Researchers at the University of Queensland have made history by producing kangaroo embryos through in vitro fertilization (IVF) for the first time. Using a technique similar to human IVF, they successfully created over 20 embryos from eastern grey kangaroos, a species known for its relatively high population. While there are no immediate plans to develop these embryos into live joeys, the breakthrough holds promise for conservation efforts and the understanding of marsupial reproduction.

Australian researchers at the University of Queensland made the eastern grey kangaroo embryos using intracytoplasmic sperm injection , a technique widely used in human IVF, in which a sperm is injected into a mature egg.The team had produced more than 20 embryos using ICSI to date, he said, collecting sperm and egg cells from kangaroos that had recently died at wildlife hospitals.
He added there were no plans to produce live joeys from the IVF embryos, given the species’ abundance. “Our next step is to start getting better at the technology, understanding more of the reproductive physiology … so we can move towards applying the same technology to other marsupials,” he said.
He said IVF would not be a silver bullet for protecting endangered species against extinction, but “just one more tool in our conservation toolkit”, alongside strategies like population monitoring, breeding management and habitat protection.
