IVF Success Rates in Sydney | Dr Simon Nothman | Genea
If you are researching IVF, it is natural to have questions about success rates and what they might mean for you. While these figures can be helpful, they can also be difficult to interpret without understanding how they are measured and what factors may influence outcomes.
Dr Simon Nothman, a fertility specialist at Genea Sydney CBD, supports transparent reporting of IVF outcomes so patients can access independently verified data when considering their treatment options.
The figures below are sourced from YourIVFSuccess, a government-funded website that publishes verified IVF outcome data for accredited Australian clinics that participate in public reporting. All Genea clinics participate in this reporting.
The data spans several reporting periods and measures of treatment success. Across the measures presented below, Genea Sydney CBD’s outcomes are reported as being above the Australian national average.
Why IVF success is measured in different ways
IVF treatment takes place over several stages rather than a single step. From egg collection through to embryo transfer and pregnancy, each stage provides different information about how treatment is progressing.
Because of this, success rates are reported using multiple measures. Each measure reflects a different stage of treatment and timeframe, helping to provide a clearer understanding of how outcomes are reported.
The five measures outlined below cover different reporting periods, providing both longer-term context and the most recent available data from Genea Sydney CBD.
Understanding IVF success rate measures
Measure 1 – Births per complete egg retrieval (including the later transfer of resulting embryos)
A single egg retrieval can result in multiple embryos. These embryos may be transferred straight away or stored and used in future cycles.
This measure reflects the likelihood of a live birth from all embryo transfers, both fresh and frozen, that come from one egg retrieval. By including all embryos created, it provides an overall view of what that cycle may lead to over time.
| Age Group | Genea Sydney CBD | National |
|---|---|---|
| <35 years | 49.9% | 46.4% |
| 35-42 years | 27.1% | 23.6% |
| Egg retrieval year: 2022 | Embryo transfer years: 2022 & 2023 | ||
Measure 2 – Births per first retrieval cycle (including the later transfer of resulting embryos) for women having their first ever egg retrieval
If you are starting IVF, this measure is often one of the most relevant to consider. It reflects the likelihood of a live birth from all embryo transfers resulting from your first egg retrieval.
Because it focuses on first-time cycles, it allows for a more consistent comparison between patients who are new to IVF treatment.
| Age Group | Genea Sydney CBD | National |
|---|---|---|
| <35 years | 55.4% | 52.3% |
| 35-42 years | 37.8% | 30.6% |
| Egg retrieval year: 2022 | Embryo transfer years: 2022 & 2023 | ||
Measure 3 – Births per treatment attempt
This measure reflects the likelihood of achieving a live birth for each treatment cycle in which an embryo transfer takes place. Compared with Measures 1 and 2, it is based on more recent treatment data.
| Age Group | Genea Sydney CBD | National |
|---|---|---|
| <35 years | 43.8% | 34.5% |
| 35-38 years | 33.3% | 28.1% |
| 39-42 years | 23.6% | 16.7% |
| Treatment year: 2023 | ||
Measure 4 – Births per embryo transfer
This measure reflects the likelihood of a live birth for each individual embryo transfer, whether fresh or frozen, within a single reporting year.
| Age Group | Genea Sydney CBD | National |
|---|---|---|
| <35 years | 47.0% | 36.9% |
| 35-38 years | 36.7% | 31.1% |
| 39-42 years | 27.8% | 19.3% |
| Treatment year: 2023 | ||
Measure 5 – Clinical pregnancies per treatment
A clinical pregnancy confirmed by ultrasound is an important step in IVF treatment. This measure shows how often that outcome is achieved for each treatment cycle where an embryo transfer is intended.
Of the five measures, it represents the most recently reported data.
| Age Group | Genea Sydney CBD | National |
|---|---|---|
| <35 years | 54.0% | 41.4% |
| 35-38 years | 43.3% | 35.3% |
| 39-42 years | 28.7% | 24.8% |
| Treatment year: 2024 | ||
Considering your individual circumstances
While IVF success rates can help provide context, they do not tell the full story for any one person.
Your individual chances of success may be influenced by a range of factors, including age, fertility diagnosis, ovarian reserve and overall health. Because of this, these figures are best used as a general guide rather than a prediction.
During your consultation, Dr Nothman will take the time to understand your individual circumstances and discuss how these factors may influence your treatment options and potential outcomes.

What does success on a first IVF cycle mean?
When people refer to success on a first IVF cycle, they are usually referring to Measure 2 (births per first retrieval cycle).
This measure includes all embryo transfers, both fresh and frozen, that come from the first egg retrieval.
How does age affect IVF success rates?
Age is one of the key factors influencing IVF outcomes. Egg quality and egg number tend to change over time, which may affect the likelihood of achieving a pregnancy.
At Genea Sydney CBD, the reported live birth rate per first retrieval cycle is 55.4% for patients under 35, compared with 37.8% for patients aged 35–42.
How should IVF clinic success rates be compared?
When comparing IVF clinics, it is important to review results that are reported using the same measures.
The YourIVFSuccess framework standardises five measures, helping you compare outcomes more consistently across clinics and age groups.
What’s the difference between a specialist’s success rate and a clinic’s success rate?
In Australia, IVF success rates are reported at the clinic level rather than for individual specialists. This means the outcomes reflect results achieved across the clinic where treatment takes place.
Dr Nothman practises at Genea Sydney CBD, and the success rates shown on this page represent the outcomes reported for that clinic.
Can IVF success rates predict my personal outcome?
IVF success rates provide general information based on groups of patients but cannot predict individual results.
During your consultation, Dr Nothman will discuss how your individual circumstances may influence your treatment options and potential outcomes.
Why are there multiple IVF success rate measures?
IVF involves several stages, and different measures are used to reflect outcomes at each stage.
Because of this, no single measure can fully represent the entire treatment process. Looking at more than one measure can help you better understand how outcomes are reported.
