Parents are cautious about every issue of their children, especially for families who cannot have children naturally and choose IVF technology, they are worried that the children born from IVF will not be as “good quality” as the children born from natural conception, and they are afraid that IVF babies will grow up to be physically weak and sickly. This has made many people who want to become mothers and fathers through IVF sweat, is this really the case and will IVF babies really be weak and sickly? Is it true that IVF babies have poor IQ? Will IVF babies be different from normal babies in any way? When babies born through assisted reproduction were surveyed in their home environment, it was found that the parents of IVF babies were older, better educated, and had better socioeconomic status than those of naturally conceived babies. This has a lot to do with the growth of the child’s cognitive abilities. Although the chances of multiple pregnancies or low birth weight are greater with assisted reproductive technology, the impact of their family factors may somewhat offset the possible negative health as well as cognitive effects. From this perspective, there is no difference in the developmental potential of IVF and naturally conceived infants; rather, the environment in which they grow up later in life is more important. It has long been a common belief among many people, including many physicians specializing in the field of assisted reproduction, that assisted reproduction treatments are likely to affect the cognitive and developmental abilities of children. This study shows that IVF technology may have a different impact on children than we might expect, and that IVF babies are not “smarter” than naturally conceived babies, if not exactly smarter. It is the influence of the family environment that determines the cognitive development of the child. Instead of worrying about the downsides of IVF, we should strive to provide a healthier environment for our children. More than 5 million IVF babies have been born worldwide. From the birth and growth of the world’s first IVF baby, Louise, who was able to conceive naturally, to the first IVF baby in China who is 29 years old and the first “IVF baby” who became a father with a donor embryo, all of these have allayed people’s concerns about the health of IVF babies and have proven that IVF babies grow up to be the same as normal children in terms of mental and physical development.
