Queensland Fertility Group’s success rates are amongst the highest in Australia. We attribute our success to the knowledge and experience of our doctors, the skill of our embryologists, investment in the latest technology and commitment to quality control.
Queensland Fertility Group’s high success rates mean that patients require fewer treatment cycles to become pregnant. This is emotionally and physically less demanding and can deliver significant financial savings for patients
We measure our success rates on two levels. The first is our success rate from the initial treatment cycle where fresh embryos are transferred. The second is the cumulative success rate, where patients have extra embryos created and stored in their first treatment cycle. Many of these patients become pregnant with a subsequent frozen embryo transfer; a process which as the table below demonstrates significantly increases their overall chance of conception. A patient aged 25 – 34 years can expect a cumulative success rate of 61% from one complete IVF cycle including subsequent embryo transfers.

IVF = fertilisation of eggs in a dish in the laboratory
ICSI = assisted fertilisation by injecting a sperm into the egg
ET = transfer of embryos to the uterus
FET = frozen embryo transfer
Understanding IVF pregnancy rates
IVF pregnancy rates can be quoted in a variety of ways. The accepted and most common national standard used by IVF groups, consumer groups and accreditation bodies is a pregnancy rate per embryo transfer. At QFG we quote our pregnancy rates in this manner. A pregnancy is defined as a clinical pregnancy where there is evidence of pregnancy tissue e.g. by ultrasound scan, a baby, or sometimes regrettably a miscarriage or ectopic pregnancy.
Why the variations in success rates?
IVF pregnancy rates are very age sensitive. Our 2006 results clearly demonstrate the effect of maternal age on decreasing pregnancy rates.
Different procedures can also lead to different pregnancy rates. In particular, Frozen Embryo Transfer (FET) pregnancy rates are usually lower than fresh embryo transfer (ET) /IVF cycle rates. This may be due to the fact that the best embryos are often transferred at the fresh cycle leaving the others to be frozen.
