On September 14, 2016 (August 14, 2016 in the lunar calendar), scientists confirmed for the first time that they could reproduce without eggs. Foreign media said that for a long time, people have accepted certain facts that are not controversial, such as water is wet, the earth is round, and sperm and eggs can only reproduce after combining. Later, it was found that the last item may not be true. Taiwan's "Central News Agency" quoted AFP on September 14, 2016 as reporting that scientists announced that they had successfully created mice by combining mouse sperm with a cell that is not an egg. British and German researchers said in a report published in Nature Communications that the surviving mice are healthy, have a normal lifespan, and can also reproduce through traditional methods. "It used to be thought that only egg cells could bind to sperm and allow embryos to develop," said Perry, a researcher at the University of Bath in the UK. "Our research challenges established norms," said Perry. "Since early embryologists first observed mammalian eggs around 1827 and observed fertilization 50 years later, it has been believed that only egg cells can bind to sperm cells and produce offspring." The scientists used a type of mitotic cell called parthenogenote to replace meiotic egg cells to breed mice, the report said. They injected sperm nuclei before parthenogenote divided into two cells to fertilize them. In this mouse experiment, the chance of successful pregnancy was one in four, according to the BBC. "This is the first time scientists have shown that cells other than eggs can combine with sperm to produce offspring," Mr. Perry said, reversing nearly 200 years of thinking.
