The development of assisted reproductive technologies (ART) as well as the improvement of the methods used for their implementation caused changes in approaches to the management of patients. The main criterion for the effectiveness of ART is the birth of a healthy child, and many factors contribute to the achievement of this result. The question of the number of transferred embryos necessary to achieve the highest possible rate of live birth and the minimum number of complications in women undergoing ART is still relevant. When ART appeared, tactics of transferring several embryos into the uterine cavity were often preferred in order to increase the effectiveness of the programs or due to the lack of the possibility of embryo cryopreservation. Therefore, the use of ART has been associated for a long time with a high incidence of multiple pregnancies which often pose risks for the health of the mother and newborn, as well as the need for performing traumatic embryo reduction procedures. To date, the prevention of multiple pregnancies is a priority for reproductive medicine specialists, and therefore, in many countries, there is a tendency to choose elective single embryo transfer (eSET) as a preventive measure for multiple pregnancies. For this review, the scientific literature was analyzed to compare the effectiveness of eSET tactics and the transfer of two or more embryos in ART programs; the legal framework on this issue was studied as well. Conclusion: Elective single embryo transfer should be recommended to all patients with a “good” prognosis of establishing pregnancy, since the rate of childbirth in this group is comparable to that in patients with the transfer of two embryos. The possibility of introducing eSET in patients with an “unfavorable” prognosis of pregnancy requires further discussion.
