What are the differences in IVF technology between China and the United States? Is the United States more successful than China?

The success rate of IVF in China is generally between 30% and 40%. It can be said that there are very few people who succeed at one time in China, and it usually takes 2-3 times. The United States has the most advanced IVF program in the world, and its cutting-edge third-generation IVF PGD/PGS technology ranks first in the world. The average IVF success rate is 70%-80%. Due to technical shortcomings, genetic PGD (pre-transplantation genetic diagnosis) is rarely performed in China, while the United States has a leading advantage in genetic diagnosis PGD technology. In simulating fertilization conditions during the operation, the United States can completely simulate the uterine environment, including humidity, temperature and other conditions, with a high success rate. However, there are large deviations in this link in China, and the insertion into the uterus is different, so the success rate is also low.
