryo Culture. Fertilized eggs develop into embryos over 3–7 days. Embryologists assess them daily for growth and quality.
5. Freezing (Vitrification). High-quality embryos are frozen quickly using vitrification, a rapid freezing technique that prevents ice formation and protects embryo structure.
6. Secure Storage. The frozen embryos are stored in liquid nitrogen tanks and remain viable for many years, ready for future frozen embryo transfers (FET) when you’re ready.

FAQs
Frequently Asked Questions
How long can embryos be frozen and still be viable?
What is the success rate of frozen embryo transfers (FET)?
Does freezing embryos damage them?
The vitrification process used today minimizes ice crystal formation, which protects the embryo. Most embryos survive the thawing process with a high success rate.
Who should consider embryo freezing?
Is embryo freezing different from egg freezing?
Yes. Egg freezing involves freezing unfertilized eggs, while embryo freezing is done after fertilization when the sperm and egg are combined. Embryos tend to have higher survival rates after thawing compared to eggs.
