IVF Success Rates in Sydney | Dr Gavin Sacks | Genea Sydney CBD

Understanding your clinic’s success rates is an important part of feeling informed and confident in your care. As a fertility specialist practicing at Genea Sydney CBD, Dr Gavin Sacks believes in complete transparency around IVF outcomes. The figures below are sourced from Your IVF Success, an independent, government-funded platform that publishes outcome data for every accredited IVF clinic in Australia that consents to public reporting. All Genea clinics participate.

The data covers multiple measures across different reporting periods, and across each measure, Genea Sydney CBD’s outcomes are reported above the Australian national average.

Why there are multiple measures

IVF is a process, not a single event — from egg collection through to pregnancy, each stage is measured differently. The five measures below span different reporting periods, and together provide a view of Genea Sydney CBD’s outcomes from historical data through to the most recently available results.

The measures

Measure 1: Births per complete egg retrieval (including the later transfer of resulting embryos)

A single egg collection can produce multiple embryos, which may be transferred over several months. This measure captures the chance of a live birth from all fresh and frozen embryo transfers resulting from one complete egg retrieval cycle, giving you a full picture of what a single retrieval can achieve.

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

Measure 2: Births per first retrieval cycle (including the later transfer of resulting embryos) for women having their first ever egg retrieval

If you’re new to IVF, this measure is particularly relevant to you. It captures the chance of a live birth from all fresh and frozen embryo transfers resulting from a first-ever egg retrieval cycle. Because it focuses only on first-time patients, it provides a consistent basis for understanding outcomes.

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

Measure 3: Births per treatment attempt

This measure shows the chance of a live birth from each individual transfer attempt and reflects more recent data than 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

Measure 4: Births per embryo transfer

This measure shows the chance of a live birth from each individual fresh or frozen embryo that was transferred in one year at Genea Sydney CBD.

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

Measure 5: Clinical pregnancies per treatment

A clinical pregnancy confirmed by ultrasound is an early but meaningful milestone in any fertility journey, and this measure also provides a view of the most recent published results. It shows the chance of reaching that milestone from each individual treatment attempt involving an intended embryo transfer.

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

Your results are personal

Every fertility journey is unique, and success rates are just one part of the picture. Individual outcomes are influenced by many factors including age, diagnosis, and medical history — and no two patients are the same.

Dr Sacks takes the time to understand your full history and circumstances, ensuring your care is tailored to you.

Frequently Asked Questions

Dr Sacks practices at Genea Sydney CBD, where success rates are independently reported through YourIVFSuccess, the government-funded platform that publishes verified outcome data for all accredited Australian IVF clinics. Across every measure and reporting period, Genea Sydney CBD performs above the national average. For first-time IVF patients under 35, the live birth rate with Genea Sydney CBD per first retrieval cycle is 55.4%, compared to 52.3% nationally. For patients aged 35 to 42, that figure is 37.8% versus 30.6% nationally. You can view the full breakdown by age group and measure on this page.

Age is one of the most significant factors in IVF outcomes. At Genea Sydney CBD, where Dr Sacks practices, patients under 35 achieve a live birth rate of up to 55.4% per first retrieval cycle, compared to 37.8% for patients aged 35 to 42. Success rates decline with age due to changes in egg quality and quantity. Gavin will walk you through what this means for your individual circumstances in your first consultation.

The IVF success rate on the first attempt is measured as births per first retrieval cycle (Measure 2). This reflects the chance of achieving a live birth from all fresh and frozen embryo transfers generated from your first-ever egg collection.

At Genea Sydney CBD, the independently reported live birth rate per first retrieval cycle is:

  • 55.4% for patients under 35 (compared to 52.3% nationally)
  • 37.8% for patients aged 35–42 (compared to 30.6% nationally)

These figures are drawn from YourIVFSuccess data (egg retrieval year 2022, embryo transfer years 2022–2023) and provide a clear benchmark for patients beginning their IVF journey. During your consultation, Dr Gavin Sacks will discuss how your age and individual circumstances may influence your personal likelihood of success.

Genea Sydney CBD’s success rates are above the Australian national average across all five YourIVFSuccess measures and all reported age groups. For example, in 2023, births per treatment attempt (Measure 3) were 43.8% at Genea Sydney CBD for patients under 35, versus 34.5% nationally.

Not all success rate figures are directly comparable. Rates can differ based on the patient population a clinic treats, the measures being reported, and the reporting period. When comparing IVF clinic success rates in Sydney, look for clinics that publish all five standardised YourIVFSuccess measures and report data across age groups. This gives you the most complete and accurate picture.

Fertility doctor success rates are not published individually in Australia. Data is reported at the clinic level through YourIVFSuccess, meaning fertility specialist success rates are reflected in overall clinic outcomes. Dr Sacks operates out of Genea Sydney CBD, and the results on this page represent the clinic where your care would take place.

Because IVF involves several stages, no single number tells the whole story. If you’re new to IVF, Measure 2 (births per first retrieval cycle for first-time patients) is most relevant. If you want a broader view of how a fertility specialist and their IVF clinic perform over time, Measures 1 and 2 together provide the strongest basis for comparison. Genea has put together a detailed guide to understanding the YourIVFSuccess measures and how to read the data — you can read it here.

Published success rates are a helpful starting point, but your journey is individual. Outcomes are shaped by factors including your age, ovarian reserve, diagnosis, and medical history — which means the full picture only becomes clear once your circumstances are properly assessed. Dr Sacks takes the time to review your complete history in a consultation, giving you a personalised understanding of what to expect that goes well beyond what aggregate IVF success rates by age can show.
