试管婴儿的定义

试管婴儿是指通过体外受精（IVF）技术将卵子和在实验室中结合成胚胎，然后将胚胎移植到母体子宫内发育成婴儿。这项技术最早由英国的Robert G. Edwards和Patrick Steptoe于1978年成功实施，是一项革命性的生育技术。

In vitro fertilization (IVF) is a process of fertilization where an egg is combined with sperm outside the body, in vitro. The process involves monitoring and stimulating a woman's ovulatory process, removing an ovum or ova (egg or eggs) from the woman's ovaries and letting sperm fertilize them in a liquid in a laboratory. The fertilized egg (zygote) is then transferred to the patient's uterus with the intent to establish a successful pregnancy.

试管婴儿的历史

试管婴儿技术的发展经历了数十年的探索和突破。1978年，世界上第一个试管婴儿路易斯·布朗诞生，这一事件被认为是人类生殖医学史上的重大突破。随后，试管婴儿技术在世界范围内得到广泛应用，为无法自然受孕的夫妇带来了生育的希望。

The development of IVF technology has gone through decades of exploration and breakthroughs. In 1978, the world's first test-tube baby, Louise Brown, was born, which was considered a major breakthrough in the history of human reproductive medicine. Subsequently, IVF technology has been widely used worldwide, bringing hope of reproduction to couples who cannot conceive naturally.

试管婴儿的成功率

随着科技的不断进步，试管婴儿技术的成功率也在不断提高。根据统计数据，全球范围内，IVF的成功率已经达到了40%左右，而且随着医疗技术的不断创新，这一数字还在不断提升。

With the continuous advancement of technology, the success rate of IVF technology has also been increasing. According to statistics, the success rate of IVF has reached around 40% worldwide, and with the continuous innovation of medical technology, this number is still increasing.
