Judging from the success rate of IVF, I personally don't think we should trust the contents of those intermediary propaganda. After all, no authority can understand this. But the United States is different. The official statistics are given by the government. You can check it on the professional website fertilitysuccessrates. For example, the comprehensive data lists the success rate of IVF in various hospitals. Take the most difficult data 4 1-42 (the older you get, the harder it is). The Southern California Reproductive Center (SCRC Southern California Reproductive Center for short) has the highest success rate, reaching 6 1.9, which is the highest success rate in the United States and can't be compared with general hospitals.
Foreign institutions are very good in equipment and medical teams. For example, SCRC is the first fertility institution with an embryo mirror in the western United States, a top art laboratory and so on. Many IVF hospitals are so good.
Some people think that the cost is high, and we really have to consider whether the economic strength can bear it. Hospitals in the United States clearly price each item and feel that they will not be cheated. It is recommended to consider it in combination with comprehensive conditions.
