Embryo transfer success: It is in our hands.

Embryo transfer (ET) is considered as a critical step in the process of in vitro fertilization. Interestingly, studies have consistently shown significant outcome differences between physicians.

This review summarizes the existing evidence regarding the impact of the individual physician performing ET and the techniques used.
