Abstract

Objective: The aim of this study was to evaluate what data exists in the literature about the fate of SCE. Methods: This is an integrative review of papers published in the last ten years, in the Medline and PubMed databases on the subject. Results: the studies included in this review demonstrate that the difficulties in defining the fate of surplus cryopreserved embryos are mainly due to the absence of specific legislation in most countries. Sociocultural and demographic factors such as religion, treatment period, ethnicity, income, marital status, economic status and education level are factors that influence the choice of the final destination of ECE. This study demonstrated that in most of the countries evaluated, the law or regulations do not provide clear guidance on the final destination of the surplus cryopreserved embryos, although it is reasonable to consider that the law will treat embryos, after a certain period of time, as abandoned. Accurate information about the desired destination of the surplus cryopreserved embryos is needed from the beginning of the breeding process to minimize future problems. Conclusions: We conclude that this is a controversial issue, involving ethical, legal, moral and financial issues, that lack specific legislation in almost all of the countries evaluated, which contributes to indecision, abandonment, and it hinders the final destination of these embryos.
