before or during conception is very controversial, and the experiment has been met with both criticism and concern. Scientists warn that a modification can have serious consequences, because it may cause harm to other genes and affect the entire genome for future generations. With the exception of research in the laboratory is the genetic modification is prohibited in a number of countries including Sweden and China.

If the Hes data is true, it is the first time such intervention has been made. But he has not published their findings in any scientific writing, therefore, other researchers have not been able to review the results of the research.

In China stopped the authorities immediately He started an investigation.

to the department of science and technology at the university of Shenzhen, but the experiment is according to the investigation carried out on false pretenses and illegal. According to the investigators were, He probably have used fraudulent documents in order to be able to carry out ivf on the pairs.

After the Hes experiments, researchers have called for an international agreement for guidelines on targeting.
