Gene editing promotes health.

The first thing to be clear is that mice and humans are different species. Although they all belong to mammals, their reproductive system, physiological structure and reproductive ability are very different from those of humans. Therefore, scientists let male mice have children, which does not directly mean that it is not a dream for men to have children.

Secondly, this study only artificially fertilized eggs and sperm by gene editing technology under experimental conditions, and then transplanted them into the mother. With the help of the female mouse, the male mouse successfully gave birth to offspring. This process must be carried out under very strict experimental conditions, and the "children" born by these "father" mice also have certain health problems. It can be seen that there are still many uncertainties in the application of this method to human fertility.

Thirdly, in addition to the main function of female reproductive system, it also plays an important role in protecting embryos and newborns. However, there is no mature uterus and other reproductive organs in men, which plays a vital role in the development of embryos and newborns. Therefore, just because scientists let male mice have children does not directly mean that men can also have offspring.

Finally, it is necessary for us to study the physiological and anatomical characteristics of male reproductive system, explore whether male reproductive organs can realize the healthy development of embryos and babies, and protect and manage male reproductive health. Therefore, although it is interesting for scientists to let male mice have children, it does not mean that male children will become a reality.
