Embryo Transfer and Luteal Phase Support
The main variables affecting pregnancy and implantation rates are uterine receptivity, embryo quality, and transfer efficiency. Much less effort has historically been placed on assessing or maximizing embryo transfer procedures compared with the other aspects of in vitro fertilization. Embryo transfer is usually performed blindly with no attempt to document the variables that might adversely impact pregnancy rates. Physicians too frequently underestimate the importance of the embryo transfer technique and are often unwilling to modify their own personal habits or catheter choices.
