Aussie scientists develop breakthrough in IVF treatment

12.2% boost in live birth rates for people hoping to conceive

SYDNEY, UNDER EMBARGO FOR 10AM 11 JUNE 2021: Pioneered by Australian scientists, a new incubator combined with an updated version of the fluid embryos develop in, has resulted in a staggering 12.2% increase in the number of live births for those struggling to conceive*. The cutting-edge technology is the closest yet to emulating what occurs in the mother’s womb, allowing embryos to grow undisturbed, mirroring the journey in the mother’s fallopian tubes prior to implantation.

Available exclusively to patients of Genea, the Geri® incubator takes photos of an embryo every five minutes at up to 11 different cross sections, it then collates the images to share detailed time lapse footage on a screen, allowing scientists to review embryos without exposing them to undesirable conditions such as variations in temperature. In addition, the fluid embryos develop in, known as culture medium, no longer needs changing and can be used across all stages of embryonic growth.

Genea Fertility Specialist Dr Cheryl Phua says, “traditionally, IVF clinics have used incubators that have more than one patients’ embryos in a single chamber with no time lapse camera, meaning the incubator had to be opened every time one patient’s embryo needed checking and/or when the medium, needed to be changed.” She added, “the significant reduction in disturbance has led to this boost in live birth rates, an incredible result that is testament to Genea’s commitment to increasing the chance of a patient having a baby.”

The results are further evidence that there is a difference between the technologies offered in IVF labs and reflect the figures published on the new Government funded YourIVFSuccess website. Launched in February, independent analysis showed that 6 out of the top 10 IVF clinics in NSW and the ACT were Genea clinics.
To mark the significant announcement, Genea shares video captured on the Geri® incubator of conception occurring and time lapse footage of the development of a human embryo over six days. The beginning of life that has been left unseen by the general public, until now.

“The footage is captured clearly, not many get to view their embryo developing, something special for IVF patients who often miss out on so much,” says Genea Scientific Director Steven McArthur. He said the Geri incubator has also allowed embryologists to witness activity previously never seen, “we’re able to view patients’ genetic material coming together, rapid cell division and the hatching of the future placenta ready for implantation.”

When asked what was in the fluid that is also supporting the live birth rates, “a combination of amino acids and salts that are measured out and weighed precisely by highly trained scientists. A true recipe for success.”

About Us
Hi, we’re Genea. We’ve been helping people make babies for over 30 years – that’s a whole lot of tiny feet pitter-pattering across Australia.

We’ve really led the fertility world, in fact our research and technology virtually doubled IVF success rates in the mid-nineties and continues to improve outcomes today. Whilst we share our baby making instruments around the world, in Australia, you’ll only find it with our experts.

And, with us, parents-to-be have a whole fertility team of experts in their corner, they are with them every baby-step of the way. Why? Because we want patients to start their journey knowing they’ve got the best chance of making a little person possible. That’s Genea all over.
Here’s a little information about the cool gadgets we use in our labs to help boost that chance of a little bub.

About Geri, Grow, Gavi and Gems

  • Geri – parents to be- she’s your first babysitter. Our talented scientists grab those beautiful eggs and speedy sperm and then leave them to do their thing in this high-tech womb. It’s a benchtop incubator with individually controlled incubation chambers per patient to minimize disruptive events to the early-stage embryo. This fancy piece of lab tech also has a camera which continuously monitors the embryos as they develop meaning our scientists and patients can all keep an eye on things.
  • Grow – the app that gives people going through IVF a one-up on those who conceive naturally. Oh, and did we say it’s a world first, giving only Genea’s patients 24/7 access to photos and videos of embryos during the five days they hang out in Geri. And that means sharing a video of a developing embryo on social – ultrasound images are so last decade.
  • Gavi – the world’s first automated vitrification instrument. What? Vitrification – it’s the process used to preserve (freeze if you like) eggs or embryos by cooling them to deep sub-zero degrees. It’s basically a freezing robot, Gavi uses an automated, standardized protocol aiming to provide consistent results in vitrification. Trust us, it’s super important!
  • Gems – the liquid gold that Genea patients’ eggs, sperm, embryos all hang out in - the latest generation of Genea’s culture media for embryo cultivation.
