Ethical risks and legal regulation of preimplantation genetic diagnosis
Preimplantation genetic diagnosis technology is widely used as a derivative of assisted reproductive technology,which not only promotes human welfare,but also brings conflicts of interest,uncertainty and ethical risks.According to different purposes,there are currently four main forms of PGD technology application,and the benefits and risks involved in different forms of application are different.The regulation of PGD in various countries generally presents three positions in legislation:laissez-faire,regulation and prohibition,highlighting the complexity and social nature of this issue.Regulatory policies should comprehensively consider the risks posed by PGD to the natural order,human dignity and social justice,and balance the reproductive rights of parents with the best interests of their children to determine the appropriate scope of application.At present,China's regulation of PGD is relative-ly lenient,and to promote the legal transformation of regulation,the legality and application principles,scope and procedures of PGD technology should be clarified through assisted reproduction legislation,the responsibilities of regulatory authorities should be clarified,and a case approval system should be implemented.
