If you have hopes of having children but aren't quite ready for parenthood — have you thought about putting your eggs on ice?
When it comes to female fertility, timing is the most important factor and being proactive can make a big difference in your chances of becoming a parent. Today, science has given you the option to say ‘yes' to parenthood when you’re ready.
What is egg freezing?
Egg freezing is a method of storing unfertilised eggs to allow you to try to conceive at a later date, when natural conception would be unlikely. It's often seen as a way of preserving the possibility of fertility for those who are not currently in a position to become pregnant, or whose fertility is at risk for medical reasons such as cancer treatment.
Frozen eggs may be stored for many years without significant deterioration. When someone is ready to use the frozen eggs, they are warmed and then fertilised with sperm. The aim is for the fertilised egg to develop into an embryo, which can then be transferred to the uterus giving a chance of pregnancy.
What is the egg freezing process at TasIVF?
View the step-by-step process below.
Step 1: Hormonal Stimulation
The egg freezing process begins with hormonal stimulation for about 10 – 12 days. The medications are self-administered by a daily injection using a simple pen device with a small needle.
Our specialists will hold a personalised instructive introductory consultation with you to teach you how to do this. Please note that the injections may make you feel a little bloated but there are no frequent significant side effects, allowing you to carry out all your normal activities throughout the period of stimulation.
Step 2: Egg Collection
Once the egg freezing specialist confirms there are enough eggs (with monitoring via blood tests and ultrasound), the egg collection procedure will be scheduled. This process is usually carried out under light general anaesthetic or with sedation.
You can go home 1-2 hours after and are advised not to drive and to rest for the remainder of the day. This procedure is performed by fertility specialist using an ultrasound-guided probe. Attached to the ultrasound probe is a needle guide. The fine needle passes through the vaginal wall into the ovary and draws the fluid (and your precious eggs) from the ovary.
Step 3: Freezing the eggs
Once in the laboratory, your eggs undergo a freezing procedure called vitrification. This involves rapidly freezing the eggs using a process that extracts fluid from the eggs to prevent potentially damaging ice crystal formation. Once vitrified, your eggs can stay preserved for years to come.
Cost of freezing eggs
Egg freezing costs can vary depending on individual circumstances and the types of services required. A major factor contributing to the cost of egg freezing is whether the patient is receiving an elective egg freezing treatment or seeking medical fertility preservation.
At TASIVF, we offer priority access to those undergoing cancer treatment. This includes a bulk billed consultation with a fertility specialist and minimised storage fees.

Is egg freezing covered by Medicare?
It's important to note, Medicare rebates only apply to medical fertility preservation.
During your initial consultation, your fertility specialist will explain the difference between medical fertility preservation and elective fertility preservation and discuss which would be relevant to you.
Flexible payment options
We've partnered with Zip Money to help spread the cost of fertility treatment. With a 12 and 24-month interest-free period and flexible payment options, you can choose what works for you.
Egg freezing success rates
At TASIVF we've had the opportunity to assist with hundreds of egg freezing treatment success stories.
The chance of a live birth from frozen ‘vitrified’ eggs is similar to the chance from ‘fresh’ eggs which are usually used in IVF treatment. The two most important factors that determine the chance of having a baby from frozen eggs are your age when your eggs are frozen and the number of eggs that are stored. Currently, we expect the following success rates for egg freezing:
- For a woman aged 35 or under, one stimulated cycle on average would result in the collection of approximately 10 eggs
- Approximately 90% of eggs would survive the freeze and thaw process
Once an egg survives the freeze and thaw process, we would expect it to behave like a fresh egg:
- Approximately 70% of eggs would fertilise
- 40% develop onto day five (blastocyst embryos)
- A single embryo would have a 45% chance of developing into a pregnancy for women who froze their eggs at 35 years or below
The following graph, published in the journal Human Reproduction in 2017, estimates the probability of a live birth according to how many mature eggs a woman freezes at various ages. The graph shows:
- A woman who freezes 10 eggs under the age of 35 has about a 70 per cent chance of having a baby.
- A woman who freezes 10 eggs at the age of 44 has about an 8 per cent chance of having a baby.
Success rates are lower for women over 35, which is why we recommend being proactive about your fertility sooner rather than later. If you're over the age of 38, egg freezing may not be a suitable avenue. However, there are more immediate options that can be explored such as the use of donor sperm.
We always recommend speaking to a fertility specialist to better understand if egg freezing is an option for your particular circumstances.
Egg freezing FAQs
Can you test your fertility potential now?
The expected success of egg freezing can be ascertained from an initial assessment of the ovarian reserve using a blood test for Anti-Mullerian Hormone (AMH) and an ultrasound scan of the ovaries and uterus. The AMH test can provide insight into the number of eggs remaining, although it does not give information about the quality of the eggs.
This will help your fertility specialist determine if egg freezing is right for you.
Can you freeze your eggs if you have a low AMH?
If you have a low AMH, your fertility specialist will discuss whether egg freezing is a good option. Although the AMH test can provide insight into the number of eggs remaining, it does not give information about the quality of the eggs. Your fertility specialist will consider the results of the AMH test, your age and other individual factors before recommending egg freezing.
Who might consider egg freezing?
You might consider freezing your eggs:
● if your fertility is at risk from a serious illness such as cancer.
● or because you are not in a position to have a baby right now and would like the opportunity to start a family beyond the age at which fertility naturally declines.
If you are contemplating egg freezing, you can also consider other options which may be available to you, such as embryo freezing, donor insemination (for more immediate rather than delayed pregnancy) or the possible use of donor eggs if your own ovarian function is likely to be lost.
How many eggs can you freeze?
Your fertility specialist will discuss the ideal number of eggs required to give you the best possible chance of pregnancy in the future. The number of eggs collected will depend on individual circumstances such as age at the time of the egg collection and other fertility factors. Storage fees include up to 10 eggs per batch.
How long can you freeze your eggs?
You can freeze your eggs for many years until you decide you’re ready to use them. The process of using frozen eggs involves thawing the eggs and finishing the IVF process. The thawed eggs will be fertilised either with your partner’s sperm or donor sperm to create embryos. The best quality embryo will then be transferred into the uterus at the optimal time of your cycle, with the hope of resulting in a pregnancy. Any other embryos created from the thawed batch of eggs will be frozen for future use.
What are the potential risks of egg freezing?
Like most medical procedures, there are potential risks that women may want to consider before they freeze their eggs. Some of the risks include the following:
- Risk of complication during egg collection procedure (although this risk is minimal)
- No eggs being collected
- Some eggs may not survive the freezing process
- Some thawed mature eggs may not fertilise
- Transferred embryos may not result in pregnancy
At TASIVF, our specialists take great care in explaining egg freezing side effects.

For many women not yet ready for parenthood, one option is to put some eggs away for use in the future. A study from the UK and Denmark showed that one in five women considered egg freezing as part of their fertility planning.
