Which country has created the first-ever kangaroo embryos using in vitro fertilisation (IVF)?

Correct Answer: B. Australia

Australian researchers created the first-ever kangaroo embryos using in vitro fertilisation (IVF). This was achieved through intracytoplasmic sperm injection (ICSI), a technique used in human fertility treatments. Scientists from the University of Queensland used ICSI to create eastern grey kangaroo embryos by injecting a single sperm into a mature egg. Over 20 embryos have been successfully produced. The sperm and egg were collected from recently deceased kangaroos in wildlife hospitals. This breakthrough aims to help conserve endangered marsupials like koalas, Tasmanian devils, and wombats, addressing Australia’s high mammal extinction rate.
