IVF Success Rates in Queensland
If you are undergoing IVF treatment we know that IVF success rates are important to you, and the below section will help you understand how to interpret IVF statistics.
- How do you measure IVF success?
Currently there is no established industry standard for reporting or defining IVF success.
IVF success rates are sometimes quoted per complete IVF cycle. A complete IVF cycle may involve the transfer of multiple embryos collected from one egg collection. Success rates reported this way will appear higher than success rates reported per embryo transfer.
At The Fertility Centre, we measure IVF success rates as clinical pregnancies (a pregnancy confirmed by a blood test and ultrasound, usually at around 6-8 weeks) per embryo transfer. Unfortunately not every pregnancy will carry to a live birth, so live births are also quoted per embryo transfer.
We report this way to give you the most realistic understanding of your chance of success following each individual embryo transfer.
It is also important to be aware that not every treatment cycle results in an embryo transfer, because sometimes there are no eggs collected or after eggs have been collected no embryos develop so an embryo transfer cannot take place.
To understand IVF success rates it is important to understand what part of the IVF treatment cycle a particular statistic is measuring before you compare them.
There are also other factors that need to be understood before you begin to compare IVF success rates. These include:
- A woman’s age. This is the most important factor determining IVF success rates, so you want to make sure you are comparing rates for woman of the same age.
- Whether the clinic transfers more than one embryo with each transfer. More embryos per transfer may make success rates appear higher. At The Fertility Centre we have a single embryo transfer policy to reduce the risk of multiple births, low birth weight and premature births.
- Whether the success rates data includes techniques such as ICSI and whether it includes frozen embryo transfers or only fresh embryo transfers.
The below graph shows the proportion of The Fertility Centre patients in Queensland who had a clinical pregnancy and live birth from a fresh embryo that was transferred in 2017. The live birth rate ranged from 35% for patients under 30, to 6% per fresh embryo transfer for patients 40 to 44 years.

We recommend that you discuss your individual chance of success with your treating clinician.
