If you’re exploring IVF, it’s completely normal 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’re measured and the factors that may influence outcomes.
IVF success rates are commonly reported as the likelihood of achieving a live birth across different stages of treatment.
Dr I-Ferne Tan, a fertility specialist at Genea Sydney CBD, supports transparent reporting so patients can access independently verified data and feel more informed when considering their 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 multiple reporting periods and outcome measures. Across the measures presented below, Genea Sydney CBD’s outcomes are reported as being above the Australian national average. These results are presented using standardised definitions, helping you understand how outcomes are reported across Australia.
IVF treatment does not happen in a single step. It is a process that unfolds over time. 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 across several measures. Each one looks at a different part of the treatment journey and helps provide additional context around how outcomes are reported.
A single egg retrieval can produce more than one embryo. These embryos may be transferred straight away or stored and used in future cycles.
This measure looks at the likelihood of a live birth from all embryo transfers, both fresh and frozen, that come from one egg retrieval. By including every embryo created, it gives an overall view of what that single cycle may lead to over time.
| Age Group | Genea Sydney CBD | National Average |
|---|---|---|
| <35 years | 49.9% | 46.4% |
| 35-42 years | 27.1% | 23.6% |
| Egg retrieval year: 2022 | Embryo transfer years: 2022 & 2023 | ||
If you are starting IVF, this is often one of the most relevant measures to look at. It shows the likelihood of a live birth from all embryo transfers, fresh and frozen, 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 Average |
|---|---|---|
| <35 years | 55.4% | 52.3% |
| 35-42 years | 37.8% | 30.6% |
| Egg retrieval year: 2022 | Embryo transfer years: 2022 & 2023 | ||
This measure reflects the likelihood of a live birth for each treatment cycle in which an embryo transfer takes place. It is based on more recent treatment data compared with Measures 1 and 2.
| Age Group | Genea Sydney CBD | National Average |
|---|---|---|
| <35 years | 43.8% | 34.5% |
| 35-38 years | 33.3% | 28.1% |
| 39-42 years | 23.6% | 16.7% |
| Treatment year: 2023 | ||
This measure reflects the likelihood of a live birth for each individual embryo transfer, whether fresh or frozen. It is based on outcomes recorded within a single treatment year.
| Age Group | Genea Sydney CBD | National Average |
|---|---|---|
| <35 years | 47.0% | 36.9% |
| 35-38 years | 36.7% | 31.1% |
| 39-42 years | 27.8% | 19.3% |
| Treatment year: 2023 | ||
A clinical pregnancy, confirmed by ultrasound, is an important step in IVF treatment. This measure shows how often that stage is reached for each treatment cycle where an embryo transfer is intended.
Among the five measures, it reflects the most recently reported data.
| Age Group | Genea Sydney CBD | National Average |
|---|---|---|
| <35 years | 54.0% | 41.4% |
| 35-38 years | 43.3% | 35.3% |
| 39-42 years | 28.7% | 24.8% |
| Treatment year: 2024 | ||
While IVF success rates can be helpful when comparing clinic outcomes, they do not tell the full story for any one person. Trying to work out which statistic or measure applies most to you can be challenging.
Your individual chances of success can 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 I-Ferne Tan will take the time to understand your individual circumstances and discuss how these factors may influence your treatment options and potential outcomes. All statistics sourced from YourIVFSuccess.
