Abstract:
The new objective of modern in vitro fertilization-embryo transfer (IVF-ET) is to select and transfer the most competent embryo for a healthy single pregnancy. In order to achieve this goal, it is necessary to transfer single embryo and maximize the live birth rate of single embryo. Since freeze-thaw blastocyst transfer has a higher live birth rate than fresh blastocyst transplantation and better synchronization between embryo and endometrium, it is essential to select the best frozen single blastocyst for transfer. This paper reviews the potential advantages of freeze-thaw single blastocyst transfer, the non-invasive strategies for single embryo selection and the option of blastocysts at different development rates.
