What is third-generation IVF? What are the differences between it and previous generations?

Patient's question:

No

Doctor's answer:

Hello, the third-generation IVF also developed on the basis of the previous generation, just like the second-generation. The first-generation IVF resolved the problem of female infertility, and the second-generation IVF addressed the issue of male infertility. However, there is still one problem that troubles infertile patients: how to conceive a healthy fetus. To solve this problem, the third-generation IVF came into being. Some couples have even undergone multiple "trials" and still cannot conceive a healthy fetus. To address this challenge, the third-generation technology emerged.
