Fertility Care Fertility Preservation and Egg Freezing

There is no single “perfect” age to freeze eggs, because the decision involves a balance between egg quality and the likelihood you may actually need to use them in the future. In general, younger women tend to respond better to ovarian stimulation, produce more eggs, and freeze eggs of better quality. That means freezing in your 20s to early 30s may offer stronger biological outcomes. However, freezing very early is not always the most practical choice, because you may still go on to conceive naturally later and never need to use the eggs.

Paradoxically, the older you are at the time of egg freezing, the more likely it may be that you will need to rely on those eggs in the future, because age-related infertility becomes more likely. At the same time, egg quality and egg number are lower, which can reduce the usefulness of egg freezing. For many women, the most practical balance between likely need and egg quality is often somewhere between the mid-20s and early to mid-30s, but the right timing depends on your circumstances, ovarian reserve, and future family plans.

Dr Huang offers fertility preservation and egg freezing through Genea Melbourne City. Current Victorian treatment costs are listed on the Genea website, and these can change over time. If you have a medical indication for fertility preservation, such as treatment before chemotherapy, you may also be eligible for Medicare rebates in some circumstances.

In Victoria, cryopreserved eggs and sperm may generally be stored for up to 10 years, with the option to apply for an extension in certain circumstances. Storage limits and extension processes are governed by Victorian law and may change over time, so current requirements should be confirmed when treatment is being planned. This is also discussed as part of the mandatory pre-treatment counselling that Genea Melbourne City provides at no additional cost before egg freezing treatment.

No. Egg freezing does not guarantee a future baby. It is better thought of as a way of preserving additional options for the future. Success depends on several later steps, including how many eggs are frozen, how well they survive thawing, whether they fertilise, how the embryos develop, and whether transfer leads to pregnancy.

There is no single number that is right for everyone. The number of eggs needed depends heavily on the age at which they are frozen, because egg quality declines over time. In general, older women usually need more eggs to achieve the same estimated chance of a future baby. This is one reason a fertility assessment can be helpful before deciding whether egg freezing is likely to be worthwhile.

There is no strict age cut-off that applies to everyone, but egg freezing becomes progressively less effective with increasing age because both egg number and egg quality decline. As women get older, they may be more likely to need to rely on frozen eggs in the future, but less likely to obtain enough good-quality eggs in a single cycle for egg freezing to be as useful. Some women may therefore consider more than one egg freezing cycle to accumulate eggs. For example, the Australian Government-funded YourEggFreeze Estimator website indicates that at age 40, around 25 frozen eggs may be needed for an estimated 50% chance of a live birth. In general, the most practical balance between likely future need and egg quality is often somewhere between the mid-20s and early to mid-30s, although the right timing depends on your individual circumstances.
