The so-called IVF does not actually develop into a fetus in a test tube, but the early stages of sperm-egg union and embryo development (about 2-5 days) are done in a culture fluid, and the development of the embryo after implantation into the mother’s uterus is exactly the same as natural conception. History: In 1978, the world’s first “test-tube baby” was born in the United Kingdom through assisted reproductive technology. In 1992, the first case of intracytoplasmic single sperm injection (commonly known as second-generation IVF) was successfully performed in Belgium. Wang Yanqiu, Reproductive Center, Shanghai Tongji Hospital Assisted reproductive technology in China started late but developed rapidly. In 1988, the first IVF case was born in China and the second generation IVF was born in 1996. Nearly one million IVF babies have been born worldwide and no adverse effects of IVF surgery on mothers and babies have been found. Hundreds of thousands of IVF babies have been born in China.
