In the attempts of Chinese scientist Che Jinjuich, eight couples were involved voluntarily – fathers were tested for HIV and mothers were screened for HIV. A pair of the project came out before it stopped.
Che Ġien-kiu, by his experience, surprised most scientists and shocked many. The editing of DNA (called "germ line modification") is a controversial subject and this method – the modification of human DNA – is banned in many countries of the world. These changes in DNA may also occur in the next generation, and some other genes may be damaged. Among the countries where the modification of human DNA is forbidden, there is also the United States and the countries of Europe. In China itself, the situation is not clear. He added that the Chinese authorities had allowed the experiment to do so.
According to available information, the egg in the tube was fertilized by the sperm of the partner, then genetically modified, and then reinserted into the body of the woman. Basically, it was a technique used in artificial insemination with additional gene editing. However, many scientists have said in the meantime that this is a very controversial project from an ethical point of view.

The goal of genetic modification of embryos should be to enable fathers infected with HIV to infect children at lower risk of infection with these viruses, resulting in an incurable immune-acquired syndrome (AIDS). AFP reported that Chei-kui had suspended his experience because of indignation and controversy surrounding his ethical aspect.
