Introduction: are we ready to eliminate the transfer of fresh embryos in in vitro fertilization?

Kurt T Barnhart. Fertil Steril. 2014 Jul.

The rationale to freeze all embryos to avoid transfer into a supraphysiologic environment to improve safety and efficacy is compelling, but not yet proven. How do we decide?

Keywords: In vitro fertilization; cryopreservation; embryo transfer; frozen embryo transfer.
