剩余冻存胚胎现状问题及其处置建议

Current status and disposition suggestions of surplus cryopreservation embryos

近年来,辅助生殖技术(ART)临床应用越来越广泛。体外受精-胚胎移植(IVF-ET)周期数增长、获卵方案完善及实验室技术提高,均使助孕过程中产生了大量剩余胚胎。其中多数剩余胚胎长期不用,冻存在生殖中心造成资源浪费,且其管理与处置面临着一系列法律及伦理挑战。本文就剩余冻存胚胎现状问题做一总结,并结合我中心临床经验对其处置提出几点建议,旨在为国家有关部门制定相关政策法规提供参考。

In recent years,assisted reproductive technology(ART)has been widely used in clinical practice.With the growth of in vitro fertilization and embryo transfer(IVF-ET)cycle numbers,the improvement of controlled ovarian stimulation scheme and laboratory technology,resulted in a large number of surplus embryos during the ART treatment.Many of these embryos are cryopreserved for a long time by the reproductive center,causing a waste of medical resources.The management and disposition of surplus frozen embryos face a series of legal and ethical challenges.This study summarizes the current situation of surplus cryopreservation embryos,and puts forward suggestions on the disposal of these embryos based on the clinical experience of our center,so as to provide references for relevant government departments to formulate policies and regulations.
