Сurrent problems and prerequisites for the formation of the legal regime of pre-implantation genetic diagnosis (PGD) are considered in Russian legislation with account the existing approaches to determining the legal status of a “pre-implantation” embryo obtained in the framework of the in vitro fertilization procedure (IVF) are discussed. The authors substantiates the conclusion that it is necessary to legally determine PGD as one of the stages of using IVF, as well as establishing generally binding requirements for the procedure, conditions and features of this diagnosis, taking into account the need to minimize the damage caused to the human embryo.

The advent of in vitro fertilization (IVF) marked a watershed in the scientific understanding of the human embryo. This, in turn, led to a renaissance of human embryology, accompanied by the ability to manipulate the human embryo in the laboratory. This ability has resulted in yet further developments: refinements of IVF itself, preimplantation genetic diagnosis, the derivation and extraction of embryonic stem cells, and even various forms of cloning. There are immense social and scientific pressures to utilize the artificial reproductive technologies in ways that have little or no connection with overcoming infertility. As the original clinical goals of IVF have undergone transformation ethical concerns have escalated, so much so that they are condemned by some as illustrations of ‘playing God’, while any babies born via some of these procedures are labelled as ‘designer babies’. Both terms reflect the fear and repugnance felt by some at the interference with the earliest stages of human life by the artificial reproductive technologies. It is at these points that bioethical analyses have an important contribution to make.
