Researchers in Australia have successfully produced kangaroo embryos through in-vitro fertilization for the first time, marking a significant advancement in conservation efforts for marsupial species that are facing extinction. The breakthrough, led by University of Queensland lecturer Andres Gambini, may help support the conservation of these unique mammals that have experienced a high rate of extinction in Australia.
The use of IVF techniques on kangaroos’ eggs and sperm can provide valuable insights into the early stages of development for marsupial embryos, which differ from other mammals. Kangaroos have a short pregnancy period and embryos can enter suspended animation for several months, making it challenging to study their growth process.
Australia, known for its diverse wildlife, has the highest rate of mammal extinction globally. The country has lost at least 33 mammal species since European settlement, with many of them being marsupials. The Australian government has implemented a “zero extinctions” plan to protect endangered species, aiming to preserve at least 30% of the country’s land mass for conservation.
While kangaroos are not endangered, the IVF breakthrough is seen as a crucial tool for preserving genetic material in other endangered marsupial species native to Australia, such as koalas, Tasmanian devils, and northern hairy-nosed wombats. The research offers hope for safeguarding the unique genetics of these animals through the creation and freezing of embryos.
Although IVF has been utilized to save other endangered species such as rhinos, there is still much to be learned in the field of assisted reproduction for wildlife conservation. Gambini emphasizes that IVF, along with other strategies, can make a significant impact on protecting species at risk and preventing further extinctions.
