Do frozen embryos provoke implantation failure?

By Zaira Salvador.
Last Update: 08/28/2018

In general, vitrified embryos have a lower implantation rate than those transferred fresh. However, if the embryo is of good quality and the endometrium is receptive, there is no reason for implantation failure.

One consequence of vitrification is the thickening of the zona pellucida, which would require assisted hatching in some cases.
