Embryo transfer is arguably the most critical process in the sequential events that encompass an IVF cycle. Several variables play a role in the success of a transfer, including catheter type, atraumatic technique, and the use of ultrasound guidance. The inclusion of hyaluronan in the ET media also has a benefit for implantation. Because of the adverse effects of controlled ovarian hyperstimulation on the endometrium, frozen embryo transfers have demonstrated improved pregnancy rates as well as better obstetric outcomes. This review will talk about various aspects of ET as it is currently performed, variables affecting its success, and methods of optimization.
胚胎移植可以说是体外受精周期一系列事件中最关键的过程。几个变量对移植成功与否有影响，包括导管类型、无创技术以及超声引导的使用。在胚胎移植培养基中添加透明质酸对着床也有好处。由于控制性卵巢过度刺激对子宫内膜有不良影响，冷冻胚胎移植已显示出更高的妊娠率以及更好的产科结局。本综述将探讨当前胚胎移植的各个方面、影响其成功的变量以及优化方法。
