Effect of coasting on the implantation potential of embryos transferred after cryopreservation and thawing

Coasting did not seem to have a detrimental effect on oocyte and embryo quality because the implantation competence of transferred concepti after cryopreservation and thawing was similar to that of controls. However, prolonged coasting (≥3 days) had a subtle negative impact on the post-thaw survival rate.
