Modern society with an increase in the level of its material, scientific and spiritual growth requires the conformity of public relations, especially when it concerns the life and health of citizens. In the conditions of modern development of medical technologies the law that recognizes and protects a person as an individual from birth is currently based on convenience, and not on scientific achievements and principles of law. Progress in the field of assisted reproductive techniques (in vitro fertilization, donation of genetic material, surrogacy, cryopreservation and genetic manipulation of embryos, fetal intrauterine operations) raises a number of new questions about the boundaries of the beginning of life, determining the legal status of the embryo and fetus. A new area of law is being formed — fetal law (fetus — fetus, embryo). The basis of fetal law is the regulations on the legal status of the fetus, its connection with the reproductive rights of women. Just the conflict of interests between the fetus (embryo) and the pregnant woman that remains at the center of the heated disputes in the legal literature today and abroad in legislative authorities and courts, and sometimes on the streets and squares of cities. This is due to uncertainty, the lack of clear criteria established by the law, when legislative and executive authorities are forced to use different approaches, leaving unresolved issues of legal provisions.
