IVF technology helps appearance
IVF technology is a kind of assisted reproductive technology, which helps couples who cannot conceive naturally to achieve their reproductive aspirations through in vitro fertilization. However, many people have a misunderstanding about IVF technology, believing that this technology can choose the appearance characteristics of infants and pursue the so-called "most beautiful" IVF. However, in fact, IVF technology can not directly affect the appearance of infants, which will be elaborated from four aspects below.

Basic principles of IVF technology
IVF technology mainly includes two basic steps: in vitro fertilization and embryo transfer. In vitro fertilization is to combine eggs and sperm in the laboratory, cultivate embryos, and then transfer the embryos to the female uterus. The whole process will not interfere with or select the embryo's genes, but only help the embryo to carry out auxiliary incubation in the laboratory, so that it can develop in the womb. Therefore, IVF technology cannot directly affect the appearance characteristics of infants.
Infant appearance characteristics are mainly inherited from parents
The appearance characteristics of infants are mainly determined by the parents' genes, which is also true for IVF. Even if the baby is conceived through IVF technology, its appearance characteristics are still mainly determined by the parents' genes. IVF technology only provides a platform for assisted incubation, and it will not make any selection or intervention on genes, so it cannot affect the appearance characteristics of infants.
There are ethical problems in choosing the most beautiful IVF
The purpose of IVF technology is to help couples who cannot conceive naturally achieve their fertility aspirations, and its application in the medical field is usually for therapeutic purposes. Trying to choose the most beautiful IVF seems to meet the psychological needs of some couples, but it actually involves ethical issues. The choice behavior of emphasizing appearance characteristics may have a negative impact on children themselves, and may also have a subversive effect on social values, so it should not be advocated.
conclusion
IVF technology does not directly affect the appearance of infants. The appearance of infants is mainly determined by their parents' genes. Trying to choose the most beautiful IVF involves ethical and moral issues, and the natural characteristics of the baby should be respected. Therefore, the application of IVF technology should be limited to solving the problem of infertility and providing opportunities for couples who cannot conceive naturally.
