简要总结
Embryo preservation through freezing plays a significant role in human assisted reproduction. It provides an opportunity for patients to have more than one attempt following an ovarian stimulation cycle, thereby decreasing the exposure of patients to exogenous gonadotrophins and improving cumulative pregnancy rates. The purpose of this study is to compare effectiveness of two different freezing methods.
