IVF Success Rates in Australia

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.

What is an IVF treatment cycle?

A standard IVF treatment cycle includes

  • Injections with fertility drugs to stimulate a woman’s ovaries (ovarian hyperstimulation);
  • Collection of eggs (or oocytes) from a woman under local anaesthetic, referred to as an ‘oocyte pick up’ or OPU
  • Eggs are fertilised and matured. This may or may not involve a technique called ICSI (intracytoplasmic sperm injection, when a single sperm is injected into each egg to assist fertilisation)
  • An embryo may be transferred to the woman’s uterus, called a fresh embryo transfer; and
  • Any remaining embryos may be frozen and transferred later, during a procedure called a frozen embryo transfer

Once all fresh and frozen embryos from an initial stimulated cycle have been used, the IVF cycle is considered to be complete.

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.
