University of Queensland researchers are bringing advanced technology to equine breeding in Australia through an advanced form of in vitro fertilisation.
The team, led by UQ’s Dr Andres Gambini, is using an approach called Intracytoplasmic Sperm Injection (ICSI), with exceptional success rates.
“Ovum pick up (OPU) and ICSI involve extracting eggs – also known as oocytes – from ovaries and injecting a single sperm to create an embryo,” Dr Gambini said.
“The technology allows us to bring new, science-backed solutions to breeders nationwide, offering advanced reproductive options that were previously limited in Australia.
“It has unique benefits, including year-round embryo production, the ability to create multiple embryos from just a single straw of semen, and the possibility to utilise the genetics from older, infertile or even deceased animals.
“UQ’s advances in equine reproductive technology are reshaping the Australian breeding landscape, blending scientific expertise with real-world benefits.”
A core research focus is on improving oocyte maturation conditions through enhanced culture media, designed to increase embryo viability and pregnancy success.
The team is also exploring new sperm selection technologies to ensure that only the most viable sperm are used in embryo production, further optimising outcomes.
These advances aim to make equine reproductive technology even more efficient and accessible, positioning UQ’s lab as a leader in equine IVF research globally.
“This project is a powerful example of academia connecting with industry for real-world impact,” Dr Gambini said.
“By partnering closely with the horse breeding industry, UQ ensures that its innovations are immediately applicable to breeders’ needs.
“Through these partnerships, UQ is making advanced reproductive technology available to Australian breeders, helping them tackle challenges like fertility issues, genetic preservation, and efficient breeding cycles with scientifically validated, high-impact solutions.
“With nearly 100 embryos produced in just two months and, an embryo survival rate exceeding 80 per cent after embryo transfer, the lab’s achievements demonstrate the practical value of this research.”
This work not only strengthens the role of science in animal breeding but also underscores the university’s commitment to applying research for the benefit of both industry and animal health.
Through its innovative approach and strong industry ties, UQ’s lab is poised to set new standards for equine breeding across Australia.
