What Is Embryo Freezing?
Embryo freezing, also known as embryo cryopreservation, is the process of creating embryos through IVF (in vitro fertilisation) and freezing them for future use. The process involves stimulating the ovaries to produce eggs, retrieving those eggs, fertilising them with sperm in a laboratory, and then freezing the resulting embryos using advanced preservation techniques.
This differs from egg freezing, where unfertilised eggs are frozen. With embryo freezing, fertilisation happens before storage, meaning the embryo is already formed and preserved in its earliest stage of development.
Patients may choose embryo freezing for a range of reasons, including fertility preservation due to medical treatment, personal circumstances, or as part of IVF treatment planning. For many, it provides a greater sense of certainty because embryo development and fertilisation success have already occurred prior to freezing.
The Embryo Freeze Cycle Explained
The embryo freeze cycle follows a carefully managed and clinically monitored process designed to prioritise safety, comfort, and success.
It begins with ovarian stimulation, where hormone medications encourage the ovaries to produce multiple mature eggs. This stage is closely monitored through blood tests and ultrasounds to ensure optimal timing and response.
Once the eggs are ready, an egg retrieval procedure is performed. This is a minimally invasive, day procedure conducted under light sedation, where eggs are collected directly from the ovaries.
The retrieved eggs are then fertilised in Fertility SA’s laboratory using either conventional IVF or ICSI (intracytoplasmic sperm injection), depending on individual clinical needs. The fertilised eggs develop into embryos over several days, with embryologists carefully monitoring their development and quality.
At the appropriate stage, suitable embryos are selected for freezing. Patients can feel reassured that this process is supported by advanced laboratory technology, strict safety protocols, and highly trained fertility scientists.
Freezing and Storage Process
Embryos are frozen using a method called vitrification. This is a rapid freezing technique that prevents ice crystal formation, protecting the embryo’s structure and cellular integrity.
Once vitrified, embryos are securely stored in specialised cryogenic storage tanks at extremely low temperatures. These systems are designed for long-term preservation, with strict monitoring, identification protocols, and security procedures in place.
Modern vitrification and storage methods have made long-term embryo freezing safe, stable, and highly effective. Embryos can remain preserved for many years without deterioration in quality, allowing patients to return to treatment when the timing is right for them.
Who Should Consider Embryo Freezing
Embryo freezing can be suitable for a wide range of patients, depending on their personal, medical, and reproductive circumstances. Common reasons people choose embryo freezing include:
Fertility preservation before medical treatments such as chemotherapy, radiotherapy, or surgery that may affect fertility
IVF patients who create multiple embryos and wish to preserve them for future pregnancy attempts
Couples or individuals wanting to delay pregnancy for personal, career, or life-planning reasons
People with known fertility conditions such as endometriosis, PCOS, or reduced ovarian reserve
Patients seeking a more predictable fertility preservation option compared to egg freezing
At Fertility SA, every patient receives personalised medical guidance to determine whether embryo freezing aligns with their health, fertility goals, and future family plans.

Embryo Freezing Success Rates
Embryo freezing success rates in Australia are consistently strong, supported by advances in IVF technology, vitrification techniques, and laboratory science. Pregnancy outcomes using frozen embryos are now comparable — and in some cases equivalent — to those using fresh embryos.
Success is influenced by several factors, including the age of the patient at the time of egg retrieval, embryo quality, underlying fertility conditions, and overall reproductive health.
Fertility SA’s outcomes reflect a strong clinical track record supported by expert specialists, experienced embryologists, and advanced reproductive technology. Patients benefit from evidence-based care, rigorous quality standards, and personalised treatment planning that prioritises both safety and success.
Embryo Freezing Cost
The cost of embryo freezing in Australia can vary depending on individual treatment plans, medication requirements, laboratory processes, and storage duration.
An embryo freeze cycle typically includes:
Medical consultations and fertility assessments
Ovarian stimulation monitoring
Egg retrieval procedure
Fertilisation and embryo development
Freezing (vitrification)
Initial storage period
Some aspects of treatment may be eligible for Medicare rebates, depending on medical criteria and treatment structure. Fertility SA provides transparent cost information and clear guidance on what is included in each stage of care.
Because every fertility journey is different, the most accurate pricing is provided through a personalised consultation, where your specialist can outline treatment options, expected costs, and available rebates.

Embryo Freezing vs Egg Freezing
While both embryo freezing and egg freezing are fertility preservation options, they differ in process and suitability.
Egg freezing involves freezing unfertilised eggs, offering flexibility for individuals who do not yet have a partner or sperm source. Embryo freezing involves fertilisation before freezing, creating embryos that are ready for future transfer.
Embryo freezing may provide greater predictability in outcomes because fertilisation and early development have already occurred. Egg freezing offers autonomy and independence in family planning.
The right option depends on personal circumstances, fertility health, relationship status, and future goals. Fertility SA supports patients in understanding these differences and choosing the option that best aligns with their life plans and medical needs.

FAQs
How many embryos should I freeze?
This depends on age, fertility health, embryo quality, and future family goals. Your specialist will guide you based on your individual circumstances.
How much to freeze embryos in Australia?
Costs vary depending on treatment plans, medications, and storage duration. A personalised consultation provides the most accurate pricing information.
How long can you freeze an embryo?
Embryos can be safely stored for many years using modern vitrification and cryogenic storage systems.
Are embryos fertilized before freezing?
Yes. Embryos are created through IVF or ICSI before being frozen and stored.
How is embryo freezing different from egg freezing?
Embryo freezing involves fertilising eggs before freezing, while egg freezing preserves unfertilised eggs. Embryo freezing offers more certainty around fertilisation and early development.
