IVF success rates
Measure 1: Births per complete egg retrieval cycle (including the later transfer of resulting embryos).
This measure provides a patients overall chance of a live birth from any given egg retrieval cycle.
This measure shows the chance of a live birth from fresh and frozen embryo transfer procedures resulting from each complete egg retrieval cycle performed in one year at all Genea Clinics.
Starting cohort year (2017): Cycles initiated in 2017 calendar year where an egg retrieval procedure took place.
Follow-up period (2017-2018): Subsequent embryo transfers performed in 2017 and 2018 resulting from the egg retrieval procedures in 2017 and 2018.
Age is female age at time the cycle was initiated (based on cycle date).
Includes autologous cycles only (where a woman intended to, or used her own eggs).
Measure 2: Births per complete egg retrieval cycle (including the later transfer of resulting embryos) for women having their first ever egg retrieval.
This measure provides a patients overall chance of a live birth from their first ever egg retrieval cycle.
This measure shows the chance of a live birth from fresh and frozen embryo transfer procedures resulting from each complete egg retrieval cycle for women having their first ever egg retrieval in one year, at all Genea Clinics.
Starting cohort year (2017): Cycles initiated in 2017 calendar year where an ART naïve woman’s first -ever egg retrieval procedure took place.
Follow-up period (2017-2018): Subsequent embryo transfers performed in 2017 and 2018 resulting from the ART naïve woman’s first-ever egg retrieval procedure in 2017 and 2018.
Age is female age at time the cycle was initiated (based on cycle date).
Includes autologous cycles only (where a woman intended to, or used her own eggs).
Measure 3: Births per individual treatment attempt.
This measure provides a patients chance of a live birth from any given treatment within a cycle with the intention to transfer an embryo (fresh or frozen).
This measure shows the chance of a live birth from each individual treatment attempt involving an intended embryo transfer that was started in one year at all Genea Clinics.
Cycles initiated in the most recent calendar year where live birth data is nationally reported (2018).
Age is female age at time the cycle was initiated (based on cycle date).
Includes autologous cycles only (where a woman intended to, or used her own eggs).
Measure 4: Births per embryo that is transferred.
This measure provides a patient chance of a live birth from any embryo transfer within a cycle (fresh or frozen).
This measure shows the chance of a live birth from each individual fresh or frozen embryo that was transferred in one year at all Genea Clinics.
Cycles initiated in the most recent calendar year where live birth data is nationally reported (2018).
Age is female age at time the cycle was initiated (based on cycle date).
Includes autologous cycles only (where a woman intended to, or used her own eggs).
All data supplied directly to Genea by Australia and New Zealand Assisted Reproduction Database (ANZARD) prior to YourIVFSuccess website establishment. Data are combined from all Genea sites for time periods described in each Measure. For individual Genea sites and further breakdown please visit the YourIVFSuccess website or discuss with yourFertility Specialist or the Genea Fertility Advisor.
For further information on understanding success rates, please refer to the Fertility Society of Australia’s “Interpreting pregnancy rates: a consumer guide”.
Age significantly impacts fertility. Very few women over the age of 45 conceive using their own eggs, unless they freeze their eggs or embryos when they are younger, this is represented in the frozen embryo transfer live birth success rates.
Note: Many factors can contribute to the likelihood of achieving a pregnancy or a live birth such as the cause of infertility, lifestyle (such as weight and smoking) and age. It is important to note that unfortunately not every treatment cycle will result in an egg collection, embryo transfer or having embryos to freeze.
