Australian scientists have achieved a significant milestone by producing the world’s first kangaroo embryo through in vitro fertilisation (IVF). This groundbreaking development could play a key role in saving other endangered species from extinction.
The team, led by researcher Andres Gambini, used specimens from eastern grey kangaroos to create embryos. The process involved injecting a single sperm cell into an egg, using a technique known as intracytoplasmic sperm injection (ICSI), which is already used in human and animal IVF procedures. However, the researchers emphasized that achieving a live birth through IVF would require further work and technical advancements.
This success is vital for understanding marsupial breeding and could aid in boosting the genetic diversity of threatened species such as koalas, Tasmanian devils, northern hairy-nosed wombats, and Leadbeater’s possums. Australia, home to the largest variety of marsupial mammals, also faces the highest rate of mammal extinctions in the world. The ability to preserve and enhance the genetic material of these animals is critical for their survival.
The University of Queensland experiment used kangaroo eggs and sperm from deceased animals, as eastern grey kangaroos are not endangered and have healthy populations. The research team is working on refining methods to collect, culture, and preserve marsupial eggs and sperm, which could help conserve these unique species.
IVF has become a powerful tool in global conservation efforts. Last year, scientists achieved the world’s first IVF rhino pregnancy, and in 2018, the first IVF donkey embryo was created. These advancements show how modern reproductive technologies can help protect endangered species and ensure their future survival.
With continued research, IVF may prove crucial in safeguarding Australia’s iconic marsupials, helping to secure their place in the world for generations to come.
