The past decade has witnessed a rapid increase in the number of frozen-thawed embryo transfer (FET) cycles. Several factors have contributed to the increase in FET cycles, including improvement in culture media, vitrification, and an increase in preimplantation genetic testing of embryos. However, the accelerated trend in FET cycles also suggests that FET may be preferred over fresh embryo transfer. The current review explores the factors that have influenced this practice shift toward preferential FET and why this shift may be premature.
在过去十年中，冻融胚胎移植（FET）周期的数量迅速增加。有几个因素导致了FET周期的增加，包括培养基的改进、玻璃化以及胚胎植入前基因检测的增加。然而，FET周期的加速趋势也表明，FET可能比新鲜胚胎移植更受青睐。本综述探讨了影响这种向优先FET转变的因素，以及为什么这种转变可能为时过早。
