Our Science

We’re fertility pioneers. Our research and technologies virtually doubled IVF success rates for patients in the mid-nineties and our constant search for innovations and breakthroughs continues to improve outcomes today.

Our expertise in the science of fertility is a direct result of our commitment to funding research. At Genea we have a long and proud history of investing in research and taking innovations from the lab into our clinics, enabling us to help more of our patients (and patients from clinics around the world) realise their dream of creating a family.

We invest by far the most of any Australian clinic with at least 10 per cent of our annual revenue on average going back into research - and substantially more over the past few years. That investment has led to many fertility breakthroughs over the years and that trend continues with exciting new developments underway. Genea’s science and technology have played a part in bringing over 800,000 babies into the world. And that’s before we introduced the newest members of the Genea family – Gavi and Geri - to labs internationally.

Our history as fertility pioneers

Routine Day 5 Embryo Transfers

Genea was the first clinic in Australia to introduce routine Day 5 embryo transfers. Growing the embryos in the lab a little longer before transferring them lets us determine which embryos have the highest development potential and increases success rates. The time between Day 3 and Day 5 in an embryo’s life is critical because it’s when an embryo switches genetic control from the female’s genome to shared control between the female and male. This can be a point in the development of the embryo where problems occur and waiting to transfer embryos beyond it is far more successful. We have given our patients world leading success rates with this advancement for years, and some other Australian clinics still routinely transfer embryos earlier than Day 5.

Single Embryo Transfer

We were also the first clinic in Australia to introduce routine single embryo transfer. While many clinics transfer more than one embryo to try to improve their chances of success, our technology allows us to achieve high success rates while transferring a single, carefully selected embryo.

Vitrification versus the old slow freeze method

Genea was the first clinic in Australia (it’s becoming a little repetitive isn’t it?) to develop and routinely replace the old slow freezing method for embryos, eggs and sperm with the more efficient and successful vitrification process. The technology, which is similar to snap freezing, has dramatically increased survival rates for thawed embryos. We’ve been using it routinely since February 2006 but some clinics still use the outdated slow freeze method.

Our background in developing fertility technologies extends beyond Gavi and Geri.


Genea’s embryologists are experts in embryos need to survive and grow. So before Geri, back in the 1990s they developed a mini incubator that simulated the natural environment of human fallopian tubes by using low oxygen levels and introducing just the right amount of carbon dioxide to help embryos grow. The mini incubators or MINCs also maintained the optimal temperature to reduce stress on the embryo.
